To provide a speaker acoustic characteristic maintenance device which is capable of saving a space as a whole by reducing a thickness and a size of a speaker box.SOLUTION: A speaker acoustic characteristic maintenance device 10 comprises: a speaker body; and a speaker box 30 which surrounds a periphery of a sound generating surface of the speaker body and has a sound outlet 50. The speaker box 30 has a speaker fixing wall 31, a facing wall 35, and a peripheral wall 40. The sound outlet 50 is provided on the peripheral wall 40. The peripheral wall 40 has: a first bent portion 41 which is formed along the outer periphery of the speaker body 20 when viewed from a direction perpendicular to the speaker fixing wall 31; and second bent portions 43, 43 which are formed to spread to both sides toward the sound outlet 50. The sound outlet 50 is arranged adjacently to the outer periphery of the sound generating surface of the speaker body 20.SELECTED DRAWING: Figure 1

    【課題】スピーカーボックスを薄型・小型化し全体として省スペース化を図れるスピーカー音響特性維持装置を提供する。【解決手段】このスピーカー音響特性維持装置10は、スピーカー本体と、その音発生面の周囲を囲み音出口50が設けられたスピーカーボックス30とを備え、スピーカーボックス30は、スピーカー固定壁31と対向壁35と周壁40とを有し、音出口50は周壁40に設けられ、周壁40は、スピーカー固定壁31に対して垂直な方向から見たとき、スピーカー本体20の外周に沿って形成された第1湾曲部分41と、音出口50に向けて両側に広がるように形成された第2湾曲部分43,43とを有し、音出口50が、スピーカー本体20の音発生面の外周に隣接して配置されている。【選択図】図1
