Description

Sound production screen structure and device

Technical Field

The invention relates to the technical field of screens, in particular to a sounding screen structure and a sounding screen device.

Background

Laser cinema (television) is the indispensable common household electrical appliances of modern and future family, because it adopts reflective imaging principle, has avoided the direct incidence of light to the injury that the eye brought, just as the reflection of natural scenery under the sunshine gets into people's eye comfortable, healthy, natural, and visual comfort is superior to the paper and reads 20%. The maximum coverage rate of the color gamut can reach 160% BT.709, the colors are richer and more gorgeous, the real colors can be restored, and in addition, the Fresnel passive bionic screen is matched, so that the screen is not electrified, and is free of radiation and electromagnetic radiation interference.

Because of the current technological limitation, the Fresnel screen can not be cancelled in the current laser cinema products, and the main function of the screen is to improve the image display effect by the technology of directionally controlling the direction of light reaching human eyes. The separation effect of the host computer and the screen, the placement position of the sound box and other reasons have certain sensory influence on the effect of the laser television, for example, the audience always feels that the sound is not emitted from the image, and the sound is generated from other places as if the sound is always separated from the image. If the sound is emitted from the image as in the traditional television, the sound is perceived as the sound emitted by people in the television picture, and the feeling of separating the image from the sound is not provided, so that the audience can feel more real when watching the sound. However, due to the existing design of screen structure and the display of the host and the screen, a screen which not only contains a loudspeaker but also can not influence the display effect of the screen when the loudspeaker vibrates can not be designed on the screen. Some prior patents show that the effect of screen sound production is increased by placing a loudspeaker at the back of the screen, but the problem that the screen size is increased and the appearance is affected is solved, so that the screen looks thick and hard to see, and the space occupied by the host gives people an uncomfortable feeling on the whole and cannot be matched with the high and big feeling of a laser television.

After the screen is combined with the sound, the attractiveness of the screen can not be influenced, so that the screen still looks thin, is attached to a wall and does not occupy any space, and the screen does not have any shaking influence on the screen when the sound is generated and vibrated. In order to make the screen more closely feel to the wall and thinner, the traditional wall hanging mode needs to be changed.

Chinese patent CN108006412A discloses a suspension structure using damping rubber to reduce resonance and noise, which adopts the measure of preventing resonance of screen image product when the sounding body vibrates, but cannot completely prevent the resonance of screen, because the screen does not adopt backboard material with good structural strength, but adopts a suspended cavity structure, the design of the cavity structure is designed primarily to ensure that the sounding body has certain amplitude, and open a space for amplitude, but because of the requirement of transmitting sound effect, the space requirement is larger, this generates a far distance that the screen needs to be far away from the wall, so that the screen has poor wall-attaching feeling. Meanwhile, for the safety of suspension, a firm fixing mode must be adopted for the screen, and the firm fixing mode cannot necessarily block the transmission path of sound, that is, no matter what damping mode is adopted, resonance of the sound-producing body on an image product of the screen cannot be completely avoided, and the image cannot be influenced by vibration emitted by the sound-producing body.

In chinese patent CN110035364A, a vibration plate, an exciter and a vibration transmitter are used, although this structure can transmit the sound transmitted by vibration, but also has the problem of the resonance of the sound on the image, and this solution may be still usable for a small-sized screen, but for a 100-inch screen, the image shake due to the resonance is not solved. This also ultimately results in the solution not being applicable in the field of large-size screens. Namely, the scheme can only be applied to small-sized parts, such as mobile phones and PAD products, and cannot be applied to large-screen laser television products due to large occupied space.

The sounding screen disclosed in the chinese patent CN204425649U drives the screen to vibrate and sound, and this way is used for small screens, such as mobile phone products, PAD products, etc., and no products sold by this product are seen, so it is not suitable for large-size laser television screen products.

In conclusion, the structure for the laser film (television) product is good in wall pasting feeling, simple in structure, simple to assemble and low in cost, and the structure for the laser film (television) product is not available, so that the requirement of a consumer on the aspect cannot be met.
