Claims

[Scope of Claim for Utility Model Registration] (1) A front panel, a case body attached to the rear end of the front panel, a board fixed approximately perpendicularly to the front panel inside the case body, and a board attached to the front end of the board from the front. An audio device comprising: a buffer section that is destroyed by a shock exceeding a predetermined value; (2) A front panel, a case body attached to the rear end of the front panel, a board fixed approximately perpendicularly to the front panel inside the case body, and a fixed portion of the board fixed to the case body from the front for a predetermined distance or more. 1. An acoustic device comprising a buffer section that allows the substrate or a member fixed on the substrate to move rearward in response to an impact of the substrate.
