The utility model discloses a kind of two-way TV loudspeaker boxes spoken in front and back, belong to television baffle box technical field.Solve the problems, such as that the double-sided display face TV A and the face B output different audio signals need two different loudspeakers.Including shell, two loudspeakers, loudspeaker magnetic cylinder and audio signal input line, separate cavities are equipped in the shell, shell is divided into ante-chamber and back cavity by the separate cavities, the setting of two loudspeakers respectively symmetrically is in ante-chamber and back cavity, and the cone of two loudspeakers is arranged outward, corresponding on the opposite side of two loudspeakers to be equipped with loudspeaker magnetic cylinder, audio signal input line is corresponding to be connected on two-loudspeaker magnetic cylinder.The two-way TV loudspeaker box structure spoken in the front and back of the utility model is simple, while being conducive to TV ultrathin design.The function of needing two TV loudspeaker boxes to be realized is replaced with a two-way TV loudspeaker box spoken in front and back.It can be widely used in the display application scenarios that double-sided display etc. needs bidirectional output alternative sounds signal.
Description
Technical field
The utility model relates to television baffle box technical fields, and in particular to a kind of two-way TV loudspeaker box spoken in front and back.
Background technique
With the development of current television, TV is appeared in more and more application scenarios, and double-sided display TV is as one
The emerging terminal presentation facility of kind appears in the public places such as airport, station.In the face double-sided display TV A, the face B can be shown
Hold, this requires double-sided display TV loudspeaker box that can complete the corresponding audio output for showing content.In general, corresponding different aobvious for output
Show that the audio signal of content needs to be completed by two speakers, but two speaker assembly are complicated, while being unfavorable for TV ultrathin design.
The utility model patent proposes that a kind of new television models speaker solves the problems, such as this.
Utility model content
The purpose of the use of the new type is: needing two for the face double-sided display TV A and the face B output different audio signals
The problem of different loudspeakers, proposes a kind of two-way TV loudspeaker box spoken in front and back.By by traditional tv speaker of voice box list
Become the TV loudspeaker box of front and back bidirectional output different audio signals to the mode spoken, structure is simple.
To achieve the goals above, the utility model uses following technical scheme:
A kind of two-way TV loudspeaker box spoken in front and back, including shell, two loudspeakers, loudspeaker magnetic cylinder and audio signal are defeated
Enter line, be equipped with separate cavities in the shell, shell is divided into ante-chamber and back cavity by the separate cavities, and two loudspeakers are respectively symmetrically
It is arranged in ante-chamber and back cavity, and the cone of two loudspeakers is arranged outward, two loudspeakers respectively correspond on opposite side
Be equipped with loudspeaker magnetic cylinder, audio signal input line is corresponding to be connected on two-loudspeaker magnetic cylinder.
The utility model plays the work of isolation ante-chamber and the loudspeaker magnetic cylinder in back cavity by the way that separate cavities are arranged in shell
With the vibration both prevented has an impact.Corresponding be connected on two-loudspeaker magnetic cylinder of audio signal input line is used
In pushing magnetic cylinder vibration sounding, for converting voice signal for audio electrical signal.The audio-frequency electric of two loudspeakers of the input
Signal should input former and later two loudspeakings according to the content of double-sided display with the audio signal of corresponding ipsilateral display content synchronization
Device audio electrical signal can be different be also possible to it is identical.
Further, the quadrangle of the shell should be equipped with for installation into the mounting hole in TV.By mounting hole, so that
The utility model is easy to operate in being installed to TV.
Further, the soft rubber ring of shock-absorbing function is equipped in the mounting hole.It avoids by speaker operation generation
Vibration causes the abnormal sound of shell.
Further, it is pasted with EVA shock absorption strip respectively with rear side on front side of the shell.For avoiding in loudspeaker vibration
When, speaker is collided with TV, and to generate sound different.
The utility model has the beneficial effect that compared with prior art
Compared with prior art, the two-way TV loudspeaker box structure spoken in the front and back of the utility model is simple, simplify structure,
Technological operation, while being conducive to TV ultrathin design.It replaces needing two TVs with a two-way TV loudspeaker box spoken in front and back
The function that speaker is realized.It can be widely used in the display applied field that double-sided display etc. needs bidirectional output alternative sounds signal
Scape.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structure cross-sectional view of the utility model.
Marked in the figure: 1- mounting hole, 2- shock absorption strip, 3- loudspeaker, 4- audio signal input line, 5- loudspeaker magnetic cylinder, 6-
Connecting rod, 7- separate cavities, 8- shell.
Specific embodiment
Below with reference to embodiment, the utility model will be further described, and described embodiment is only that this is practical new
Type a part of the embodiment is not whole embodiment.Based on the embodiments of the present invention, the ordinary skill people of this field
Member's other embodiments used obtained without making creative work, belong to the protection model of the utility model
It encloses.
Embodiment 1:
As shown in Figs. 1-2, the two-way TV loudspeaker box spoken in a kind of front and back, including shell 8, two loudspeakers 3, loudspeakers 3
Magnetic cylinder and audio signal input line 4, as shown in Fig. 2, being equipped with separate cavities 7 in the shell 8, the separate cavities 7, which divide shell 8, is
Ante-chamber and back cavity, the setting of two loudspeakers 3 respectively symmetrically is in ante-chamber and back cavity, and 3 shell 8 of loudspeaker is to two loudspeakings
Device 3 plays the role of fixing and supporting.And the cone of two loudspeakers 3 is arranged outward, divides on the opposite side of two loudspeakers 3
Not corresponding to be equipped with 3 magnetic cylinder of loudspeaker, audio signal input line 4 is corresponding to be connected on 3 magnetic cylinder of two-loudspeaker.
Working principle of the utility model is: being played in isolation ante-chamber and back cavity by the way that separate cavities 7 are arranged in shell 8
