An information processing apparatus according to an embodiment of the present technology includes a detection unit; a first acquisition unit; a second acquisition unit; and a generation unit. The detection unit detects a reproduction apparatus. The first acquisition unit acquires a reproduction mode of the detected reproduction apparatus. The second acquisition unit acquires history information, the history information including a reproduction apparatus selected in a past and a reproduction mode of the reproduction apparatus when the reproduction apparatus has been selected in the past. The generation unit generates an operation image, the operation image including detection information and the acquired history information, the detection information including the detected reproduction apparatus and a reproduction mode of the reproduction apparatus when the reproduction apparatus has been detected.

A composite headphone is provided. The composite headphone includes a wireless Bluetooth headphone and a wired headset. The wireless Bluetooth headphone is detachably arranged on the wired headset. When the wireless Bluetooth headphone separates from the wired headset, the wireless Bluetooth headphone operates independently and the wired headset operates independently. When the wireless Bluetooth headphone is arranged on the wired headset and a composite event is triggered, the wireless Bluetooth headphone cooperates with the wired headset, so that the wired headset operates as a wireless Bluetooth headphone. When the wireless Bluetooth headphone is arranged on the wired headset and no composite event is triggered, the wired headset charges the wireless Bluetooth headphone.

Disclosed is a wireless headset role switching method, relating to the technical field of portable listening devices, wherein a main wireless headset is a headset currently establishing a connection with a terminal, and a slave wireless headset is a headset not currently establishing a connection with the terminal. The method includes: when receiving an in-place instruction, a main wireless headset sending connection information of the main wireless headset and a terminal to a slave wireless headset, so that the slave wireless headset initiates a connection request to the terminal according to the connection information and establishes a connection with the terminal, thereby completing wireless headset role switching. Also disclosed are a wireless headset, a wireless connection device role switching method, a TWS headset and a computer-readable storage medium, having those beneficial effects.

Various embodiments provide an electronic device and a method, the device comprising: an audio module; a display; a connection terminal connected to earphones; a communication interface; and a processor electrically connected to the audio module, the display, the connection terminal, or the communication interface, wherein the processor is set to display execution screens associated with a first application and a second application through a multi-window, respectively, and output an audio signal corresponding to the first application and an audio signal corresponding to the second application to a left terminal or a right terminal of the earphones separately based on a window position corresponding to each execution screen. In addition, other embodiments are also possible.

Disclosed are a method, an apparatus and an electronic device for controlling audio playback of multiple loudspeakers, wherein the method comprises: determining the location information of each speaker and voice signals issued by each speaker; determining the area where each speaker is located according to the location information of each speaker; determining voice instruction corresponding to each voice signal; and controlling the multiple loudspeakers to play the audio indicated by the corresponding voice instruction respectively for the area where the speaker of each voice instruction is located. According to the method and apparatus and/or the electronic device in an embodiment of the present disclosure, different audios can be played for different areas in a preset space.

Provided are a terminal, a terminal peripheral, a signal transmission system, and a signal sending and receiving method. The terminal includes: a first audio module, which is connected to the USB receptacle in a terminal through an I2S bus channel and is configured to send a signal to be sent to a USB receptacle; the USB receptacle is configured to provide a physical connection interface between the terminal and a terminal peripheral.

To enable listening with a desired number of channels at a lower cost and without wasting resources. According to the present invention, a multi-channel digital audio signal is processed through the cooperation of a plurality of AV amplifier devices. One AV amplifier device 1 serves as a master, and distributes the audio channels to be processed to the other AV amplifier devices 1 including the own device 1, and determines, on the basis of the signal processing time of each AV amplifier device 1, the output delay time of each AV amplifier device 1 such that the output timings of the analog audio signals of all AV amplifier devices 1 match each other. Then, the AV amplifier device 1 decodes the input digital audio signal into an analog audio signal for an audio channel distributed to the own device 1 by the master, and delays and outputs the decoded analog audio signal by the output delay time of the own device 1 determined by the master.

Provided are a content playback program, a content playback device, a content playback method, and a content playback system capable of playing back sounds closer to those intended by game creators by selecting sound files, as well as settings of an equalizer, a mixer, etc., according to a sound output destination. A content playback processing unit, when started and when returned from a background state to a foreground state, checks an audio device and performs setting appropriate for the audio device. In addition, when the audio device is changed in the foreground state, the content playback processing unit also performs setting appropriate for the audio device changed to. This makes it possible to play back sounds closer to those intended by game creators according to the audio device.

At least a system or a method is provided for remote delivery or collection of a device such as an audio collection device. For example, a device comprising an aperture collection and retrieval pin is provided. An apparatus is provided having an aperture receiver, an aperture drive gear and a drive motor. The drive motor is configured to drive the aperture drive gear to open or close the aperture receiver of the apparatus for retrieving or releasing the device comprising the aperture collection pin.

One example method of operation may include determining whether a received command will be locally processed by a control device, determining an audio stream is associated with the received command, forwarding the audio stream to a server, and forwarding an audio output to a termination device based on a processed audio stream.
