Abstract

See full text

A sound emission control device comprises a plurality of guides. The guides each include an inlet connected to a branching portion that is configured to oppose a vibrating surface inside an acoustic device, an outlet communicated to the inlet, and a horn-shaped inner wall surrounding a space between the inlet and the outlet. The guides are configured to guide sound that is emitted from the vibrating surface and branched by the branching portion to the outlets that are configured to be communicated to sound emission holes that are provided in the acoustic device and face mutually different directions, respectively.
