Abstract: Embodiments provide an ear pad having an annular structure. The ear pad includes an inner layer and an outer layer covering the inner layer. The inner layer and the outer layer are separate of annular structures and are separated by a first medium layer. The inner layer coats a second medium layer. Acoustic impedance of the first medium layer is different from acoustic impedance of the inner layer and the outer layer. The ear pad is configured to close a front cavity space between a housing and an ear of a user, thereby preventing sound leakage and reducing external noise entering the ear of the user. Various ear pad embodiments provide a double-layer structure including the inner layer and the outer layer separated by the first medium layer.

Abstract: A wearing detection method, a wearable device, and a storage medium are provided. When the wearable device does not play audio and obtains a first audio signal captured by the microphone, the wearable device outputs a second audio signal by using the speaker, obtains a third audio signal captured by the microphone, obtains a signal feature of the third audio signal, and determines a wearing status of the wearable device based on the signal feature of the third audio signal. In this way, the wearing status of the wearable device can be determined by outputting the second audio signal and performing feature analysis on the corresponding input third audio signal, without a need of an additional sensor, thereby reducing sensor stacking.

Abstract: An earphone and a mobile terminal is provided, in which the earphone includes a housing and a speaker assembly. The housing internally includes a front cavity and a rear cavity that are separated by the speaker assembly. The front cavity is located on a side that is of the speaker assembly and that is a sound output direction, and the rear cavity is located on an opposite side of the sound output direction of the speaker assembly. One or more sound guide channels are disposed in the housing, each sound guide channel is disposed in a sidewall of the housing, and each sound guide channel is configured to: when the earphone is normally worn, connect air inside an ear canal of a user to air outside the ear canal without connecting air in the front cavity to air in the rear cavity.

Abstract: The present disclosure provides a speaker box. The speaker box includes an upper housing, a lower housing forming an accommodating space together with the upper housing, and a speaker unit accommodated in the accommodating space. The speaker unit includes a diaphragm configured to vibrate and produce sound. The diaphragm is disposed separately from the upper housing to define a front acoustic cavity. The speaker box further includes a sound channel communicating the front acoustic cavity with an external environment. The front acoustic cavity and the sound channel constitute a front cavity of the speaker box together. A baffle fixedly connected to the upper housing is disposed in the sound channel. The baffle and the upper housing define a resonant cavity in communication with the front acoustic cavity, and the resonant cavity has an inlet facing to the front acoustic cavity.

Abstract: The present disclosure relates to the field of electronic technologies, and discloses an electronic device. The electronic device includes a vibration plate, and a frame for supporting the vibration plate. The frame includes a supporting portion opposite to and parallel to the vibration plate, and a border bent at an edge of the supporting portion and extending along the edge in two opposite directions. The vibration plate is supported by the supporting portion and a gap is reserved between the vibration plate and the border. An actuator is fixed to a surface of the vibration plate facing the supporting portion, and the actuator drives the vibration plate to vibrate and sound. A damper is provided between the vibration plate and the supporting portion. Compared with the prior art, the electronic device provided by the present disclosure can alleviate the vibration of the frame during sounding.
