    摘要： An outdoor speaker system including a housing configured to accommodate a speaker unit, a top panel, a bottom panel, a front panel, and at least one side panel. The housing is encased by the top, bottom, front, and at least one side panel. The outdoor speaker system further includes a computing device and a plurality of solar panels that provide power to the outdoor speaker system and/or any external device. The computing device includes control buttons to control and interface with the speaker unit. The plurality of solar panels includes a top solar panel configured to couple to the top panel and a continuous solar panel configured to couple to at least two sides of the housing. The continuous solar panel receives solar energy from the sun regardless of what direction the outdoor speaker system is facing such that the outdoor speaker system is provided with sufficient power.

    摘要： An innovative system for transmitting encrypted 1-bit audio over an Ethernet network comprises using an omni-directional micro-electrical-mechanical system acoustic sensor element to provide an analog input signal to a sigma-delta modulator that then creates a pulse density modulated 1-bit data stream, at an audio oversampling rate, to a first input of a first exclusive-or (XOR) logic gate. The second input of the XOR logic gate is simultaneously presented with a first pseudo-random 1-bit data stream, at the same audio oversampling rate, thereby resulting in an encrypted pulse density modulated (PDM) 1-bit data stream at the output of the XOR logic gate. The encrypted PDM 1-bit data stream is clocked into a first-in first-out (FIFO) memory at the audio oversampling rate and is clocked out of the first FIFO memory as Ethernet PDM frame data packages at a predetermined Ethernet PHY transfer rate.

    摘要： A noise-reducing preamp system includes: a power supply circuit configured to provide electrical power to the noise-reducing preamp system and including a 0 volt reference; a signal amplification circuit including: a preamplifier circuit having an external reference input terminal and configured to receive an analog input signal, and a variable gain controller circuit configured to control the gain of the preamplifier circuit, wherein the signal amplification circuit is configured to amplify the analog input signal to generate an analog amplified signal; and a DC offset and biasing circuit coupled to the preamplifier circuit and the 0 volt reference of the power supply circuit, the DC offset and biasing circuit configured to: receive the 0 volt reference as a feedback signal, process the analog amplified signal to remove a DC offset and generate an analog output signal, and provide the analog output signal to the external reference input terminal of the preamplifier circuit of the signal amplification circuit; wherein the noise-reducing preamp system is configured to provide the analog amplified signal to an external device.

    摘要： This disclosure provides methods, components, devices and systems for low-latency parameter updates. In some aspects, a wireless communication device, such as a handset or an access point (AP), may transmit, to one or more wireless audio devices, an indication of a set of updated parameters associated with an extended personal area network (XPAN) of the wireless communication device. The wireless communication device may embed the indication of the set of updated parameters via a real-time protocol (RTP) header or in a padding section of a payload data of an audio data packet. A wireless audio device may extract the set of updated parameters from the audio data packet and may transmit an acknowledgement (ACK) to the wireless communication device. As a result of receiving an ACK from the wireless audio device(s), the wireless communication device may communicate with the wireless audio device(s) in accordance with the updated parameters.
