Specific embodiment
Below, with reference to accompanying drawing and specific embodiment, the present invention is described further：
Reference picture 1 and Fig. 2, a kind of audio amplifier described in the present embodiment, including a speaker body 1, a loudspeaker 2, a card fixing component 3 and
Some shockproof parts 4.The loudspeaker 2 are fixed on the upper surface of speaker body 1, and the card fixing component 3 is fixed on the side of speaker body 1
Bian Shang, the shockproof part 4 is arranged on the lower surface of speaker body 1.The quantity of the shockproof part 4 can be 4-10.
With reference to reference picture 2, the speaker body 1 includes a housing 10, installs pronunciation board 11, frequency divider on the housing 10
12 with framework 13, and the driver 14 that pronunciation board 11 is fixedly connected.The inner hollow of the framework 13, the mounting frame of pronunciation board 11
Inside 13.Gap 15 is formed between the pronunciation board 11 and housing 10.The frequency divider 12 is located at the gap with driver 14
In 15.Through hole 16 is offered on the housing 10, the through hole 16 is located at the lower section of the loudspeaker 2.The through hole 16 can it is useful radiating and
Amplify, to improve the service life of speaker body 1 and audio.The housing 10 can be rectangular.
The loudspeaker 2 are installed on the housing 10, and are oppositely arranged with the pronunciation board 11.The shockproof part 4 is four, respectively
Shockproof part 4 is separately fixed in the framework 13.An at least shockproof part 4 is respectively provided with four corners of framework 13.This is prevented
Shake part 4 can be the object with certain elasticity such as spring or silica gel, such that it is able to will effectively be produced described in the sound of speaker body 1
Raw sound wave carries out damping by the shockproof part 4 so that speaker body 1 will not produce vibrations, so that the sound that loudspeaker 2 send
Sound tonequality is preferable.
The card fixing component 3 is used to for speaker body 1 to be arranged on multimedia digital equipment, can effectively prevent speaker body
1 is arbitrarily rocked, so as to effectively avoid speaker body 1 during use be collided with other parts, it is ensured that audio amplifier
Normal service life.The card fixing component 3 includes a left card column 31, a right card column 32 and four fixing bolts 33.The left card column
31 are spaced and be arranged in parallel with right card column 32.Four fixings bolt 33 is removable with left card column 31 and/or right card column 32 respectively
