Claims

[Claims for Utility Model Registration] (1) A sound emitting hole 3 is formed in the mounting area of the sounding device 5 of the casing 2 of the electrical equipment, and is formed in an annular shape corresponding to the peripheral edge of the sounding device 5 and as required. A sounding device mounting structure for an electrical device in which a first sounding device receiving member 4 having a thickness is provided on the inner surface of the mounting portion, and the sounding device 5 is mounted on the first sounding device receiving member 4. A second sound-producing device receiving member 12 formed in an annular shape and having a required thickness corresponding to the peripheral edge of the sound-producing device 5 is mounted on the printed wiring board 11, and the first sound-producing device receiving member 4 and the second A sounding device mounting structure for an electrical device, characterized in that the sounding device 5 is held between a sounding device receiving member 12. (2) Utility Model Registration Claim The structure for mounting a sound-producing device in an electrical device as set forth in claim 1 is characterized in that a hole is formed that penetrates between the inner peripheral surface and the outer peripheral surface of the second sound-producing device receiving member. A structure for mounting sound-producing devices in electrical equipment.
