Abstract

PURPOSE: To prevent the divided oscillation of a diaphragm and to constantly faithfully reproduce a sound by connecting the vicinity of a part supported by the edge damper of the diaphragm of a plane form to a voice coil.
CONSTITUTION: The voice coil 9 is disposed in a gap between the top plate 2 and the yoke 3 of a magnetic circuit 4 and this voice coil 9 is connected to the peripheral part of the disk form diaphragm 5 through plural bobbin couplings 18 disposed at equal intervals. Accordingly, the driving area of the diaphragm 5 substantially coincides with the support area thereof. Thereby, the divided oscillation of a problem in a centralized driving type speaker, namely, an inconvenience that the support area cannot follow the oscillation of the driving area is avoided to faithfully reproduce the sound in a high frequency range.
