Description
Technical field
The utility model relates to a kind of television set, relates in particular to a kind of television set that comprises the integral type audio amplifier.
Background technology
Present television set does not generally adopt audio amplifier, the loudspeaker of television set directly are rigidly connected by screw and front shell of television, when giving great volume, the vibration meeting that speaker sound causes produces impact to the picture tube of television set, cause the vibration of shadow mask in the picture tube easily, cause shake, the ripple of image, influence the stable and definition of image.The television set that has adopts audio amplifier, but is independent sound box type design, needs die sinking again, has increased cost.
The utility model content
The purpose of this utility model addresses the deficiencies of the prior art exactly, a kind of television set that adopts audio amplifier is provided, reduce the production cost of television set, can guarantee that again sound reaches acoustics simultaneously, and avoid medium and low frequency acoustic shock picture tube shadow mask to bring flating, ripple problem.
For achieving the above object, the technical scheme that the utility model proposes is: a kind of television set, include sound signal reproduction apparatus, casing, described casing includes center 1, described sound signal reproduction apparatus comprises audio amplifier, and described audio amplifier comprises loudspeaker, protecgulum 4, bonnet 2, and described loudspeaker are fixed on protecgulum 4 inside, described bonnet 2 is parts of center 1, and described protecgulum 4 cooperates with bonnet 2 and is fixed on the center 1.
Further, be to strengthen audio amplifier rigidity, reduce the noise that the audio amplifier vibration produces, can in audio amplifier bonnet 2 inner spaces, fix one or more audio amplifier support column 3, can realize by bonding, screw or with bonnet integral type mode such as mould.
For increasing the low-frequency effect of sound, can on Loudspeaker front cover 4, design a phase-reversing tube 5, be hollow in the middle of this phase-reversing tube 5, two ends are openings, and an end connects the audio amplifier space outerpace, and the other end connects the audio amplifier inner space.The shape of this phase-reversing tube 5 can be a cylindrical shape, also can be oval bar shape or any polygonal cylinder shape.
For increasing sound effect, acoustical cotton can also be filled in audio amplifier inside.
The beneficial effects of the utility model are: the audio amplifier bonnet is the part of the big mould of center, only needs to open a secondary Loudspeaker front cover mould in addition again, has not only reduced die cost, and has reduced material consumption, and production cost reduces greatly.A TV approximately can be saved about 20 yuan, produces 40,000 television sets by one month and calculates, and can reduce cost 800,000 yuan, and benefit is obvious.In addition, technical solutions of the utility model have also been taken into account the television image jitter problem, and sound quality is also higher.
Feature of the present utility model and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.
Description of drawings
Fig. 1 represents television set center (the containing the audio amplifier bonnet) front view of a kind of embodiment of the utility model.
Fig. 2 represents television set center (the containing the audio amplifier bonnet) end view of a kind of embodiment of the utility model.
Fig. 3 represents television baffle box protecgulum front view, end view, the rearview of a kind of embodiment of the utility model.
Embodiment
As shown in Figure 1, a kind of execution mode of the present utility model is, a kind of television set includes sound signal reproduction apparatus, casing, and described casing includes center 1, described sound signal reproduction apparatus comprises audio amplifier, described audio amplifier comprises loudspeaker, protecgulum 4, bonnet 2, and described loudspeaker are fixed on protecgulum 4 inside, and described bonnet 2 is parts of center 1, described protecgulum 4 cooperates with bonnet 2 and is fixed on the center 1, and described bonnet 2 inner spaces are fixed with one or more audio amplifier support column 3.This execution mode not only reduces cost, but also audio amplifier rigidity is strengthened, and the noise that the audio amplifier vibration produces obviously reduces.
As shown in Figure 3, another kind of execution mode of the present utility model is, a kind of television set, include sound signal reproduction apparatus, casing, described casing includes center 1, described sound signal reproduction apparatus comprises audio amplifier, described audio amplifier comprises loudspeaker, protecgulum 4, bonnet 2, described loudspeaker are fixed on protecgulum 4 inside, and described bonnet 2 is parts of center 1, and described protecgulum 4 cooperates with bonnet 2 and is fixed on the center 1, and described protecgulum 4 also has a phase-reversing tube 5, described phase-reversing tube 5 is a hollow structure, and an end connects the audio amplifier space outerpace, and the other end connects the audio amplifier inner space.This execution mode not only reduces cost, and loudspeaker part energy backward oppositely can also be poured into the front and superpose, and has strengthened the low frequency part of sound, has increased the weight of the bass effect of audio amplifier.
As shown in figures 1 and 3, the utility model also has a kind of execution mode to be, a kind of television set, include sound signal reproduction apparatus, casing, described casing includes center 1, described sound signal reproduction apparatus comprises audio amplifier, described audio amplifier comprises loudspeaker, protecgulum 4, bonnet 2, described loudspeaker are fixed on protecgulum 4 inside, described bonnet 2 is parts of center 1, and described protecgulum 4 cooperates with bonnet 2 and is fixed on the center 1, and described loudspeaker comprise a loudspeaker and a bass horn, described audio amplifier has two, is arranged in the left and right sides of television set.This execution mode not only reduces cost, and can also realize stereophonic effect, and increases the weight of the bass effect of audio amplifier.
The 4th kind of execution mode of the utility model combines enforcement, better effects if with above-mentioned three kinds of execution modes.
The sound-absorbing silk floss also can be filled in audio amplifier inside.
