A speaker structure comprises a main speaker unit 311 having a magnetic circuit portion 320 provided with a first through hole 324. A supporting member 370 has a hole portion 371 communicating with the first through hole, and a second through hole 372 pierced from an inner wall surface of the hole portion to an outer peripheral surface of the supporting member. A sub speaker unit 312 is fixed to the main speaker unit via the supporting member. A weight 350 is fixed on the back face side of the main speaker unit and has a main body portion 351 provided with a third through hole 353. The weight is attached to the main speaker unit in a state where the second through hole, the hole portion, the first through hole and the third through hole communicate mutually. A fixing member may be used to join the various parts via their through holes. Either the fixing member or the through holes may include a groove to allow continued air flow with the fixing member in place, thus allowing cooling and the release of pressure. |
