Murata improves acoustic characteristics of world’s thinnest piezoelectric speaker

Murata has announced it has enhanced the audio characteristics of its ultra thin piezoelectric speaker. Measuring just 0.5 mm in thickness, the VSLBP2115E1100 series is believed to be the world’s smallest piezoelectric speaker. By optimizing the product’s structure and the use of new materials it has been possible to reduce distortion and increase sound pressure level without any change in the speaker’s size. Distortion has been reduced by 50 % in the voice frequency region of 2 to 4 kHz. Sound pressure improvements have been made in the low frequency regions of 1 kHz and below.
