The present invention relates to technology for loudspeaker box field, particularly relate to one and be used in endosome and have on certain cavity volume (preferred sofa) half built-in woofer and application thereof.
Background technology
Along with popularizing of sofa audio amplifier, simply listen to the music and can not meet the requirement of people to commodity diversification.A part of consumer wishes to obtain more powerful low frequency, a part of consumer wishes when supporting with game, except sense of hearing low frequency acoustically meets, also wish the seismaesthesia can experienced on sofa when low frequency breaks out on health, namely health also can experience vibrations when being packed.
Existing sofa audio amplifier all adopts typical phase inverted cabinet as bass box; There are decades in this structure, is commonly used in domestic acoustics, and be a kind of very general application, only moves on sofa and set up into sofa audio amplifier.And in the face of growing consumption demand, this structure can not meet the requirement of people in acoustically diversification.Main cause is that bass box adopts the mode of phase inverting box to be not suitable for sofa audio amplifier.Because traditional audio amplifier adopt phase inverted cabinet structure time, be all loudspeaker front towards user, sonic transmissions distance is orthoscopic, is the most direct.And sofa audio amplifier is after employing phase inverted cabinet structure, bass horn can't towards user, but sound loss is large.Want to allow to use and significantly obtain low frequency.Just must significantly bring to power.At present, in order to promote bass audio, usually adopt the conventional method adding high-power and that strengthen phase inverting box volume and loudspeaker size to strengthen low-frequency sound pressure; If normal employing adds high-power, not only acoustic efficiency is bad, and deducts the acoustic pressure of middle loss, and the bass can heard by user is also still considerably less; Increase vibrations components and parts (volume and loudspeaker size as motor, case) strengthen health seismaesthesia when bass is packed if adopted, 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 object of the present invention is to provide a kind of bass texture good, with low cost half built-in woofer.
Another object of the present invention there are provided the application of described woofer, and it can be used for the product that endosome has certain cavity volume, the more aobvious advantage of the application especially in sofa.Because greatly acoustic efficiency can not only be improved in sofa, reduce the loss of bass energy, and the health of people can be allowed simultaneously also to experience vibrations when being packed.
To achieve these goals, technical scheme of the present invention is as follows:
A half built-in woofer, comprises casing and loud speaker; Described loud speaker is two, described two loud speakers outside casing, back to being arranged in casing.
Preferably, described two loud speakers are symmetrically back to being arranged in casing.
Preferably, described two loud speakers are asymmetricly back to being arranged in casing.
Preferably, described two loud speakers are true loudspeaker, are also provided with an echo cylinder in casing, and described echo cylinder is located in casing, and are fixed therein on the tank wall at a described loud speaker place.
Preferably, in described two loud speakers, one is true loudspeaker, and another is false loudspeaker, and described false loudspeaker are only containing frame and vibration software.
A kind of sofa using described woofer, described sofa is the sofa having certain cavity in body, described woofer half is installed in the bottom of sofa built-inly, and one in described two loud speakers is closed in sofa, and another loud speaker exposed face is to the ground of carrying sofa.
A kind of sofa using described woofer, described sofa is the sofa having certain cavity in 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 sofa, and another loud speaker exposed face is to the metope near sofa.
The present invention includes casing and two loud speakers, two loud speakers outside casing, back to being arranged in casing.Because sofa audio amplifier itself is different from the playback position of multimedia loudspeaker box, adopt double horn symmetrical or asymmetric back to putting, echo cylinder outwardly time send sound wave to metope together with bass horn outwardly, utilize metope to reflect and increase sound wave, simultaneously bass horn inwardly utilizes whole sofa (certainly cleverly, the present invention is not limited to the use on sofa, as long as to have on the product of cavity can) be the characteristic of a cavity, also bass is promoted towards sofa internal radiation, such bass sound wave obtains the enhancing of at least more than 3DB, and evenly.Preferably be used on 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 have impact to audio), on the other hand, the tonequality that sofa not only can allow people acoustically experience, can allow people experience tonequality from sense of touch simultaneously.
This asymmetric or symmetry, back to structure, allows two kinds of sound waves mix and is heard by user; Whole sofa can be driven to vibrate when bass is packed simultaneously, reason is that the vibration area of two loudspeaker is being multiplied, promote the volume of air in increase at double, loudspeaker inwardly can promote, on sponge that air makes in sofa and on framework, to utilize air push sofa to shake.Such use, all except obtaining more powerful bass, can also obtain powerful physical shocks sensation.
In a word, no matter which kind of mode is all the asymmetric or symmetry of two loudspeaker back to, loudspeaker inwardly push away, and form a cavity co-articulation with whole sofa, and loudspeaker are low old to extrapolation, sound wave, by metope or ground return, can not only improve acoustic efficiency greatly, reduces the loss of bass energy; And it is with low cost.Even if sofa does not in use have the body of wall at the back side as reflecting barrier, whole sofa also can be utilized inner for a cavity provides reflection to one of them loud speaker, thus reach required effect.
