Problems solved by technology

[0020] However, due to the extremely small displacement of the diaphragm of the electrostatic electro-acoustic device, the motion is almost linear, even if the unequal electrostatic force is used to cause equal displacement of the entire area of ​​the diaphragm, the sound quality cannot be significantly improved.
Moreover, the signal-driven amplifying device of this traditional technology is complicated, expensive, bulky, and power-consuming, and is not suitable for applications that require tiny speakers such as earphones, hearing aids, and mobile phones.
In addition, the application of this traditional technology still requires a hard hanging edge to fix the diaphragm, and the perforated backplane is also hard, which cannot be made into a flexible device.
In this way, there are also deficiencies in the aforementioned patents, so that they cannot be applied to products developed using flexible electronic technology
[0021] Due to the limitation of the above-mentioned traditional technology in the principle of pronunciation, it is necessary to fix the hanging edge to tighten the diaphragm, which does not have a flexible function, and has a large volume, complex structure, high cost, energy consumption, and is not conducive to mass production. Therefore, how to effectively solve the problems existing in the previous technology has become an urgent problem to be overcome in the industry

[0072] 1 to 6 are drawings of the first embodiment of the flexible loudspeaker and its manufacturing method according to the present invention.

[0073] Referring to FIG. 1 , a schematic exploded view of the flexible speaker of the present invention is shown. The flexible speaker 1 shown in the figure includes a first diaphragm 11 , a second diaphragm 13 , a first electrode 15 , a second electrode 16 , and The first flexible driving member 17 and the second flexible driving member 19 .

[0074] As shown in FIG. 1 , the first diaphragm 11 and the second diaphragm 13 have first surfaces 111 , 131 and second surfaces 113 , 133 , respectively. In this embodiment, the first vibrating film 11 and the second vibrating film 13 can be selected as electret piezoelectric vibrators, such as electret piezoelectric vibrators that can retain static charges for a long time after the dielectric material is electrized. diaphragm, and the first diaphragm 11 and the second diaphragm 13 can be di...

[0095] FIG. 7 is a drawing of a second embodiment of a flexible speaker and a manufacturing method thereof according to the present invention. Wherein, the same or similar components as in the foregoing embodiments are represented by the same or similar component symbols, and the detailed description is omitted to make the description of the present case more clear and easy to understand.

[0096] The biggest difference between the second embodiment and the first embodiment is that the first flexible driving member and the second flexible driving member in the first embodiment can be composed of, for example, a flexible conductive perforated plate and a spacer. In the example, the first flexible driving member and the second flexible driving member can be, for example, conductive metal sheets. At the same time, as shown in FIG. 7 , in the manufacturing process of this embodiment, an electrode is formed on the first surface of one of the first and second diaphragms in step S2 ′...

Abstract

This invention relates to one flexible microphone and its process method, which forms sound to same direction with flexible piezoelectricity materials property by flexible driver parts, vibration film, and vibration electrode to overcome traditional technique defaults.

Description

technical field [0001] The invention relates to a sound generating device, in particular to a flexible loudspeaker and a manufacturing method thereof. Background technique [0002] As the industry pursues the development trend of light, thin, short, and multi-functional products, in order to improve the market competitiveness of products, the industry hopes to apply advanced technology to develop and manufacture products. [0003] In the case of a loudspeaker, the sounding principle of the loudspeaker is to vibrate the diaphragm through the generation of electrical signals to generate sound. Consumer electronics such as mobile phones, personal digital assistants (PDAs), and digital cameras, among which flat-panel displays are currently being developed using flexible electronics technology; that is, through flexible plastic Or flexible electronic components such as thin metal substrates to produce related electronic products. Because the products manufactured by the applica...
