Patent ID: 8223987

Claim:
An attachment structure for a sound generating apparatus comprising: a coupler secured to a vibrator; a bracket attached to a vibration plate; first fixing means for bringing the coupler and the bracket into engagement with each other through screw-like engagement portions having such a pitch that screwing is completed by rotation of the coupler along a spiral which is inclined with respect to a screw axis by a predetermined angle that can be attained by a single turning of a user's wrist without taking the user's hand that holds the coupler off it; and second fixing means for fixing the coupler to the bracket so as to prevent the coupler from rotating relative to the bracket in a direction to loosen the screw engagement from the position screwed by the predetermined angle by the first fixing means, wherein the second fixing means fixes the coupler to the bracket by engagement of claw-like engagement portions with each other in a circumferential direction about the screw axis in the first fixing means.
