Abstract
A kind of audio amplifier is the utility model is related to, especially a kind of guard audio amplifier, including casing, the voice unit being arranged on the casing and the guard shrouded outside the voice unit, it is characterised in that：The hole coordinated with the voice unit is additionally provided with the guard.A kind of guard audio amplifier disclosed in the utility model, by setting the hole coordinated with voice unit in guard, on the premise of guard self-strength and function is ensured, the propagation of voice unit sound wave is not hindered, influence of the guard to voice unit is greatly reduced, tonequality is good, and audio experience is good.
Description
Technical field
A kind of audio amplifier is the utility model is related to, especially a kind of guard audio amplifier.
Background technology
In order to protect loudspeaker and prevent the dust in air from entering audio amplifier internal constraint speaker operation, and also to
Assign audio amplifier more good-looking outward appearance, guard can be typically provided with outside audio amplifier, but traditional guard percent opening is small can hinder to raise
The propagation of sound device sound wave, tonequality is influenceed, reducing audio and audio experience, percent opening conference causes guard rigidly inadequate, and intensity is not
It is enough, it is easily damaged deformation.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of guard audio amplifier attractive in appearance, durable, acoustical sound.
To achieve these goals, the utility model adopts the following technical scheme that：
A kind of guard audio amplifier, including casing, the voice unit and guard that are arranged on the casing, it is characterised in that：
The hole coordinated with the voice unit is additionally provided with the guard.
Preferably, described hole and the concentric setting of the voice unit.
Preferably, described hole and the voice unit area equation.
Preferably, described hole edge is additionally provided with protective layer.
Preferably, the guard is wire netting.
Beneficial effect：A kind of guard audio amplifier disclosed in the utility model, coordinated by being provided with guard with voice unit
Hole, on the premise of guard self-strength and function is ensured, do not hinder the propagation of voice unit sound wave, greatly reduce
Influence of the guard to voice unit, attractive in appearance, durable, tonequality is good, and audio experience is good.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the utility model embodiment；
Fig. 2 is Fig. 1 partial enlarged drawing
Wherein, in figure marked as：1 casing, 2 guards, 3 voice units, 4 holes, 5 protective layers.
Embodiment
To make the purpose of this utility model, technical scheme and advantage clearer, clear and definite, develop simultaneously implementation referring to the drawings
The utility model is further described example.
Such as Fig. 1, a kind of guard audio amplifier disclosed in the present embodiment, including casing 1, the front end face of casing 1 middle part are provided with high pitch
Unit 3, both sides are provided with bass unit (being not drawn into figure), and the front end face of casing 1 is provided with guard 2, and the guard 2 is wire netting,
Sound wave can radiate through guard 2.
Guard can be related to the problem of percent opening, if percent opening is small, hinder Acoustic Wave Propagation, and high frequency sound wave 8kHz-
20kHz, response curve under the frequency of high pitch frequency range can be caused to be deteriorated, so as to which sense of hearing can also be deteriorated because comb-filter effect；Such as
Fruit percent opening is big, can reduce the rigidity of guard 2 again, is all the insufficient strength of guard 2, the potential risk for having deformation.
On the premise of the self-strength of guard 2 and function is ensured, the propagation of voice unit sound wave is not hindered, on guard 2
It is provided with and coordinates with voice unit 3 and concentric hole 4, so can have both reduced influence of the guard 2 to high pitch sound wave, also not
The rigidity of guard 2 can be reduced.
The area of hole 4 and the area equation of the sound basin of voice unit 3, and edge sets equal matcoveredn 5, and it is strong to strengthen edge
Degree, with the edge of mat 2, prevents from damaging guard 2 in routine use, and prevents from causing personnel's scratch due to unexpected.
In order to obtain more preferable Acoustic Wave Propagation effect, the hole coordinated with bass unit can also be set on guard 2.
Preferably, the guard 2 can also be the guard of the other materials in addition to wire netting, such as plastics.
Preferred embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model,
Every equivalent structure made using the utility model specification and accompanying drawing content or equivalent flow conversion, or directly or indirectly fortune
Used in other related technical areas, similarly it is included in scope of patent protection of the present utility model.
