Abstract
The utility model discloses a casing-speaker integrated structure for an ultrathin narrow-frame television. The casing-speaker integrated structure comprises a television rear shell. At least one semi-sealed casing having a sound-making surface is formed on the rear shell through integrated injection moulding. A cover plate and a loudspeaker which are matched with the sound-making surface in size are arranged correspondingly to each semi-sealed casing. Each cover plate is provided with plural sound-making holes and can be detachably fixed at one side of the sound-making surface of the semi-sealed casing. The cover plates and the semi-sealed casings surround to form an approximately-sealed audio mixing cavity having plural sound-making holes. The loudspeakers are positioned in the audio mixing cavity, cones of the loudspeakers are oriented to the sound-making holes, end surfaces of the cones of the loudspeakers facing the sound-making holes form annular flangings, and when the cover plates and the semi-sealed casings are fixedly connected, the flangings are tightly attached on the cover plates to surround the plural sound-making holes. The casing-speaker integrated structure can greatly improve the sound effect of the ultrathin narrow-frame television, reduce the complexity of a sound system, and prevent vibration influences of casing-speaker integration on the television.
Description
Technical field
The utility model relates to a kind of structure of television cabin embedded in sound box, specifically relates to casing audio amplifier integral structure for a kind of ultra-thin narrow-frame TV.
Background technology
At present, the intellectuality of television set and the development of slimming, have higher requirement to television cabin, and in order to adapt to the needs of television set slimming development, the shape-designing of television cabin is just towards the future development of ultra-thin narrow-frame, and by market, accepted gradually.But, the shape-designing of ultra-thin narrow-frame casing is when building excellent appearance, also greatly limit and affected the sound effect of TV, the cone shape of ultra-thin narrow-frame casing loud speaker becomes track type from circle, the direction of speaking goes out/carries on the back out under front going out to become, magnet steel diameter also constantly dwindles, and causes the phenomenon that only has high intermediate frequency sound that wavelength is very little to propagate out, and bass effect is poor.In order to solve the poor problem of bass effect of TV, at present, conventional means be by the reflective woofer integral installation with bass effect in television cabin, but the TV of different model, its internal structure is different, for woofer is installed, often to redesign die sinking, when increasing production cost, connector is more, installs very loaded down with trivial details.

As further improvement of the utility model, described back cover bottom interval integrated injection moulding is formed with two described semiclosed casings.
As further improvement of the utility model, described semiclosed casing is five cube structures, and described cover plate is square plate, and described in several, phonate hole rule on described cover plate is arranged, and described cover plate is positioned at the bottom of described back cover.
As further improvement of the utility model, between described cover plate and described flanging, be provided with the buffer structure for buffering vibration, between described cover plate and described semiclosed casing, be provided with the buffer structure for buffering vibration.
As further improvement of the utility model, the annular gasket of described buffer structure for being made by EVA padded coaming.
The beneficial effects of the utility model are: the utility model provides casing audio amplifier integral structure for a kind of ultra-thin narrow-frame TV, by integrated injection moulding on back cover, form the semiclosed casing with the face of speaking, coordinate the cover plate with phonate hole, form a nearly airtight audio mixing cavity, loud speaker location is located in this audio mixing cavity, the cone of loud speaker is provided with flanging, and sealing paste closes on the cover board, said structure combination has met the sounding key element of reflective woofer, thereby can guarantee the front transmission of sound wave, avoid directly forming loop because of the sound wave of diaphragm of loudspeaker obverse and reverse, cause the phenomenon that only has high intermediate frequency sound that wavelength is very little to propagate out, therefore, can greatly improve the bass effect of ultra-thin narrow-frame TV, reduce the complexity of audio system.In addition, the semiclosed casing of the utility model integrated injection molding, without installing and increasing connector, applies very convenient; Loud speaker is common loudspeaker, and application prospect is extensive.Preferably, back cover bottom interval integrated injection moulding is formed with two described semiclosed casings.Semiclosed casing is five cube structures, and cover plate is square plate, and several phonate holes on the cover board rule are arranged, and cover plate is positioned at the bottom of back cover.It is convenient that said structure is opened mould, is easy to injection mo(u)lding, and several phonate holes on the cover board rule are arranged, and can reach good bass effect, and cover plate is positioned at the bottom of back cover and speaks downwards.
Preferably, between cover plate and flanging, be provided with the buffer structure for buffering vibration, between cover plate and semiclosed casing, be provided with the buffer structure for buffering vibration.Like this, by setting up buffer structure, can effectively reduce the vibrational energy that loud speaker is transmitted to other parts of TV, reduce the impact that casing and audio amplifier integral structure bring to TV.The annular gasket of buffer structure for being made by EVA padded coaming.EVA padded coaming has the effect of good buffering vibration, and therefore can reduce the transmission of loudspeaker operation vibration leads cover plate, produces noise.
