Abstract

A sounding body unit has a sounding body, a mesh section, and a housing mounting the sounding body with the mesh section. The housing has a projection, and the projection is pressed against the mesh section in order to prevent the mesh section from resonating with sounds radiated from the sounding body.

Description

technical field [0001] The present invention relates to a sounding body unit, and more particularly to a sounding body unit used as a structure by which the sounding body is installed in a housing together with a mesh section and the sounding body is prevented from being emitted from the sounding body. The sound resonates. [0002] Incidentally, the sounding body used in the sounding body unit according to the present invention includes not only a loudspeaker that emits sound to the outside, and the sound is produced by a small communication terminal, a telephone, a portable music reproduction equipment, a pocket radio, etc. Generated, also includes, for example, a buzzer for an alarm function. Background technique [0003] In recent years, for example, small-sized communication terminals, telephones, portable music playback devices, pocket radios, etc. have speakers that emit sound to the outside, and speaker nets that are inserted between the speakers and the housing to p...
