Title:
SOUND GENERATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/158285
Kind Code:
A1
Abstract:
In a sound generating device according to the present invention, stable vibration of a voice coil (1) is achieved without a damper that supports the voice coil. A vibrator (2) is provided with a bending section (2C) having a deformation part (21) that deforms as a result of vibration of the voice coil (1). The vibrator (2) is formed of a resin member integrally with the bending section (2C). A dust-proof net (4) extending from an inner surface (3a) of a frame (3) towards the voice coil (1) is provided. An inner circumferential section (41) of the dust-proof net (4) is joined to a tinsel wire (6) at a projecting section (42). Stable vibration of the voice coil (1) is realized without resonance of the tinsel wire (6).
