An apparatus comprises an electronic device having at least one speaker and a passive sound proliferation device comprising an audio cavity. The audio cavity is configured to proliferate acoustic waves therefrom and is defined by at least a substantially planar back wall, a substantially planar side wall, an arcuate surface between the substantially planar side wall and the substantially planar back wall, and a substantially planar inner bottom surface. The passive sound proliferation device may further include a substantially planar outer side surface and a substantially planar outer bottom surface substantially perpendicular to the substantially planar outer side surface. The electronic device may be disposed within the audio cavity. Related methods of directing audio from a passive sound proliferation device are disclosed.

Systems and apparatuses for supporting electronic devices are described. Such systems and apparatuses provide significant adaptability to position an electronic device in commonly used locations by using an interface that is readily provided in virtually any location. Furthermore, the systems and apparatuses described herein include cradles that adaptable to a wide array of electronic device dimensions, including width and depth or thickness.

An extendable speaker system is provided with a base and lid that are connected via a plurality of concentric collapsible hollow bodies such as cylinders. A woofer speaker resides in the base. Mid range or tweeter speakers reside in the lid. The lid is displaced away from the base to expand the speaker system, where the extended cylinders provide an airtight seal between the base and lid forming a woofer speaker enclosure therein. Friction seals between the cylinders, a spring residing within the speaker enclosure, and the airtight speaker enclosure itself provide a collective force sufficient to maintain the speaker system in an extended configuration. A port is opened by depressing a button to vent the enclosure to allow for the speaker system to be collapsed. A locking system is provided to releasably maintain the speaker system in a collapsed configuration.

An entertainment system is provided, the system comprising a portable media device configured to simultaneously produce an audible output signal and a plurality of vibratory output signals, the audible output signal representing a multi-track recording comprising a plurality of individual recorded tracks, each vibratory output signal based on at least one individual recorded track; and a plurality of actuators positioned at various locations on a user's body, each actuator configured to receive a respective one of the vibratory signals and to vibrate based on the received signal. A method of mixing a multi-track vibratory recording is also provided, the method comprising utilizing an entertainment system to feel vibrations representing individual recorded tracks on different locations of a user's body; and for each actuator, selecting at least one of the tracks based on suitability for driving the actuator, and providing, to the actuator, a vibratory signal derived from the selected track.

A portable speaker assembly includes a first shell that may insertably receive an electronic device. The first shell is comprised of a rigid material to protect the electronic device from impact damage. A second shell is slidably coupled to the first shell such that each of the first shell and the second shell form a case. The second shell insertably receives the electronic device. The second shell is comprised of a rigid material to protect the electronic device from impact damage. An audio unit is coupled to the case to emit audible sounds outwardly from the case. The audio unit is in wireless electrical communication with the electronic device thereby facilitating the audio unit to receive an audio signal from the electronic device.

A furniture system includes a base and transverse member, with an induction charger provided in the transverse member and/or base, hidden from view and feel. The induction charger can be at least partially secured to either the base frame or the transverse member frame. The induction charger provides induction charging to a device positioned adjacent to a charging surface of the base or transverse member. The charging surface is positioned adjacent to the induction charger. Additionally, the induction charger is positioned between a first and second cushioning material. The first cushioning material is adjacent to (e.g., proximal to or on) the charging surface. The first and second cushioning materials have respective depths.

Disclosed are an apparatus and method of processing an audio signal to optimize audio for a room environment. One example method of operation may include recording the audio signal generated within a particular room environment and processing the audio signal to create an original frequency response based on the audio signal. The method may also include identifying a target sub-region of the frequency response which has a predetermined area percentage of a total area under a curve generated by the frequency response, determining whether the target sub-region is a narrow energy region, creating a filter to adjust the frequency response, and applying the filter to the audio signal.

Systems and method are disclosed for facilitating efficient calibration of filters for correcting room and/or speaker-based distortion and/or binaural imbalances in audio reproduction, and/or for producing three-dimensional sound in stereo system environments. According to some embodiments, using a portable device such as a smartphone or tablet, a user can calibrate speakers by initiating playback of a test signal, detecting playback of the test signal with the portable device's microphone, and repeating this process for a number of speakers and/or device positions (e.g., next to each of the user's ears). A comparison can be made between the test signal and the detected signal, and this can be used to more precisely calibrate rendering of future signals by the speakers.

A portable auxiliary unit for coupling with a mobile audio player is disclosed. The auxiliary unit provides both auxiliary power input and auxiliary audio output for the player, as well as a protective casing in the form of a receiving cup open on a top side. The receiving cup provides access to inputs and outputs on the audio player accessible by cabling from the auxiliary unit installed when an access panel is opened. The auxiliary unit has an integral rechargeable battery pack and a speaker assembly connectable to the audio player via the cables.

In addition to other aspects disclosed, a docking station that receives content through a wired connection from a handheld media device, plays or displays the content through a speaker, and transmits content to a remote speaker.
