| 20090022342 | DIGITAL DECODER BOX WITH MULTI-CHANNEL AUDIO SOURCE FORMAT INDENTIFICATION FUNCTION - A digital decoder box is introduced for processing multiple-channel digital audio sources. The digital decoder box can detect formats of audio sources and perform different decoding processes, and output the audio sources to an earphone with 5.1 channel speakers. When a 5.1 channel audio source is received, the digital decoder box decodes the audio source and outputs the audio source to the 5.1-channel earphone. Three sets of audio signals are outputs including front stereo signals, rear stereo signals, center channel signal, and sub woofer signal. When a two channel audio source is received, the amplified audio signals from the digital decoder box are output to at least two sets of speakers within the 5.1-channel earphone. By the various speaker combinations within the 5.1-channel earphone, sound effects of separated sound fields may be generated. A two channel stereo audio source may then have different sound effects. | 01-22-2009 |
| 20100054508 | MULTIPLE-CHANNEL DIGITAL SOUND FIELD WIRELESS EARPHONE DEVICE - A digital wireless earphone device with stereo or multiple-channel sound effect automatic detection and switching functions is provided. The multiple-channel digital wireless earphone device uses a signal processing and transmitting device to decode multiple-channel signal sources. After the decoding is completed, the multiple-channel signal sources are concurrently transmitted to a wireless earphone end through a radio. After being directly digital-to-analog converted and amplified, the multiple-channel signals are connected to a plurality of speakers to generate a multiple-channel surround sound field. The wireless earphone at a receiving end further has an automatic detection function for detecting a 6CH or 2CH sound source and automatically selects an earphone playing mode accordingly. | 03-04-2010 |

| 20080247588 | MULTIPLE CHANNEL EARPHONE AND STRUCTURE THEREOF - A multiple channel earphone is provided, which includes a chamber main body and a main chamber support located in the chamber main body. A front field mixing chamber, a main chamber, and a back chamber are formed in the chamber main body. The main speaker is located on the main chamber support or a partition board, a sub-speaker is disposed on a protruding portion of the chamber main body, and the back chamber is formed between the sub-speaker and the main chamber support or the partition board. In an embodiment, the multiple channel earphone structure further includes at least one or more pairs of chamber extension tubes disposed outside the chamber main body. According to the length of each chamber extension tube and the space in the chamber main body, a composite sound field characteristic generated in the earphone structure is adjusted and output by the multiple channel earphone. | 10-09-2008 |
| 20090041290 | EARPHONE SPEAKER WITH ESD PROTECTION - An earphone speaker including a conductive housing, a micro speaker module, and a circuit board is provided. The conductive housing has a holding space. The micro speaker module is disposed in the holding space. The circuit board is disposed outside the conductive housing, and has a first surface facing towards the conductive housing and a second surface corresponding to the first surface. A positive terminal and a negative terminal are disposed on the second surface and electrically connected to the micro speaker module. A conductive material layer is disposed on the first surface and electrically connected to the negative terminal, and the conductive material layer is directly contacted with the conductive housing. | 02-12-2009 |
| 20090047905 | STEREO BLUETOOTH HEADSET - A stereo bluetooth headset including a bluetooth transceiver, at least one inter-speaker, a microphone and an audio output port is provided. The bluetooth transceiver is used for transceiving signals with an electronic device in a wireless mode. The inter-speaker is electrically connected to the bluetooth transceiver for broadcasting audio signals received from the electronic device. The microphone is electrically connected to the bluetooth transceiver. The audio output port is electrically connected to the bluetooth transceiver and suitable for connecting to an audio input port of an outer-speaker through a connecting cable, so as to transmit stereo audio signals received from the electronic device to the outer-speaker through the connecting cable for broadcasting. | 02-19-2009 |
| 20090060238 | EARPHONE STRUCTURE WITH A COMPOSITE SOUND FIELD - An earphone structure including one or more composite chambers is described. Each of the composite chambers includes sub-speakers. The sounds generated by these sub-speakers are uniformly distributed in the composite chamber and a composite sound field is generated by these sub-speakers. The sound field generated by each of these sub-speakers can be adjusted by re-locating the position of the sub-speaker, for example, by re-locating the sub-speaker, or by re-locating the sub-speaker in different angles, to generate the composite sound field. The sound field generated by the main speaker and the composite sound field generated by these sub-speakers can form a spatial sound with very good quality. By using of its physical characteristics of locations of these sub-speakers, the sound generated by the earphone has an uniformly diffusion sound pressure and a surround effect, which allows a user of the earphone to enjoy a sound field similar to that in a theater. | 03-05-2009 |

| 20090232340 | EARPHONE STRUCTURE CAPABLE OF ADJUSTING VENTILATION OF CHAMBER THEREIN - An earphone structure which allows adjusting ventilation of a chamber inside is provided. A plurality of holes is formed on a main body of the earphone structure and ventilation materials are disposed on the ventilation holes as a ventilation medium between the chamber in the main body and an external environment. A sound field generated in the chamber is changed through the change of the materials, which makes the sound field close to the natural tone. The adjustment of the ventilation is mainly based on the fact that sound has different frequency response effects on different materials in the transmission environment, thus achieving the effect of changing the sound field. For example, the adjustment of the ventilation can be achieved by filling different materials in the chamber. Further, partition part of the chamber can also use the frequency response of the sound of materials with different hardness. | 09-17-2009 |
