To provide an acoustic device and an electronic musical instrument, which are capable of miniaturizing a device case.SOLUTION: A speaker grill 150 is locked to a speaker panel 140 to be attached and fixed, and an elastic member 58 deforms inside a mounting hole 44, and is brought into close contact with a surface of a projection 56 and with an inner face of the mounting hole 44, and the mounting hole 44 being a through hole is blocked by torsionally deforming the projection 56 in a state where the elastic member 58 is interposed between the mounting hole 44 disposed inside a panel-side sealed frame-like section 42 of the speaker panel 140 and the projection 56 of the speaker grill 150. The mounting hole 44 when the speaker grill 150 is attached to the speaker panel 140 is arranged in a position penetrating an acoustic space 10.SELECTED DRAWING: Figure 5 【課題】機器ケースを小型化することができる音響機器及び電子楽器を提供する。【解決手段】スピーカパネル１４０のパネル側密閉枠状部４２内に設けられる取付け穴４４と、スピーカグリル１５０の突起部５６との間に弾性部材５８が介在した状態で突起部５６をねじれ変形させることにより、スピーカグリル１５０をスピーカパネル１４０に係止して取付け固定するとともに、取付け穴４４内部で弾性部材５８が変形し、突起部５６の表面及び取付け穴４４の内面に密着して貫通孔である取付け穴４４が塞がれる。また、スピーカグリル１５０をスピーカパネル１４０に取り付ける際の取付け穴４４は、音響空間１０に貫通する位置に配置される。【選択図】図５
