Schaumburg, Ill. Taiyo Yuden (U.S.A.), Inc. says its new MLS series of 0.7-mm thick multilayer ceramic piezoelectric speakers are 30% to 50% lighter and consumes up to 50% less power than standard dynamic speakers. Touted as the industry's thinnest speaker, the MLS is compact enough for installation in confined spaces down to 1.0 mm, making it suitable for use in next-generation, ultra-slim portable electronic devices.
Gearing up for volume production, Taiyo Yuden projects that it will produce 1,000,000 units per month by the end of first quarter 2004 with 2,000,000 units per month by first quarter 2005.
Taiyo Yuden said the company's materials science and multilayer fabrication expertise, in conjunction with its piezoelectric technology, which eliminates the magnet that all standard dynamic speakers require for operation, allows the MLS to be manufactured in a standard thickness of 0.7 mm. As a result, the savings in space can be used for additional functionality.
The structural design of the MLS speaker incorporates a recently developed piezoelectric material utilizing Taiyo Yuden's low temperature co-fired ceramics (LTCC) technology and multilayer fabrication techniques. The result is a new line of speakers that offers sound quality and pressure levels matching those of dynamic speakers. Unlike dynamic speakers that need internal space to amplify sound output, the acoustic design of the MLS relies only on its own output power to maintain sound pressure levels and quality, said the company.
The MLS may also be used in emerging high-demand applications such as the convergence of contactless ID (RFID), credit cards and cellular telephones, where magnetic leakage from dynamic speakers poses a risk of data error or loss.
Available in three models, the MLS parts include the MLS20070 (20-mm diameter, 74 dB), MLS23070 (23-mm diameter, 76 dB), and MLS25070 (25-mm diameter, 79 dB). These speakers are also semi-customizable.
The MLS devices are priced at approximately $1.80 each in OEM quantities. Delivery is typically 12 weeks. Price and delivery will vary depending on design specs and quantities.
