Various implementations include audio devices and components of such devices. Certain implementations include an audio device with a sealing member for providing a substantially water resistant seal. Certain additional implementations include an audio device with an internal heat sink for transferring heat away from device components such as a control module.

The invention provides a sounding device. The sounding device comprises a housing body with an accommodating space, a one-way inlet valve and a one-way outlet valve. A speaker unit partitions the accommodating space into a front cavity and a back cavity. The one-way inlet valve communicates the outside and the back cavity and is used for introducing air into the back cavity. The one-way outlet valve communicates the back cavity and the outside and is used for discharging the air in the back cavity outside. A first through hole communicating the outside and the back cavity is formed in the housing body. The invention also provides a mobile terminal. Compared with the related art, the sounding device and the mobile terminal of the invention have better reliability and better performance.

This document describes a passive thermal-control system that can be integrated into an electronic speaker device and associated electronic speaker devices. The passive thermal-control system uses an architecture that combines heat spreaders and thermal interface materials to transfer heat from heat-generating electronic devices of the electronic speaker device to a housing component of the electronic speaker device. The housing component dissipates the heat to prevent a thermal runaway condition.

A speaker includes a sound box, a speaker module, and a heat pipe. The sound box includes a first opening and a second opening. The speaker module is hermetically connected to the first opening. The heat pipe is hermetically connected to the second opening. The heat pipe includes a first end and a second end. The first end is located in the sound box. The second end is exposed to the second opening. The speaker module is fixedly connected to at least part of an outer wall of the heat pipe. In the speaker, a hollow heat pipe is fixedly connected to the speaker module, and vibration of the speaker module drives air in the heat pipe to flow to dissipate heat from the heat pipe. Further, the cold heat pipe carries heat away from the speaker module through heat transfer, thereby dissipating heat from the speaker.

Systems, methods, and computer-readable media are disclosed for voice activated devices with integrated heatsinks and speakers. In one embodiment, an example voice activated device may include a housing having an upper portion and a lower portion, a speaker housing, a heatsink coupled to the speaker housing, where the heatsink and the speaker housing together form a sealed chamber, a first speaker coupled to the speaker housing and partially disposed within the sealed chamber, where the first speaker is oriented to output audio towards the upper portion of the housing, and a light ring disposed about the lower portion of the housing.

A display apparatus includes a display panel configured to display an image, and a sound generating device on a rear surface of the display panel and configured to vibrate the display panel to generate sound, wherein the sound generating device includes a plate, a magnet and a center pole on the plate, and an oval-shaped bobbin around the center pole.

The present disclosure provides a speaker vibration assembly and speaker. The speaker vibration assembly driven by a speaker driving module to vibrate, which comprises a first frame body, a vibrating diaphragm, and a plurality of covering members. The first frame body comprises a hollow part. The vibrating diaphragm is disposed at the first frame body and covers the hollow part. The vibrating diaphragm comprises a plurality of first openings. The plurality of covering members are disposed at the vibrating diaphragm and respectively cover the plurality of first openings. Each of the covering members comprises a plurality of through holes. The speaker comprises a speaker vibration assembly according to the above description and a driving module. The driving module is connected with the first frame body and driving the first frame body to vibrate.

Provided is a speaker, including a frame; a vibration unit fixed to the frame; and a magnetic circuit unit driving the vibration unit to vibrate and produce sound and provided with a magnetic gap. The vibration unit includes a diaphragm, a voice coil, and an elastic support assembly; the diaphragm includes a diaphragm body, a diaphragm fixing portion, and a diaphragm supporting portion; the vibration unit further includes a fixing ring; and the elastic support assembly includes an elastic member fixed to a side of the fixing ring close to the diaphragm, and an auxiliary diaphragm provided on a side of the elastic member away from the diaphragm; and the diaphragm supporting portion is fixed to a side of the elastic member away from the fixing ring. With this structure, the overall strength and reliability of the speaker can be improved.

An electromechanical transducer (e.g., 200 or 300) includes a motor structure and voice coil winding support structure or former (203 or 303) configured with a vented annular spacer (e.g., 250) and vented distal pole tip member (e.g., 255) having aligned radial channels aimed to transport heat away from a voice coil (202 or 302) during the transducer's reciprocating movement while providing an extended, linear dynamic range and continuous cooling for the voice coil. A dual magnetic gap embodiment has an inside annular spacer member (e.g., 355A) and a co-planar outside annular spacer member (e.g., 350-O), each made of a thermally conductive steel alloy.

The present invention discloses a speaker device. The speaker device comprises a speaker box, a heat source, and a heat conducting member; the speaker box comprises a housing, a speaker, a sound-guiding channel, and a heat conducting plate; the speaker includes a diaphragm, the first receiving space is divided into a front sounding chamber and a back chamber, and the sound-guiding channel communicates the front sounding chamber with the outside and forms a front chamber together with the front sounding chamber; the housing having an opening penetrating therethrough, the opening communicates with the front chamber, and the heat conducting plate covers on the opening, an adjusting hole penetrates through the housing and communicates with the back chamber; an valve covers on the adjusting hole and a controller for outputting a control signal to control the valve to open or to close.
