The present application provides a method of manufacturing a resonant panel (200) of a flat panel loudspeaker. The method comprises: pressing a resonant panel blank between a first pressing surface (302) and a second pressing surface of a press, whereby to form the resonant panel (200) of the flat panel loudspeaker. The second pressing surface substantially opposes the first pressing surface (302). The first pressing surface (302) comprises at least one tool relief region (306, 312, 314, 316, 318), whereby to form at least one corresponding respective panel relief region (206, 212, 214, 216, 218) in a surface of the resonant panel (200).

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.

The invention relates to an enclosure for diffusing sound by reverberation comprising: —a loudspeaker comprising a fixed frame, a cylindrical support and a membrane connected to an upper bearing surface of the frame; and—a wave guide mounted on the upper bearing surface, the wave guide being substantially in the form of a truncated pyramid with a long wall forming a front face, a short wall and lateral uprights; the wave guide comprising at least one acoustic wall fastened to the lateral uprights, the acoustic wall extending tangentially relative to the generatrix line of the cylindrical support closest to the front face.

The embodiments of the present application disclose an electronic device, and the electronic device includes: a device body and a camera apparatus, where a sound-emitting device is installed in the device body, a first sound cavity is provided on the device body, the first sound cavity has an opening that communicates with the outside, the camera apparatus is detachably installed in the first sound cavity, in a case that the camera apparatus is installed in the first sound cavity, the sound cavity of the sound-emitting device has a first volume value, in a case that the camera apparatus is separated from the device body, the sound cavity of the sound-emitting device extends toward the first sound cavity and has a second volume value, and the first volume value is smaller than the second volume value.

This application discloses a microphone that includes a handle portion, a control portion, and a microphone head that are connected in sequence. The control portion includes a first circuit board and multiple light-emitting assemblies arranged along a perimeter of the control portion. The first circuit board is electrically connected to the multiple light-emitting assemblies for controlling the multiple light-emitting assemblies to emit light in a preset light-emitting mode. In the solution of this application, multiple light-emitting assemblies are arranged in the control portion, so that when in use, the color of the light and the brightness of the light-emitting assembly can be automatically changed according to the microphone song or through a control button, so that the multiple light-emitting assemblies of the microphone can illuminate in a preset manner.
