Example embodiments disclosed herein relate to orientation-aware surround sound playback. A method for processing audio on an electronic device that includes a plurality of loudspeakers is disclosed, the loudspeakers arranged in more than one dimension of the electronic device. The method includes, responsive to receipt of a plurality of received audio streams, generating a rendering component associated with the plurality of received audio streams, determining an orientation dependent component of the rendering component, processing the rendering component by updating the orientation dependent component according to an orientation of the loudspeakers and dispatching the received audio streams to the plurality of loudspeakers for playback based on the processed rendering component. Corresponding system and computer program products are also disclosed.

A technique is disclosed for automatic switching of a mobile device between a videoconference operating mode and a teleconference operating mode, where the automatic switching is based on a detected functional use and current position of the device in relation to a user of the device. In at least some embodiments, the disclosed technology includes a video-audio switching system that works in coordination with a sensor mechanism associated with the device to enable the automatic switching. The technology disclosed herein enables the user to carry out a conversation via the device (i.e., conference session) without interruption when transitioning between different settings, (e.g., using the device while sitting at an office to using it while on-the-go to an appointment).

Embodiments disclosed herein generally relate to method or apparatus that can automatically control the delivery of an audio output to a user. In some embodiments, an audio device that can automatically deliver, halt and/or modify an audio signal based on an impedance measurement made by electrical elements in a headphone or between electrical elements in both headphones of the audio device.

Provided is a selection device including an acquisition section for acquiring digital selection signals, and an output section for outputting selection signals to respective unit cells, each unit cell capable of being commanded to output the value zero. The selection device is characterized in that: each selection signal is for commanding the unit cell to output a value corresponding to that selection signal; the sum of the values to be output as commanded by the respective selection signals, which are output to the respective unit cells, is a value determined in association with the digital selection signal; and if the output corresponding to the digital selection signal is the value zero, then selection signals each commanding to output a non-zero value (N) are output to some of the unit cells.

A display apparatus, control method, and system are provided. The display apparatus includes a display; one or more loudspeakers; a signal processor configured to process an image signal so that an image may be displayed on the display and sound may be output from the loudspeaker; a communication interface configured to communicate with one or more external display apparatuses; and a controller configured to transmit sound processed by the signal processor to the one or more loudspeakers in accordance with a preset output designation state, determine a divided and displayed state of an image with respect to the display apparatus and the one or more external display apparatuses, and adjust the output designation state of the sound with respect to the one or more loudspeakers based on the determination.

A user device determines whether a device connected to its headset jack is an audio accessory device. If the device connected to the headset jack is an audio accessory, the user device connects one or more pins of the headset jack to an audio codec. If the device plugged into the headset jack is not an audio accessory device, the user device connects one or more pins of the headset jack to alternate circuitry. The user device then determines, through the alternate circuitry, an electrical operating parameter requirement of the accessory device, and provides, from the alternate circuitry, the required operating parameter to the accessory device through the headset jack. The alternate circuitry may include an adjustable voltage regulator and/or an adjustable current regulator and the required operating parameter may be one or more of a voltage supply and a current supply.

An earset, according to various examples, comprises: an electronic device connection unit having a microphone terminal connected to a microphone of the earset, an audio ground terminal connected to an audio ground of the earset, a right speaker terminal, and a left speaker terminal; and a switch for allowing, according to a voltage of the microphone terminal, a right speaker and a left speaker of the earset to be mutually connected with one of the right speaker terminal and the left speaker terminal, and the other one of the right speaker terminal and the left speaker terminal to be connected with a shield ground of the earset. Other examples are possible.

An audio processing device and an audio processing method are provided. The audio processing device includes a first controller configured to initialize the audio processing device; and a second controller configured to connect the audio processing device and an audio output device while the first controller initializes the audio processing device, and to transmit a message reporting completion of the connection of the audio processing device and the audio output device to the first controller, wherein the first controller is configured to start an operation of outputting audio to the audio output device in response to the message reporting the completion of the connection from the second controller.

An electronic device may comprise audio processing circuitry and a universal serial bus (USB) connector having a first contact and a second contact. In a first mode of operation, the audio processing circuitry is configured to output one or more audio signals carrying music and/or voice via the first contact and the second contact. In a second mode of operation, the audio processing circuitry is configured to output a signal for delivering supply current via the first contact and the second contact. While the electronic device is in the first mode of operation, a gain and/or volume limit of the audio processing circuitry may be set to a first level, and while the electronic device is in the second mode of operation, the gain and/or volume limit of the audio processing circuitry may be set to a second level that is higher than the first level.

An electronic device including a housing, at least one first sound output unit, a connecting module and a second sound output unit is provided. The first sound output unit is located inside or outside the housing. The connecting module is disposed on the housing. The connecting module includes a base and a sensing component. The base has a slot. The sensing component is disposed on the base as corresponding to the slot. The second sound output unit at least includes a plug. The plug is detachably assembled to the slot and is adapted to rotate relative to the base along an axis line, so as to determine whether the plug is sensed by the sensing component to make the electronic device switch between a first sound output mode and a second sound output mode.
