Description
Technical field
The utility model is related to a kind of audio amplifier, specifically a kind of audio amplifier with volume fine adjustment function.
Background technology
Audio amplifier is the terminal of whole sound system, and its effect is that audio electric energy is converted into corresponding acoustic energy, and its spoke
Space is mapped to go.It is the extremely important part of sound system, because it is responsible for is transformed into acoustical signal confession electric signal
The ear of people directly listens to so one mission critical, and the sense of hearing that it will be directly with people is come into contacts with, and the sense of hearing of people is very clever
Quick, and there is very strong resolving ability to the tone color of complex sound.Because human ear is exactly evaluated the subjective feeling of sound
The most important standard of one sound system tonequality quality, accordingly, it is believed that the performance height of audio amplifier is to a sound system
Playing quality be to play key effect.
The casing of audio amplifier is during design, and its shape typically uses cubical golden ratio size, has inside it
The size for imitating volume is relevant with the space size in place room, but the volume of a product is fixed, but not chummery
Size more or less difference, therefore cause experience effect to decrease.
The content of the invention
The purpose of this utility model is to provide a kind of audio amplifier with volume fine adjustment function, to solve above-mentioned background technology
The problem of middle proposition.
To achieve the above object, the utility model provides following technical scheme：
A kind of audio amplifier with volume fine adjustment function, including casing, elastic plate, nut, knob, bearing, screw rod, loudspeaker peace
Fill hole, loudspeaker reinforcing plate, top installing plate and screw, the casing is shaped as cuboid, and the front of casing opens up two loudspeakers
Mounting hole, and box inside wall has loudspeaker reinforcing plate, the backboard of the casing positioned at the position composite joint of loudspeaker mounting hole
Inner side sets elastic plate, and elastic plate can be elastic metal sheet, or the good hardwood of the elasticity such as three-bristle cudrania plank, yew plank
Plate, and two sides of elastic plate have been fixedly connected with rubber strip, the width of rubber strip is more than in elastic plate edge to casing both sides
Gap between wall, and the upper and lower ends of elastic plate are connected by screw at the top of the backboard of casing；The middle part of the elastic plate
It is fixedly connected with nut, nut thread connecting screw rod, one end of screw rod is connected to the inner side of loudspeaker reinforcing plate by bearing, and screw rod
The other end connection backboard on the outside of knob.
It is used as further program of the utility model：The backboard of the casing is provided with the installation for being used for installing control board
Hole.
It is used as further program of the utility model：It is mounting hole that the elastic plate, which is used for through the hole of screw,.
It is used as further program of the utility model：Volume maximum between the elastic plate and backboard accounts for casing total measurement (volume)
5%.
Compared with prior art, the beneficial effects of the utility model are：This practicality can carry out effective to the volume of audio amplifier
Control so that height adapt to different area room, reach optimal audio, it is ensured that the experience effect of user.While this reality
With the position composite joint loudspeaker reinforcing plate by loudspeaker mounting hole, overall resonance is reduced, audio is improved.
Brief description of the drawings
Fig. 1 is side structure sectional view of the present utility model.
Fig. 2 is dimensional structure diagram of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Refer in Fig. 1~2, the utility model embodiment, a kind of audio amplifier with volume fine adjustment function, including casing 1,
Elastic plate 2, nut 3, knob 4, bearing 5, screw rod 6, loudspeaker mounting hole 7, loudspeaker reinforcing plate 8, top installing plate 9 and screw 10,
The casing 1 is shaped as cuboid, and the front of casing 1 opens up two loudspeaker mounting holes 7, and the madial wall of casing 1 is located at loudspeaker
The position composite joint of mounting hole 7 has loudspeaker reinforcing plate 8, to improve stability during loudspeaker work, eliminate casing and loudspeaker it
Between resonance, improve audio.
The backboard of the casing 1 is provided with the mounting hole for being used for installing control board, facilitates power supply and the signal of loudspeaker
Output control.
Elastic plate 2 is set, and elastic plate 2 can be elastic metal sheet, or three-bristle cudrania wood on the inside of the backboard of the casing 1
The good hardwood plate of the elasticity such as plate, yew plank, and two sides of elastic plate 2 have been fixedly connected with rubber strip, the width of rubber strip
More than the edge of elastic plate 2 to the gap between the both sides inwall of casing 1, so as to ensure sealing, speaker effect, and elastic plate are improved
2 upper and lower ends are connected to by screw 10 at the top of the backboard of casing 1（Elastic plate 2 passes through the hole of screw to be mounting hole, so as to be
The bending of elastic plate 2 provides surplus）；The middle part of the elastic plate 2 is fixedly connected with nut 3, the threaded connection screw rod 6 of nut 3, screw rod 6
