[0033] Please note that the drawings of various implementation configurations are not necessarily to scale. The drawings are intended to show only typical embodiments of this disclosure and should not be considered to limit the scope of implementation configurations. In the drawings, similar numbering represents similar elements between drawings. [Modes for carrying out the invention]

[0034] This disclosure is at least in part based on the recognition that portable speakers, such as public-addressed (PA) speakers, can benefit from providing both audio monitoring capabilities and network-based output. For example, a portable speaker can be configured to enable output via a network communication link, as well as local output for monitoring purposes.

[0035] In certain embodiments, a portable loudspeaker comprises an electroacoustic transducer and a processor configured to receive a common set of audio input signals and to i) provide a first set of audio output signals to the transducer so that the first set of audio output signals functions as a monitor of the input signals, and ii) provide a second set of audio output signals via a network communication link. In some cases, the network communication-based output is referred to as a “live stream.” In certain cases, the portable loudspeaker allows for separate control of the output signals, for example, maintaining the volume or EQ level of the second set of audio output signals while the volume and / or equalization (EQ) of the first set of audio output signals is adjusted.

[0036] To achieve the functions of a portable speaker disclosed according to various implementations using conventional audio devices and systems, at least two separate audio devices connected to a computing device are required. For example, to achieve the functions of a portable loudspeaker disclosed according to various implementations, one requires, for example, a speaker that provides an audio output as a monitor, and an audio input device separate from the computing device.

[0037] In contrast to these conventional devices and systems, the loudspeakers and related approaches disclosed herein enable greater user control and device functionality. Furthermore, in some embodiments, the disclosed loudspeakers and related approaches enable the user to effectively perform for different audiences in different locations, using the ability to control output to different locations.

[0038] Commonly labeled parts in the diagrams are considered substantially equivalent for illustrative purposes, and redundant descriptions of those parts are omitted for clarity. The numerical ranges and values ​​described according to various implementations are merely examples of such ranges and values ​​and are not intended to limit these implementations. In some cases, the term “approximately” is used to modify the values, in which case these values ​​may refer to a margin of error, such as measurement error, which may range from up to 1 to 5 percent.

[0039] In some examples, PA loudspeaker systems are constructed with a specific target customer segment in mind. For example, the primary use of a PA loudspeaker system may be for a solo musician who needs an amplifier for voice or instrument (e.g., guitar or drums) to perform on the street, or for a disc jockey playing music for a small audience. In another embodiment, a PA loudspeaker system may be a general-purpose electroacoustic driver for amplifying sound, e.g., voice and / or instrument, in a classroom, a karaoke event at home, or other event involving a small group of people. In yet another embodiment, a PA loudspeaker system may be required for a larger audience, such as an auditorium. While certain embodiments of loudspeakers, such as PA loudspeakers, are described herein, additional features of such loudspeakers are also described and illustrated in U.S. Patent No. 10,555,101 (filed April 2, 2019) and U.S. Patent No. 10,524,042 (filed June 27, 2017), each of which is incorporated in whole by reference.

[0040] As shown in Figures 1A to 1C, the portable motorized loudspeaker (e.g., a PA speaker system) 10 may include an enclosure 22 (also called a housing or cabinet) having a top 51, a base 52, and a number of sides extending between the top 51 and the base 52. For example, as shown in Figures 1A to 1C, the sides may include a first side 53, a second side 54, a third side 55, a fourth side 61, a fifth side 62, a sixth side 63, and a seventh side 64. Each side extends along a common extending direction in the periphery between the top 51 and the base 52 to form the interior of the enclosure 22, where a series of mounted transducers are arranged, for example, as shown in Figure 3. In other embodiments, the enclosure 22 may have a different number of sides having varying widths or other dimensions, for example, fewer than or more than seven sides. The enclosure 22 is configured to be oriented vertically, horizontally, or diagonally, for example, tangentially or non-vertically with respect to the ground on which the loudspeaker 10 is placed.

[0041] The upper section 51 may include a plurality of inclined wall sections 121, 122, 123, 124, 125, 126, and 127, each of which inclines, tapers, or slopes from the bottom region of the upper section 51 that abuts the side surface towards the upper region, providing robustness and portability to the loudspeaker 10. Each upper wall section 121 to 127 has an upper horizontal boundary section 131, a bottom vertical boundary section 132, and an inclined or sloped section 133 extending between the upper section 131 and the bottom section 132. Therefore, the periphery of the bottom region of the upper section 51, formed by the bottom section 132 of the upper wall sections 121 to 127, may include a lip and thus may have larger parameters than the periphery of the upper region formed by the upper horizontal boundary section 131. The lip formed by the vertical bottom portion 132 of the upper wall portions 121-127 of the upper part 51 of the enclosure 22 may also have a width greater than the width of the portion formed by the sides 53, 54, 55, 61, 62, 63, and 64 of the enclosure 22.

[0042] The upper regions of the combined wall sections 121-127 may include a horizontal upper boundary forming a cavity or recess within the upper section 51, where the handle 72 may be positioned. The handle 72 can enable the portable loudspeaker 10 to be easily carried and transported with one hand.

[0043] The upper section 51 may have a pentagonal shape formed from the walls 121, 123, 124, 125, and 126. However, the walls may be of different lengths, and other walls may extend between the sides of the five pentagons, so the upper section 51 does not have to be a perfect pentagon (i.e., all five sides are of the same length). For example, as shown, the upper section may include a wall 122 between walls 121 and 123 and a wall 127 between walls 121 and 126, which would otherwise provide bevels or cutoffs in the areas that are the corners between walls 121 and 123 and between walls 121 and 126, respectively. In some embodiments, the upper walls 121-127 and the corners formed between them may be aligned along a common extending direction with the sides 53, 54, 55, 61, 62, 63, and 64, and the corners between them. For example, the corner region C' between wall portions 121 and 122 may extend along the same axis as the corner region C'' between sides 53 and 61, as shown in Figure 1A. In some embodiments, the base side, e.g., side 142, may have the same width as the enclosure side, e.g., 61. In other embodiments, the width of the base side may differ from the width of the corresponding enclosure surface.

[0044] The base 52 of the enclosure 22, opposite to the upper 51, includes sides extending at a predetermined angle, for example, 30 degrees, from the wall portions 141-147, or from the flat bottom portion 66 and the inclined bottom portion 67 of the base 52. The flat bottom portion 66 is coupled to, integrated with, or otherwise aligned with the sides 52, 53, and 54. The inclined bottom portion 67 is coupled to, integrated with, or otherwise aligned with the sides 63 and 64, each having a tapered surface that allows for the tapering of the bottom portion 67.

[0045] The base walls 141-147 of the base may include a first portion that slopes, tapers, or inclins from the bottom surfaces 66, 67, and a second portion that extends vertically along a parallel plane identical to or parallel to the corresponding side wall. The combined first base wall forms a boundary having parameters smaller than those of the second base wall. The boundary formed from the second base wall may include a lip that is wider than the outer circumferential surface of the enclosure 22 formed by the sides 53, 54, 55, 61, 62, 63, and 64.

[0046] Therefore, each of the upper 51 and the bottom 52 may have a width, contour, perimeter, or related dimensions greater than the width, contour, perimeter, or related dimensions of the peripheral side wall region formed by the sides 53, 54, 55, 61, 62, 63, and 64. As a result, part or all of the sides are recessed relative to the upper 51 and the base 52, preventing elements from the walls, i.e., control elements 24, handles 72, etc., from protruding beyond the outermost surfaces of the upper 51 and the base 52, and thus allowing the walls of the upper 51 and the base 52 to be positioned on a flat surface without interference from such elements.

[0047] In some embodiments, the enclosure 22 may be formed and molded from a single material such that the upper 51 and base 52 are integrated with or incorporated with at least some of the sides, for example, to form a single piece. In some embodiments, all sides except the first side 53 are integrated with the upper 51 and base 52, for example, as shown in Figure 3. In some embodiments, one or more panels may be placed on top of the enclosure 22, with at least one panel forming or covering one of the sides. For example, a front grille, screen, or panel 71 may form the first side 53, or be placed on top of another layer of material forming the first side 53, or simply cover the opening of the enclosure. In some embodiments, the front grille 71 extends from the first surface 53 to at least a portion of the adjacent sides 62, 62, 54, and / or 55. In other embodiments, instead of a frame, the panels forming the sides are directly joined to each other to form a perimeter around the interior of the enclosure 22.

[0048] In some embodiments, as shown in Figure 3, the electroacoustic transducer is arranged to provide an audio output. For example, a horn-type woofer 82 and tweeters 84A-84C (generally 84) may be arranged to output sound waves from the first side 53 through the front grille 71. Behind the front grille 71, there may also be two or more acoustic ports 92A, 92B (generally 92) to allow air and / or sound to flow through the inside of the enclosure 22, for example, behind the woofer 82. In some embodiments, as shown in Figure 3, a sub-enclosure 90 may be coupled to the system frame to receive and hold the woofer 82, tweeter 84, and acoustic ports 92 in place. Multiple panels and / or sides, for example sides 53, 61, and 62, may be arranged to cover the sub-enclosure 90.

[0049] Figure 4 shows one of the sides (e.g., side 63) that includes one or more control elements 24, such as interfaces, connectors, knobs, and switches. In certain implementations, the control elements 24 can be located on the same side of the speaker 10, e.g., side 63. In other implementations, the control elements 24 can be distributed across two or more surfaces of the enclosure 22. Various additional embodiments of the loudspeaker 10 are described in the following sections, and their features can be implemented separately or in any combination that is technically feasible.

[0050] Detachable wireless transmitters (multiple units possible)

[0051] Figure 5 is a system diagram showing the signal flow paths to and from the loudspeaker 10 in various implementation configurations. In a particular case, the signal flow path shows the flow of audio signals and / or control signals to and from the loudspeaker 10, and / or between components contained in the enclosure 22. Specific control components are not shown but can be deployed similarly to those described in U.S. Patent No. 10,555,101. For example, the loudspeaker 10 may include one or more orientation sensors (e.g., an inertial measurement unit, magnetometer / gyroscope / accelerometer, etc.) to detect changes in the orientation of the loudspeaker 10 and adjust the equalization settings of the audio output based on the detected changes in orientation.

[0052] In various implementations, the loudspeaker 10 includes a processor 100 (e.g., a system processor which may include one or more microcontrollers) coupled with an audio input module 110 for receiving audio input signals from one or more source devices. In various implementations, the audio input module 110 may include an audio processor module (not shown) for communicating with the system processor 100. In certain implementations, the audio input module 110 may include a wireless communication module, such as a Bluetooth or BLE module, for communicating with one or more devices via a wireless communication protocol. The processor 100 may be configured to control amplifier inputs and outputs, including sensor inputs, outputs to fans and other temperature control components, and inputs / outputs to driver (converter) connectors such as low-frequency, medium-frequency, and high-frequency driver outputs. The processor 100 may also be configured to send and receive audio and control signals, for example, via the amplifier module connector.

[0053] In certain cases, the audio input module 110 is configured to receive audio input signals from two or more source devices, which may include source devices of different types. The loudspeaker 10 is shown with at least one input channel (two shown as 120A and 120B) for receiving a wired audio input connection in the enclosure 22. Corresponding input connectors 130A and 130B for channels 120A and 120B are shown in Figure 4. In addition, as shown in Figures 4 and 5, the loudspeaker 10 may further include at least one wireless transmitter 140 (two transmitters 140A and 140B are shown) that is detachably housed in the enclosure 22 and communicates with corresponding wireless input channels 150 (an example of two input channels 150A and 150B is shown in Figure 5) for receiving audio input from source devices (e.g., musical instruments, microphones, etc.). In a specific implementation, each wireless input channel 150 corresponds to input channels 120A and 120B for receiving wired input connections (for example, in connectors 130A and 130B). That is, the loudspeaker 10 allows the user to connect a source device wirelessly or via a wired connection to the same input channels (e.g., channel 1, channel 2, etc.). In the example shown in Figures 4 and 5, two wireless transmitters 140A and 140B are shown, corresponding to separate wireless input channels 150A and 150B, and enabling separate wireless connections between the source device and channels 150A and 150B.

[0054] Figure 5 shows additional components within the loudspeaker circuit for performing audio and / or control processing, including, for example, an analog-to-digital converter (ADC) 152 and stereo digital-to-analog converters 154A, 154B, and 154C. Specific data flow and signal flow paths are shown for illustrative purposes only and are not intended to limit various implementations. In specific cases, wireless connection flow paths are contrasted with wired connection flow paths by the term "wireless".

[0055] Figure 6 is an enlarged view showing a dock(s) 160 housing transmitter(s) 140 with the transmitter(s) 140 detached. In various configurations, the transmitter(s) 140 are configured to mechanically engage and disengage from the loudspeaker(s) 10 in the dock(s) 160. According to a particular configuration, the dock(s) 160 has a depth greater than its width or height, allowing it to accommodate connectors for each transmitter(s) 140. In certain cases, the transmitter(s) 140 are detachable from the loudspeaker(s) 10 in the dock(s) 160 and attachable to the loudspeaker(s) 10 without tools or other external devices. For example, the transmitter(s) 140 can be configured to connect to the dock(s) 160 via interlocking arms(s) or hooks(s), spring mounts, pressure-fit connectors, etc. In these cases, the user can manually connect and disconnect the transmitter(s) 140 from the loudspeaker(s) 10.

[0056] Figure 7 is a side view of a set of transmitters 140 removed from dock 160. Figure 8 is a view of the end face of transmitter 140 in Figure 7. Referring to Figures 6 to 8, the transmitters 140 can be configured to slide in and out of dock 160 on one or more rails 170 or other guide members within dock 160. In some cases, each dock 160 has a pair of rails 170 for aligning the corresponding transmitters 140 when docked. In certain implementations, as shown in Figure 8, the transmitters 140 may include recesses 180 (two shown in this embodiment) that complement the rails 170. In other cases, the recesses may be located within dock 160 and the rails (or similar projections) may be located on the transmitters 140. That is, any form of complementary alignment function can be utilized to align the transmitters 140 within dock 160. In additional implementations, the transmitters 140 include a flexible material 190 at the interface with dock 160. This flexible material 190 may be different from the harder material placed in other parts of the transmitter 140, and may allow for a desirable consistent mating between the body of the transmitter 140 and the dock 160.

[0057] In some implementations, each transmitter 140 may include a command button 195 for controlling one or more functions of the transmitter 140. For example, as shown in Figure 7, the transmitter 140 may include a power button 200 for turning the transmitter 140 on and / or off. In some implementations, as optionally indicated by dashed lines, the transmitter 140 may also include a mute button 210 for muting the output from the transmitter 140.

[0058] In certain implementations, as shown in Figure 7, one of the transmitters 140A includes a chip-sleeve (TS) audio connector 220 for coupling with a source device. As illustrated, the TS audio connector 220 is configured to be nested within the body of the transmitter 140A or otherwise housed, which protects the connector 220 while allowing docking and detachment from the dock(s) 160. Figure 7 shows the connector in an intermediate state where a portion of the TS audio connector 220 is located outside the body of the transmitter 140. It should be understood that in certain implementations, the TS audio connector 220 may be replaced with a chip-ring sleeve (TRS) audio connector. The TS audio connector 220 can be configured to couple with a source device such as an electric musical instrument (e.g., guitar, keyboard, etc.) or any other output device having a corresponding TS mating connection. In additional implementations, one of the transmitters 140B includes an XLR audio connector 230 for coupling with a source device. The XLR audio connector 230 may be configured to connect to a source device such as a microphone or other line-level source(s). In various implementations, each dock 160 is configured to accept one of the transmitters 140. That is, the first dock 160A may be configured to accept either transmitter 140A or transmitter 140B, and the second dock 160B may be configured to accept either transmitter 140A or transmitter 140B. Furthermore, it should be understood that the input connector 130 may be configured to make physical connections to TS, TRS, and / or XLR audio connectors.

[0059] As described herein, a dock(s) 160 may provide both physical and electrical connections to a transmitter(s) 140 for storage, power supply / charging, and communication. For example, referring to Figures 7 and 8, each dock 160 may include an electrical and / or data connector 240 for coupling with a corresponding connector 240' on the transmitter 140 (shown as being located inside the main body). In certain cases, the electrical and / or data connector 240 may include a USB connector. In certain embodiments, the connector 240 (e.g., a USB connector, or a variation thereof such as a USB-C connector) enables software updates of the transmitter 140 or debug accessory mode (DAM) operation in the transmitter 140.

[0060] The dock 160 may also include a spring coupling 250 and magnets 260 (or more magnets). In certain cases, the spring coupling 250 allows the user to push to engage and / or push to disengage, respectively, thereby coupling the transmitter 140 to and disengaging it from the dock 160. In certain cases, when the transmitter 140 is docked, the outer surface of the transmitter 140 is substantially coplanar with the outer surface of the enclosure 22. This position can be maintained by the spring coupling and magnets 260. In certain cases, the spring coupling 250 allows the transmitter 140 to be released so that the user can grasp the transmitter 140 and remove it from the dock 160. In certain cases, the connector 240 (e.g., a USB connector) is maintained in an intermediate position, and as a result, the transmitter 140 remains connected to the magnets 260 and connector 240 even after the spring coupling 250 has been released. In other words, a force greater than the spring force of the coupling portion 250 is required to overcome the coupling between the transmitter 140 and the connector 240 and magnet 260. In this sense, the connector (e.g., a USB connector) 240 has the minimum holding force necessary to maintain the data connection with the loudspeaker 10.

[0061] In some cases, each wireless transmitter 140 has a battery and is configured to begin charging the battery in response to being engaged with one of the docks 160. For example, in response to the detection of a connection (e.g., a USB connection) at the connector 240, the processor in the loudspeaker 10 is configured to begin charging the transmitter 140.

[0062] In additional implementations, each transmitter 140 is configured to connect a source device (e.g., a musical instrument, microphone, etc.) to a corresponding wireless input channel (e.g., channel 1, channel 2, etc.) in response to detecting a connection with a source device. In certain implementations, when a user connects transmitter 140 to a source device, transmitter 140 automatically pairs the source device with an input channel (e.g., channel 1, channel 2, etc.). In certain implementations, if transmitter 140 is in a sleep or standby state before connecting to a source device, transmitter 140 is configured to wake up in response to detecting a connection with a source device. In certain cases, a transmitter 140 in a sleep or standby state wakes up in response to detecting a connection and then connects the source device to an input channel.

[0063] As described herein, in a scenario where the loudspeaker 10 has multiple transmitters 140 for transmitting signals to multiple input channels (e.g., channel 1, channel 2), the processor in the loudspeaker 10 is configured to receive audio input from each of the radio input channels. In certain cases, each radio input channel has a separate radio antenna. In some cases, the separate antennas are dedicated to the corresponding radio input channel. Figure 9 shows a partial perspective cutaway of the loudspeaker 10, illustrating an example of two separate radio antennas 300A, 300B (e.g., radio frequency (RF) antennas) along with a Bluetooth (BT) antenna 310. In certain implementations, each antenna 300A, 300B is positioned and oriented to provide substantially uniform omnidirectional sensitivity along a plane to radio signals from the corresponding radio transmitters 140. In other words, along a given plane, such as a height relative to the ground or floor, each of the antennas 300A and 300B exhibits substantially uniform sensitivity to the radio signal from the corresponding transmitter 140 in all directions. This allows the user to connect the radio transmitter 140 for any channel to a source device (e.g., a microphone, musical instrument, etc.) and move around the loudspeaker 10 in the plane without significant differences in radio signal quality. In a particular case, as described herein, the loudspeaker 10 is configured to operate in multiple orientations, and each antenna 300A and 300B maintains substantially uniform omnidirectional sensitivity along the plane to the radio signal from the corresponding transmitter (e.g., transmitter 140A, transmitter 140B), regardless of the orientation of the loudspeaker 10.

[0064] In certain implementations, the audio input to the loudspeaker 10 can be controlled by one or more control elements 24 (Figure 4), such as via a command interface, GUI, dial, or buttons. In additional implementations, the audio input to the loudspeaker 10 can be controlled by commands from an application running on a connected smart device. That is, the user can control the selection of audio inputs (e.g., from a Bluetooth device, transmitter 140A, transmitter 140B, etc.) using commands from an application running on a connected smart device such as a smartphone, tablet, or dedicated controller.

[0065] In additional implementations, the loudspeaker 10 is configured to wirelessly connect to a first additional portable speaker via one of the wireless input channels. For example, the loudspeaker 10 can connect to an additional similar loudspeaker via a Bluetooth connection (e.g., via the BT antenna 310) or via another wireless communication protocol (e.g., Wi-Fi). In specific cases of these, the loudspeaker 10 can provide audio output to the first additional portable speaker via the wireless connection.

[0066] In further implementations, the loudspeaker 10 is configured to wirelessly connect to a second additional portable speaker (for example, a speaker similar to the loudspeaker 10) via a wireless input channel and a line-out connection in the second additional portable speaker. In these cases, the loudspeaker 10 is configured to receive audio input from the second additional portable speaker via one of the wireless transmitters 140 coupled to the line-out connector 350 (Figure 4) to form a wireless daisy-chain between the loudspeakers 10.

[0067] As referred to herein, the loudspeaker 10 is configured for both wired (wired) and portable (e.g., battery-powered) use. That is, as shown in Figure 4, the enclosure 22 may include a wired power connector 360 for charging an onboard battery (housed in the enclosure 22) that can power a converter(s), processor(s), audio input module(s), etc. The wired power connector 360 may also provide power to charge the wireless transmitter 140, including onboard power storage (e.g., battery(s)), as described herein. In various implementations, the battery(s) in the loudspeaker 10 and / or transmitter 140 are rechargeable and / or replaceable.

[0068] Automatic detection of input channels

[0069] In certain implementations, the loudspeaker 10 is configured to automatically detect the input channel and adjust the audio input signal accordingly. In certain cases, the processor 100 is configured to adjust the audio signals received from the wired input connection 130 and / or the wireless transmitter 140 based on one or more of the connection status or connection order. Figure 10 illustrates how the processor 100 manages input connections in various implementations. For example, in certain cases, the processor 100 is configured to detect the status of the wired audio input connection at connector 130 (process P1) and the wireless connection with transmitter 140 (decision D1). If the wireless connection precedes the wired connection at connector 130 (Yes to D1), the processor 100 adjusts the audio signal from the wired connector 130 (process P2). If the wireless connection does not precede the wired connection (No to D1), the processor 100 outputs the audio input from the wired connector 130 as the primary audio (process P3).

[0070] In certain implementations, decision D1 (the step of detecting the state of the wireless connection with the transmitter) includes checking whether the wireless transmitter 140 is present in the corresponding dock 160 before determining whether the audio input from the source device is detected via the wireless connection 150. In some of these cases, the processor 100 can first determine whether the wireless transmitter 140 is powered on, and if so, whether the transmitter 140 is paired with the corresponding channel (e.g., channel 1 or channel 2). In further cases, the processor 100 determines whether the audio input is received via the paired wireless transmitter 140. According to some implementations, if the wireless transmitter 140 is powered on and paired with the corresponding input channel (e.g., channel 1 or channel 2), the loudspeaker 10 adjusts only the audio signal from the wired connector 130 (process P2). In a further implementation, the loudspeaker 10 adjusts only the audio signal from the wired connector 130 if the wireless transmitter 140 is paired and an audio input is being received from the transmitter 140 (process P2). If the processor 100 determines that the transmitter 140 is powered on but not paired or is not providing an audio input, the processor 100 prioritizes the wired connection and outputs the audio input from the connector 130 as the primary audio (process P3).

[0071] In certain embodiments, the step of adjusting the audio signal in process P2 includes switching the input channel 120 for the wired connector 130 to the effects loop. In certain cases of these embodiments, the step of adjusting the audio signal in process P2 includes adjusting the pre-amplification order of the audio signal (from the wired connector 130) before providing an audio output, for example by prioritizing the amplification of the radio signal from the transmitter 140 over the signal from the wired connector 130. In various implementations, the audio input from a source device (e.g., a microphone, instrument, additional connected speaker, or audio gateway) received via the wired connector 130 is received as a digital audio input and converted to an analog audio signal. In certain cases, the transmitter 140 transmits at a frequency of approximately 2.4 gigahertz (GHz).

[0072] Returning to Figure 4, in a particular implementation, the processor 100 is configured to select an audio input (e.g., between transmitters 140A, 140B and connector 130) based on commands from an application running on a connected smart device 400 (e.g., a smartphone, smartwatch, tablet, controller, etc.). In a particular case, the smart device 400 runs or otherwise accesses a program (e.g., an application) configured to control the functions of the loudspeaker 10, such as input selection, volume and / or equalization settings adjustment, and power settings (e.g., on / off / standby). In a particular case, the functions of the application may be run on a dedicated controller in addition to or instead of the smart device 400.

[0073] As further shown in Figure 4, the loudspeaker 10 may include a wired power connector 360 for charging the onboard battery and supplying power to the loudspeaker 10 (for example, for connecting to an external power source).

[0074] Dynamic display characteristics

[0075] Figure 11 shows an enlarged view of a display 500 that may include one or more control elements 24 as shown in Figure 4. The display 500 can be placed on any surface of the loudspeaker 10 and, in certain cases, adjacent to the control elements 24. An example of a control element 24 shown in Figure 11 includes a volume control unit (e.g., a knob) 505 for each of a plurality of inputs (e.g., channel 1, channel 2, and BT input). In certain implementations, the display 500 may include a plurality of sub-displays 510A, 510B, 510C. One or more embodiments of the display 500 may include digital display elements such as digital screens or windows, as shown in, for example, sub-displays 510A, 510B, 510C. In some cases, the sub-displays include organic light-emitting diodes (oLEDs).

[0076] In various implementations, as shown in Figures 11 and 12, the orientation of the display 500 is configured to adjust between a first orientation (Figure 11) and a second orientation (Figure 12) in response to detecting a change in the orientation of the loudspeaker 10. That is, when the orientation of the loudspeaker is adjusted between two or more orientations, the display 500 (including, for example, one or more sub-displays 510A, 510B, 510C) is adjusted between at least two orientations. Figure 11 shows the first orientation of the display 500 relative to the loudspeaker 10, and Figure 12 shows the second orientation of the display 500 relative to the loudspeaker 10. In certain implementations, the orientation of the display 500 is intended to be easily identifiable to the user in a given loudspeaker orientation, and can be read, for example, from left-right and vertical orientations. As described herein, the loudspeaker 10 can be configured to operate in at least three distinct predetermined playback orientations (for example, as shown in Figures 1A, 1B, and 1C). In certain embodiments, a first orientation of the display 500 corresponds to two or more of the playback orientations (for example, as shown in Figures 1A and 1B), and a second orientation of the display 500 corresponds to a distinct playback orientation (for example, in Figure 1C).

[0077] As described herein, the processor 100 is coupled with an orientation sensor 520 (Figure 5) for indicating the orientation of the loudspeaker 10. The orientation sensor 520 may include a gyroscope, magnetometer, accelerometer, and / or inertial measuring unit (IMU) and may be configured to provide the processor 100 with data regarding the change in orientation in response to the detection of a change, such as being corrected by a threshold and / or hysteresis coefficient. In a particular example as shown in Figures 11 and 12, the display 500 includes a set of visual signal indicators 530 corresponding to the input channels (e.g., wired channel connections 130A, 130B and / or wireless connections 150A, 150B). As shown in Figures 11 and 12, the visual signal indicators 530 may provide visual feedback regarding the signals received in each of the input channels (e.g., via wired connections 130A, 130B and / or wireless connections 150A, 150B). In one embodiment, as shown in the enlarged view of the visual signal indicator 530 in Figure 13, each of the visual signal indicators 530 has a low-signal end 600 and a high-signal end 610 extending between an input channel (connector) 130A, 130B or dock 160A, 160B and a corresponding display screen 510A, 510B associated with one of the channels. According to some implementations, each visual signal indicator 530 is configured to show one or more of the following: i) no signal (e.g., no fill as shown in Ch.2), ii) sufficient signal (e.g., green as shown in Ch.1), or iii) clipping (e.g., inconsistent signal or high signal level, sampled at intervals of up to 50 ms and shown in red as shown in the BT channel, for example). In certain cases, for example, when the loudspeaker 10 is oriented upright (Figures 12 and 13), the visual signal indicator 530 extends from the lower signal end 600 on the left side of the display 500 to the higher signal end 610 on the right side of the display 500.

[0078] In additional implementations, the display 500 further includes a series of visual battery level indicators 620 (Figures 11 and 12) associated with each wireless input channel 150 and corresponding to each of the detachably housed wireless transmitters 140. In certain cases, the battery level indicators 620 may indicate (e.g., in percentage, level, and / or time) the remaining battery level of a transmitter 140 that is not present in the corresponding dock 160. In addition, the battery level indicators 620 may display an indicator that the battery is charging and / or (when applicable) fully charged when the transmitter 140 is in a given dock 160. The battery level indicators 620 may also indicate the battery level of a connected Bluetooth device, connected via the BT channels shown in Figures 11 to 13.

[0079] In certain implementations, the processor 100 is further configured to communicate with an application running on the smart device 400 (Figure 4) to provide additional visual or audible signal indicators. For example, the visual signal indicator on the smart device 400 may be displayed, for example, progressively via an application interface to provide the user with information about the signals received through the input channels. The visual signal level indicator on the smart device 400 may be in a similar format and / or style to the visual signal indicator 530 on the display of the loudspeaker 10, or it may be in a different format and / or style. In various implementations, the visual signal level indicator on the smart device 400 is part of a digital display. Furthermore, the application may initiate an audible signal indicator, such as an audible beep, chime or tone, or clipping sound, via the speaker of the smart device 400 to indicate the characteristics of the signals received on the channel(s). Furthermore, the visual and / or audible signal indicators may include information about adjustments(s) suggested to improve the signals received by the speaker 10. For example, the suggested adjustments may include a message (e.g., visual and / or audible) suggesting that the user adjust a physical connection (e.g., in a wired connector 130) or move the transmitter 140 closer to the speaker 10 (e.g., in the case of a wireless transmitter 140).

[0080] In additional implementations, the processor 100 is configured to provide an error indicator on the display 500 in response to detecting that the speaker 10 is oriented incorrectly for a given playback orientation. For example, the processor 100 may provide an error indicator (e.g., a visual indicator on the display 500 and / or an audible indicator via the transducer(s) 82, 84) indicating that the speaker 10 is tilted or upside down. In certain implementations, a tilted arrangement is indicated by the speaker 10 being between a given playback orientation or in an unstable arrangement. In additional implementations, a tilted arrangement is defined by the speaker 10 being in an orientation other than the three predefined orientations shown in Figures 1A, 1B, and 1C. An upside-down orientation can be defined as any arrangement in which the top surface (e.g., top 51) of the speaker 10 is below the bottom surface (e.g., bottom 52).

[0081] Returning to Figures 11 and 12, in some examples, the display 500 may include three separate sub-displays 510A, 510B, and 510C, each associated with an operable button, knob, switch, etc. In some cases, the operable button includes a control unit 505. Although the button(s) 505 are shown as separate from the associated sub-display(s) 510, in certain implementations, the sub-displays 510 may receive push-button commands in addition to, or instead of, the button(s) 505. That is, the display(s) 510 may include a touch interface (e.g., a capacitive touch interface) for receiving touch commands from the user. In any case, the button(s) 505 (and / or the display(s) 510) may be configured to receive one or more commands, and in certain cases, a long-press command on a given button(s) 505 presents a configuration menu on the associated display(s) 510. The configuration menu may include configuration selection and / or adjustment options for multiple loudspeaker configurations, such as a battery mode (e.g., low power mode), settings (e.g., audio settings such as equalization, or sleep timer settings), and / or a shutdown menu that allows shutting down the loudspeaker 10. In certain implementations, as shown in Figure 4, the display 500 further includes tone matching preset switches 630 for enabling tone matching for each of the input channels, including the radio channel input from the transmitter 140.

[0082] Audio monitoring and network communication links

[0083] In certain implementations, the loudspeaker 10 is configured to enable audio monitoring and / or network communication functions, as described herein. For example, returning to Figure 5, in a particular case, the processor 100 (related to the audio input module 110) is configured to receive audio input signals from, for example, one or more of the input channels, process the input signals, and provide audio output signals to, for example, the converters 82, 84 via an amplifier (To Amp) and to a network communication link (e.g., To USB, such as a USB-C type connector / port). In certain implementations, the USB link (e.g., To USB) includes a USB audio link. In various implementations, network communication is facilitated by a To USB connection, so the network communication link may also be called a USB audio link. In certain cases, the input signals are provided by one of the inserted mode channels 120 of the wireless channel 150, or by a Bluetooth® (BT) channel connection (Figure 12), as described according to the various implementations herein. In certain cases, the processor 100 is configured to provide a first set of audio output signals to the converters 82, 84 and a second set of audio output signals to the USB audio link (or network communication link, To USB). Processing the audio input signals as described herein may include adjusting at least one of the relative signal levels, equalization, or reverb of any one or more of the audio input signals.

[0084] In certain implementations, the first audio output signal set functions as a monitor for audio input signals output locally by, for example, the converters 82, 84 of the loudspeaker 10. In these cases, the second audio output signal set is provided to a network communication link, for example, a USB audio link connection to another device with network connectivity. In some cases, the processor 100 allows the user to provide synchronized monitoring and local audio output while streaming or recording audio output over the network communication link (USB audio link).

[0085] In certain embodiments, as shown in system 700 of Figure 14, the loudspeaker 10 is coupled to a network interface device 710, for example, via a network communication link 720 (e.g., a USB audio link connector). In some cases, the network interface device 710 includes a computing device such as a personal computer, tablet, or smartphone. In certain cases, the network interface device 710 is coupled to a network such as a Wi-Fi network, a cellular network, or other communication network including, for example, an internet connection. In certain embodiments, the network interface device 710 includes a computing device having a processor and memory, and may be coupled to the loudspeaker via a wired or wireless connection (or link) 720 (indicated by a virtual line). In certain cases, the computing (network interface) device 710 includes a digital audio workstation (DAW) 730, which may include electronic devices or application software used to record, edit, and generate audio files. In certain implementations, the DAW 730 includes an interface (e.g., a display and / or control unit) for enabling a user 740 to control a second set of output signals. In certain cases, the functionality of the DAW 730 can be integrated into the processor 100 within the loudspeaker 10, for example, as a software stack.

[0086] In the illustrative depiction of Figure 14, user 740 is shown with an audio input device 750, such as a microphone, which may have a wired or wireless connection to the loudspeaker 10. In a particular case, the audio input device 750 provides audio input signals to the loudspeaker 10, for example, via channels 120, 150 (Figure 5). It is understood that multiple audio devices, such as two or more instruments, a mixing device, a digital audio output device, a BT connection device, etc., may provide input to the loudspeaker 10. As described according to the various implementations herein, wireless and / or wired inputs are provided to the loudspeaker 10 and may be mixed and / or prioritized according to one or more rules.

[0087] Returning to the example in Figure 14, the loudspeaker 10 (for example, the processor 100 in Figure 5) is configured to receive audio input signals from the audio input device 750 and / or the user's smart device 760, process those input signals, and provide audio output signals. In a particular case, the loudspeaker 10 includes an amplifier configured to provide amplified audio signals from the audio input signals and / or audio output signals to, for example, converters 82, 84. In a particular case, a first set of audio output signals is output by the converters 82, 84 in the loudspeaker. In this case, the first set of audio output signals functions as a monitor of the input signals (for example, from the audio input device 750). Furthermore, the processor 100 is configured to provide a second set of audio output signals to a computing device 710, for example, via link 720. In certain cases, the second audio output signal set is transmitted via the network communication link 720 to at least one of the following: the DAW 730, a live stream, or a network-connected recording device. According to various implementations, the first and second audio output signal sets are provided (for example, as outputs in the converters 82, 84) and output to the computing device 710 almost simultaneously.

[0088] In certain embodiments, the first and second audio output signal sets enable user 740 to provide output to two devices (loudspeaker 10 and computing device 710) from a common audio input(s) nearly simultaneously. For example, user 740 can use loudspeaker 10 as an audio monitor (or local output device) and a network link to provide a "live stream" of the audio input (e.g., performance) nearly simultaneously.

[0089] Figure 15 shows an example of a simplified diagram of the control elements 24 in Figure 4, including interfaces, connectors, knobs, switches, etc. Figure 15 also shows a set of adjustment control units (e.g., knobs) 505a, 505b, and 505c on the user interface 800. The adjustment control units 505a, 505b, and 505c can correspond to three separate input channels (channel 1, channel 2, and channel 3 (BT)) available to the loudspeaker 10. In some implementations, it is understood that a similar user interface 800 including one or more of the control elements 24 may be replicated (or mirrored) on a digital display such as on a computing device 710 or a smart device 760. In the exemplary depiction of Figure 15, the multiple adjustment control units 505 are configured to allow adjustment of channel audio (e.g., channel 1, channel 2, and channel 3 (BT)) and / or access to additional functions of the loudspeaker 10. In certain embodiments, the adjustment control unit 505 enables adjustment of the output volume of one or more channels (e.g., channel 1, channel 2, channel 3 (BT)). In certain implementations, the adjustment control units 505a, 505b, and 505c enable adjustment of the output volume of channel 1, channel 2, and channel 3, respectively. In one embodiment, the adjustment control unit 505c enables the selection of one or more operating modes, including a "livestream" mode, thereby enabling a second set of audio output signals to be provided to another device (e.g., via USB, computing device 710). According to certain implementations, activating the adjustment control unit 505c triggers one or more additional interface displays 810, 820, which may be provided on interface 800 and / or on connected devices such as computing device 710 or another smart device running a control application for the loudspeaker 10. In some cases, the additional interface displays 810, 820 provide commands and / or mode selection for multi-mode operation of the loudspeaker 10.

[0090] In one embodiment, the loudspeaker 10 is configured to operate in a first mode, which includes outputting a first set of audio output signals. In some cases, this first mode is the default operating mode of the loudspeaker 10. In additional implementations, a second mode (e.g., live stream) includes outputting both the first set of audio output signals (e.g., as monitor outputs to converters 82, 84) and a second set of audio output signals (e.g., to computing device 710 and / or additional network-connected devices). In certain implementations, switching between the first and second modes includes multimodal adjustment in interface 800. In some embodiments, multimodal adjustment includes long-press commands, press-and-turn commands, etc. Figure 15 shows an example of a long-press command instruction in interfaces 810, 820 to enable selection of a second or subsequent operating mode (e.g., live stream). Figures 16 and 17 illustrate the progression of selecting a second or subsequent operating mode (e.g., livestream) via interfaces 810 and 820 using rotation of the adjustment control unit 505c. In this exemplary implementation, a single adjustment control unit (e.g., 505c) can be used to switch the operating mode at interface 800.

[0091] In some cases, within a given mode, for example, when both a first audio output signal set and a second audio output signal set are provided (also referred to herein as a live stream), the processor 100 enables operation in at least two (sub)modes, including a first mode in which the volume level of the first audio output signal set (to the Amp) and the volume level of the second audio output signal set (to the USB) are coupled, and a second mode in which the volume level of the first audio output signal set (to the Amp) and the volume level of the second audio output signal set (to the USB) are uncoupled. That is, in certain implementations, the processor 100 enables independent adjustment of the first audio output signal set (to the Amp) and the second audio output signal set (to the USB). For example, the processor 100 may be configured to enable separate volume control of the first audio output signal set (to the Amp) and the second audio output signal set (to the USB). In certain cases, separate volume control includes applying separate gains to input signals from channels 1, 2, and / or 3 (BT). For example, continuing to refer to Figure 5, the processor 100 can be configured to instruct the audio input module 110 to apply separate gains to input signals (e.g., from the insert-mode audio input via channel 120 and / or from the radio input on channel 150) to enable separate volume control of the output signal (to Amp vs. USB). An exemplary interface progression of separate volume control in livestream mode is shown in Figures 18 and 19, in which the processor 100 indicates separate interfaces 810, 820 in response to operation of the adjustment control unit 505c (e.g., long press, press and release, repeated press and release, etc.), enabling independent control of the volume of the first audio output and the second audio output, respectively. For example, interface 820 indicates a “monitor volume” control that enables independent control of the volume of the first audio output (to Amp) relative to the volume of the second audio output (to USB).Figure 19 shows additional (e.g., subsequent) operations (e.g., rotation, sliding, etc.) of the adjustment control unit 505c to adjust the volume of the first audio output (to the Amp) while maintaining the volume level of the second audio output (to the USB).

[0092] Furthermore, the processor 100 can enable separate equalization (EQ) settings and / or separate mix settings for one or both of the first audio output signal set (to the Amp) and the second audio output signal set (to the USB). In certain cases, the separate mix settings are applied to the mix of at least two inputs, e.g., channel 1, channel 2, and / or channel 3 (BT). In some cases, adjustments to the monitor volume (first audio output), EQ settings, and / or mix settings are available only on the interface 800 of the loudspeaker 10. In other cases, the monitor volume, EQ settings, and / or mix settings are adjustable via an interface on a connected smart device, such as the computing device 710.

[0093] In additional implementations, the loudspeaker 10 also includes a mixer coupled to the audio inputs (e.g., channels 120, 150, wireless channel (BT), Figure 5). In some cases, the mixer is a component within the audio input module 110 or coupled to the audio input module 110, for example, an electronic component and / or software stack. In specific cases, the audio inputs to the loudspeaker 10 may include at least two or up to three inputs from each of channels 1, 2, and 3 (BT), and the mixer is configured to mix the input signals from channels 1, 2, and 3. In some embodiments, the mixer is configured to provide a second set of audio output signals (to USB) as a dual-mono mix of multiple input channels (channel 1, channel 2). In additional implementations including a mixer, one or more adjustment control units 505 may enable adjustment of the mix. For example, during default operation (e.g., single output mode such as To Amp), the adjustment control unit 505a can control the volume of channel 1, the adjustment control unit 505b can control the volume of channel 2, and the adjustment control unit 505c can control the volume of channel 3 (BT). When the loudspeaker 10 is operating in dual output mode (e.g., live stream mode, or first audio output To Amp and second audio output To USB, respectively), the adjustment control units 505a, 505b, and 505c can enable mixer phasing and / or channel level adjustment for the corresponding channels in the dual mono mix. For example, while live stream mode is activated, the adjustment control units 505a, 505b, and 505c can enable phasing adjustment and / or channel level adjustment for each channel (e.g., channel 1, channel 2, and channel 3 (BT)) in the dual mono mix.

[0094] In certain implementations, after activating livestream mode, the loudspeaker 10 remains in that mode until a trigger is detected. The trigger can include a power cycle event, disconnection of one or more input devices, or a command received on an interface (e.g., interface 800 and / or on a connected device such as computing device 710 or smart device 760).

[0095] As described herein, the loudspeaker 10 can provide several practical and beneficial configurations for the user, including, but not limited to, the connection of wireless instruments and / or microphones, automatic channel detection and audio adjustment, dynamic display characteristics, and audio monitoring and network connectivity.
