Various implementations include portable speakers configured to adjust audio output based on detected input connections. In certain cases, a portable speaker includes: an enclosure housing: at least one electro-acoustic transducer for providing an audio output; a processor coupled with the transducer; an audio input module coupled with the processor for receiving audio input signals; and a battery configured to power the at least one transducer, the processor, and the audio input module; an input channel for receiving a hard-wired audio input connection; and at least one wireless input channel for receiving an audio input from a source device via a wireless connection, where the processor is configured to: adjust an audio signal received from the hard-wired audio input connection if a source device is already connected via the wireless connection.

A portable digital audio system for a musician. The digital audio system includes an amplifier for processing an audio signal from a musical instrument or microphone electronically connected to the digital audio system and a speaker for playing a sound associated with the audio signal processed by the amplifier. The portable digital audio system also includes an audio control system providing operational control of the digital audio system and a primary housing for supporting the amplifier, the audio control system, and the speaker. Further, the digital audio system has a touch screen display in electronic communication with the audio control system and supported by the primary housing.

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 speaker device for reproducing sound within a predetermined audio spectrum is provided. The speaker device comprises: a housing including a top, a bottom, and a side surface; at least one speaker disposed within the housing, the at least one speaker including a speaker flange facing towards the bottom; a waveguide including at least a first surface defining at least one sound channel for conducting a given sound produced by the at least one speaker, and the at least one channel includes a first zone, a second zone, and a third zone sequentially defined along a length thereof to provide for sound reproduction from 100 Hz to 20000 Hz.

A protective face mask implemented with a pocket located on a front surface of the mask A removable amplifier unit configured to be placed into the pocket, the removable amplifier unit comprising: a micro-processor configured to process voice data; a rechargeable battery coupled to the micro-processor; a Bluetooth device coupled to the micro-processor; a microphone coupled to the micro-processor and configured to provide the voice data to the micro-processor; and a speaker unit configured to output the voice data processed by the micro-processor.

An electronic furniture assembly of the present invention includes: (i) a furniture assembly comprising: (A) a base (e.g., a seat portion), (B) at least one transverse or upright member (e.g., a side, armrest or backrest), and (ii) a speaker system mounted within one or more portions of the furniture assembly. A method of tuning a speaker of an audio-enhanced furniture system includes presenting a user with predetermined tuning profiles corresponding to a plurality of configuration footprint shapes in which the furniture assembly can be assembled and in response to a user selection of a given configuration footprint shape, tuning the speaker system according to the tuning profile selected by the user.
