Along with popularizing of sofa audio amplifier, simply listen to the music and can not satisfy people to the requirement of commodity diversification.A part of consumer wishes to obtain more powerful low frequency, a part of consumer wishes when supporting with game, except acoustically sense of hearing low frequency satisfies, also wish when low frequency breaks out and can experience seismaesthesia on the health at sofa, namely health also can be experienced the vibrations when being packed.

Existing sofa audio amplifier all adopts typical phase inverted cabinet as bass box; There have been decades in this structure, generally is used for domestic acoustics, and is a kind of very general application, only moves to and has set up on the sofa into the sofa audio amplifier.And in the face of growing consumption demand, this structure can not satisfy people in the requirement of acoustically diversification.Main cause is that bass box adopts the mode of phase inverting box to be not suitable for the sofa audio amplifier.Because traditional audio amplifier when adopting the phase inverted cabinet structure, all be the loudspeaker front towards the user, the sonic transmissions distance is orthoscopic, is the most direct.And the sofa audio amplifier has been after having used the phase inverted cabinet structure, and bass horn can't be towards the user, but sound loss is large.Want to allow to use and significantly obtain low frequency.Just must significant bring to power.At present, in order to promote the bass audio, usually adopt to add high-power and strengthen the volume of phase inverting box and the conventional method of loudspeaker size strengthens low-frequency sound pressure; If it is high-power that normal employing adds, not only acoustic efficiency is bad, and the acoustic pressure of loss in the middle of deducting, can be also still considerably less by the bass that the user hears; If the health seismaesthesia when adopt increasing vibrations components and parts (such as volume and the loudspeaker size of motor, case) and strengthening bass and be packed, not only bass texture is bad, and take up room greatly, cost is higher, directly affects sales volume.

Summary of the invention

For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of bass texture good, with low cost woofer.

Another purpose of the present utility model has been to provide the application of described woofer, and it can be used for product, the especially more aobvious advantage of the application in sofa that endosome has certain cavity volume.Because in sofa, can not only greatly improve acoustic efficiency, reduce the loss of bass energy, and can allow people's health also experience simultaneously vibrations when being packed.

To achieve these goals, the technical solution of the utility model is as follows:

A kind of half built-in woofer comprises casing and loud speaker; Described loud speaker is two, and described two loud speakers are towards the casing outside, back to being installed in the casing.

Preferably, described two loud speakers are symmetrically back to being installed in the casing.

Preferably, described two loud speakers are asymmetricly back to being installed in the casing.

Preferably, described two loud speakers are true loudspeaker, also are provided with an echo cylinder in the casing, and described echo cylinder is located in the casing, and is fixed therein on the tank wall at a described loud speaker place.

Preferably, one is true loudspeaker in described two loud speakers, and another is false loudspeaker, and described false loudspeaker only contain basin frame and vibration software.

A kind of sofa that uses described woofer, described sofa is the sofa that certain cavity is arranged in the body, described woofer half is installed in the bottom of sofa built-inly, and one in described two loud speakers is closed in the sofa, and another loud speaker exposed face is to the ground of carrying sofa.

A kind of sofa that uses described woofer, described sofa is the sofa that certain cavity is arranged in the body, described woofer half is installed in waist or the back of sofa built-inly, and one in described two loud speakers is closed in the sofa, and another loud speaker exposed face is to the metope near sofa.

The utility model comprises casing and two loud speakers, and two loud speakers are towards the casing outside, back to being installed in the casing.Because the sofa audio amplifier itself is different from the playback position of multimedia loudspeaker box, adopt double horn symmetrical or asymmetric back to putting, the echo cylinder sends sound wave with outwardly bass horn to metope outwardly the time, utilize the metope reflection to increase sound wave, while bass horn inwardly utilizes whole sofa (certainly cleverly, the utility model is not limited to the use on the sofa, so long as have on the product of cavity can) be the characteristic of a cavity, also promote bass towards the sofa internal radiation, the bass sound wave obtains at least above enhancing of 3DB like this, and evenly.Preferably be used on the sofa, main because on the one hand, after sofa places, back to body of wall or ground be the relatively-stationary reflecting barrier (size of reflecting barrier, and the distance of distance all can be influential to audio), on the other hand, sofa not only can allow the people in the tonequality of acoustically experiencing, and can allow the people experience tonequality from sense of touch simultaneously.

This asymmetric or symmetrical back to structure, allow two kinds of sound waves mix by the user and hear; Can when being packed, bass drive simultaneously whole sofa vibration, reason is that the vibration area of two loudspeaker is being multiplied, the volume that promotes air is at double increase, loudspeaker inwardly can promote air do on the sponge of sofa and framework on, utilize the vibrations of air push sofa.Use all except obtaining more powerful bass, can also obtain powerful health vibrations sensation like this.

In a word, no matter which kind of mode, all be two loudspeaker asymmetric or symmetrical back to, loudspeaker inwardly push away, and form a cavity with whole sofa and jointly pronounce, and loudspeaker are low old to extrapolation, sound wave can not only improve acoustic efficiency greatly by metope or ground return, reduces the loss of bass energy; And with low cost.Even if sofa does not in use have the body of wall at the back side as reflecting barrier, also can utilize whole sofa inside is that a cavity is given one of them loud speaker cremasteric reflex, thereby reaches required effect.
