Bone conduction speaker and hearing device using the same

Abstract

Provided is a bone conduction speaker which is excellent in the quality of sound, capable of giving the listener an excellent feeling of volume because the listener can listen to both the bone conduction sound and the air conduction sound produced by the bone vibration and which can be used more safely even out of doors because the listener can listen to external sounds. A listening device using the speaker is also provided. The bone conduction speaker is characterized in that when the speaker is worn in the auricle, parts (4, 5, 6) of the body (1) of the speaker are in contact with the entrance portion of the external auditory canal and / or the periphery of the entrance portion and that the sound pressure produced when the entrance portion of the external auditory canal and / or the periphery of the entrance portion vibrate because of the vibration transmitted from the contact portion can reach the drum through the external auditory canal.

Description

technical field

[0001] The present invention relates to a bone conduction loudspeaker and a listening device using the bone conduction loudspeaker. More specifically, it relates to a bone conduction sound and an air conduction sound based on bone vibration that can be heard together. A bone conduction speaker capable of listening to external sounds by blocking the external auditory canal, and a hearing device using the bone conduction speaker. Background technique

[0002] Hearing devices that use bone conduction speakers are often designed with the understanding that the bone conduction speaker of the hearing device is mainly in contact with the rear peripheral portion of the auricle or the front portion of the tragus to optimize the hearing device. Transmit bone conduction sound. This is because it is generally considered that the peripheral part of the auricle is most suitable as a vibration transmission location.

[0003] However, in general, even if you are called a h...
