Murata upgrades the acoustic characteristics of worlds thinnest piezoelectric speaker
By optimizing product structure and developing new materials, Murata succeeded in reducing distortion and upgrading the sound pressure level while maintaining the small product size of VSLBP2115E1100 series piezoelectric speaker. In addition to thinner parts, the back panels of Murata’s piezoelectric speakers that are needed for driving the device are smaller. As these speakers are well – suited for use in narrow spaces, they are often employed in compact mobile devices.
With the recent growing trend to use mobile devices continuously for longer and longer periods of time, built – in batteries for these devices are becoming larger and larger. As the size of their batteries increases, the amount of space left for auditory and mechanical parts decreases, creating the need for even smaller and thinner speakers.
