A chair capable of providing somatosensory vibration based on an external signal comprises a body, a plurality of vibrators and a vibration controller. The body comprises a framework and a plurality of mesh fabrics disposed on the framework. The vibrators are hung on the framework through at least two connectors and are arranged corresponding to one of the mesh fabrics. Each of the plurality of vibrators is provided with a vibration surface directly contacting one of the mesh fabrics. Each of the plurality of vibrators operates based on at least one vibration starting signal. The vibration controller is disposed on the body and is in data connection with the vibrators. The vibration controller generates at least one vibration starting signal based on a received external signal, and provides at least one vibration starting signal to each of the plurality of vibrators in a wired or wireless manner.

According to an embodiment, an electronic device may comprise: a flexible display, at least one microphone, a sensor, a communication module comprising communication circuitry, and at least one processor operatively connected with the flexible display, the at least one microphone, the sensor, and the communication module. The at least one processor may be configured to: based on receiving a call signal from an external electronic device through the communication module, identify whether the call signal is a video call signal, based on the call signal being the video call signal, identify a folding state of the electronic device through the sensor, adjust a sound signal received through the at least one microphone based on the folding state, and control the communication module to transmit the adjusted sound signal to the external electronic device.

Systems and methods for dynamic voice accentuation and reinforcement are presented herein. One embodiment comprises one or more audio input sources; one or more audio output sources; one or more band pass filters; and a processing control unit that includes an audio processing unit, and which executes a method: differentiating between audio input sources as vocal sound audio input sources and ambient noise audio input sources; increasing the gain of the vocal sound audio input sources; inverting a polarity of an ambient noise signal received by each of the ambient noise audio input sources; and adding the inverted polarity to either an output signal of at least one of the one or more audio output sources, or to an input signal of at least one of the vocal sound audio input sources, to reduce ambient noise.

A method for adjusting sound playback of a portable device for constancy notwithstanding different environments outputs from the portable device detectable audio signals inaudible to user and the device receives reflected audio before the portable device is actually commanded to play an audio file. A list of volume weightings for reflected audio is calculated. Before commencing playback of the audio file, the portable device obtains reference volume weightings from a list according to the current volume setting, and calculates adjustment coefficients for different frequency bands based on weightings of the reference volume list and of the reflected audio list. The audio signals of the audio file are output after adjustment. A portable device is also disclosed.

Aspects of the subject technology relate to electronic devices having sensors such as pressure sensors. A pressure sensor may be integrated into an audio component of an electronic device such that the pressure sensor is fluidly coupled to an environment external to a device housing via at least a portion of an internal cavity of the audio component housing. The audio component housing may include an opening. The pressure sensor may be mounted adjacent to or within the opening. The opening may be sealed to prevent passage of gas or liquid through the opening. The pressure sensor may be integrally formed with an inner wall of the audio component housing. The audio component may be a speaker or a microphone.

A wireless earphone comprises a transceiver circuit for receiving streaming audio from a data source over a local ad hoc wireless network. When the data source and the earphone are out of range, they transition automatically to an infrastructure wireless network. If there is no common infrastructure wireless network for both the data source and the speakerphone set, the earphone connects to a host server via an available wireless network.

A vehicle microphone system may include at least two microphones forming a microphone array, at least one loudspeaker configured to emit audio signals. a processor coupled to a memory and programmed to receive incoming audio signals from the microphone array, determine at least one parameter for each channel of the microphone array, determine at least one filter to apply to at least one channel based on a difference between the parameters of each channel, and store the at least one filter in the memory.
