Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model It clearly and completely describes, it is clear that the embodiments are a part of the embodiments of the present invention, rather than whole implementation Example.Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without creative efforts The every other embodiment obtained, fall within the protection scope of the utility model.

As shown in Figure 1, the utility model embodiment provides a kind of screen vocal structure, comprising:

Center 10；

It is set to the printed circuit board 20 and screen assembly of 10 opposite sides of center；

Vibration device 30, the vibration device 30 are located between the printed circuit board 20 and the center 10；

Wherein, the center 10 includes the first area to fit with the vibration device 30, the first area Edge has at least one gap 11.

It should be noted that the screen assembly includes:

The display screen 41 being set on the center is provided with foam between the display screen 41 and the center 10, with Display screen 41 is avoided directly to collide with center 10；

The cover board 42 being covered on the display screen 41, the cover board 42 is display screen cover board or the cover board 42 is touching Control screen.

It should also be noted that, the vibration device 30 can be fitted on the center 10 by double-sided adhesive, in order to keep away Exempt from vibration device 30 to collide with printed circuit board 20, is provided with bubble between the vibration device 30 and printed circuit board 20 Cotton.The printed circuit board can also be mainboard.

It should also be noted that, for the ease of carrying out installation positioning to vibration device 30, described the of the center 10 The side in not set gap on one region is provided with positive stop strip 12, and the positive stop strip 12 is in printed circuit board 20 between center 10 Short transverse height be less than the vibration device 30 height.

It, can be to wherein side or more sides for remaining each side except the side of setting positive stop strip 12 on first area Turn off dividing processing.

Below by taking the first area is rectangle as an example, the specific setting in gap is described as follows respectively.

1, the first implementation in gap:

The first area is rectangle, and at least one gap includes: one be arranged at a line of the rectangle Gap.

For example, as shown in Fig. 2, the side along long side in the first area of the face vibration device 30 of center 11 is arranged one Gap 11, then when vibration device 30 vibrates, the position in gap shown in Fig. 2, vibration can not be transmitted, such vibration device 30 vibration cannot drive the center of the gap other side to vibrate, it is possible to reduce the sound wave in one direction of center reduces frequency response paddy Appearance probability.

It should be noted that the gap can also be arranged in the first area of 11 face vibration device 30 of center along rectangle The side of short side.

2, second of implementation in gap:

The first area is rectangle, and at least one gap includes: opposite two side for being set to the rectangle Two gaps.

For example, as shown in figure 3, the first area of the face vibration device 30 of center 11 along rectangle short side it is opposite two A gap 11 is respectively set in side, then when vibration device 30 vibrates, the position in gap shown in Fig. 3, vibration can not be transmitted, The vibration of vibration device 30 in this way cannot drive the center of the gap other side to vibrate, it is possible to reduce the sound of center both direction Wave reduces the appearance probability of frequency response paddy.

It should be noted that the gap can also be arranged in the first area of 11 face vibration device 30 of center along rectangle The opposite two sides of long side.

3, the third implementation in gap:

The first area is rectangle, and at least one gap includes: adjacent two side for being set to the rectangle Two gaps, and two gaps are connected.

Such mode is the edge in first area along the shape of first area, and a seam is arranged on two adjacent sides The vibration of gap, such vibration device 30 cannot drive the center of the gap other side to vibrate, it is possible to reduce center both direction Sound wave reduces the probability that frequency response paddy occurs.

4, the 4th kind of implementation in gap:

The first area is rectangle, and at least one gap includes: adjacent two side for being set to the rectangle Two gaps, and two gaps are not connected to.

Such mode is the edge in first area along the shape of first area, is respectively arranged one on two adjacent sides Gap, two gaps are not connected to.

5, the 5th kind of implementation in gap:

The first area is rectangle, and at least one gap includes: three of three sides for being set to the rectangle Gap, and three gaps are connected.

For example, as shown in figure 4, the first area of the face vibration device 30 of center 11 along rectangle short side it is opposite two A gap 11 is respectively set in side, while a gap 11 is being arranged along the side of rectangle long side, and this three gaps are connected, Constitute the big gap of a bending, then when vibration device 30 vibrates, the position in gap shown in Fig. 4, vibration can not be transmitted, The vibration of vibration device 30 in this way cannot drive the center of the gap other side to vibrate, it is possible to reduce the sound in three directions of center Wave reduces the probability that frequency response paddy occurs.

It should be noted that the gap can also be arranged in the first area of 11 face vibration device 30 of center along rectangle Opposite two sides of long side and along the side of rectangle short side.

6, the 6th kind of implementation in gap:

The first area is rectangle, and at least one gap includes: three of three sides for being set to the rectangle Gap, and three gaps are not connected to mutually.

Such mode is the edge in first area along the shape of first area, is respectively arranged one on three adjacent sides Gap, and this three gaps are not connected to.

7, the 7th kind of implementation in gap:

The first area is rectangle, and at least one gap includes: three of three sides for being set to the rectangle Gap, and there are two adjacent gaps to be connected in three gaps.

Such mode is the edge in first area along the shape of first area, is respectively arranged one on three adjacent sides Gap, and wherein having two gaps is connection.

It should be noted that above-mentioned gap set-up mode and prior art frequency response compare, in 1-1.6kHz frequency response paddy position It sets, is obviously improved, therefore channel is the important channel of voice, can be obviously improved sound effect.

It should be noted that can select to be stitched using any mode according to specific demand in practical applications The setting of gap.

It should be noted that not doing the center of dividing processing, when vibration device vibration, entire center vibration will drive, Because center is larger, the phase of different location vibration is different, when passing to human ear, the sound wave from center different location, and phase phase Instead, it just will appear sound wave interference, frequency response paddy occur.And the screen vocal structure of the utility model embodiment, center has been done point Processing is cut, when vibration device vibrates, the position disconnected on center would not transmit vibration, and the direction that vibration is only connected to center passes It passs, the direction only propagated can just generate sound wave, the problem of avoiding opposite in phase, can be lacked with this to avoid frequency, guarantee The screen vocal structure can export clearly audio.

Further, the utility model embodiment also provides a kind of terminal, including above-mentioned screen vocal structure.

It should be noted that it is provided with the terminal of screen vocal structure, when user carries out audio output using the terminal, It can be sure to be able to clearly hear audio, improve the usage experience of user.

Above-described is preferred embodiments of the present invention, it should be pointed out that for the ordinary person of the art For, it can also make several improvements and retouch under the premise of not departing from principle described in the utility model, these are improved and profit It adorns also within the protection scope of the present utility model.
