Abstract
The utility model relates to a sound equipment, specifically speaking relates to a vocal audio amplifier of box resonance. Including the box to and install main loudspeaker, mainboard, lithium cell and the vibrating diaphragm in the box, mainboard and main loudspeaker fixed mounting are on the inner wall of box front side panel, the vibrating diaphragm is inlayed and is installed on the panel of box front side, the lithium cell electricity is connected on the mainboard, be fixed with the resonance loudspeaker on the inner wall of box rear side panel, resonance loudspeaker and main loudspeaker parallel connection are on the mainboard. The utility model discloses an installed the resonance loudspeaker additional in the inside of audio amplifier, the resonance loudspeaker adsorb to be fixed on the inner wall of box, through the principle of resonance loudspeaker vibration sound production, lets the box of audio amplifier become the supplementary vocal source of audio amplifier, because the audio amplifier be airtight space, the resonance loudspeaker form sound reflecting through vibration audio amplifier box, reflect the sound wave and can more effectively promote the vibrating diaphragm to promote the whole sound effect of audio amplifier.
Description
Technical field
This utility model relates to stereo set, specifically, relates to a kind of casing resonance sounding audio amplifier.
Background technology
At present, card-inserted sound box, the application of Baffle Box of Bluetooth more come extensively, but, existing card-inserted sound box, indigo plant
The sounding of tooth audio amplifier only main loudspeaker by being arranged in casing realize, and overall sound effect has much room for improvement.Separately
On the one hand, audio amplifier is sounding when, and its casing typically can issue sonic vibration in the effect of sound wave, existing
Audio amplifier does not has energy produced by the vibration to sound box and develops further.
Utility model content
The purpose of this utility model is, it is provided that a kind of casing resonance sounding audio amplifier, to solve above-mentioned technology
Problem.
For solving the problems referred to above, this utility model be the technical scheme is that
A kind of casing resonance sounding audio amplifier, including casing, and be arranged in casing main loudspeaker, mainboard,
Lithium battery and vibrating diaphragm, described mainboard and main loudspeaker are fixedly mounted on the inwall of cabinet front panel, described in shake
Film is inlayed and is arranged on cabinet front panel；Described lithium battery is arranged on and is fixed on panel inner wall on rear side of casing
In battery case；Described lithium battery is connected on mainboard；It is characterized in that: on rear side of described casing, panel is interior
Being fixed with resonant horn on wall, described resonant horn and main loudspeaker are connected in parallel on mainboard.
Beneficial effect: compared with prior art, this utility model is in card-inserted sound box or Baffle Box of Bluetooth
Portion has installed resonant horn additional, and resonant horn is absorbed and fixed on the inwall of casing, is sent out by resonant horn vibration
The principle of sound, allows the casing of audio amplifier become the auxiliary sound generation source of audio amplifier, owing to audio amplifier is confined space, and resonance
Loudspeaker form sound reflection by vebrato box body, and reflected sound wave energy more effectively promotes vibrating diaphragm, thus
Promote the overall sound effect of audio amplifier.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The utility model is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings.
With reference to Fig. 1, casing resonance sounding audio amplifier described in the utility model, including casing 1, and it is arranged on
Main loudspeaker 5, mainboard 6, lithium battery 2 and vibrating diaphragm 4 in casing 1, described mainboard 6 and main loudspeaker 5 are fixed
Being arranged on the inwall of casing 1 front panel, described vibrating diaphragm 4 is inlayed and is arranged on casing 1 front panel；
Described lithium battery 2 is arranged on and is fixed on rear side of casing 1 in the battery case of panel inner wall；Described lithium battery 2 electricity
It is connected on mainboard 6.Resonant horn 3, described resonance loudspeaker it is fixed with on the inwall of panel on rear side of described casing 1
3 be connected in parallel on mainboard 6 with main loudspeaker 5.
In this utility model, resonant horn 3 is absorbed and fixed on the inwall of casing 1, by resonant horn 3
The principle of vibration sounding, allows the casing of audio amplifier become the auxiliary sound generation source of audio amplifier, owing to audio amplifier is confined space,
Resonant horn 3 forms sound reflection by vibration casing 1, and reflected sound wave energy more effectively promotes vibrating diaphragm 4,
Thus promote the overall sound effect of audio amplifier.
