Disclosed examples generally include methods and apparatuses related to microphone units, such as may be found in implantable medical devices (e.g., cochlear implants). Microphone units generally include a microphone element connected to a chamber having a concave floor with the chamber covered by a membrane. Microphone units can be configured to produce an output based on pressure waves (e.g., sound waves) that reach the membrane. In an example, a microphone unit has a pressurized gas within the chamber below the membrane such that, while in a static state, the membrane deflects away from the chamber floor.

An electronic device according to various embodiments may include: a camera module including a camera; a speaker module including a speaker disposed in a first direction with respect to the camera module; a first support including a speaker support configured to support the speaker module and a camera support configured to support the camera module; a second support having at least a portion coupled to the first support; a sound hole connected to an outside of the electronic device; a first sound outlet positioned in the first direction with respect to the camera module and connected to the sound hole; a second sound outlet positioned in a second direction opposite to the first direction with respect to the camera module and connected to the sound hole; a first sound channel configured to connect the speaker module and the first sound outlet; and a second sound channel configured to connect the speaker module and the second sound outlet, wherein the second sound channel may include a space provided between the camera support of the first support and the second support.

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.

The present disclosure presents a communication device configured to removably attach to a mask, and to receive, transmit, and amplify sound and/or speech from a wearer.

A loudspeaker includes a support, a magnetic assembly, a first vibration assembly, and a second vibration assembly. The first vibration assembly and the second vibration assembly are respectively arranged on a first side and a second side opposite to the first side of the support; the first vibration assembly includes a first voice coil and a first vibration diaphragm, the second vibration assembly includes a second voice coil and a second vibration diaphragm, the first vibration diaphragm and the second vibration diaphragm are both connected to the support; and the support is provided with an accommodating space for arranging the magnetic assembly, a magnetic gap is formed between the magnetic assembly and the support, the first voice coil and the second voice coil are both at least partially located in the magnetic gap, the first vibration assembly and the second vibration assembly emit ultrasonic waves having different frequencies.

A loudspeaker enclosure comprising a plurality of acoustic sources and having controlled broad-band directivity.

Disclosed are a display panel and a sound box. The display panel includes a screen body, a cover plate, a protrusion portion, a first adhesive portion and a second adhesive portion. The first adhesive portion is filled between a region of the cover plate exposed from the protrusion portion and the screen body, and the second adhesive portion is filled between the protrusion portion and the screen body, such that no gap is generated between the cover plate and the screen body and between the protrusion portion and the screen body, so as to eliminate bubbles visible to human eyes after a defoaming treatment of the screen body and the cover plate, thereby improving a display effect of the display panel.
