Embodiment 1

[0060] Figure 4 It is the exploded view of the structure of embodiment 1. Example 1 includes:

[0061] 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 .

[0062] A conductive thin film 2 is coated on the vibrating thin film 1 . The conductive film 2 is a f...

Embodiment 2

[0067] Figure 6 It is the exploded view of the structure of embodiment 2. Example 2 includes:

[0068] 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 more ...

Embodiment 3

[0073] Figure 7 It is the exploded view of the structure of embodiment 3, and embodiment 3 comprises:

[0074] 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.

[0075] 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.

[0076] A plurality of conductive terminals 5 are attached to the conductive film 2 and connected to the speaker drive circuit;

[0077] Two layers of insulating layers 11 are respectively attached to the outer sides of th...

Abstract

The present invention discloses a curved sound player having a projection display function. The curved sound player having the projection display function comprises a curved display and a projection device, and also comprises a film speaker attached onto the curved display, wherein the film speaker comprises at least one sounding film, at least one conductive film, at least one insulating layer, and at least two conductive terminals; the at least one conductive film is coated on the at least one sounding film; the at least one conductive film is made from a nano-wire material; the at least one insulating layer is attached onto the at least one conductive film; the at least one insulating layer and/or a tone quality improving layer comprise(s) a plurality of groups of micro machining structures; the at least two conductive terminals are attached onto the at least one conductive film and are connected with a speaker driving circuit. According to the present invention, the film speaker and the curved projection display are combined, and the film speaker is attached onto the surface of the curved projection display; as the film speaker is transparent, the content displayed by the curved projection display is not influenced, and the display can play sound simultaneously while displaying videos or images, and therefore, the practicability of the display is enhanced, and the intelligence is relatively high.

Description

technical field [0001] The invention relates to a sound player, in particular to a curved surface sound player with projection and display functions. Background technique [0002] In the prior art, the sound player is only used for playing sound, and the function is relatively single, but the sound player in the prior art is a traditional audio system, whether it is an electric type (that is, a moving coil type), an electrostatic type ( That is, capacitive), electromagnetic (reed), or piezoelectric (crystal), they all have common shortcomings, that is, large volume, bulky appearance, constant movement, many production processes, and relatively high cost. High, so it is not suitable for further transformation. [0003] In the prior art, the concept of thin-film audio has emerged, and thin-film audio is suitable for combining with other electronic products because of its lightness, changeable shape, and transparency. However, most of the thin-film speakers in the prior art h...
