Abstract
The utility model relates to a flexible sound box, comprising a plurality of loudspeakers and the sound box body is made of soft materials, such as sponge, the softness can be adjusted to a great extent; the thickness can also be adjusted and sound box body can be made with high dimensional accuracy using mould method; the material can not produce harmful noise when vibrating fiercely due to the excitation of sound wave.
Description
Technical field
The utility model relates to television set and audio amplifier thereof, particularly a kind of audio amplifier that adopts flexible material to make, and this audio amplifier can be applicable to comprise the CRT television set, the television set of PDP, LCD etc.
Background technology
The audio amplifier that uses in the existing television set, no matter be CRT TV or rear-projection TV, PDP, LCD or the like, generally all use plastics to come audio amplifier in the maker, audio amplifier is installed need be fixed in television set both sides or below, its shortcoming is that cost is higher, and price is more expensive, because audio amplifier itself has the vibrating effect of raising one's voice, itself and being connected of casing also need to adopt the technical measures that alleviate vibrations, otherwise difficulty has the good sound quality effect.
Summary of the invention
The purpose of this utility model is to overcome the high shortcoming of prior art cost, provide a kind of cheap, install simple, need not to adopt again the audio amplifier of special cushion technique, can obviously reduce the die cost and the manufacturing cost of television set, especially be fit to audio amplifier is installed on the television set of casing inside, as traditional CRT TV, rear-projection TV, PDP, LCD or the like.
The utility model provides a kind of audio amplifier that adopts the flexibility material, and as sponge material, it is lower that this material and plastics are compared price, install simple, can reduce die cost and manufacturing cost significantly, the plastics audio amplifier of tonequality and equal volume is compared simultaneously, does not have obvious variation.
The utility model is realized by following technical proposals:
A kind of audio amplifier of flexibility comprises loud speaker, it is characterized in that using flexible material, as sponge, makes a sound box.Sponge is a kind of material of softness, but its pliability can in very large range be adjusted, thickness also can be adjusted arbitrarily, and the method that can adopt mould is produced the very high sound box of precision size, during strenuous vibration, itself can not send harmful noise to this material being subjected to acoustic wave excitation.
The audio amplifier of above-mentioned flexibility, it is to adopt flexible casing to coat the rear portion of loud speaker.
Therefore, the sponge material that can choose certain degree of hardness and thickness is made the casing of small-sized audio amplifier, and loud speaker is installed on the casing, more whole audio amplifier is installed in the TV shell; Loud speaker directly can also be installed on the casing, the sponge casing be installed then it is covered fully from the rear portion.
When this technology of enforcement, sponge is not necessarily only selected in selecting for use of material for use, can use the various flexibility materials that comprise sponge to realize the technical program.
The audio amplifier of described flexibility, it also can be to use flexible material to cooperate rigid material to make casing, promptly adopt rigid material as panel, flexible material coats this panel and loud speaker, adds plastics or metal common implementing as sponge, specifically uses plastics or metal to make Loudspeaker panel, increase the rigidity of Loudspeaker panel, make loud speaker more closely reliable with being connected of casing, other five faces of audio amplifier use sponge, to satisfy the needs of some special type.
Above-mentioned flexible audio amplifier, it is several that its specific structure causes itself and television set ways of connecting to have, and a kind of is open screw hole on the panel of flexible material, and the screw hole that passes panel with screw directly is fixed on the television cabin; Another kind of mode is with the speaker frame lengthening or widens, make speaker frame bigger than flexible casing on length or Width, extend casing, and curve the knuckle of 90 degree at two, screw hole is opened on speaker frame, passes speaker frame with screw and is fixed on the television cabin; The 3rd, casing is stuck on the front shell of television, withstand casing back or side with back cover then, fix casing with this.
With respect to prior art, the following again advantage of the utility model:
1. cost declines to a great extent, flexible material, such as the cost of sponge compares obviously very lowly with plastics, and manufacture craft is simple.
2. owing to adopt the flexibility material as casing, when loud speaker shakes, can not sound, but the vibrations of sound wave are converted into mechanical shock, therefore both absorbed the acoustic wave energy that loud speaker sends backward preferably, avoid these sound waves to be delivered to television rear shell, produce harmful vibrations and noise, make audio amplifier itself can not send abnormal sound again.
To the casing dimensional accuracy require lowly, cooperate easily, be easy to produce in batches.
Description of drawings
Fig. 1 is the front view of the utility model execution mode one;
Fig. 2 is the end view of the utility model execution mode one;
Fig. 3 is the front view of the utility model execution mode two;
Fig. 4 is the end view of the utility model execution mode two.
Embodiment
In the drawings, 1 is front shell of television, and 2 is the casing of soft audio amplifier, and 3 is four screw holes on the Loudspeaker panel, and fore shell 1 stretches out four screw columns, and is corresponding one by one with the position of screw hole 3, and casing 2 is closely linked by four screw holes and front shell of television.
The advantage of present embodiment is simple, and is with low cost, and shortcoming is being connected of audio amplifier and casing not to be very tight, if audio amplifier power is very big, when strenuous vibration, the situation of audio amplifier moment disengaging fore shell may occur, produces unusual sound.
See Fig. 3 and Fig. 4: 4 are front shell of television, and 6 is the casing of soft audio amplifier, the 5th, and speaker frame, the 7th, the screw hole on the front shell of television respectively has one up and down.
This speaker frame is very long, extend beyond the length direction of sound box always, and curve one 90 knuckle of spending, and the top has circular hole, and the 7th, the screw column on the front shell of television, each one up and down, the position faces the circular hole on basin frame top, and screw passes from basin frame tapping, gos deep in the screw column, whole audio amplifier is fixed on the fore shell, and the benefit of this method is that the rigidity of stationary tone box body is enough strong.
The advantage of present embodiment is that being connected of casing and audio amplifier is tight, Loudspeaker panel can bear the bigger power of audio amplifier because the cause that the basin frame is stretched has been strengthened rigidity, and guarantee that audio amplifier does not produce moment shrinking away from theshell phenomenon, install also very simply, shortcoming is because that the basin frame of loud speaker will be done is very long, has increased material cost, simultaneously, on some type, need increase glissando in place that the basin frame is connected with casing, with the vibrations that alleviate loud speaker influencing this and also can increase certain cost to complete machine.
