20120063607 | MOBILE ELECTRONIC DEVICE AND SOUND PLAYBACK METHOD THEREOF - A mobile electronic device and a sound playback method thereof are provided. The mobile electronic device includes a sensor, a speaker, and a controller coupled to the sensor and the speaker. The sensor detects whether the speaker is blocked or not. When the speaker is blocked, the controller multiplies a sound signal by a transfer function and then outputs the multiplied sound signal. The speaker plays the sound signal outputted by the controller. The transfer function changes the direction in which the speaker plays the sound signal. | 03-15-2012 |
20120219169 | METHOD AND APPARATUS FOR ADJUSTING SOUND QUALITY - An electronic apparatus and a method for providing a sound system of the electronic apparatus are provided herein. The electronic apparatus has a housing, a speaker and a bracket. The housing has a space and a channel, which is coupled to the space. The speaker is placed in the space. The bracket has a first end coupled to the channel and is movable relative to the housing. A sound mode of the electronic apparatus may be switched from a first mode to a second mode by positioning a second end of the bracket from a first position in the channel to a second position away from the channel. | 08-30-2012 |
20130117017 | ELECTRICAL APPARATUS AND VOICE SIGNALS RECEIVING METHOD THEREOF - An electrical apparatus a voice signal receiving method thereof are disclosed. The electrical apparatus includes a plurality of voice receivers, a voice activity detector, a voice channel switch and a noise eliminator. The voice receivers are used to receive the voice signals. The voice activity detector receives and detects the voice signals, and obtains a main voice signal from the voice signals. The voice channel switch transports the main voice signal to a voice transporting channel and transports a plurality of other voice signals of the voice signals other than the main voice signal to a noise transporting channel according to a detecting result of the voice activity detector. The noise eliminator reduces the noise in the main voice according to the voice signals from the noise transporting channel. | 05-09-2013 |
20130251158 | AUDIO SIGNAL MEASUREMENT METHOD FOR SPEAKER AND ELECTRONIC APPARATUS HAVING THE SPEAKER - An audio signal measurement method for a speaker and an electronic apparatus having the speaker are provided. The electronic apparatus further has a processing circuit and a power amplifier. The processing circuit is coupled to the speaker and configured to execute a time domain to frequency domain transform according to a voltage value of an audio signal and a current value of current feedback from the speaker so as to obtain a frequency response curve. The power amplifier is coupled to the speaker and configured to drive the speaker according the voltage value of the audio signal. The processing circuit is capable of determining whether the frequency response curve is located within a predetermined area such that the processing circuit generates a signal when the frequency response curve is located out of the predetermined area. Thereby, the electronic apparatus may measure its transducer distortion and acoustic box leakage. | 09-26-2013 |

20140158732 | CAR HOLDER - A car holder adopted to be assembled with a mobile apparatus is provided. The mobile apparatus has a loudspeaker located at a back portion thereof, and the loudspeaker has a sound-output surface. The car holder includes a fixing module and a supporting base. The fixing module is adopted to be assembled within a car, and the supporting base is connected to the fixing module. The supporting base has a leaning surface and a full opening indented therein. When the mobile apparatus is assembled to the supporting base, the back portion leans against the leaning surface, and a portion of the full opening is covered by the mobile apparatus. The sound-output surface of the loudspeaker communicates with the full opening, and sound wave outputted by the sound-output surface, after being reflected by the full opening, is transmitted from the full opening in a direction far away from the leaning surface. | 06-12-2014 |
20140219475 | APPARATUS AND METHOD OF MULTI-SENSOR SOUND RECORDING - An apparatus and a method for sound recording are provided. The apparatus stores an equalizer and includes a housing, a microphone, and a processor. The microphone includes a plurality of sensors and receives a sound signal through an acoustical resonator in the housing. The microphone generates a plurality of electronic signals in response to the sound signal. The equalizer generates a plurality of equalized signals according to the electronic signals. The processor generates an output signal according to the equalized signals. The equalizer compensates the gain margin and the phase margin caused by the sound signal passing through the acoustical resonator in order to prevent the output signal from being affected by resonance of the sound signal in the acoustical resonator. | 08-07-2014 |
