A speaker structure 301D 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. The fixing may be achieved using a fixing member (380, figure 20A) and a groove may be provided in the fixing member or the through hole so that the through hole is not completely blocked. The through hole can allow air to pass, facilitating cooling and the release of pressure. |
