It was arranged in the undercut part.

  Specifically, the present invention is directed to a portable device in which a circuit device having a conductive element and a speaker are accommodated in a housing, and the following solution is taken.

  That is, according to the present invention, one of the constituent requirements is that an undercut portion opened inward of the casing is formed on the side wall of the casing. The present invention is characterized in that the holder for holding the speaker is provided integrally with the circuit device, and at least a part of the circuit device is disposed inside the undercut portion of the housing.

  According to the above configuration, since the undercut portion is formed on the side wall of the housing, and the circuit device is arranged in the undercut portion, the internal space of the housing is equivalent to the circuit device arranged in the undercut portion. Can be saved. In addition, since the holder for holding the speaker is provided integrally with the circuit device as a separate piece from the housing, it is not necessary to form a positioning structure such as a speaker housing portion in the housing, and the speaker can be And positioned adjacent to the circuit device.

  Therefore, according to the present invention, components can be efficiently arranged in the internal space of the housing, and a speaker can be attached to the housing with high accuracy.
