PURPOSE:To obtain the damper device of the speaker which has a simple constitution and performs electric-acoustic conversion faith-fully, by forming a reinforcing part which is protruded from the rise part of the damper to the outside. CONSTITUTION:Damper 20 is what is called a rise damper, and rise part 201 is used to fit it to frame 15. In this case, reinforcing part 202 which is protruded from rise part 201 of damper 20 to the outside is formed in a prescribed position of rise part 201. Thus, oscillation in both directions of rise part 201 is reduced by the action of reinforcing part 202, and specially, the nonlinear distortion generated for a large amplitude of coil bobbine 12 is prevented. Consequently, the damper device of the speaker is obtained which has a simple constitution and performs electric- acoustic conversion exactly. |
