Patent application number | Description | Published |
20140098982 | PORTABLE APPARATUS - A portable apparatus including a main body and a receiver is provided. The main body has a surface, an active sound hole and a passive sound hole. The active sound hole and the passive sound hole are both disposed at the surface of the main body. The receiver is disposed inside the main body and arranged for emitting a first sound wave and a second sound wave with the same amplitude and frequency but opposite transmission directions. The first sound wave is transmitted out of the main body via the active sound hole and the second sound wave is guided in the main body and transmitted out of the main body via the passive sound hole. | 04-10-2014 |
20140121796 | AUDIO PROCESSING DEVICE - An audio processing device including a main processing unit, an audio processing unit and a codec is provided. The main processing unit includes a first audio interface. The audio processing unit having a second audio interface is controlled by the main processing unit to receive an audio signal from external and process the same. The codec is coupled to the main processing unit and the audio processing unit, respectively via the first and the second audio interfaces. The codec converts the audio signal complying with the second audio interface into the audio signal complying with the first audio interface for transferring the audio signal to the main processing unit, and the main processing unit processes audio data by using the codec and the audio processing unit. | 05-01-2014 |
20140294184 | DETECTION CIRCUIT - A detection circuit is disclosed, in which the first and second pins are arranged to connect to at least one signal transduction area of the plug, such that a voltage division circuit generates first and second division voltages accordingly. A processing unit determines the signal transduction area(s) connected by the first and second pins by the first and second division voltages. When detecting that the first and second pins separately connect the microphone area and the ground area of the plug, the processing unit controls a microphone switch to connect the first pin to the microphone output node and the second pin to the ground. When detecting that the first pin and the second pin separately connect the ground area and the microphone area, the processing unit controls the microphone switch to connect the first pin to the ground and the second pin to the microphone output node. | 10-02-2014 |
20140301562 | ELECTRONIC DEVICE AND METHOD FOR SENSING HEADSET TYPE BY AUDIO SIGNAL - In a device including a headset jack having an external microphone contact, and an external microphone signal path connected to the external microphone contact, a method including detecting whether a headset plug is plugged into the headset jack and, if the headset plug is detected, selecting an audio signal received from the external microphone signal path, recording the selected audio signal, to produce a recorded audio signal, and determining if an external microphone is connected to the external microphone contact based on the recorded audio signal. | 10-09-2014 |
20150055802 | ELECTRONIC DEVICE AND CONTROL METHOD - An electronic device includes a microphone, a bias-supply device and a voice-recognition device. The bias-supply device is configured to provide a first bias voltage to serve as an operation voltage of the microphone, when the electronic device is operated in a power-saving mode, such that the microphone transforms a voice signal into a first output signal. The voice-recognition device is configured to receive the first output signal and output a control signal, when the first output signal has a predetermined signal, to enable the electronic device be operated in a normal operation mode and the bias-supply device to provide a second bias voltage that is higher than the first bias voltage to serve as the operation voltage of the microphone, such that the microphone transforms the voice signal into a second output signal and outputs the second signal to a core circuit. | 02-26-2015 |
20150055817 | Sound Box Structure - A sound box structure is disclosed. The sound box structure includes a sound box, a speaker, and a gas absorption element. The sound box includes a sound box space. A first hole is formed on one plane of the sound box, and a second hole is formed on another plane of the sound box. The speaker is mounted on the first hole. The gas absorption element is mounted on the second hole. | 02-26-2015 |
20150078565 | Dual-Diaphragm Microphone Module to Reduce Vibration Noise - A microphone module disposed in an electronic device for reducing echo noise. The microphone module includes a casing, a first diaphragm disposed in the casing, a second diaphragm disposed in the casing and a substrate disposed between the first diaphragm and the second diaphragm and joined to the casing to define a first space and a second space which are isolated and separated from each other. The first diaphragm is disposed in the first space, the second diaphragm is disposed in the second space, and the substrate is electrically connected with the first diaphragm and the second diaphragm. | 03-19-2015 |
20150110308 | HANDHELD ELECTRONIC DEVICE - A handheld electronic device including a housing, at least one speaker and a touch display module is provided. The speaker and a touch display module are assembled to the housing. A channel is formed between the touch display module and the speaker, and a first sound is generated by the speaker and transmitted in the channel. | 04-23-2015 |
