Abstract: A support frame for a thin mini speaker structure thinner than 10 mm includes a main body having a fixing hole, into which a magnet assembly is mounted to locate below a voice coil; two electrically conductive members disposed on the main body; two lead wire holders disposed on the main body between the fixing hole and the electrically conductive members and each defining a lead wire receiving groove thereon; a first damping colloid applied into the lead wire receiving grooves. Two lead wires of the voice coil are set in the first damping colloid in the lead wire receiving grooves and the electrically conductive members to respectively present an outward curved shape. A thin mini speaker lead wire assembling method is also introduced. With the above support frame and method, two ends of the voice coil windings can be directly used as lead wires to save additional tinsel leads.

Abstract: A speaker device includes a main cabinet composed of a cabinet body and a speaker mounted on the cabinet body; an extendable cabinet composed of a bellows tube and a passive diaphragm, the bellows tube having a front end communicably connected to the cabinet body and a rear end closed by the passive diaphragm, and the passive diaphragm being axially aligned with the speaker; and a damping assembly being arranged in the cabinet body and in the bellows tube, and having a front end connected to the cabinet body and a rear end to the passive diaphragm. With these arrangements, the speaker device can have improved bass performance in the entire low-frequency band instead of being limited to only a few low-frequency points.

Abstract: A speaker buffer structure includes an inner ring, an elastic outer ring, and an elastic bridge. The elastic bridge is connected between the outer peripheral edge of the inner ring and the inner peripheral edge of the elastic outer ring. The outer periphery of the elastic outer ring has a side groove. The side groove is used to connect to a through hole of a retaining tab of a sound box. The elastic bridge absorbs vibration from the speaker to improve the damping effect to limit transmission of vibration to an electronic device containing the speaker.
