Title:
BONE CONDUCTION VIBRATOR AND BONE CONDUCTION LISTENING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/238710
Kind Code:
A1
Abstract:
The present application relates to the technical field of bone conduction devices, and in particular, to a bone conduction vibrator and a bone conduction listening device. The bone conduction vibrator comprises a U-shaped iron, a magnet, a voice coil, a conduction sheet, and an electrically conductive damper. A support is provided on the outer side wall of the U-shaped iron. A pad is provided on the support. The electrically conductive damper is connected to the support and electrically connected to the pad. The voice coil is fixed on the electrically conductive damper and electrically connected to the electrically conductive damper. The conduction sheet is connected to the voice coil and located outside the electrically conductive damper. In the present application, the use of an approach of electrifying a voice coil lead with an external power supply avoids the breakage of the voice coil lead caused by friction between the voice coil lead and components in the bone conduction vibrator due to vibration, and improves the stability of products and the quality of the bone conduction vibrator; moreover, when vibrating, the voice coil drives the electrically conductive damper to vibrate, so that the support and the electrically conductive damper vibrate synchronously, thereby producing a good bass effect.
