LOUDSPEAKER SYSTEM, MOBILE TERMINAL DEVICE, AN ELECTRONIC DEVICE

摘要

There is provided a loudspeaker unit capable of assuring characteristics such a preferable output sound pressure with a simple structure. The loudspeaker unit (100) includes a frame body consisting of a first case (11) and a second case (14). At the center of the upper surface of the first case (11), a sound hole (12) is formed while in the inner surface, a fixing portion (13) is formed. A vibration absorbing body (15) is arranged between the fixing portion (13) and the second case (14). The vibration absorbing body (15) stables the arrangement of the loudspeaker (10) and absorbs mechanical vibration generated from the loudspeaker (10) when the loudspeaker (10) operates, thereby uniformly vibrating the loudspeaker (10), the first case (11), and the fixing portion (13). Thus, the sound irradiated via the sound hole (12) from the loudspeaker (10) and the sound irradiated via the case (11) by the mechanical vibration transmitted from the loudspeaker (10) effectively generate a sound.
