A system may obtain a set of features characterizing a segment of inertial measurement unit (IMU) data generated by an IMU of an ear-wearable device. The system may apply a machine learning model (MLM) that takes the features characterizing the segment of the IMU data as input. The system may determine, based on output values produced by the MLM, whether a user of the ear-wearable device has potentially been subject to physical abuse. The system may then perform an action in response to determining that the user of the ear-wearable device has potentially been subject to physical abuse.

A system and method for providing zone-specific media to a user. As a non-limiting example, various aspects of this disclosure provide a system and method that flexibly selects and provides media content (e.g., audio content), where such content is selected based, at least in part, on a user location (e.g., location within a premises).

A sound output control device includes: an orientation detecting unit configured to detect a state of orientation of a face of a user; an ambient sound obtaining unit configured to obtain ambient sound; an ambient sound reducing processing unit configured to perform, based on the ambient sound, processing of reducing the ambient sound; and a sound output control unit configured to cause sound to be output with the ambient sound reduced by the ambient sound reducing processing unit, when the detected orientation of the face of the user is in a first state, and make audibility of the ambient sound higher than in a state where the ambient sound has been reduced by the ambient sound reducing processing unit, when the detected orientation of the face of the user is in a second state changed from the first state.

Embodiments of the present disclosure provide an earphone debugging method and device, and a storage medium. The earphone debugging method comprises the following steps: obtaining configuration parameters to be updated of a slave earphone and configuration parameters to be updated of a master earphone by the master earphone; sending, by the master earphone, the configuration parameters to be updated of the slave earphone to the slave earphone, which allows the slave earphone to be operated according to the configuration parameters to be updated of the slave earphone; and the master earphone being operated according to the configuration parameters to be updated of the master earphone. According to the embodiments of the present disclosure, the earphone debugging efficiency is improved.

Examples described herein relate to a charging system for wireless earbuds involving charging adapters that are attachable to the wireless earbuds. In some implementations, the charging adapter is attachable to an external surface of an earbud using a magnetic or mechanical interface that align electrodes of the charging adapter with electrodes on the wireless headset, allowing an internal battery of the earbud to draw current and charge from the charging adapter while the earbud is in-ear. Then, when the internal battery is and recharged using a charging case or wall charger, the charging adapter can be detached from the earbud.

The present disclosure provides a sound producing device, at least comprising a housing assembly. The housing assembly comprises a housing and a sealing member. The housing is provided with a plug-in hole, and the plug-in hole runs through a side wall of one side of the housing; the sealing member is used for plugging and sealing the plug-in hole; the plug-in hole comprises at least one hole wall segment provided along a plugging direction of the sealing member; the cross-sectional area of a reference cross section of at least part of the at least one hole wall segment perpendicular to the plugging direction of the sealing member increases gradually along the plugging direction; the sealing member is in plugging fit with the at least one hole wall segment.

Examples described herein relate to transitioning a playback session between portable playback devices such as “smart” headphones, earbuds, and handheld speakers with playback devices of a zone-based media playback system. Exemplary techniques facilitate continuity of playback when transitioning between locations (e.g., from at home to on-the-go or vice versa) or between listening paradigms (e.g., personal or out-loud playback of audio content). An example implementation includes detecting a swap trigger, determining the source playback device(s) and target playback device(s), and performing a playback session swap between the source playback device(s) and target playback device(s).

Systems and methods for packet dynamic latency estimation for audio streams may include, for example, capturing a first audio signal using a microphone of a computing device; receiving a second audio signal at the computing device via wireless communications from an access point; determining a set of estimates of a delay of the first audio signal relative to the second audio signal based on a cross-correlation at respective analysis steps within the first audio signal and the second audio signal; determining an average delay and a confidence interval for the set of estimates of the delay; comparing the confidence interval to a threshold duration; and, responsive to the confidence interval being less than the threshold duration, playing, using a speaker controlled by the computing device, an audio signal received from the access point with an added delay determined based on the average delay.

The present disclosure provides an acoustic output apparatus including one or more status sensors, at least one low-frequency acoustic driver, at least one high-frequency acoustic driver, at least two first sound guiding holes, and at least two second sound guiding holes. The status sensors may detect status information of a user. The low-frequency acoustic driver may generate at least one first sound, a frequency of which is within a first frequency range. The high-frequency acoustic driver may generate at least one second sound, a frequency of which is within a second frequency range including at least one frequency exceeding the first frequency range. The first and second sound guiding holes may output the first and second spatial sound, respectively. The first and second sound may be generated based on the status information, and may simulate a target sound coming from at least one virtual direction with respect to the user.

An electronic device includes a speaker, a sensor, a communication circuit, a processor, and a memory to store instructions. The instructions, when executed by the processor, cause a wireless audio device to, while outputting a signal for reducing an external sound through the speaker, identify, using the communication circuit, an external electronic device, identify, using the sensor, a conversation responsive to a location of the external electronic device satisfying a specified condition, responsive to identifying the conversation, stop an output of the signal for reducing the external sound for a first period of time, and responsive to identifying a specified keyword included in the conversation, prolong stopping the output of the signal for reducing the external sound for a second period of time.
