Document Type and Number:
Japanese Patent JPWO2022153860
Kind Code:
A1
Abstract:
A bone conduction device 1 is provided with a vibration device 3, and an external case 5 that accommodates the vibration device 3. The vibration device 3 is equipped with: an internal case 11; a coil 19 and magnet 21 accommodated in the internal case 11; and a diaphragm 15 capable of vibrating with respect to the internal case 11. A buffer member 7 capable of absorbing vibrations is disposed between the vibration device 3 and the external case 5 of the bone conduction device 1 on a side opposite from a vibration surface 13a of the vibration device 3. The buffer member 7 is an elastic member made of a sponge-like resin, for example, and is able to absorb vibrations through compressive deformation.
