摘要

PROBLEM TO BE SOLVED: To provide an excellent speaker used for various video audio apparatuses capable of suppressing rolling of a diaphragm of the speaker so as to enhance the sound pressure versus frequency characteristic. SOLUTION: In order to solve the task above, a shaft and an elastic disk 12 are provided to an upper part of a center pole 4 in the speaker of this invention. Placing the disk 12 to an inner circumference of a voice coil 7 can suppress rocking of the voice coil 7 in a vertical motion and prevent rolling of the diaphragm 9 so as to enhance the sound pressure versus frequency characteristic.
