The present disclosure relates generally to providing a flexible patch and system for communicating through hard plastic masks such as CPAP/BiPAP® masks. Using electronic circuitry and novel designs, the present systems and methods can detect speech vibrations and output audible speech from hard plastic mask wearers. For example, in certain embodiments, the present systems and methods can recognize speech through a CPAP/BiPAP® mask, filter out non-human voice related noise, and output the resulting speech of the mask wearer.

A light speaker structure with a ring handle includes a speaker body, a speaker enclosure, a lighting mechanism and an auxiliary mechanism. The speaker body is mounted within the speaker enclosure, and the auxiliary mechanism is mounted on the speaker enclosure. The lighting mechanism includes a lampshade, a light strip, and LED beads. The light strip is mounted within the lampshade. The LED beads are fixedly connected to the light strip and electrically connected to the speaker body. The light strip is disposed in a laterally inverted C-shape around the speaker enclosure. The lampshade covers the light strip, so that the light strip is held between the lampshade and the speaker enclosure. The light strip and the lampshade are so shaped that they can be arranged around the speaker enclosure, thereby achieving a better lighting effect, providing a larger lighting area and producing a stereoscopic effect.

A voice conversation apparatus includes a microphone configured to convert a voice of the one speaking person into a voice signal, modulation means configured to modulate the voice signal into a signal using ultrasound as a carrier wave, sound wave emission means configured to emit the signal modulated by the modulation means as a sound wave using ultrasound as a carrier wave, alignment means used by the one speaking person to make alignment so that the sound wave emission means is oriented to another voice conversation apparatus, pairing means configured to perform a pairing process of connecting the voice conversation apparatus to the other voice conversation apparatus by near-field communication, and control means configured to receive an instruction to start a conversation from the one speaking person and to, when the pairing process is successful, cause the sound wave emission means to emit the sound wave.

An electronic device includes: a power supply device, a first audio-visual device and a second audio-visual device. The first audio-visual device is detachably connected with the power supply device. The second audio-visual device is detachably connected with the power supply device. When the first audio-visual device is connected with the first power supply device, the power supply device charges the first audio-visual device.

A goods processing apparatus includes a controller including a program memory, a security module, a first communication interface that is configured to, in cooperation with the security module, securely communicate with a remote server, and an acoustic output device electrically connected with the controller and configured to output audio files or sound files. The security module and the first communication interface can be electrically connected with the controller. The program memory may store a program to control the acoustic output via the acoustic output device. The program can facilitate external commands being transmitted from the remote server, or from one or more other internet sources, to the controller. Via security measures, operational security of the goods processing apparatus is prevented from being negatively affected, or harmful code is prevented from being transmitted to controller.

A rear side of a vibration part of a speaker is covered by a cover member, and a duct is provided at the cover member. The cover member has a recessed portion, and an air flow path is formed inside the recessed portion. A circuit part is mounted on an outer surface of the cover member, and a heat sink provided in the air flow path is connected to the circuit part to allow heat conduction. Due to vibration of the vibration part, an airflow in the air flow path is accelerated and thus the effect of dissipating heat from the heat sink is increased.

According to one example, an audio door system includes a door, an audio system, an amplifier, and an exciter. The audio system is coupled to the door. The amplifier is coupled to the door, and is electrically coupled to the audio system. The exciter is coupled to the door, and is electrically coupled to the amplifier. The exciter can transform an audio electrical signal into mechanical energy, and can further cause a surface of the door to transform the mechanical energy into one or more acoustic sound waves.

Bass reflex type loudspeaker enclosure comprising a cabinet, a loudspeaker and a first vent. The acoustic loudspeaker enclosure further comprises a second vent and an internal heat sink which is located inside the cabinet and intended to be thermally coupled to an electrical component in order to dissipate, inside the cabinet, heat produced by the electrical component, the first vent, the second vent and the internal heat sink being positioned so that an air flow which flows through the first vent, the second vent and into the cabinet moves the heat produced by the electrical component out of the cabinet.

The present invention relates to a method and apparatus for providing and/or receiving audible sound. In particular, the invention relates to apparatus, such as a micro speaker, which includes an active region which comprises an adsorbent element in the form of a self-supporting monolith-like element with a porous reticulated structure. The adsorbent element includes adsorbent material which comprises microporous organic polymer (MOP) material. The apparatus of the present invention is suitable for use in an electronic device, for example a mobile or portable electronic device, to provide improved audible sound.

A loudspeaker system is provided herein comprising: a digital transmitter adapted to store, retrieve, and transmit digital messages over a network cable using an audio over internet protocol (AoIP), and wherein the transmitted digital messages are individually addressable using an IP address, and wherein the transmitted digital messages contain digital audio messages and digital command and control messages; an endpoint enclosure adapted to have a unique IP address pre-assigned to it such that the endpoint enclosure is adapted to receive the transmitted digital messages addressed to it and extract the digital audio messages and the digital command and control messages from the transmitted and received digital messages, and wherein the endpoint enclosure comprises additional circuitry adapted to extract the digital audio messages from the received digital messages and power from the network cable, and generate an electrical audio signal from the extracted digital audio messages; an “N” position switch adapted to receive the electrical audio signal from the additional circuitry and output the same on one or more of “N” output ports based on the position of the switch; and a first set of loudspeakers adapted to receive the electrical audio signal and broadcast the same as an acoustic audio signal.
