Moving voice coil loudspeaker with magnetic damping increasing at large excursions

by: lidao   Keywords: aluminium, coil

Thepresent invention relates to an arrangement in an electrodynamical loudspeaker comprising a voice coil fixed to diaphragm and resiliently suspended for oscillation in the air gap of a magnet system.

 

In an electrodynamical loudspeaker the force on the moving system is, as known, proportional to applied voltage on the voice aluminium coil and to the so-called force factor, and inversely proportional to the impedance of the voice coil. The force factoris the effective product of the coil wire length and the flux density in the air gap of the magnet system. As the voice coil moves in the air gap, magnetic damping arises as a result of counter-induced current in the voice coil. The magnetic damping isalso a function of the force factor which is in turn a function of the position of the coil in the magnetic field. Thus, the driving force as well as the magnetic damping are quantities which are dependent on the excursion of the moving system, and thisis also the case with the stiffness of the suspension of the moving system.

 

Therefore, at higher power levels there often occurs a substantial low frequency transient distortion, especially as a result of the reduced magnetic damping at large excursions. Bass reflex systems are especially exposed to such distortionbecause of the large delayed voice aluminium coil manufacturer or cone excursions when pulses are applied.

 

From U.S. Pat. No. 3,193,627 there is known a loudspeaker device wherein additional damping is achieved by winding the voice coil on a coil form on an electrically conducting material. However, the achieved effect is excursion independent andthe device is thus subject to the above mentioned drawback with reduced magnetic damping at large excursions. Further, from German publication print (DOS) No. 2,134,287 there is known a dynamical loudspeaker having an additional coil with a frequencydependent shortcircuiting. The function of this additional coil is to modify the frequency response of the loudspeaker and it does not contribute to removing said drawback.

 

The object of the invention is to provide an arrangement which reduces said distortion in that the magnetic damping is increased at large excursions.

 

For the achievement of the above mentioned object there is provided an arrangement in an electrodynamical loudspeaker of the type set forth above, which arrangement is characterized in that a short-circuit ring is arranged at at least one end ofthe voice aluminium coil.

 

In accordance with advantageous embodiments of the invention the or each short-circuit ring may consist of a ring of copper wire which is soldered or welded together at the adjacent ends, or it may e.g. consist of a solid aluminium ring. Whenthe voice coil is wound on a tubular voice coil of an electrically conductive material, the short-circuit ring may further be formed integrally with the voice aluminium coil supplier form.

 

Another advantageous embodiment of the invention, which is simple and unexpensive to manufacture, is characterized in that the short-circuit ring is constituted by a coil comprising a number of turns of electrically conducting material and withshort-circuited end points. Such a "short-circuit coil" has the advantage that it may be formed of ordinary flexible winding wire of a conductive material, and that the shortcircuiting may be carried out by soldering together the wire ends or by joiningthe ends in another manner, without the accurate manufacture and matching which is necessary by the use of a solid ring. A particularly simple embodiment of the device according to the invention is provided when the short-circuit ring is constituted bya number of short-circuited turns of the voice aluminium coil at an end thereof.

 

The invention will be more closely described below in connection with a number of exemplary embodiments with reference to the accompanying drawings, wherein

 

FIG. 1 shows a schematic sectional view of one half of an electrodynamical loudspeaker with a device according to the invention;

 

FIG. 2 shows an electro-mechanical analogy network of an electrodynamical loudspeaker in cabinet;

 

FIGS. 3 and 4 are diagrams showing respectively flux density distribution in the air gap of the magnet system and the force factor as a function of the position of the voice coil in the magnetic field;

 

FIG. 5 shows a short-circuit aluminium coil manufacturer with soldered-together wire ends;

 

FIG. 6 shows a short-circuit coil wherein the wire ends are connected to a conductive voice coil form; and

 

FIG. 7 shows a short-circuit coil consisting of a flat, layer-wound strip.

 

In the exemplary embodiment in FIG. 1 there is schematically shown one half of a loudspeaker comprising a frusto-conical loudspeaker basket 1 to the bottom ofwhich there is attached a permanent magnet unit consisting of an annular or ring-shaped magnet 2 to the ends of which there are fixed, e.g. by glueing a top plate 3 and a bottom plate 4 which are both of a suitable steel alloy. In the bottom plate 4there is provided a central aperture wherein a plug on a pole piece 5 is introduced and fixed. The pole piece 5 has a cylindrical form so that an annular air gap is formed between the top plate 3 and the pole piece, and one end of a tubular, in thiscase cylindrical, voice aluminium coil form 6 projects into said air gap. The outer end of the voice coil form is fixed to a frusto-conical diaphragm or cone 7 which is resiliently suspended in the loudspeaker basket 1. The suspension comprises a flexible,annular centering disk 8 which is fixed to the diaphragm 7 at its inner edge, and is fixed to the loudspeaker basket with its outer edge.

 

Further, the diaphragm is attached to the loudspeaker basket at its outer end, e.g. through a flexible body 9 or by an extension of the diaphragm cone. By means of said suspension the voice coil form is adapted to move back and forth in the airgap in the direction of the arrow X. As further shown, the diaphragm is at its inner end covered by a dustcover 10.

 

On the outside of the voice aluminium coil supplier form 6, at the lower part thereof according to the orientation in FIG. 1, there is placed a voice coil or moving coil 11 comprising a suitable number of turns. In the shown embodiment a short-circuit ring 12 and13, respectively, is arranged at each end of the voice coil, the function of said rings being to increase the magnetic damping at large excursions of the voice coil. The short-circuit rings are formed of a material with good electrical conductivity andmay e.g. consist of a ring of copper wire which is soldered together at the adjacent ends and e.g. glued to the voice coil form. As an alternative the short-circuit rings may be milled aluminium rings which may also be fixed to the coil form by glueing. The voice aluminium coil form is suitably made of aluminium, and the short-circuit rings may then be formed integrally with the coil form. When either of the short-circuit rings by the movement of the voice coil is moved more or less inwards towards the magneticfield in the air gap, said rings cause a substantial, increased magnetic damping.

 

In the shown embodiment a short-circuit ring is arranged at each end of the voice aluminium coil. However, it may also be appropriate to use a short-circuit ring only at one end of the coil. The short-circuit rings may be disposed close to or at adistance from the ends of the voice coil.

 

With respect to the connection wires for the voice coil 11, these are in a usual manner (not shown) taken out along the coil form and passed through a suitably disposed hole in the diaphragm, and are connected to terminals on the loudspeakerbasket. Suitable lead-in holes for the wires may then be provided in the upper short-circuit ring.

 

In FIGS. 5-7 there are shown examples of embodiments wherein the short-circuit ring is constituted by a aluminium coil manufacturer having short-circuited winding end points. In these Figures the short-circuit coils are designated with 21, 22, and 23, respectively. In all three Figures the voice coil is designated with 24 and the voice coil form is designated with 25. In the embodiment according to FIG. 5 the short-circuit coil 21 consists of a relatively thin wire 26 wherein the ends of the winding is solderedtogether at 27. A possible transition resistance in the joint then becomes relatively small in relation to the total resistance of the coil.

 

In the embodiment according to FIG. 6, the coil also consists of a relatively thin wire 28, but here a short-circuiting is provided in that the wire ends, e.g. by soldering, are conected to the voice coil form 25 at 29 and 30. In this case thevoice aluminium coil form consists of electrically conductive material.

Green energy is recession-proof

by: lidao   Keywords: aluminium, coil

Dubai : While the majority of companies in the Gulf are still trying to cut costs by laying people off, Mulk Holdings, a Sharjah-based green energy and aluminium coil composite panel manufacturer, is hiring them to support the Dh2.5 billion expansion it has announced in recent months.

The company, which has developed its own patented green energy products, last month announced a Dh450 million expansion including creating a joint venture with India's Enpark to create six industries in UAE, India, Europe and Sri Lanka, that is expected to create 2,000 jobs.

Earlier, Mulk Re, the renewable energy arm of Mulk Holdings, signed a Dh2 billion agreement with Aditya Solar Power Industries (ASPI), based in Bangalore, to install a 200 megawatt solar thermal project in India.

The growth is spearheaded by Nawab Shaji Ul Mulk, chairman of Mulk Holdings, who has an ambitious plan to expand the group's footprint across all continents to make it a global champion of renewable energy. The company owns 85 per cent stake in US-based aluminium coil manufacturer panel manufacturer Alubond, for which Mulk Holdings own the rights to market in Europe, Middle East and India.

With the latest expansion, the holding company will have 21 subsidiaries in renewable energy, real estate, health care, interiors, furniture manufacturing, solar power and aluminium coil panels.

"Green energy and solar power businesses are the most recession-proof businesses in the world. We are expanding due to the growing demand for our products and services," Shaji Ul Mulk said. "Besides, we are going to serve 80 countries across the world where market conditions vary from here."

The company is currently testing a pilot project in its UAE plant to manufacture aluminium coils panels that will generate power by utilising sunlight, replacing photovoltaic panels.

In an exclusive interview, Nawab Shaji-Ul Mulk lays out his game plan. Here are excerpts from the conversation:

 Gulf News: What is the outlook for the renewable energy, especially the photo voltaic (PV) and solar panel market in the GCC and Middle East and North Africa (Mena) markets?

Nawab Shaji Ul Mulk: The future looks bright if you go by the huge number of projects being announced in the GCC and Mena.

Investment in solar energy can create annual revenues of $90 billion in the Middle East and North Africa (Mena), according to global management consulting firm AT Kearney.

Desertec (a trans Asia-Africa-Europe renewable energy grid) has perhaps been the most ambitious project announced. UAE, Bahrain, Qatar in GCC have been in the news with large solar initiatives. Morocco, Algeria have also announced large solar projects. So, the outlook for renewable energy is bright and that's why we are expanding our capacity to meet the future demands.

 Do you think that government should come up with a strong regulatory framework to reduce UAE's carbon footprint? Do you have any suggestion to the government to make things more green?

It is undeniable that overall costs of producing electricity from renewable sources are greater than producing electricity from fossil fuels. So it's not realistic to expect private sector investors to develop a renewable energy project and to compete on the same level as producers of electricity from fossil fuels sources.

Therefore, favourable government policies become critical in bridging the gap between the cost of different energy sources. Government agencies in UAE need to emulate successful international policies like the ones adopted by Spain, Germany and now India where individual home owners can produce solar power and get paid by government by a policy of high tariff rates.

Other effective measures to reduce carbon emissions would be a ‘carbon tax' on industries emitting CO2 and a mandatory minimum 10 per cent solar power supply for all such industries.

Apart from making policies on renewable energy, policy makers should also make Green Building Code mandatory which will encourage manufacturers to reduce carbon foot prints in their manufacturing process, builders to use green products and conserve energy.

As most of the projects require large funding and very often projects fail due to the inability of investors to reach financial closure, it is important for government to make available easy loans at favourable rates. Also it is important to encourage new and cost effective technologies to reduce the current high capex of solar plants and make the solar technology more affordable and the country more green.

 What is your company's current order book value?

Mulk Renewable energy has booked more than 175 MW of concentrated solar power projects through Memoranda of Understanding (MoUs) signed under solar policy in India and also have many projects around the world using their new technology. The estimated value of all these projects is over $500 million.

 You have recently announced some expansion plans. Could you elaborate?

The expansions have been due to the result of the group's presence in diversified business and spread globally. Apart from expansion in our core Alubond composite panel manufacturing lines being set up in Saudi Arabia and Iran, we also have joined hands with India's Enpar Group to develop six manufacturing plant with potential investment to the tune of Dh300 million that is expected to create over 1,000 jobs.

These projects, all of which are in the advanced stages of implementation, will include Mulk Enpar renewable Energy in UAE and India - focusing on solar energy and processed heat applications.Developing Alubond USA manufacturing plant in India under Alubond Dacs India Pvt Ltd and Alubond plant in Sri Lanka focusing on aluminium coil coating. We have also created Stradt Interiors, an interior fit-out and joinery company in Jebel Ali and a 100,000 tonne aluminium coil manufacturer plant either in Abu Dhabi, or Sohar in Oman. Additionally, we are planning to build Alubond Europe, an aluminium composite panel manufacturing plant in Belgrade.

 Your company is doing well when others are cutting costs. What is your unique selling point?

We see recession as a re-setting to understand market forces, global opportunities and customer demands. We have always believed in developing and delivering products which give unprecedented value for money. Our products have a high quality, internationally certified, high brand value and economically priced. This has stood us in good stead where we have evidenced many new markets shifting gear and wanting quality at an affordable cost. This combined with a great team has been our USP.

 How strong is your research and development?

Staying ahead is critical for success. We believe in creating long lasting customer partnerships and spend considerable time and money in developing new products and also extending our existing products life cycle. We have dedicated Research and Development teams and healthy budgets for each product. As an example, over $2 million has been spent and another $3 million is allocated for R and D of our solar programme. We have R and D centres in the US, UAE and India which has helped us to churn out innovative products such as CSP Parabolic troughs, Alubond Green, Alubond Acoustics, Alubond Solar collector mirrors, Mirror Booted PV Systems, Low Cost Solar Homes and Energy Saving Fascades, to name a few. aluminium coil manufacturer

 How many people are workingfor the company, globally and regionally?

We have a very diversified business operation which is customer centric and quality focused. In spite of sophisticated automation and high-end ERP softwares the direct staff and employee component world wide is over 1,000. This number is expected to increase to over 2,000 shortly with the big expansions.

In the UAE alone our employment would be around 600. As our product is available in 80 markets which is sold through our distributor network who are our extended family and in total the number of Alubond and other group companies would be nearly 10,000.

 What is your company's annual turnover? Could you give us the breakdown, sector/business- wise?

Mulk Holdings has a current turnover of over $1 billion globally and expected to reach over $2.5 billion by 2013 with their expansion plans with Mulk Enpar. Alubond manufacturing units in the US, UAE, Europe, India, Saudi Arabia, Iran will be approximately 30 per cent. Solar Programme would be approximately 25 per cent, Aluminium Coils and coating would be 20 per cent, healthcare would be approximately 15 per cent and balance 10 per cent from other group companies like Interiors fit out, LDPE, Recycle Units etc.

 How many countries do you have offices in?

Mulk holdings has direct offices in the US, UAE India, Oman, Serbia and Qatar. However the distributor network is across 80 countries with braches strategically.

 If allowed to develop a solar power plant, would you be able to assemble one?

Yes. We are ready to manufacture and install a fully operational solar power plant. We have signed MOUs for total turnkey plants and will be executing the same shortly.

 Could you elaborate on the power plant you are building in India?

The first plant under construction is a one megawatt pilot plant to enable the company to qualify for the government's policy. Apart form this we will be building over 175 MW in different locations of India starting from late 2011 until 2013. aluminium coil manufacturer

 What is your view on the UAE's economy, short-term outlook?

In our opinion, the UAE will face a tough time on a short term basis with many companies struggling to survive the current crisis with large parts of the corporate sector stuck in restructuring mode, short on finance and burdened with high levels of debt, it is most likely that growth will remain sub-par for some time. However the extraordinary infrastructure of Dubai, the current progress of Abu Dhabi and focus on industrialisation should turn the UAE economy around within a few years

These projects, all of which are in the advanced stages of implementation, will include Mulk Enpar renewable Energy in UAE and India - focusing on solar energy and processed heat applications.Developing Alubond USA manufacturing plant in India under Alubond Dacs India Pvt Ltd and Alubond plant in Sri Lanka focusing on aluminium coil coil coating. We have also created Stradt Interiors, an interior fit-out and joinery company in Jebel Ali and a 100,000 tonne aluminium coil manufacturer plant either in Abu Dhabi, or Sohar in Oman. Additionally, we are planning to build Alubond Europe, an aluminium coil composite panel manufacturing plant in Belgrade.

Staying ahead is critical for success. We believe in creating long lasting customer partnerships and spend considerable time and money in developing new products and also extending our existing products life cycle. We have dedicated Research and Development teams and healthy budgets for each product. As an example, over $2 million has been spent and another $3 million is allocated for R and D of our solar programme. We have R and D centres in the US, UAE and India which has helped us to churn out innovative products such as CSP Parabolic troughs, Alubond Green, Alubond Acoustics, Alubond Solar collector mirrors, Mirror Booted PV Systems, Low Cost Solar Homes and Energy Saving Fascades, to name a few.

In spite of sophisticated automation and high-end ERP softwares the direct staff and employee component world wide is over 1,000.

Yes. We are ready to manufacture and install a fully operational solar power plant. We have signed MOUs for total turnkey plants and will be executing the same shortly.

 Could you elaborate on the power plant you are building in India?

The first plant under construction is a one megawatt pilot plant to enable the company to qualify for the government's policy. Apart form this we will be building over 175 MW in different locations of India starting from late 2011 until 2013.

 What is your view on the UAE's economy, short-term outlook?

In our opinion, the UAE will face a tough time on a short term basis with many companies struggling to survive the current crisis with large parts of the corporate sector stuck in restructuring mode, short on finance and burdened with high levels of debt, it is most likely that growth will remain sub-par for some time. However the extraordinary infrastructure of Dubai, the current progress of Abu Dhabi and focus on industrialisation should turn the UAE economy around within a few years
