20130188802 | HEADSET WITH TWO INTERFACES - A headset includes a microphone, a speaker, two interfaces and a controller. The interfaces are adapted to transmit first and second sound signals, which are outputted by first and second devices respectively to the controller. A third sound signal outputted by the microphone is also transmitted to the controller. The controller has a router planned with sound signal paths, which enables transmittance of the third sound signal to the second device and transmittance of the first and second sound signals to the speaker simultaneously. Therefore, the user can hear the sounds from the devices at the same time and have a conversation by means of the second device. | 07-25-2013 |
20130142375 | HEADPHONE WITH ACOUSTIC MODULATOR - A headphone having a headband and two acoustic transducers disposed at two ends of the headband is disclosed. Each acoustic transducer includes a baffle plate installed with a speaker, a spacer, a vent and an acoustic modulator. The baffle plate and speaker divide the acoustic transducer into a front and a back chamber. The front chamber is configured for communicating with a user's ear. The spacer is disposed behind the speaker to divide the back chamber into a first back chamber and a second back communicated with each other. The vent is disposed in a back wall of the acoustic transducer to communicate the first back chamber with outside. The first acoustic modulator is disposed between the front and second back chambers. The headphone modulates resonance frequency at low frequency bands through the acoustic modulator. | 06-06-2013 |
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 |
