Description
Technical field
This utility model relates to sound equipment play-back technology field, a kind of energy-conservation high-fidelity multi-functional audio.
Background technology
In prior art, sound equipment inside cavity uses duroplasts design, and transaudient efficiency and tonequality are the most poor, it is difficult to meet
The high-quality productive life demand of people.
Meanwhile, sound equipment is by agitating air to send sound, and the seismic wave of sound passes to other by air and solid state medium
Equipment and the object of surrounding.And existing sound technique is used and covers energy-absorbing material on the equipment accepted and stop and passed by air
The seismic wave broadcast；Or use buffering energy-absorbing material isolation vibroseis, the method stoping the seismic wave propagated by solid state medium.But
It is that existing sound technique lacks the technical scheme being realized damping by physical method.
Additionally, existing sound equipment there is also is not easy to taking and placing, sound enclosure space outerpace utilizes the shortcomings such as difference.
Summary of the invention
The purpose of this utility model is to provide a kind of energy-conservation high-fidelity multi-functional audio, for achieving the above object, this reality
By the following technical scheme of novel offer: a kind of energy-conservation high-fidelity multi-functional audio, inside power switch control knob, sound equipment
Circuit structure, flexible rubber hose cavity, damping device, the recessed cylinder in casing top；Described power switch control knob is placed under sound enclosure
Portion.
Described sound equipment internal circuit configuration, by D class power negative resistance constant-voltage amplifier and noninductive speaker or woofer
Connect and compose.It is characterized in that: the outfan noninductive speaker of connection of D class power negative resistance constant-voltage amplifier or woofer are just
End, the sampling end of D class power negative resistance constant-voltage amplifier connects noninductive speaker or the negative terminal of woofer, D class power negative resistance
The feeder ear of constant-voltage amplifier connects power supply, and the earth terminal of D class power negative resistance constant-voltage amplifier connects ground；Described speaker is positioned at
In the middle part of sound enclosure.
Described flexible rubber hose cavity 360 degree is placed in sound equipment cavity inner wall.
Described damping device is made up of sucker and damping spring, is placed in bottom sound enclosure and is linked as bottom sound enclosure
Integrally；Described damping spring is placed in sucker top, and is connected as a single entity with sucker.
The recessed cylinder in described casing top, is placed in sound enclosure top, it is simple to sound enclosure taking and placing, it is possible to holding small items.
Compared with prior art, the beneficial effects of the utility model are: this utility model uses Switching Power Supply and D class power
Amplifier technique, uses traditional linear power supply and AB class power amplifier to realize energy-conservation more than 60% on year-on-year basis.This utility model sound equipment chamber
The built-in flexible rubber hose cavity of 360 degree of internal wall, transaudient in hgher efficiency more preferable with tonequality.Additionally, this utility model also has damping effect
The best, it is simple to taking and placing, can the advantage such as holding small items.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1 this utility model and use flexible rubber hose cavity design, the tonequality of efficient audio amplifier, its efficiency is higher than with tonequality
Colleague's technology.Additionally, this utility model can coordinate employing DSP high-speed figure treatment technology as electronic audio frequency processor, so
The audio amplifier of 360 degree of flexible pipe cavitys of Electronic Design and inwall match, music can be recorded and to lose in compilation process
Signal, by regulation equalizer, the mode that EQ compensates gives balance and returns.Inborn defect in electroacoustic trumpet can also be made up,
Such as by DSP operation, voice intermediate-frequency section can be produced even-order harmonic, make sound become to be magnetic.Further, since this reality
Using 7.1 sound channel designs with novel also cooperation, built-in 7 little audio amplifiers, a subwoofer typhon, by DSP to each road sound channel
Carry out audio signal management, by the mathematical difference computing of signal, make whole spatial audio effect full.
Refer to Fig. 1, the recessed cylinder in this utility model sound enclosure top, be placed in sound enclosure top, it is simple to sound enclosure is taken
Put, it is possible to holding small items.
Referring to Fig. 2, this utility model is by arranging damping spring, and when sound equipment operation vibration, damping spring can absorb
Most vibration energy, decreases sound equipment and outwards propagates noise by solid state medium.
Sound equipment internal circuit configuration connection diagram of the present utility model shown in Fig. 3, is amplified by D class power negative resistance constant voltage
Device and noninductive speaker or woofer connect and compose, and it is characterized in that: the outfan of D class power negative resistance constant-voltage amplifier connects
Noninductive speaker or the anode of woofer, the sampling end of D class power negative resistance constant-voltage amplifier connects noninductive speaker or low
The negative terminal of sound speaker, the feeder ear of D class power negative resistance constant-voltage amplifier connects power supply, and the earth terminal of negative resistance constant-voltage amplifier is even
Ground connection.Because D class power negative resistance constant-voltage amplifier counteracts loudspeaker voice coil resistance, noninductive speaker counteracts loudspeaker voice coil electricity
Sense, therefore speaker vibration velocity V=U/B1, in addition to realizing playback acoustic pressure and be constant, also can reduce speaker magnetic flux density B and voice coil loudspeaker voice coil wire
Length 1 strengthens acoustic pressure, and can not only can significantly improve electro-acoustic conversion efficiency, moreover it is possible to thoroughly solve sound system playback acoustic pressure
The low difficult problem big with power consumption of non-constant and electro-acoustic conversion efficiency.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this practicality in other specific forms new
Type.Therefore, no matter from the point of view of which point, all should regard embodiment as exemplary, and be nonrestrictive, this practicality is new
The scope of type is limited by claims rather than described above, it is intended that by the containing of equivalency in claim that fall
All changes in justice and scope are included in this utility model.Should not be considered as any reference in claim limiting
Involved claim.
