An audio emitting pillow assembly includes a pillow that can be positioned around a user's neck. The pillow has a pair of prominences extending upwardly from the pillow and each of the prominences is positioned adjacent to a respective one of the user's ears when the pillow is positioned around the user's neck. A communication unit is integrated into the pillow and the communication unit receives streaming audio from the personal electronic device. A pair of speakers is each integrated into a respective one of the prominences and each of the speakers is aligned with a respective one of the user's ears when the pillow is positioned around the user' neck. Each of the speakers is in communication with the communication unit to audibly emit the streaming audio from the personal electronic device thereby facilitating the user to enjoy the streaming audio.

A charging dock applied in an intelligence loudspeaker box, includes a shell, a battery module and a charging cable. The intelligence loudspeaker box has a charging hole. A top surface of the shell is recessed downward to form a receiving space equipped with a pogo pin connector. The intelligence loudspeaker box is received in the receiving groove. One end of the pogo pin connector is connected to the intelligence loudspeaker box. The battery module is disposed in the shell. The battery module includes a circuit board. A top surface of the circuit board is equipped with a docking element. The docking element is connected to the other end of the pogo pin connector. One end of the charging cable is connected to the charging hole, and the other end of the charging cable is connected to a power unit.

There is provided an electronic device having Bluetooth communication function. The electronic device confirms whether a current packet received in a receive slot is a retransmitted packet according to a SEQN bit in the packet header so as to determine whether to continuously turn on an RF receiver in the receive slot or early turn off the RF receiver to save power.

Various examples are provided for surveillance of an audio stream. In one example, a method includes identifying presence or absence of a sound type of interest at a location during a time period; selecting the sound type from a library of sound type information to provide a collection of sound type information; incorporating the collection on a device proximate to the location; acquiring an audio stream from the location by the device to provide a locational audio stream; analyzing the locational audio stream to determine whether a sound type in the collection is present in the audio stream; and generating a notification to a user or computer if a sound type in the collection is present. The device can acquire and process the audio stream. In another example, a bulk sound type information library can be generated by identifying sound types of interest including them based upon a confidence level.

A wearable device can provide an audio module that is operable to provide audio output from a distance away from the ears of the user. For example, the wearable device can be worn on clothing of the user and direct audio waves to the ears of the user. Such audio waves can be focused by a parametric array of speakers that limit audibility by others. Thus, the privacy of the audio directed to the user can be maintained without requiring the user to wear audio headsets on, over, or in the ears of the user. The wearable device can further include microphones and/or connections to other devices that facilitate calibration of the audio module of the wearable device. The wearable device can further include user sensors that are configured to detect, measure, and/or track one or more properties of the user.

A wearable electronic device (WED) corrects an error where a user hears binaural sound. A processor processes sound into binaural sound that localizes to the user at a location, and the WED determines a gaze direction of the user when the user hears the binaural sound. The WED corrects an error between the location and the gaze direction.

This application provides a speech signal processing method and apparatus, and relates to the field of signal processing technologies and earphone, to monitor an ambient sound signal and improve a monitoring effect and user experience. The method is applied to an earphone, where the earphone includes at least one external speech collector. The method includes: preprocessing a speech signal collected by the at least one external speech collector, to obtain an external speech signal; extracting an ambient sound signal from the external speech signal; and performing audio mixing processing on a first speech signal and the ambient sound signal based on amplitudes and phases of the first speech signal and the ambient sound signal and a location of the at least one external speech collector, to obtain a target speech signal.

A monitor system is provided for wireless communication between a message source and a wearer needing guidance or information from the message source. The monitor system includes a wireless earpiece speaker device. A short-range radio receiver is coupled to the earpiece device. A transceiver in the system includes a long-range radio frequency receiver to receive a long-range radio frequency signal from an ultrahigh frequency (UHF) band source or a very high frequency (VHF) band source. The transceiver also includes a short-range transmitter module that converts the long-range radio frequency signal into a short-range radio frequency signal and communicates the short-range frequency signal to the earpiece speaker device.

This application discloses a method for determining a wearing status of a wireless earphone and a wireless earphone. The method includes: obtaining a first output of a sensor system, where the first output indicates a moving status of a housing, and determining, based on the first output, whether a body portion is put in a user's ear. This application further discloses a method for determining a double-tapped status of a wireless earphone and a wireless earphone. The method includes: obtaining a first output of a sensor system, where the first output indicates a moving status of a housing, and determining, by using a neural network model and by using the first output as a model input, whether the housing is double-tapped by an external object. This application improves accuracy of identifying the wearing status of the wireless earphone and improves accuracy of identifying the double-tapped status of the wireless earphone.

A terminal for controlling a wireless sound device can include a communication interface configured to wirelessly connect to at least one or more wireless sound devices; and a processor configured to transmit and receive a positioning signal to and from the at least one or more wireless sound devices, determine a relative position of the at least one or more wireless sound devices based on the positioning signal, receive an acceleration sensor value from the at least one or more wireless sound devices, determine a posture of the at least one or more wireless sound devices based on the acceleration sensor value, determine a wearing state of the at least one or more wireless sound devices based on the relative position and the posture of the at least one or more wireless sound devices, and transmit an audio signal to a worn wireless sound device among the wireless sound devices.
