An object is to enhance workability in attachment in a sound generating apparatus that generates sound by vibrating a vibration plate with a vibrator while ensuring acoustic performance as good as that achieved by fastening with fine screw threads. Workability in attaching operation is improved while ensuring acoustic performance as good as that provided by fastening with fine screw threads, by providing first fixing portion that brings engagement portions into screw engagement with each other by rotation by a predetermined angle that can be attained by a user without taking his/her hand that holds a coupler off it and second fixing portion for fixing the coupler to a bracket so as to prevent the coupler from rotating relative to said bracket in a direction to loosen the engagement achieved by said first fixing portion.
