Abstract: The present invention provides a speaker device which enables abnormal noises due to contact of a coupler diaphragm with a drive diaphragm to be suppressed and a sound quality to be improved. A speaker device (1) includes: a frame (2); a magnetic circuit (3); a voice coil (42); a voice coil bobbin (41); a drive diaphragm (5) with the voice coil bobbin (41) attached thereto; a first edge (6) coupling an outer peripheral side of the drive diaphragm (5) to the frame (2); a coupler diaphragm (7A) positioned coaxially with the drive diaphragm (5); and a second edge (8A) coupling an outer peripheral side of the coupler diaphragm (7A) to the frame (2). In a view in a direction of a central axis of the drive diaphragm (5), the coupler diaphragm (7A) has a smaller size than the drive diaphragm (5), and the second edge (8A) has a larger projected area than the first edge (6).

Abstract: A frame is coupled to a magnetic circuit. The frame includes a plurality of holes which are formed outside the coupling portion and opened toward the magnetic circuit. A case covers the magnetic circuit and the frame, and is opened on a sound radiation direction side. An outer circumferential portion of the case is located on the sound radiation direction side beyond the plurality of holes and forms a first gap with respect to the frame. The first gap is communicated with an opening of the case.
