An apparatus and method are provided. The method includes reproducing, by a portable phone, multimedia content via an external output device while the portable phone is coupled with the external output device, determining whether the portable phone is decoupled from the external output device, and terminating the reproducing of the multimedia content based at least in part on a determination that the portable phone is decoupled from the external output device.

Headphones includes a pair of cups, each housing a speaker to be positioned over an ear of a user, a microphone, a processor, an actuator to move a member of at least one of the cups to uncover at least a portion of the ear of the user to expose the user to ambient sound, a user control to active a training mode of the headphones in which the processor operates the microphone to record relevant sounds occurring when the training mode is activated, the processor to subsequently analyze ambient sounds external to the headphones that are received by the microphone and compare those ambient sounds to the recorded relevant sounds and the processor to selectively activate the actuator to uncover at least a portion of the ear of the user to expose the user to ambient sound in response to determining that the ambient sounds match the relevant sounds.

Provided here are systems and method for non-intrusive authentication of a user. Such systems and methods may include in an embodiment a waveform generator to generate a message, encrypt the message, and transmit the encrypted message to one or more transmitters. The system may include a decryption engine to receive a bone conduction signal from one or more receivers, process the bone conduction signal, decrypt the processed bone conduction signal, and separate a bone conduction token portion from the decrypted bone conduction signal. The system may include an authentication engine to analyze the bone conduction signal, authenticate a user for the operation detected based on a comparison of the analyzed bone conduction signal and the pilot portion of the message exceeding a preselected threshold, and verify bone conduction signal authenticity via the bone conduction token portion and the token portion.

An audio service module is communicatively connected to an audio abstraction module. The audio abstraction module is communicatively connected to a codec driver. The codec driver is communicatively connected to a codec chip. The audio service module receives a headset insertion/removal message and sends the message to the audio abstraction module. The audio abstraction module determines a digital-to-analog converter DAC channel configuration policy in the codec chip based on the headset insertion/removal message, and sends the DAC channel configuration policy to the codec driver. A DAC channel is used to transmit earpiece or headset data, and transmit motor data to a class-D amplifier to drive the motor. The codec driver controls the codec chip to reconfigure the DAC channel based on the DAC channel configuration policy.

A headset includes an acoustic structure, a first microphone located outside the acoustic structure, a second microphone located inside the acoustic structure, and an output driver configured to receive an antinoise signal based on a combination of input from the first and second microphones. A voice signal of a user of the headset is generated using input from the first and second microphones. The first microphone could be a feed-forward microphone that provides input to a feed-forward filter to produce a filtered feed-forward signal for producing the antinoise signal. The second microphone could be a feedback microphone that provides input to a feedback filter to produce a filtered feedback signal for producing the antinoise signal.

In an example, an example hook includes a rest surface to sustain a peripheral, a retainment device switchable between a lock position and an unlock position, a lock coupleable to the retainment device to maintain the retainment device in the lock position, and a controller to actuate the lock in response to a user event. In another example, an example display device includes a housing, a hook coupled to the side wall of the housing, a retainment device coupleable to the hook, a lock to maintain the retainment device in a lock position or in an unlocked position; and a controller to activate the lock in response to a signal corresponding to an instruction to lock the retainment device and deactivate the lock in response to a signal corresponding to an instruction to unlock the retainment device based on a user event.

Disclosed are a method of controlling a display by a headset with inline control, and related devices. The method includes: detecting whether an headset jack of the display is plugged with the headset; after the headset jack of the display is determined to be plugged with the headset, inputting a detection bias voltage to the headset, and monitoring a feedback signal of the detection bias voltage; in response to detecting a change in the feedback signal of the detection bias voltage, identifying a user's control instruction to the display using the headset according to a control signal sent by the headset; and controlling the display to perform a corresponding display operation according to the control instruction.

Embodiments of this application disclose a call method and an apparatus. In the call method, when a user does not actively select an audio device as a voice pickup device and a voice play device, after establishing a call connection to another electronic device, an electronic device selects, from available audio devices, an audio device that meets a user expectation as the voice pickup device and the voice play device. According to technical solutions provided in the embodiments of this application, user experience in a call process can be improved.
