Description

  The present invention relates to a telephone handset that can be used with an ear-mounted hearing aid attached.

  Normally, when making a call using a handset, the earpiece is pressed against the ear so that the sound emitting port of the earpiece faces the ear hole, and the entire ear is covered with the earpiece. However, for users wearing ear-mounted hearing aids (hereinafter simply referred to as hearing aids), the sound intake port of the hearing aid is located at the upper part of the ear. Since the exit does not match, there is a problem that it is difficult to hear the sound emitted from the sound emission port.

As a solution to this problem, there has been proposed a transmitter / receiver that includes a transmitter and a receiver, and a grip that connects them, and is provided with an earphone in the grip, and the receiver can be separated from the grip. In this handset, when the receiving part is separated, a sound emitting hole is formed in the grip part, so that sound emitted from the sound emitting hole to the outside of the handset is collected at the sound intake port of the hearing aid ( For example, see Patent Document 1).
