The bus connects various components of the device electronic controller including the device memory 115 to the device electronic processor 110. The device memory 115 includes read only memory (ROM), random access memory (RAM), an electrically erasable programmable read-only memory (EEPROM), other non-transitory computer-readable media, or any combination thereof. The device electronic processor 110 is configured to retrieve program instructions and data from the device memory 115 and execute, among other things, instructions to perform the methods described herein. Additionally or alternatively, the device memory 115 is included in the device electronic processor 110. The device input/output interface 120 includes routines for transferring information between components within the device electronic processor 110 and other components internal and external to the synchronous media device 105. In some embodiments, the speaker unit 100 also includes, among other things, a plurality of passive and active components such as resistors, capacitors, inductors, integrated circuits, and amplifiers, such as channel inhibition circuitry 125. These components are arranged and connected to provide a plurality of electrical and acoustic functions to the speaker unit 100 including, among other things, filtering, signal conditioning, voltage regulation, or selective inhibition of one or more electrical signals, such as an audio channel. For example, selective inhibition of one or more electrical signals may be accomplished by connecting a signal line to a dump resistor or leaving a signal line open or floating. In one embodiment, selective inhibition is accomplished by connecting an input of a splitter circuit to an electronic signal line and connecting less than all of the outputs of the splitter circuit to downstream components. For example, splitter circuitry may include a single input and two outputs. In this embodiment, one of the outputs is selected to not be connected to a downstream component and is left open.

A device power source 130 supplies a nominal AC or DC voltage to the synchronous media device 105. In some embodiments, the device power source 130 supplies the nominal AC or DC voltage to additional devices within the speaker unit 100. In some embodiments, the device power source 130 is retained in the housing 135 of the speaker unit 100. In some embodiments, the synchronous media device 105 is retained in the housing 135 of the speaker unit 100. In some embodiments, the device power source 130 is powered by one or more batteries or battery packs included in the housing of the speaker unit 100 (for example, rechargeable batteries). Alternatively or in addition, the device power source 130 is powered by mains power having nominal line voltages between, for example, 100 volts AC and 240 volts AC and frequencies of approximately 50 hertz to 60 hertz. In some embodiments, the speaker unit 100 is coupleable to mains power to recharge the device power source 130. In some embodiments, the device power source 130 is configured to supply lower voltages to operate circuits and components within the speaker unit 100.

The source user interface 235 is included to control the source device 200 or the operation of one or more speaker units 100. The source user interface 235 is operably coupled to the source electronic controller 205 to control, for example, the selective inhibition of one or more audio signals at one or more speaker units 100 via the source transceiver 230. The source user interface 235 can include any combination of digital and analog input devices required to achieve a desired level of control for the system. For example, the source user interface 235 can include a touch-screen display, a plurality of knobs, dials, switches, buttons, and the like.

In some embodiments, the source device 200 continuously or periodically determines its location via one or more of the source sensors 240 and sends its determined location to one or more of the speaker units 100 via the source transceiver 230. In such embodiments, the device electronic processor 110 can use the received location of the source device 200 to operate the speaker, for example, to modify an amplitude or delay of an audio signal. In some embodiments, the source transceiver 230 sends location signals to one or more speaker units 100. In such embodiments, the device electronic processor 110 determines a relative position of the speaker 100 unit to the source device 200 based on measured signal strengths of the location signals received via the synchronous media transceiver 140 and operates the speaker 150 such that sounds from a plurality of speaker units 100 are synchronously received at a region proximate the source device 200.

At step 480, respective speakers of each of the first speaker unit, the second speaker unit, and the third speaker unit are actuated based on the synchronizing with the source, and the respectively received audio data.

FIG. 5 is a flow diagram of a method of managing an audio system. At step 510, a first power source, a second power source, and a third power source a provided to each of a first synchronous media transceiver, a second synchronous media transceiver, and a third synchronous media transceiver, respectively. For example, a rechargeable battery source or mains power supply. At step 520, a first speaker unit, a second speaker unit, and a third speaker unit are coupled to the first power source, the second power source, and the third power source, respectively. At step 530, the first synchronous media transceiver, the second synchronous media transceiver, and the third synchronous media transceiver are synchronized with a source of audio data. For example, the source of audio data may be a smartphone or audio transceiver. Further, the synchronous media transceivers may be synchronized to produce acoustic signals substantially simultaneously or may be synchronized to produce acoustic signals to produce an intended effect, such as to be received substantially simultaneously in a particular region or at a particular point. For example, the synchronous media transceivers may be synchronized to produce acoustic signals which converge substantially simultaneously on the location of the source of audio data or another tracking device.

At step 540, audio data is received by each of the first synchronous media transceiver, the second synchronous media transceiver, and the third synchronous media transceiver, for example, from the source of audio data. At step 550, a first audio channel and a second audio channel of the audio data is received at the first speaker unit via the first synchronous media transceiver. At step 560, the first audio channel and the second audio channel of the audio data is received at the second speaker unit via the second synchronous media transceiver. At step 570, the first audio channel and the second audio channel are received at the third speaker unit via the third synchronous media transceiver. At step 572, transmission of the second audio channel is selectively inhibited at the first speaker unit. At step 574, transmission of the first audio channel is selectively inhibited at the second speaker unit. For example the first speaker unit and second speaker unit may employ dedicated circuitry, such as one or more dump resistors, to attenuate, mute, or otherwise inhibit the respective audio channels from being passed on to a speaker. At step 580, respective speakers of each of the first speaker unit, the second speaker unit, and the third speaker unit are actuated based on the synchronizing with the source, and the respectively received audio data.

Thus, the disclosure provides, among other things, an audio system and various methods of managing audio systems. Various features and advantages of the disclosure are set forth in the following claims.
