High Sound Pressure Speaker Unit for Automotive Applications
Hosiden has developed a high sound pressure level speaker for automotive usage.
Equipped with a baffle, this dynamic speaker unit has a 48mm outer diameter (speaker unit:ϕ40mm. Finding use not only for indicators or warnings from the onboard instrumentation, but also a variety of applications, including fire alarms or other alarms. Compared to our conventional products, this speaker unit is capable of a higher sound pressure level of 115dBSPL or more (*1) without compromising its flat frequency characteristics and wide bandwidth of 500Hz to 3350Hz. A vibration-resistant, heat-resistant resin frame made of a heat-resistant polymer film material has been adopted handling temperatures from -40ºC to 105ºC, so reliable, stable operation under harsh conditions is assured. Furthermore, the development and production scheme is compliant with the IATF16949 specification for quality management, assuring automated production with consistent quality.
（*1） Measurement distance: 2cm, Input power: 1W, with measurement fixture attached
