| 20110305360 | EARPHONE DEVICE WITH A FUNCION OF SOUND QUALITY REGULATION AND REGULATING METHOD THEREOF - An earphone device with a function of sound quality regulation is provided. The earphone includes a housing, a cover, a speaker and a regulating device. The housing has an accommodating space for receiving the speaker and a plurality of regulating holes for connecting the accommodating space to the outside. One end of the regulating device is fixed on the cover. A blocking portion, which is disposed on the other end of the regulating device and extends into the accommodating space, can partially or completely block the regulating holes when the cover is turned, thereby regulating the leakage between the accommodating space and the outside to achieve different output sound quality. | 12-15-2011 |
| 20100236861 | DIAPHRAGM OF ELECTRO-ACOUSTIC TRANSDUCER - A diaphragm of an electro-acoustic transducer is provided. The diaphragm of the electro-acoustic transducer includes a central portion and a peripheral portion. The rigidity of the central portion is greater than the peripheral portion, such that the diaphragm has different rigidity characteristics, and thus gets better high-frequency performance and better sensitivity. | 09-23-2010 |
| 20100075539 | ELECTRICAL CONNECTOR AND THE TERMINAL THEREOF - An electrical connector is disclosed, which is configured with an insulating frame for carrying a speaker while arranging terminals at two sides of the insulating frame. Each of the terminals further comprises a vertical-extending fixing part for holding securely on the insulating frame, and a movable part connected to the fixing part while parallel-extending from the same. With the aforesaid structure, as the terminals only occupy a small space available on the insulating frame comparing with those conventional connectors, the electrical connector of the invention is able to carry a speaker with larger magnet so that the aforesaid electrical connector is preferred as it can, in a way, enhance the electrical performance of the speaker. | 03-25-2010 |
| 20090196454 | EARPHONE SET - An earphone set includes a main device having a digital signal processor, and an earplug has an external microphone and a speaker electrically connected with the digital signal processor respectively. The external microphone converts an external sound wave into an electronic signal and transmits the electronic signal to the digital signal processor for processing. The speaker converts the electronic signal processed by the digital signal processor into a sound wave for output. | 08-06-2009 |
| 20090196443 | WIRELESS EARPHONE SYSTEM WITH HEARING AID FUNCTION - A wireless earphone system includes a main device and two ear-hang devices. The main device having a digital signal processor, a server-end wireless transmitting module and a server-end wireless receiving module electrically connected with the digital signal processor respectively. Each ear-hang device has a microphone, a speaker, a client-end wireless transmitting module electrically connected to the microphone and a client-end wireless receiving module electrically connected to the speaker. The microphone collects an external sound wave and converts the external sound wave into an electronic signal for transmission to the digital signal processor by the client-end wireless transmitting module and the server-end wireless receiving module, and the processed electronic signal is transmitted by the server-end wireless transmitting module and the client-end wireless receiving module to the microphone for converting into a sound wave. | 08-06-2009 |
