Abstract:
A speaker device includes a vibration generator, a rod-like member, and a sound generator. The vibration generator vibrates when receiving an electrical signal. The rod-like member has a first longitudinal end fixed to the vibration generator. The sound generator is attached to a part of the rod-like member. The sound generator integrally includes a vibration transmitter which has a fibrous structure and a diaphragm which is a sheet and has a fibrous structure. When a fiber direction is defined as a direction in which fibers of a fibrous structure are oriented, a fiber direction of the vibration transmitter and a fiber direction of the diaphragm intersect with each other.
