Embodiment
By the technology contents, the structural feature that specify the utility model, realized purpose and effect, know clearly below in conjunction with execution mode and conjunction with figs. and give explanation.
With reference to figure 1 and Fig. 2; The utility model bass enhancement mode audio amplifier 100; Comprise casing 11 and the passive radiator 14 and at least one loudspeaker monomer 13 be located on the casing 11; Form sound chamber 12 between said passive type radiator 14 and loudspeaker monomer 13 and the said casing 11, be filled with the damping thing in the said sound chamber 12.In the present embodiment, said loudspeaker monomer 13 has two, is respectively first loudspeaker monomer 131 and second loudspeaker monomer 132 that are positioned at casing 11 two ends.
The preferably, said damping thing is cotton or adhesive-bonded fabric.
With reference to figure 1 and Fig. 5, said passive radiator 14 comprises integrated high-intensity oscillation plate 141, the installing rack 142 of ccontaining said high-intensity oscillation plate 141, and the flexible connection portion 143 that connects said high-intensity oscillation plate 141 and installing rack 142.
The preferably, said high-intensity oscillation plate 141 is high-strength plastic flitch or high-strength metal sheet.Certainly, high-intensity oscillation plate 141 also can by other rigidity better and rubber-like sheet material process.
