Document Type and Number:
WIPO Patent Application WO/2022/024162
Kind Code:
A1
Abstract:
[Problem] The present invention addresses the problem of providing an earphone which can be stably worn on the ear and can continuously acquire biological signals even during exercises or when wearing the earphone for a long period of time, without a complex forming process in which the ear hole cavity, outer ear shape, and the like of a user of a wireless earphone that acquires biological signals are measured for each user to form the earphone. [Solution] An earphone according to the present invention is characterized by comprising: a sound conduit that extends in a uniaxial direction; a speaker that is disposed toward a base end of the sound conduit offset to one side in a direction orthogonal to the uniaxial direction, and outputs sound in the uniaxial direction; a microphone that is disposed on the rear side of the speaker with respect to the sound conduit, and detects vibrations; a wireless communication substrate that is disposed on the rear side of the microphone with respect to the sound conduit; and a housing that includes a front part, a connection part, and a rear part. The front part supports the base end of the sound conduit, expands toward the one side from the base end via an inclined surface inclined with respect to the uniaxial direction, has a disk-shaped base end part that is connected to the other side in the direction orthogonal to the uniaxial direction, and accommodates the speaker. The connection part is connected to the rear side of the front part with respect to the sound conduit, and accommodates the microphone. The rear part is connected to the rear side of the connection part with respect to the sound conduit, expands toward the other side in the direction orthogonal to the uniaxial direction, and accommodates the wireless communication substrate.
