The drawings are intended only to illustrate typical aspects of this disclosure and should not be considered as limiting the scope of the specific embodiments. In the drawings, similar numbers indicate similar elements between the figures. Detailed Implementation

[0054] This disclosure is based, at least in part, on the understanding that portable loudspeakers (such as public address (PA) loudspeakers) can benefit from both providing audio monitoring functionality and network-based output. For example, a portable loudspeaker can be configured to provide output via a network communication link as well as local output as a monitor.

[0055] In a specific example, the portable megaphone has an electroacoustic transducer and a processor configured to receive a common set of audio input signals and: i) provide a first set of audio output signals to the transducer, such that the first set of audio output signals acts 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-based output is referred to as a “live stream.” In other cases, the portable megaphone implements different controls over the output signals, for example, maintaining the volume or EQ level of the second set of audio output signals while adjusting the volume and / or equalization (EQ) of the first set of audio output signals.

[0056] To realize the functionality of the portable loudspeaker disclosed according to various specific embodiments, conventional audio equipment and systems require at least two different audio devices connected to the computing device. For example, realizing the functionality of the portable megaphone disclosed according to various specific embodiments requires, for example, a loudspeaker for providing audio output as a monitor, and a separate audio input device to the computing device.

[0057] Compared to these conventional devices and systems, the loudspeakers and related methods disclosed herein enable greater user control and device functionality. Furthermore, in some examples, the disclosed loudspeakers and related methods allow users to effectively perform for different audiences in different locations by utilizing the ability to control the output to those different locations.

[0058] For illustrative purposes, components typically labeled in the accompanying drawings are considered substantially equivalent, and redundant discussion of those components is omitted for clarity. The numerical ranges and values ​​described according to various specific embodiments are merely examples of such ranges and values ​​and are not intended to limit those embodiments. In some cases, the term "approximately" is used to modify values, and in these cases, it can refer to a margin of error (such as measurement error) in the value, which can range from a maximum of 1% to 5%.

[0059] In some examples, PA amplifier systems are constructed with specific target customer groups in mind. For instance, a primary use of a PA amplifier system might be for a solo musician requesting amplification of voice or musical sounds (e.g., guitar or drums) for a street performance, or for a DJ playing songs for a smaller audience. In another example, a PA amplifier system might be a general-purpose electroacoustic driver for amplifying sound, such as voice and / or musical sounds, in a classroom, home karaoke event, or other event involving a small group of people. In other examples, a PA amplifier system might be required for a larger audience, such as an auditorium. While specific aspects of amplifiers such as PA amplifiers are described herein, additional features of such amplifiers are also described and illustrated in U.S. Patent Nos. 10,555,101 (filed April 2, 2019) and 10,524,042 (filed June 27, 2017), each of which is incorporated herein by reference in its entirety.

[0060] like Figures 1A to 1C As shown, a portable power amplifier (e.g., a PA speaker system) 10 may include a housing 22 (also referred to as a enclosure or cabinet) having a top portion 51, a base 52, and a plurality of side surfaces extending between the top portion 51 and the base 52. For example, as Figures 1A to 1CAs shown, the side surfaces may include a first side surface 53, a second side surface 54, a third side surface 55, a fourth side surface 61, a fifth side surface 62, a sixth side surface 63, and a seventh side surface 64. Each side surface extends along a common extending direction between the top portion 51 and the periphery of the base 52 to form the interior of the housing 22, wherein a set of mounted transducers is positioned inside the housing, for example, Figure 3 As shown. In other examples, the housing 22 may have a different number of side surfaces with various widths or other dimensions, for example, fewer or more than seven side surfaces. The housing 22 is configured to be oriented vertically, horizontally, or at an angle, for example, tangent to or not perpendicular to the ground surface where the loudspeaker 10 is located.

[0061] The top portion 51 may include a plurality of slanted wall portions 121, 122, 123, 124, 125, 126, 127, each slanted wall portion slanting, tapering, or tilting from the bottom region of the adjacent side surface of the top portion 51 to the top region to achieve robustness and portability of the loudspeaker 10. Each top wall portion 121 to 127 has a top horizontal boundary portion 131, a bottom vertical boundary portion 132, and a slanted or tilted portion 133 extending between the top portion 131 and the bottom portion 132. Therefore, the periphery of the bottom region of the top portion 51 formed by the bottom portion 132 of the top wall portions 121 to 127 may include a lip and thus have a larger parameter than the periphery of the top region formed by the top horizontal boundary portion 131. The lip formed by the vertical bottom portion 132 of the top wall portions 121 to 127 of the top portion 51 of the cover 22 may also have a width greater than the width of a portion of the cover 22 formed by the side surfaces 53, 54, 55, 61, 62, 63 and 64.

[0062] The top region of the assembly wall portions 121 to 127 may include a horizontal top boundary that forms a cavity or recess in the top portion 51 in which the handle 72 can be positioned. The handle 72 allows for easy one-handed carrying and transport of the portable megaphone 10.

[0063] The top portion 51 may have a pentagonal shape formed by the wall portions 121, 123, 124, 125, and 126. However, the top portion 51 may not have an ideal pentagonal shape (i.e., all five sides have the same length) because the wall portions may have different lengths, and because other wall portions may extend between the five pentagonal sides. For example, as shown, the top portion may include a wall portion 122 between wall portions 121 and 123 and a wall portion 127 between wall portions 121 and 126, which provides bevels or cutouts at the areas that would otherwise be corners between wall portions 121 and 123 and between wall portions 121 and 126, respectively. In some examples, the corners formed by the top wall portions 121 to 127 and between them may be aligned along the same common extending direction as the side surfaces 53, 54, 55, 61, 62, 63, and 64 and the corners between them. For example, the corner region C' between wall portion 121 and wall portion 122 may extend along the same axis as the corner region C” between side surfaces 53 and 61, such as Figure 1A As shown. In some examples, the base side surface, such as side surface 142, may have the same width as the housing side surface, for example, 61. In other examples, the width of the base side surface may be different from the width of the corresponding housing surface.

[0064] The base 52 on the side of the housing 22 opposite to the top portion 51 includes wall portions 141 to 147, or side portions extending from the flat bottom surface portion 66 and the angled bottom surface portion 67 of the base 52 at a predetermined angle (e.g., 30 degrees). The flat bottom surface portion 66 is coupled to, integral with, or otherwise aligned with the side surfaces 52, 53, and 54. The angled bottom surface portion 67 is coupled to, integral with, or otherwise aligned with the side surfaces 63 and 64, each side surface having a tapered surface to allow for the taper of the bottom surface portion 67.

[0065] The base wall portions 141 to 147 of the base may include a first portion that is oblique, tapered, or inclined from the bottom surfaces 66, 67, and a second portion that extends vertically, for example, along a plane that is the same as or parallel to the corresponding sidewall. The first base wall portions are combined to form a boundary having parameters smaller than those of the boundary of the second base wall portions. For example, the boundary formed by the second base wall portions may include a lip that is wider than the peripheral outer surface of the housing 22 formed by the side surfaces 53, 54, 55, 61, 62, 63, and 64.

[0066] Therefore, the top 51 and the bottom base 52 may each have a width, circumference, perimeter, or related dimension greater than the width, circumference, perimeter, or related dimension of the peripheral sidewall region formed by the side surfaces 53, 54, 55, 61, 62, 63, and 64, such that some or all of the side surfaces are recessed relative to the top portion 51 and the base 52 to prevent elements from the wall (i.e., control element 24, handle 72, etc.) from protruding beyond the outermost surface of the top portion 51 and the base 52, thereby allowing the wall of the top portion 51 and the base 52 to be positioned on a flat surface without interference from such elements.

[0067] In some examples, the housing 22 may be formed or molded from a single material, such that the top portion 51 and the base 52 are integral or one-piece with at least some of the side surfaces, for example, in a single piece. In some examples, all side surfaces except the first side surface 53 are integral with the top portion 51 and the base 52, for example, Figure 3 As shown. In some examples, one or more panels may be positioned above the housing 22, with at least one panel forming or covering one of the side surfaces. For example, a front grille, screen, or panel 71 may form the first side surface 53, or may be positioned over another layer of material forming the first side surface 53, or may simply cover an opening in the housing. In some examples, the front grille 71 extends from the first surface 53 to at least a portion of adjacent side surfaces 62, 62, 54, and / or 55. In other examples, instead of a frame, the panels forming the side surfaces are directly coupled to each other to form a perimeter surrounding the interior of the housing 22.

[0068] In some examples, such as Figure 3 As shown, the electroacoustic transducer is positioned to provide audio output. For example, a horn-type woofer 82 and tweeters 84A to 84C (collectively, 84) can be positioned to output sound waves from the first side surface 53 and allow them to pass through the front grille 71. Also, two or more acoustic ports 92A, 92B (collectively, 92) may be included behind the front grille 71 to allow air and / or acoustic flow paths through the interior of the housing 22, for example, behind the woofer 82. In some examples, such as... Figure 3 As shown, the sub-enclosure 90 can be coupled to the system frame for receiving and holding the woofer 82, tweeter 84, and acoustic port 92 in place. Multiple panels and / or sides (e.g., side surfaces 53, 61, and 62) can be positioned above the sub-enclosure 90.

[0069] Figure 4The diagram shows one of the side surfaces (e.g., side surface 63) including one or more control elements 24 such as interfaces, connectors, knobs, switches, etc. In some embodiments, the control elements 24 may be located on the same side of the loudspeaker 10, such as side surface 63. In other embodiments, the control elements 24 may be distributed on two or more surfaces of the housing 22. The following sections describe various additional aspects of the loudspeaker 10, features of which may be implemented individually or in any technically feasible combination.

[0070] Detachable wireless transmitter Figure 5 This is a system diagram illustrating signal flow paths to and from the loudspeaker 10 according to various specific implementations. In some cases, the signal flow paths show the flow of audio and / or control signals to / from the loudspeaker 10 and / or between components housed in the housing 22. Some control components are not shown, but they may be deployed in a manner similar to that described in U.S. Patent No. 10,555,101. For example, the loudspeaker 10 may include one or more orientation sensors (e.g., inertial measurement unit, magnetometer / gyroscope / accelerometer, etc.) for detecting changes in the orientation of the loudspeaker 10 and adjusting the equalization settings of the audio output based on the detected orientation changes.

[0071] In various embodiments, the loudspeaker 10 includes a processor 100 (e.g., a system processor that may include one or more microcontrollers) coupled to an audio input module 110 for receiving audio input signals from one or more source devices. In various embodiments, the audio input module 110 may include an audio processor module (not shown) for communicating with the system processor 100. In some embodiments, the audio input module 110 may include a wireless communication module, such as a Bluetooth module or a 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 amplifier outputs, including sensor inputs, outputs to fans and other temperature control components, and inputs / outputs to driver (transducer) connectors, such as low-frequency driver outputs, intermediate-frequency driver outputs, and high-frequency driver outputs. The processor 100 is also configured to send and receive audio signals and control signals, for example, via an amplifier module connector.

[0072] 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 as including at least one input channel (two are shown, 120A and 120B), which is used to receive a hardwired audio input connector at the housing 22. Figure 4 The corresponding input connectors 130A and 130B for channels 120A and 120B are shown. Additionally, as... Figure 4 and Figure 5 As shown, the loudspeaker 10 may also include at least one wireless transmitter 140 (an example of two transmitters 140A, 140B is shown), which is detachably housed in the housing 22 and connected to a corresponding wireless input channel 150. Figure 5 An example is shown where two input channels 150A and 150B communicate, with the corresponding wireless input channels used to receive audio input from a source device (e.g., an instrument, microphone, etc.). In some specific implementations, each wireless input channel 150 corresponds to input channels 120A and 120B for receiving hardwired input connections (e.g., at connectors 130A and 130B). That is, the loudspeaker 10 enables the user to wirelessly connect or connect via hardwired connections to the same input channels (e.g., channel 1, channel 2, etc.). Figure 4 and Figure 5 The example shown illustrates two wireless transmitters 140A and 140B, which correspond to different wireless input channels 150A and 150B and enable different wireless connections between the source device and channels 150A and 150B.

[0073] Figure 5 Additional components in a loudspeaker circuitry system used to perform audio and / or control processes are shown, including, for example, an analog-to-digital converter (ADC) 152 and stereo digital-to-analog converters 154A, 154B, and 154C. Certain data and signal flow paths are shown for illustrative purposes and are not intended to limit various specific implementations. In some cases, wireless connection flow paths are compared to hardwired connection flow paths by using the term "wireless."

[0074] Figure 6 This is a close-up view of the docking station 160 for housing the transmitter 140, with the transmitter 140 removed. In various embodiments, the transmitter 140 is configured to mechanically engage and disengage from the loudspeaker 10 at the docking station 160. According to some embodiments, the depth of the docking station 160 is greater than its width or height, thereby allowing it to accommodate connectors for each transmitter 140. In certain cases, the transmitter 140 can be detached from or attached to the loudspeaker 10 at the docking station 160 without tools or other external equipment. For example, the transmitter 140 may be configured to connect to the docking station 160 via an interlocking arm or hook, a spring-loaded mounting, a force-fit connector, etc. In these cases, the user can manually connect and disconnect the transmitter 140 from the loudspeaker 10.

[0075] Figure 7This is a side view of a set of transmitters 140 removed from dock 160. Figure 8 Show Figure 7 End view of transmitter 140. (Reference) Figures 6 to 8 The transmitter 140 may be configured to slide in and out of the dock 160 on one or more rails 170 or other guiding members within the dock 160. In some cases, each dock 160 has a pair of rails 170 for aligning the corresponding transmitter 140 during docking. In some specific implementations, such as Figure 8 As shown, the launcher 140 may include recesses 180 complementary to the guide rail 170 (two are shown in this example). In other cases, the recesses may be positioned in the dock 160 and the guide rail (or similar protrusion) may be positioned on the launcher 140. That is, the launcher 140 in the dock 160 can be aligned using complementary alignment features of any kind. In an additional specific embodiment, the launcher 140 includes a material 190 at the interface that conforms to the dock 160. This conforming material 190 may differ from the more rigid material located on other parts of the launcher 140, and may achieve a desired, consistent fit between the body of the launcher 140 and the dock 160.

[0076] 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 Figure 7 As shown, transmitter 140 may include a power button 200 for powering on and / or powering off transmitter 140. In some embodiments, as optionally shown in dashed lines, transmitter 140 may also include a mute button 210 for muting the output from transmitter 140.

[0077] In certain specific implementations, such as Figure 7 As shown, one of the transmitters 140A includes a tip-sleeve (TS) audio connector 220 for coupling with a source device. As shown, the TS audio connector 220 is configured to nest or otherwise retract into the body of the transmitter 140A, which protects the connector 220 and enables docking and removal from the docking station 160. Figure 7The connector is shown in an intermediate state, with a portion of the TS audio connector 220 external to the body of the transmitter 140. It should be understood that in some embodiments, a tip-ring-sleeve (TRS) audio connector may be used instead of the TS audio connector 220. The TS audio connector 220 may be configured to couple to a source device such as an electrical instrument (e.g., a guitar, keyboard, etc.) or any other output device with a corresponding TS mating connection. In an additional embodiment, one of the transmitters 140B includes an XLR audio connector 230 for coupling to a source device. The XLR audio connector 230 may be configured to couple to a source device such as a microphone or other line-level source. In various embodiments, each docking station 160 is configured to receive any transmitter 140. That is, a first docking station 160A may be configured to receive either transmitter 140A or transmitter 140B, and a second docking station 160B may be configured to receive either transmitter 140A or transmitter 140B. Furthermore, it should be understood that the input connector 130 can be configured to physically connect with a TS audio connector, a TRS audio connector, and / or an XLR audio connector.

[0078] As described herein, docking station 160 enables physical and electrical connections with transmitter 140 for storage, power supply / charging, and communication. See, for example, [link to documentation]. Figure 7 and Figure 8 Each docking station 160 may include an electrical connector and / or a data connector 240 for coupling with a corresponding connector 240' (illustrated inside the body) on the transmitter 140. In some cases, the electrical connector and / or data connector 240 may include a USB connector. In a particular example, the connector 240 (e.g., a USB or variant such as a USB-C connector) enables software updates to the transmitter 140 or Debug Attachment Mode (DAM) operation at the transmitter 140.

[0079] Dock station 160 may also include a spring-loaded coupling element 250 and a magnet 260 (or multiple magnets). In some cases, the spring-loaded coupling element 250 allows the user to perform a push-engage function and / or a push-release function to couple and disconnect the transmitter 140 from dock station 160, respectively. In some cases, when docked via dock station, the outer surface of the transmitter 140 is substantially flush with the outer surface of the housing 22. This position may be maintained by the spring-loaded coupling element and the magnet 260. In some cases, the spring-loaded coupling element 250 enables the release of the transmitter 140, allowing the user to grasp the transmitter 140 to remove it from dock station 160. In certain cases, the connector 240 (e.g., a USB connector) is maintained in an intermediate position such that the transmitter 140 remains connected to the magnet 260 and connector 240 even after the spring-loaded coupling element 250 is released. In other words, the force required to overcome the coupling between the transmitter 140 and the connector 240 and the magnet 260 is greater than the spring force of the coupling element 250. In this sense, the connector (e.g., a USB connector) 240 has a minimum holding force to maintain a data connection with the amplifier 10.

[0080] In some cases, each wireless transmitter 140 has a battery and is configured to initiate charging of the battery in response to access to one of the docking stations 160. For example, in response to detecting a connection (e.g., a USB connection) at connector 240, the processor at the loudspeaker 10 is configured to initiate charging of transmitter 140.

[0081] In additional embodiments, each transmitter 140 is configured to connect a source device (e.g., an instrument, microphone, etc.) to a corresponding wireless input channel (e.g., channel 1, channel 2, etc.) in response to a detected connection to the source device. In some embodiments, once a user connects transmitter 140 to the source device, transmitter 140 automatically pairs the source device with the input channel (e.g., channel 1, channel 2, etc.). In some embodiments, if transmitter 140 was in a sleep or standby state before connecting to the source device, transmitter 140 is configured to wake up in response to a detected connection to the source device. In certain cases, transmitter 140 in a sleep or standby state wakes up first and then connects the source device to the input channel in response to a detected connection.

[0082] As described herein, when the loudspeaker 10 has multiple transmitters 140 for transmitting signals to multiple input channels (e.g., channel 1, channel 2), the processor at the loudspeaker 10 is configured to receive audio input from each wireless input channel. In certain cases, each wireless input channel has a separate wireless antenna. In some cases, a separate antenna is dedicated to the corresponding wireless input channel. Figure 9A perspective cross-sectional view of a portion of the loudspeaker 10 is shown, illustrating an example of two separate wireless antennas 300A and 300B (e.g., radio frequency (RF) antennas) along with a Bluetooth (BT) antenna 310. In some specific embodiments, each antenna 300A and 300B is positioned and oriented such that it has approximately uniform omnidirectional sensitivity along a plane to wireless signals from its corresponding wireless transmitter 140. That is, along a given plane, such as at a height relative to the ground or floor surface, antennas 300A and 300B are each approximately uniformly sensitive to wireless signals from their respective transmitter 140 in all directions. This allows a user to connect the wireless transmitter 140 for any channel to a source device (e.g., a microphone, instrument, etc.) and move around the loudspeaker 10 within a plane without significant differences in wireless signal quality. In some cases, as described herein, the loudspeaker 10 is configured to operate in multiple orientations, and each antenna 300A, 300B maintains approximately uniform omnidirectional sensitivity along the plane to wireless signals from the corresponding transmitter (e.g., transmitter 140A, transmitter 140B), regardless of the orientation of the loudspeaker 10.

[0083] In some specific implementations, the audio input to the loudspeaker 10 may be provided by one or more control elements 24, such as via a command interface, GUI, dial pad, buttons, etc. Figure 4 Control. In an additional specific implementation, 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 use commands from the application to control the selection of audio input (e.g., from a Bluetooth device, transmitter 140A, transmitter 140B, etc.). The application runs on a connected smart device such as a smartphone, tablet computer, or dedicated controller.

[0084] In an additional specific implementation, the loudspeaker 10 is configured to wirelessly connect to a first additional portable speaker via one of its wireless input channels. For example, the loudspeaker 10 may connect to the additional, similar loudspeaker via Bluetooth (e.g., via BT antenna 310) or via another wireless communication protocol (e.g., Wi-Fi). In some of these cases, the loudspeaker 10 may provide audio output to the first additional portable speaker via a wireless connection.

[0085] In yet another specific embodiment, the loudspeaker 10 is configured to wirelessly connect to a second additional portable speaker (e.g., similar to the loudspeaker 10) via a wireless input channel and a line output connector at the second additional portable speaker. In these cases, the loudspeaker 10 is configured to connect via one of the line output connectors 350 ( Figure 4The coupled wireless transmitter 140 receives audio input from a second additional portable speaker, thereby forming a wireless daisy chain between the individual loudspeakers 10.

[0086] As described herein, the loudspeaker 10 is configured for both wired power (hardwired) and portable (e.g., battery-powered) applications. That is, as Figure 4 As shown, housing 22 may include a hardwired power connector 360 for charging an onboard battery (retained within housing 22) that supplies power to transducers, processors, audio input modules, etc. The hardwired power connector 360 may also provide power for charging wireless transmitter 140, which, as described herein, includes an onboard power storage device (e.g., one or more batteries). In various specific embodiments, one or more batteries in loudspeaker 10 and / or transmitter 140 are rechargeable and / or replaceable batteries.

[0087] Automatic input channel detection In a particular implementation, 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 signal received from the hardwired input connector 130 and / or the wireless transmitter 140 based on one or more connection states or connection sequences. Figure 10 This illustrates methods executed by processor 100 in managing input connectors according to various specific implementations. For example, in some cases, processor 100 is configured to detect a hardwired audio input connector at connector 130 (process P1) and the status of a wireless connection with transmitter 140 (decision D1), and if the wireless connector precedes the hardwired connector at connector 130 (D1 is yes), processor 100 adjusts the audio signal from hardwired connector 130 (process P2). If the wireless connector does not precede the hardwired connector (D1 is no), processor 100 uses the audio input from hardwired connector 130 as the main audio output (process P3).

[0088] In certain implementations, decision D1 (detecting the state of a wireless connection with the transmitter) includes checking the presence of the wireless transmitter 140 in the corresponding docking station 160 before determining whether to detect audio input from the source device via the wireless connector 150. In some of these cases, the processor 100 may first determine whether the wireless transmitter 140 is powered on, and if so, then determine whether the transmitter 140 is paired with a corresponding channel (e.g., channel 1 or channel 2). In other cases, the processor 100 determines whether audio input is being received via the paired wireless transmitter 140. According to some implementations, if the wireless transmitter 140 is powered on and paired with a corresponding input channel (e.g., channel 1 or channel 2), the loudspeaker 10 modulates only the audio signal from the hardwire connector 130 (process P2). In other implementations, if the wireless transmitter 140 is paired and is receiving audio input from that transmitter 140, the loudspeaker 10 modulates only the audio signal from the hardwire connector 130 (process P2). If the processor 100 determines that the transmitter 140 is powered on but not paired or has no audio input, the processor 100 prioritizes the hard-wired connection and outputs the audio input from the connector 130 as the main audio (process P3).

[0089] In a particular example, adjusting the audio signal in process P2 includes switching the input channel 120 for hardwired connector 130 to the effects loop. In some of these cases, adjusting the audio signal in process P2 includes adjusting the pre-amplification order of the audio signal (from hardwired connector 130) before providing audio output, for example by prioritizing the amplification of the wireless signal from transmitter 140 over the signal from hardwired connector 130. In various specific implementations, audio input from a source device (e.g., a microphone, instrument, connected additional speaker, or audio gateway) received via hardwired connector 130 is received as a digital audio input and converted to an analog audio signal. In a particular case, transmitter 140 transmits at a frequency of approximately 2.4 GHz.

[0090] Return to Figure 4In a particular implementation, processor 100 is configured to select audio input based on commands from an application (e.g., between transmitters 140A, 140B, and connector 130), which runs on a connected smart device 400 (e.g., a smartphone, smartwatch, tablet, controller, etc.). In certain cases, smart device 400 runs or otherwise accesses a program (e.g., an application) configured to control functions of amplifier 10 (e.g., selecting input, adjusting volume and / or equalization settings, controlling power settings (e.g., on / off / standby)). In some cases, the functions of the application may be executed on a dedicated controller, in addition to or as an alternative to smart device 400.

[0091] like Figure 4 The diagram further shows that the loudspeaker 10 may include a hardwired power connector 360 (e.g., for connection to an external power source) for charging the onboard battery and powering the loudspeaker 10.

[0092] Dynamic display features Figure 11 A close-up view of the display 500 is shown, which may include... Figure 4 One or more control elements 24 are shown. The display 500 may be located on any surface of the loudspeaker 10, and in certain cases, near the control elements 24. Figure 11 Examples of control elements 24 shown include volume adjustment controls (e.g., knobs) 505 for each of a plurality of inputs (e.g., channel 1, channel 2, and BT inputs). In some specific embodiments, display 500 includes a plurality of sub-displays 510A, 510B, 510C. One or more aspects of display 500 may include digital display elements, such as digital screens or windows, for example, as shown in sub-displays 510A, 510B, 510C. In some cases, the sub-displays include organic light-emitting diodes (OLEDs).

[0093] In various specific implementations, such as Figure 11 and Figure 12 As shown, the orientation of the display 500 is configured to change in a first orientation in response to detecting a change in the orientation of the loudspeaker 10. Figure 11 ) and second orientation ( Figure 12 Adjustments are made between two or more orientations. That is, when adjusting the loudspeaker orientation between two or more orientations, the display 500 (e.g., including one or more sub-displays 510A, 510B, 510C) is adjusted between at least two orientations. Figure 11 The first orientation of the display 500 relative to the loudspeaker 10 is shown, and Figure 12A second orientation of the display 500 relative to the loudspeaker 10 is shown. In some specific embodiments, the orientation of the display 500 is designed to be easily discernible to a user given a loudspeaker orientation, for example, read from left to right and vertically oriented. As described herein, the loudspeaker 10 can be configured to operate in at least three different predetermined playback orientations (e.g., such as...). Figure 1A , Figure 1B and Figure 1C (As shown). In some examples, the first orientation of the display 500 is associated with two or more of the playback orientations (e.g., as shown). Figure 1A and Figure 1B Corresponding to the second orientation of the display 500 (as shown), the second orientation of the display 500 corresponds to different playback orientations (e.g., in...). Figure 1C (corresponding to) in the middle.

[0094] As described herein, the processor 100 and the orientation sensor 520 for indicating the orientation of the loudspeaker 10 ( Figure 5 Coupling. The orientation sensor 520 may include a gyroscope, magnetometer, accelerometer, and / or inertial measurement unit (IMU), and may be configured to provide data on changes in orientation to the processor 100 in response to the detection of such changes, for example, modified by a threshold and / or hysteresis factor. Figure 11 and Figure 12 In the specific example shown, display 500 includes a set of visual signal indicators 530 corresponding to input channels (e.g., hardwired channel connectors 130A, 130B and / or wireless connectors 150A, 150B). Figure 11 and 12 As shown, the visual signal indicator 530 can (e.g., via hardwired connectors 130A, 130B and / or wireless connectors 150A, 150B) provide visual feedback on the signal received at each input channel. In one example, as... Figure 13 A close-up view of the visual signal indicators 530 shows that each of the set of visual signal indicators 530 has a lower signal terminal 600 and a higher signal terminal 610, which span between: input channels (connectors) 130A, 130B or docking stations 160A, 160B and the corresponding display screens 510A, 510B associated with a given channel in the channel. According to some specific embodiments, each visual signal indicator 530 is configured to indicate one or more of the following: i) no signal (e.g., lack of fill, as shown in channel 2); ii) sufficient signal (e.g., green, as shown in channel 1); or iii) clipping (e.g., inconsistent signal or high signal level, such as sampling at approximately 50ms intervals and, for example, red in the BT channel). In some cases, for example, when the loudspeaker 10 is in an upright orientation ( Figure 12 , Figure 13 The visual signal indicator 530 crosses from the lower signal terminal 600 on the left side of the display 500 to the higher signal terminal 610 on the right side of the display 500.

[0095] In an additional specific implementation, the display 500 also includes a set of visual battery power indicators 620 ( Figure 11 , Figure 12 This set of visual battery level indicators corresponds to each detachably housed wireless transmitter 140, which is associated with each wireless input channel 150. In certain cases, the battery level indicator 620 can indicate the remaining battery level (e.g., in percentage, charge, and / or time) of a transmitter 140 not present in a corresponding docking station 160. Additionally, when a transmitter 140 is in a given docking station 160, the battery level indicator 620 can display indicators indicating that the battery is charging and / or fully charged (if applicable). The battery level indicator 620 can also indicate the battery level in a connected Bluetooth device, for example via… Figures 11 to 13 The Bluetooth device connected via the BT channel is shown.

[0096] In a specific implementation, processor 100 is also configured to operate in smart device 400 ( Figure 4 The application communicates with the smart device 400 to provide additional visual or audible signal indicators. For example, a visual signal indicator at smart device 400 may be displayed progressively via the application interface to provide the user with information about the signal received via the input channel. The visual signal level indicator at smart device 400 may be similar in format and / or style to the visual signal indicator 530 on the display of loudspeaker 10, or may take a different format and / or style. In various specific implementations, the visual signal level indicator at smart device 400 is part of a digital display. Additionally, the application may activate audible signal indicators, such as audible beeps, chimes, or tones, clipped sounds, etc., via the speaker of smart device 400 to indicate the characteristics of the signal received at the channel. Furthermore, the visual and / or audible signal indicators may include information about suggested adjustments to improve the signal received at speaker 10. For example, the suggested adjustments may include messages suggesting that the user adjust (e.g., at the hardwired connector 130) the physical connection or that the user move the transmitter 140 closer (e.g., to the speaker 10 for the wireless transmitter 140) (e.g., to make it visual and / or audible).

[0097] In an additional embodiment, processor 100 is configured to provide an error indicator at display 500 in response to detecting that speaker 10 is incorrectly oriented relative to a predetermined playback orientation. For example, processor 100 may provide an error indicator (e.g., a visual indicator at display 500, and / or an audible indicator via transducers 82, 84 indicating that speaker 10 is tilted or inverted). In some embodiments, the tilt position is indicated by speaker 10 being in a position between predetermined playback orientations, or otherwise in an unstable position. In an additional embodiment, the tilt position is indicated by speaker 10 being in a position relative to a predetermined playback orientation. Figure 1A , Figure 1B and Figure 1C The tilt position is defined by three pre-determined loudspeakers 10 with different orientations. The tilt orientation can be defined as any position where the upper surface of the loudspeaker 10 (e.g., at the top portion 51) is lower than the lower surface (e.g., at the bottom portion 52).

[0098] Return to Figure 11 and Figure 12 In some examples, display 500 may include three distinct sub-displays 510A, 510B, and 510C, each associated with an actuable button, knob, switch, etc. In some cases, the actuable button includes control 505. Although button 505 is shown as separate from the associated sub-display 510, in some implementations, sub-display 510 may be able to receive button commands other than or in lieu of button 505. That is, display 510 may include a touch interface (e.g., a capacitive touch interface) for receiving touch commands from a user. In any case, button 505 (and / or display 510) may be configured to receive one or more commands, and in certain cases, a long press command at a given button 505 presents a configuration menu on the associated display 510. The configuration menu may include configuration selections and / or adjustment options for various amplifier configurations, such as: battery mode (e.g., low power mode), settings (e.g., audio settings such as equalization settings, or sleep timer settings), and / or a shutdown menu that enables the amplifier 10 to be turned off. In certain specific implementations, such as Figure 4 As shown, the display 500 also includes a tone matching preset switch 630 for tone matching of each input channel, including the wireless channel input from the transmitter 140.

[0099] Audio monitor and network communication link In a specific implementation, as described herein, the loudspeaker 10 is configured to implement audio monitoring and / or network communication functions. For example, return Figure 5In some cases, processor 100 (connected to audio input module 110) is configured to, for example, receive audio input signals from one or more input channels, process the input signals, and provide audio output signals (to amplifiers) to transducers 82, 84, and to a network communication link (e.g., to USB, such as a USB-C connector / port), for example, via an amplifier. In certain embodiments, the USB link (e.g., to USB) includes a USB audio link. Because network communication is facilitated via a to USB connection in various embodiments, the network communication link can also be referred to as a USB audio link. In some cases, the input signal is connected via a plug-in mode channel 120 of a wireless channel 150 or a Bluetooth (BT) channel. Figure 12 The processor 100 is provided as described in various specific embodiments herein. In some cases, the processor 100 is configured to provide a first set of audio output signals to transducers 82, 84 and a second set of audio output signals to a USB audio link (or network communication link; to USB). As described herein, processing the audio input signals may include adjusting at least one of the relative signal level, equalization, or reverberation of one or more of the audio input signals.

[0100] In certain specific implementations, the first set of audio output signals acts as a monitor of the audio input signals, for example, as a local output at transducers 82 and 84 at the loudspeaker 10. In these cases, the second set of audio output signals 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 enables the user to provide audio output locally and synchronously with the monitor while streaming or recording audio output via the network communication link (USB audio link).

[0101] In a specific example, such as Figure 14As illustrated in system 700, the loudspeaker 10 is coupled to the 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, cellular network, or other communication network (including, for example, an internet connection). In a particular example, the network interface device 710 includes a computing device with a processor and memory and may be coupled to the loudspeaker via a hardwired or wireless connection (or link) 720 (illustrated by dashed lines). In some cases, the computing (network interface) device 710 includes a digital audio workstation (DAW) 730, which may include electronic devices or application software for recording, editing, and generating audio files. In some specific implementations, the DAW 730 includes an interface (e.g., a display and / or controls) for enabling a user 740 to control a second set of output signals. In some cases, the functionality of the DAW 730 can be integrated into the processor 100 in the loudspeaker 10, for example, as a software stack.

[0102] exist Figure 14 In the example depiction, user 740 is shown having an audio input device 750, such as a microphone, which may include a wired or wireless connection to amplifier 10. In certain cases, audio input device 750 is, for example, via channels 120, 150 (…). Figure 5 Audio input signals are provided to the loudspeaker 10. It should be understood that multiple audio devices may provide input to the loudspeaker 10 (e.g., two or more instruments, mixing devices, digital audio output devices, BT connection devices, etc.). As described in the various specific embodiments herein, wireless and / or hardwired inputs may be provided to the loudspeaker 10 and mixed and / or prioritized according to one or more rules.

[0103] Return to Figure 14 In the example, loudspeaker 10 (e.g., processor 100, Figure 5The loudspeaker 10 is configured to receive audio input signals from audio input device 750 and / or user's smart device 760, and process those input signals to provide audio output signals. In some cases, the loudspeaker 10 includes an amplifier configured to provide amplified audio signals from the audio input signals and / or audio output signals, for example, to transducers 82, 84. In a particular case, a first set of audio output signals is output by transducers 82, 84 at the loudspeaker. In this case, the first set of audio output signals acts as a monitor of the input signals (e.g., from audio input device 750). Furthermore, the processor 100 is configured to provide a second set of audio output signals to, for example, computing device 710 via link 720. In a particular case, the second set of audio output signals is transmitted via network communication link 720 to at least one of a DAW 730, a live streaming, or a network recording device. According to various specific embodiments, the first set of audio output signals and the second set of audio output signals (e.g., as outputs at transducers 82, 84) are provided and output to computing device 710 substantially simultaneously.

[0104] In some examples, the first set of audio output signals and the second set of audio output signals enable user 740 to provide output to both devices (amplifier 10 and computing device 710) at approximately the same time based on a common audio input. For example, user 740 may use amplifier 10 as an audio monitor (or local output device) and network link approximately simultaneously to provide a “live stream” of audio input (e.g., a performance).

[0105] Figure 15 It shows Figure 4 Examples of simplified views of control element 24, including interfaces, connectors, knobs, switches, etc. Figure 15 A set of adjustment controls (e.g., knobs) 505a, 505b, and 505c on the user interface 800 are also shown. The adjustment controls 505a, 505b, and 505c may correspond to three different input channels (channel 1, channel 2, and channel 3 (BT)) available for use with the loudspeaker 10. It should be understood that in some specific embodiments, a similar user interface 800, including one or more control elements in control element 24, may be copied (or mirrored) on a digital display (such as on computing device 710 or smart device 760). Figure 15In the example depiction, multiple adjustment controls 505 are configured to enable adjustment of channel audio (e.g., channel 1, channel 2, channel 3 (BT)) and / or access to additional functions of the loudspeaker 10. In some examples, adjustment controls 505 enable adjustment of the output volume of one or more channels (e.g., channel 1, channel 2, channel 3 (BT)). In a particular implementation, adjustment controls 505a, 505b, and 505c respectively adjust the output volume of channel 1, channel 2, and channel 3. In one example, adjustment control 505c enables selection of one or more operating modes, including a "live streaming" mode, whereby a second set of audio output signals is enabled and provided to another device (e.g., via USB, computing device 710). According to some implementations, actuating adjustment control 505c triggers one or more additional interface displays 810, 820, which may be provided at interface 800 and / or on a connected device (such as computing device 710 or another smart device running a control application for loudspeaker 10). In some cases, the additional interface displays 810, 820 provide instructions and / or mode selection for the multi-mode operation of the loudspeaker 10.

[0106] In one example, the loudspeaker 10 is configured to operate in a first mode that 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 embodiments, a second mode (e.g., live streaming) includes both outputting the first set of audio output signals (e.g., as a monitor output to transducers 82, 84) and the second set of audio output signals (e.g., to computing device 710 and / or additional network-connected devices). In some embodiments, switching between the first and second modes includes multimodal adjustment at interface 800. In some examples, multimodal adjustment includes long-press commands, turn-on commands, etc. Figure 15 Examples of long-press command instructions at interfaces 810 and 820 are shown to enable the selection of a second or subsequent operation mode (e.g., live streaming). Figure 16 and Figure 17 The example illustrates the process of selecting a second or subsequent operating mode (e.g., live streaming) via the rotation of adjustment control 505c through interfaces 810 and 820. In this example implementation, a single adjustment control (e.g., 505c) can be used to switch between operating modes at interface 800.

[0107] In some cases, within a given mode, for example, when both a first set of audio output signals and a second set of audio output signals are provided (also referred to herein as live streaming), processor 100 implements operation in at least two (sub)modes, including a first mode and a second mode, in which the volume levels of the first set of audio output signals (to the amplifier) ​​and the second set of audio output signals (to the USB) are coupled, and in the second mode, the volume levels of the first set of audio output signals (to the amplifier) ​​and the second set of audio output signals (to the USB) are decoupled. That is, in some specific implementations, processor 100 implements independent adjustment of the first set of audio output signals (to the amplifier) ​​and the second set of audio output signals (to the USB). For example, processor 100 can be configured to implement different volume controls for the first set of audio output signals (to the amplifier) ​​and the second set of audio output signals (to the USB). In some cases, different volume controls include applying different gains to the 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 command the audio input module 110 to apply different gains to the input signals (e.g., from the insert mode audio input via channel 120 and / or from the wireless input at channel 150) to achieve different volume control of the output signals (to the amplifier and to the USB). Figure 18 and Figure 19 The diagram illustrates example interface development for different volume controls in a live streaming mode, where processor 100 responds to actuation of adjustment control 505c (e.g., long press, release, repeated press and release, etc.) to display different interfaces 810, 820, thereby enabling independent control of the volume of the first audio output and the second audio output, respectively. For example, interface 820 displays a "monitor volume" control that allows independent control of the volume of the first audio output (to the amplifier) ​​relative to the volume of the second audio output (to USB). Figure 19 Additional (e.g., subsequent) actuation (e.g., rotation, sliding, etc.) of the adjustment control 505c is shown to adjust the volume of the first audio output (to the amplifier) ​​while maintaining the volume level of the second audio output (to the USB).

[0108] Furthermore, the processor 100 can implement different equalization (EQ) settings and / or different mixing settings for one or both of the first set of audio output signals (to the amplifier) ​​and the second set of audio output signals (to the USB). In some cases, different mixing settings are applied to the mixing of at least two inputs (e.g., inputs to channel 1, channel 2, and / or channel 3 (BT)). In some cases, adjusting the monitor volume (first audio output), EQ settings, and / or mixing settings is only available on the interface 800 at the amplifier 10. In other cases, the monitor volume, EQ settings, and / or mixing settings can be adjusted via an interface on a connected smart device (such as computing device 710).

[0109] In an additional specific implementation, the loudspeaker 10 also includes audio inputs (e.g., multiple channels 120, 150, and a wireless channel (BT)). Figure 5 A mixer coupled to the audio input module 110. In some cases, the mixer is a component in or coupled to the audio input module 110, such as electronic components and / or a software stack. In certain cases, the audio input to the amplifier 10 may include, for example, at least two or at most 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 aspects, the mixer is configured to provide a second set of audio output signals (to USB) as a dual-single-channel mix of multiple input channels (channel 1, channel 2). In additional specific embodiments that include the mixer, one or more adjustment controls 505 may enable adjustment of the mix. For example, during default operation (e.g., single-output mode, such as to the amplifier), adjustment control 505a may control the volume of channel 1, adjustment control 505b may control the volume of channel 2, and adjustment control 505c may control the volume of channel 3 (BT). When the amplifier 10 operates in dual-output mode (e.g., live streaming mode, or first audio output (to the amplifier) ​​and second audio output (to USB) respectively), the adjustment controls 505a, 505b, and 505c can enable the mixer's attenuation and / or the level of the corresponding channel within a dual-single channel mix. For example, when live streaming mode is activated, the adjustment controls 505a, 505b, and 505c can enable attenuation adjustment and / or channel level adjustment for the corresponding channel (e.g., channel 1, channel 2, channel 3 (BT)) in a dual-single channel mix.

[0110] In a particular implementation, after activating the live streaming mode, the loudspeaker 10 remains in that mode until a trigger is detected. The trigger may include a power cycle event, disconnection of one or more input devices, or a command received at an interface (e.g., interface 800 and / or on a connected device (such as computing device 710 or smart device 760)).
