Embodiment 1

[0063] Figure 4 It is the exploded view of the structure of embodiment 1. Example 1 includes:

[0064] A sound emitting film is composed of a vibrating film 1 with the characteristics of dipole moment charge distribution and a sound quality improving layer 3 attached on the vibrating film 1 . In this embodiment, hollow air cells with a diameter of 10 mm are arranged on the sound quality improving layer 3 as microfabricated structures, that is, in this embodiment, the microfabricated structures are a plurality of hollow air cells with the same shape. Figure 5 A schematic diagram of a single hollow bubble. The sound quality improvement layer 3 of embodiment 1 is a plurality of Figure 5 The bubble structures shown are arranged regularly, the bubble structures 6 contain air, and edge structures 7 are arranged around each bubble structure to seal the bubble structures 6 .

[0065] A conductive thin film 2 is coated on the vibrating thin film 1 . The conductive film 2 is a f...

Embodiment 2

[0070] Figure 6 It is the exploded view of the structure of embodiment 2. Example 2 includes:

[0071] A sounding film, the sounding film in embodiment 2 is a thin film structure, the sound quality improving layer 3 and the vibrating film 1 are connected together in a checkerboard grid shape, and the structure is like a chessboard. . In this way, the vibration range of the vibrating membrane 1 can still reach the entire area of ​​the membrane loudspeaker, but the material usage of the vibrating membrane 1 is greatly reduced, which saves costs. And because the vibrating membrane 1 and the sound quality improving layer 3 are arranged at intervals, the sound quality improving layer 3 is made of a material different from the material of the vibrating membrane 1, and the vibration frequency of the vibrating membrane 1 is different, and the vibrating membrane 1 and the sound quality improving layer 3 are mutually Supplement makes the sound from the entire sound-producing film mo...

Embodiment 3

[0076] Figure 7 It is the exploded view of the structure of embodiment 3, and embodiment 3 comprises:

[0077] A sounding film, the sounding film includes two layers of vibrating film 1 with the characteristics of dipole moment charge distribution, and a layer of sound quality improving layer 3 sandwiched between the two layers of vibrating film 1 . In this embodiment, the sound quality improving layer 3 is made of plastic.

[0078] The two layers of conductive films 2 are respectively coated on the two layers of vibrating films 1 . In this embodiment, the conductive film 2 is a film made of nano-metal wire material. In this embodiment, nano-copper wires are used as the conductive film 2 and coated on the vibrating film 1 by a spray film-forming method.

[0079] A plurality of conductive terminals 5 are attached to the conductive film 2 and connected to the speaker drive circuit;

[0080] Two layers of insulating layers 11 are respectively attached to the outer sides of th...

Abstract

The invention discloses a display with a sound function. The display comprises a curved display and a projection device. The display further comprises a film speaker attached onto the curved display. The film speaker comprises at least one sounding film, at least one conductive film, at least one insulated layer, and at least two conductive terminals. The at least one conductive film is applied to the sounding film and made of a nano-metal wire material. The at least one insulated layer is attached onto the conductive film. The insulated layer and/or a tone quality improvement layer comprise/comprises multiple groups of micro-machined structures. The at least two conductive terminals are attached onto the conductive films and connected with a speaker driving circuit. According to the display, the film speaker is combined with the curved projection display, the film speaker is attached onto the surface of the curved projection display, and the film speaker is transparent and does not influence the content displayed by the curved projection display, so that a sound can be played when the display displays a video or an image, the practicality of the display is improved, and the display is more intelligent.

Description

technical field [0001] The invention relates to a display, in particular to a display with sound function. Background technique [0002] With the popularity of electronic products such as computers, displays have become an integral part of electronic products that are indispensable to modern people's lives. Existing displays, no matter computer monitors or television monitors, only have a simple display function. If you want to play audio or dub video, you need to connect an external audio or set an audio in the cabinet. [0003] In the prior art, the traditional speakers externally connected to the display, whether electric (ie moving coil), electrostatic (ie capacitive), electromagnetic (ie reed), or piezoelectric (ie crystal) They all have common shortcomings, that is, large volume, cumbersome appearance, constant movement, many production processes, and high cost. This has hindered the further development of TV sets and computers, making TV sets and computers necessary...
