This abstract first appeared for US patent application 18561760 titled 'DIAPHRAGM FOR SOUND GENERATING DEVICES AND PREPARATION METHOD THEREOF, AND SOUND GENERATING DEVICE

The present invention is about a diaphragm for sound generating devices made of a thermoplastic polyester elastomer film, and a method for preparing it, as well as a sound generating device. The diaphragm is composed of a single layer of the thermoplastic polyester elastomer film, with specific thickness and loss factor characteristics.

* The diaphragm is made of a thermoplastic polyester elastomer film with a unique composition, providing improved resistance to high temperatures and chemicals.
* The material used in the diaphragm enhances sensitivity and maintains essential properties like stiffness, resilience, and damping required for vibration.
* The thermoplastic polyester elastomer film is formed by copolymerization of a polyester hard segment and an aliphatic polycarbonate soft segment, ensuring a balance of properties.

Potential Applications:
- Sound generating devices
- Speakers
- Headphones
- Microphones

Problems Solved:
- Poor resistances to high temperatures and chemicals in existing thermoplastic elastomers
- Lack of sensitivity in sound generating device diaphragms
- Inadequate balance of stiffness, resilience, and damping in traditional materials

==Original Abstract Submitted==

The present invention relates to a diaphragm for sound generating devices and a preparation method thereof, and a sound generating device. The diaphragm for sound generating devices comprises only one layer of a thermoplastic polyester elastomer film, wherein the thermoplastic polyester elastomer is formed by copolymerization of a polyester hard segment which is prepared by reacting an aromatic dicarboxylic acid with a dihydric alcohol and a soft segment containing an aliphatic polycarbonate, and the diaphragm has a thickness of 10-200 □m, and a loss factor of 0.1-0.3 at a temperature of 23° C. The thermoplastic polyester elastomer used for the diaphragm of the present invention is composed of the polyester hard segment and the aliphatic polycarbonate soft segment, and such material not only solves the problem that the existing thermoplastic elastomers have poor resistances to high temperatures and chemicals, but also improves sensitivity, and can also well achieve the basic properties such as stiffness, resilience and damping required by vibration of the diaphragm.
