One or more accelerometers embedded with an earbud and/or a set of earphones are able to sense a moving pace of a user. Based on a moving pace of the user, a signal is sent to a remotely connected electronic device. The electronic device is able to separately increase and decrease a beat or rhythm of the audio from the electronic device based on a pace of the user. In some embodiments, an audio alert is sent to the user to inform the user of pace and whether the user has increased or decreased their pace. Additionally, in some embodiments, a program stored on the electronic device is used to compare the user's current progress and/or speed based on past runs and workouts.

A display apparatus is provided. The display apparatus includes a power supply; a connection interface; and a processor configured to: identify whether a device connected to the connection interface comprises a speaker or a wireless power transmitter, based on the device being identified as comprising the speaker, provide power supplied from the power supply and a sound signal to the speaker, and based on the device being identified as comprising the wireless power transmitter, provide power supplied from the power supply to the wireless power transmitter.

Provided is an apparatus that includes a speaker, a memory, and a processor operatively connected to the speaker and the memory. The processor is configured to: identify whether audio output is provided via the speaker when an external device is detected; determine, based on whether the audio is output via the speaker, whether to apply output conversion effects; and control, based on the determination, the audio output via the external device. Various other embodiments including a method thereof are also possible.

A detachable headband for a headphone system can incorporate a headband identification circuit that stores or encodes a headband identification parameter value. When the headband becomes attached to an ear cup, the headband can transmit the headband identification parameter value to the ear cup.

A three-dimensional virtual reality vest; the three-dimensional virtual reality vest may be beneficial for use by a user to enhance virtual reality, video game, movie, or other media experiences. The three-dimensional virtual reality vest includes a vest garment having a surround sound speaker system, a series of embedded haptic feedback devices, and additional features configured to provide an immersive three-dimensional user-experience for a user when worn.

The present invention provides a judging circuit including a comparison module and a control module for positive and negative terminals of an earphone MIC and a method thereof, and an electronic device; the control module controls any one first terminal of two terminals of the MIC to inject an excitation current, and control the other second terminal of the two terminals to be connected to the ground via an analog switch, also to judge whether the first terminal and the second terminal is the positive terminal or the negative terminal according to comparison result information; the comparison module compares the current voltage with a preset reference voltage value after excitation current is injected into the first terminal and the second terminal is grounded to obtain comparison result information and to send it to the connected control module. The present invention improves the flow and process without two sets of detection device.

An audio apparatus includes a network interface, a receiver, at least one storage, and at least one processor. The processor is configured to determine that the audio apparatus is in a state capable of communicating with the other audio apparatus via the network interface. The processor is also configured to receive audio data via the receiver transmitted from an external apparatus different from the other audio apparatus. The processor is also configured to output a sound based on the received audio data. The processor is also configured to transmit the sound emission control information stored in the at least one storage to the other audio apparatus. The sound emission control information includes one or more of a sound volume, and a frequency band.

This application relates to audio driving circuitry (100), and in particular to audio driving circuitry for outputting first and second audio driving signals for driving a stereo audio load (106), which may be a stereo audio load of an accessory apparatus (102) removably coupled to the audio driving circuitry in use. A load monitor (111) is provided for monitoring to monitor, from a monitoring node (112), an indication of a common mode return current passing through a common return path, together with an indication of a common mode component of the first and second audio driving signals and to determine an impedance characteristic of the stereo audio load. The load monitor (111) can provide dynamic monitoring of any significant change in load impedance. In some embodiments the load monitor (111) comprises an adaptive filter (301) which adapts a parameter of the filter which is related to the load impedance so as to determine the indication of load impedance.

Embodiments of an electronic device are disclosed. The electronic device may include a USB Type-C connector including at least one configuration channel (CC) pin and a processor operatively connected to the USB Type-C connector. The processor may be configured to: obtain first information of a connected audio output device by using a USB driver; transmit the first information and/or audio card information of the audio output device to an audio framework through a USB framework; control the audio framework to access an interface corresponding to the audio card information; and activate, when at least a portion of second information of the audio output device is obtained through the USB driver while accessing the interface, the interface by transmitting the at least a portion of the second information to the audio framework through the USB framework. Various additional embodiments in addition to the disclosed embodiments are possible.

There is provided a smart audio system including multiple audio devices and a central server. The central server confirms a model of every audio device and a position thereof in an operation area in a scan mode. The central server confirms a user position or a user state to accordingly control output power of a speaker of each of the multiple audio devices in an operation mode.
