Abstract
A speaker device has a diaphragm, a static part vibratably supporting the diaphragm in a vibration direction and a driving part applying vibration to the diaphragm in response to an audio signal. The driving part is provided at the static part. The driving part includes a magnetic circuit forming a magnetic gap in a direction different from the vibration direction of the diaphragm, a voice coil vibrating along the magnetic gap, and a vibration direction converter part direction-converting the vibration of the voice coil and transmitting the vibration to the diaphragm. The vibration direction converter part includes a link body angle-converting a link part formed between the voice coil and the diaphragm. The static part includes an outer peripheral frame part surrounding the diaphragm and a bridge part bridging the inside of the outer peripheral frame part.
