A digital amplifier may refer to an amplifier that amplifies a signal in a digital state. A digital amplifier can convert an analog signal into a digital signal, amplify it, and convert the amplified digital signal into an original analog signal. Digital amplifiers have the advantage of preventing signal distortion compared to analog amplification circuits because signal transmission and amplification are performed in a digital state, and noise can be reduced compared to analog amplifiers to have a high signal/noise ratio. Digital signal amplification technology using digital amplifiers is used in various fields such as image processing, audio processing, switching power supplies, and A/D conversion devices. For the above-described digital signal amplification, the digital amplifier may be equipped with a power supply device and may receive power from the power supply device. Here, in systems such as broadcasting systems composed of high-capacity digital amplifiers, even when digital amplifiers are not used, if power is continuously supplied from the power supply, unnecessary energy consumption may occur, and heat generation from the power supply may cause damage to the equipment. Malfunction may occur. In consideration of the above, the following describes a method of increasing energy efficiency by minimizing power consumption when a digital amplifier is not used.

The following describes a method of performing power saving operations by controlling the power supply and digital amplifier in a smart sound system consisting of integrated monitoring software running on a user device such as a PC or smartphone, POE, a digital amplifier device module connected to the POE, and a speaker. Describe about. As an example, the description below is based on a smart sound system, but it may not be limited to this and can be equally applied to other systems to which digital amplifiers are applied. However, for convenience of explanation, the following content is described based on the smart sound system.

Figure 3 is a diagram showing a smart sound system applied to the present disclosure. Referring to FIG. 3, the smart sound system may include a user device 310 running integrated monitoring software, a POE 320, a speaker 330, and a digital amplifier device module 340. Here, the user device 310 running the integrated monitoring software may be a PC, smartphone, or other device. As an example, the user device 310 running integrated monitoring software may provide the user with monitoring information about signals output to the speaker 330 through the POE 320 based on the digital amplifier device module 340. there is. As an example, the user device 310 running integrated monitoring software may detect user input based on the integrated monitoring software. The control signal by user input is transmitted to the digital amplifier device module 340 to control the power supply (or power supply) and digital amplifier to adjust the signal output to the speaker 330. That is, the user can control the smart sound system through the integrated monitoring software 310, but may not be limited to this.

POE 320 can transmit power and data to speaker 330. Additionally, the POE 320 may cause the speaker 330 to output an audio signal based on a control signal transmitted from the user device 310 running integrated monitoring software and the digital amplifier device module 340. That is, the user can control the smart sound system to broadcast or output other audio signals through the speaker 330, and is not limited to a specific form. The digital amplifier device module 340 is connected to the POE 320 and can control the power supply and amplifier to amplify the digital signal. As an example, the digital amplifier device module 340 may include a main controller 341, a speaker selection unit 342, a line checker 343, an Amp 344, and a power supply 345. The main controller 341 is a controller that controls the digital amplifier device module 340 and can control the speaker selection unit 342, line checker 343, Amp 344, and power supply 345, Signals can be transmitted through the network. The main controller 341 may control the digital amplifier device module 340 based on a control signal transmitted from the network to output audio through the speaker 330. The speaker selection unit 342 may be a unit that determines which of the speakers 330 connected through the POE 320 to output audio. For example, there may be speakers corresponding to each power source in the power supply 345, and the speaker selection unit 342 may select the corresponding speaker. The line checker 343 may be configured to check the condition of the line connected to the POE 320 and the speaker 330, and measures the impedance of the line connected to the digital amplifier device module 340 to check whether there is a line abnormality. It may be a configuration to check. Amp 344 may be configured to amplify a signal using the above-described amplifier. As an example, the Amp 344 can amplify a digital signal corresponding to the audio signal output through the speaker 330, and the degree of signal amplification can be controlled by the main controller 341. As a specific example, the user can adjust the sound level or audio level based on the integrated monitoring software 310, and the user input for this is sent to the main controller 341 of the digital amplifier device module 340 through the POE 320. It can be transmitted and controlled. Here, power supply may be required for the Amp 344 to amplify the signal. The power supply 345 may be a device that is connected to the Amp 344 and supplies the power needed when the Amp 344 amplifies a signal. However, as described above, if the power supply 345 continuously supplies power to the Amp 344, energy consumption may be high and device failure may occur due to heat generation. Considering the above, it may be necessary to control the Amp 344 and the power supply 345 to reduce power consumption and operate the smart sound system efficiently.

4A and 4B are diagrams showing a power supply applied to the present disclosure. Referring to FIG. 4A , the power supply 345 may include an Amp power source 410, a public address equipment power source 420, and an AC power source 430. Additionally, the power supply 345 may further include other power sources and may not be limited to a specific embodiment. Here, the Amp power supply 410 may be configured to supply power to the Amp 344. For example, when the Amp power supply 410 is turned on, power may be supplied to the Amp 344, and when it is turned off, power may not be supplied to the Amp 344. Additionally, in Figure 4a, the Amp power source 410 may be 48V, 2KW, but this is only an example and may not be limited thereto.

The public address equipment power source 420 may be configured to supply power to the public address equipment. For example, public address equipment may be equipment for long-distance broadcasting between buildings, and may be equipment that performs broadcasting in consideration of emergency situations such as fire. Here, the public address equipment power source 420 may be controlled by the digital amplifier 340. As an example, the public address equipment power source 420 may be 24V, 700W, but this is only an example and is not limited thereto. The AC power source 430 may be configured to supply AC power to the equipment 347 . As an example, the AC power source 430 may be 220V, but this is only an example and is not limited thereto. Equipment 347 may include AC Amp and other broadcast equipment. Additionally, the power supply 345 may further include LAN communication 440, and power consumption may be checked in real time through LAN communication 440. Additionally, all power on/off operations can be performed through LAN communication 440. Specifically, it can be connected to the main controller 341 of the digital amplifier device module 340 based on LAN communication 440, and each power source can be controlled. Additionally, the power supply 345 can check the power consumption measured in the network in real time through LAN communication 440, and control the power supply 345 based on this. Based on the above, the user controls the power supply 345 linked to the main controller 341 of the digital amplifier device module 340 through the user device 310 running integrated monitoring software to turn on each power. /off operation can be controlled. Additionally, the power supply 345 can control the on/off operation of the above-described power sources based on power consumption checked in real time through the network. For example, if the power consumption measured in real time in the network is large, a specific power source may be turned off, but this is only an example and may not be limited thereto.

Additionally, as an example, referring to FIG. 4B, the power supply 345 may further include a sound source detecting power supply 450. Here, the sound source detecting power supply 450 is a power source for sound source detection and may consume less power than the Amp power supply 410. As an example, the sound source detecting power supply 450 may be 5V, 20W, but is not limited to this embodiment. Here, when the sound source detecting power supply 450 is turned on, the Amp power supply 410 may be turned off, and the power supplied to the Amp 410 can be reduced through the above-described process. When sound source detection 401 is performed based on the sound source detecting power supply 401, the Amp power supply 410 may be activated. In other words, sound source detection (405) is performed by maintaining only the sound source detection power (450) that is smaller than the Amp power supply (410), and when the sound source is detected, the Amp power supply (450) is activated to supply power to the Amp (344). This can amplify the signal.

Here, as an example, a state in which the sound source detecting power supply 450 is turned on and the Amp power supply 410 is turned off may be a power saving state. On the other hand, the state in which the Amp power source 410 is turned on based on the sound source detection 401 may be an activated state. More specifically, the power supply 345 does not need to continuously supply power in a state where there is no audio signal to be output. If power is continuously supplied by the power supply 345, energy consumption may be large and equipment failure may occur due to heat generation. In consideration of the above, the power supply 345 turns off the Amp power source 410, turns on only the sound source detecting power source 450 with a small amount of power, consumes less power, and then turns on the sound source detecting power source 401 based on the sound source detection 401. Power can be supplied by turning on the Amp power supply 410, and a specific method for this is described below.

Figure 5 is a diagram showing the state of the power supply based on sound source detection applied to the present disclosure. Referring to FIG. 5(a), the power supply 345 of the digital amplifier 340 may maintain a power saving state in which it does not continuously supply power to the Amp 344. For example, in a power saving state, the Amp power supply 410 may be turned off and power may not be supplied to the Amp 344. For example, in FIG. 5(a), since there is no sound source detection 401, the power supply 345 may maintain a power saving state and not supply power to the Amp 344. On the other hand, when the sound source is detected in FIG. 5(b), the power supply 345 turns on the Amp power supply 410 and switches to an active state to supply power to the Amp 344 through the Amp power supply 410. You can. That is, based on the sound source detection 401, power consumption can be reduced by switching to the activated state and supplying power only when power is needed to be supplied to the Amp 344.

Here, as an example, a smart sound system may include a sensor that detects a sound source. The sensor that detects the sound source may be configured to sense an audio signal, and when it senses a signal above the threshold, it can be determined that sound source detection 401 has been performed. As an example, the sensor may be installed in various locations based on a smart sound system, and is not limited to a specific embodiment. Additionally, as an example, the sensor may be installed in a PC, smartphone, or other device, and a sound source detection signal may be transmitted to the digital amplifier device module 340 based on the audio signal sensed by the device. That is, sound source detection 401 can be performed in various forms and is not limited to a specific embodiment.

Figure 6 is a diagram showing the state of a power supply applied to the present disclosure. Referring to FIG. 6(a), the power supply 345 may be switched to the activated state by sound source detection 401. As an example, sound source detection 401 may be event detection. More specifically, sound source detection 401 may be a type of event for switching the power supply 345 to an activated state, and is not limited to a specific form. As an example, the event may mean the above-described sound source detection, a user's touch input, or other actions to activate the power supply 345. For example, an event may be voice recognition, text recognition, motion recognition, or other recognition, and may not be limited to a specific type.

For example, the power supply 345 may be switched to an activated state by a voice recognition signal transmitted from an external terminal. The external terminal may be the user device 310 described above. That is, when the user device 310 recognizes the user's voice command and the recognized voice satisfies a specific command value, a voice recognition signal is transmitted from the user device to the digital amplifier device module, and the power of the digital amplifier device module that receives the signal is transmitted. Supply 345 can be switched to an active state to supply power to Amp 344. For example, the voice command may be a voice called 'Wakeup', and the specific command value may be voice information called 'Wakeup' by the user's own voice entered into the device through integrated monitoring software, and the user device It recognizes voice commands such as the user's wake-up, and when the recognized voice command matches the previously entered voice information, it generates a voice recognition signal and transmits it to the digital amplifier device module through a wired or wireless communication network. Accordingly, the digital The power supply of the amplifier device module can be switched to an active state. At this time, the algorithm for voice command recognition can be included in the integrated monitoring software, and the digital amplifier device module is also installed with software linked to the integrated monitoring software that can receive the voice recognition signal generated by the user device and perform the necessary actions. It may be.

Or, for example, the power supply 345 may be switched to an activated state by a character recognition signal transmitted from an external terminal. The external terminal may be the user device 310 described above. That is, when the user device 310 recognizes the user's character input and the recognized character (i.e., text) satisfies a specific command value, a character recognition signal is transmitted from the user device to the digital amplifier device module, and the digital amplifier device that receives it The power supply 345 of the amplifier device module can be switched to an active state to supply power to the Amp 344. For example, the character input may be a string called 'Wakeup', and the specific command value may be string information called 'Wakeup' that the user entered into the device through integrated monitoring software. Accordingly, the user device wakes up the user and When the same character input is recognized and the recognized character matches the previously entered string information, a character recognition signal can be generated and transmitted to the digital amplifier device module through a wired or wireless communication network, and accordingly, the power supply of the digital amplifier device module can be switched to the activated state. At this time, the algorithm for character input recognition can be included in the integrated monitoring software, and the digital amplifier device module is also installed with software linked to the integrated monitoring software that can receive the character recognition signal generated by the user device and perform the necessary actions. It may be.

For example, the power supply 345 may be switched to an activated state by a motion recognition signal transmitted from an external terminal. The external terminal may be the user device 310 described above. That is, when the user device 310 recognizes the user's motion command and the recognized motion satisfies a specific command value, a motion recognition signal is transmitted from the user device to the digital amplifier device module, and the power of the digital amplifier device module that receives the signal is transmitted. Supply 345 can be switched to an active state to supply power to Amp 344. For example, the motion command may be a motion called 'continuous touch input' for the user device, and the specific command value may be a motion called 'continuous touch input' based on the user's own motion entered through the integrated monitoring software on the device. It may be information, and the user device recognizes a motion command such as a continuous touch input applied in a specific direction of the user, and if the recognized motion command matches the entered motion information, it generates a motion recognition signal and transmits it to the digital amplifier device. The module can be delivered via a wired or wireless communication network, whereby the power supply of the digital amplifier device module can be switched to an active state. At this time, the algorithm for motion command recognition can be included in the integrated monitoring software, and the digital amplifier device module is also installed with software linked to the integrated monitoring software that can receive the motion recognition signal generated by the user device and perform the necessary actions. It may be.

Meanwhile, the user device may be in a standby state to enable one or more of the above-described voice recognition, text recognition, and motion recognition, and the detecting power may also be in a standby state (i.e., turned on).

Hereinafter, for convenience of explanation, the description will focus on an embodiment in which the event is sound source detection. In other words, the event can be represented by a sound source event, the event detection unit can be referred to as a sound source event detection unit that determines whether a sound source event exists, and the detecting power source can be referred to as a sound source detecting power supply that is a power source for sound source detection. .

Referring to FIG. 6(a), the power supply 345 maintains a power-saving state before detecting an event, and when it detects an event, it switches to an active state, turns on the Amp power supply 410, and supplies power to the Amp 344. can be supplied. Here, the power supply 345 may remain activated for a certain period of time from the time an event is detected. As a more specific example, when an event is detected, the power supply 345 is switched to the activated state and a deactivation timer may operate. Here, if no additional events are detected or audio signals are not output through the speaker before the inactivity timer expires, the power supply 345 may be switched back to the power saving state. For example, referring to FIG. 6(b), when an event is detected and the power supply 345 is activated and the deactivation timer is operating, if an additional event is detected, the deactivation timer is reset and the timer starts at the time the event is detected. can start again. As another example, if an event is detected and the power supply 345 is activated and power is supplied to the Amp 344 and an audio signal is output through the speaker 330, the deactivation timer may be stopped. For example, if the power supply 345 detects an event and continuously maintains the activated state, power consumption may be high, and the power supply 345 may be automatically switched to a power saving state after a certain period of time without use of the Amp 344. There is a need. As a specific example, a case may be considered where the power supply 345 switches to an activated state after detecting a sound source as an event and supplies power to the Amp 344, but the sound source detection malfunctions. Here, if no additional events are detected and the Amp 344 is not used, the power supply 345 may return to the power saving state after the timer expires for a certain period of time to reduce power consumption.

As another example, the deactivation timer may operate again when audio output to the speaker 330 is stopped and the Amp 344 is not used. Here, if the speaker 330 is output or the Amp 344 is not used, the deactivation timer may be reset and started. For example, when the deactivation timer expires after the use of the Amp 344 is terminated, the power supply 345 can be switched back to the power saving state, and power consumption can be reduced based on the above.

Figure 7 is a diagram showing the state of a power supply applied to the present disclosure. Referring to FIG. 7, when an event is detected, the power supply 345 may be activated and switched to an activated state in which power is supplied to the Amp 344. Here, after the power supply 345 is switched to the activated state, if an audio signal is not output to the speaker 330 or an event is not detected, the power supply 345 may be switched to the standby state. For example, even if an audio signal is not output to the speaker 330 or the Amp 344 is not used, the power supply 345 may not be immediately switched to the sleep state, but may be switched to the standby state in consideration of additional operations. For example, in the standby state, the Amp power source 410 is turned on (344), and the Amp (344) may be receiving power from the power supply (345). That is, although a signal is input to the Amp 344 and an audio signal is not output to the speaker 330 through the POE 320, power may be supplied to the Amp 344. Here, as an example, a user's touch input or additional input may be required in order for the power supply 345 to enter the power saving state. In other words, after the Amp power source 410 is turned on and activated in the power supply 345, it does not immediately switch to the sleep state even if the Amp 344 is not used, but switches to the sleep state only when there is a user touch input or additional input. It can be.

As another example, an off state may exist in which both the sound source detecting power supply 450 and the Amp power supply 410 described above in FIG. 4B are turned off. Here, since the sound source detecting power source 450 is also turned off, sound source detecting may not be performed, and the Amp power source 410 may be turned on only by a user input signal transmitted through the network. That is, the user can use the sound source detecting function by setting it to a power saving state in which the sound source detecting function is activated, or set the sound source detecting function to an off state where the sound source detecting function is not used, and is not limited to a specific embodiment.

8 and 9 are diagrams showing a method of activating a power supply applied to the present disclosure.

Referring to FIG. 8(a), based on sound source detection (or event detection), the Amp power of the power supply 345 may be turned on and power may be supplied to the Amp 344, as described above. Here, sound source detection may mean detection of a signal above a threshold value. For example, even for noise or other small-sized sound sources, power consumption may increase when the Amp power supply is turned on. Therefore, the Amp power supply 410 is not turned on for noise or other small-sized sound sources, and the Amp power supply 410 is turned on only when a signal above the threshold is detected so that power is supplied to the Amp 344. This can prevent malfunctions.

As another example, referring to FIG. 8(b), after detecting a sound source as a signal above the threshold, the Amp power supply 410 may be turned on through an additional input to supply power to the Amp 344. As a specific example, error handling for sound source detection may be necessary, and if power is supplied in response to a sound source rather than detecting a sound source that is actually intended to supply power to the Amp 344, unnecessary power consumption may occur. In consideration of the above, even if a signal above the threshold is detected, additional inputs can also be detected so that the power supply 345 is activated and supplies power to the Amp 344. As a more specific example, referring to FIG. 9, after a signal above the threshold is detected, when additional user input is detected based on a PC or smartphone, the Amp power supply 410 is turned on in the power supply 345. Power can be supplied by Amp (344).

As another example, if additional input is not detected within a certain period of time after detecting a signal above the threshold, the power supply 345 may be switched to an activated state to supply power to the Amp 344. More specifically, when the digital amplifier device module 340 detects a signal above the threshold, it does not immediately activate the power supply 345, but waits for a certain period of time and provides an indication to the user regarding the detection of a signal above the threshold. there is. As an example, information that a signal exceeding a threshold value has been detected may be provided to the user device 310 running monitoring software based on the digital amplifier device module 340. Here, if the detection of a signal above the threshold is due to an unintended error, the user may not switch the power supply 345 to the activated state. In other words, the user can cancel the activation state transition if a signal above the threshold is detected but the signal is an error.

On the other hand, if there is no user input for a certain period of time after a signal above the threshold is detected or a user input that activates the power supply 345 is detected, the power supply 345 is activated to supply power to the Amp 344. In other words, if a signal above the intended threshold is detected, the user can wait until the power supply is activated without taking any action. Alternatively, by active action of the user, the user may immediately supply power to the Amp 344 by providing user input that switches the power supply 345 to the active state with an indication of detection of a signal above the threshold, as described above. It is not limited to examples.

Figure 10 is a diagram showing a method of controlling a threshold applied to the present disclosure. As described above, in order to detect sound sources, there is a need to detect signals above a threshold value. As an example, referring to Figure 10(a), the threshold may be set to a preset value, and when a signal above the threshold is detected, it is determined that sound source detection (or event detection) has been performed, and the power supply is turned on as described above. The supply 345 can be switched to the activated state to supply power to the Amp 344.

As another example, referring to FIG. 10(b), multiple threshold values may be set. As an example, a first threshold and a second threshold smaller than the first threshold may be set. Here, sound source detection may be clear for signals above the first threshold, and upon detecting signals above the first threshold, the power supply 345 may be switched to the activated state. For example, detecting a signal above the first threshold may be a first type event, but may not be limited to that name. On the other hand, detecting a signal that is smaller than the first threshold and larger than the second threshold may be a second type event. Here, the second type event may be actual sound source detection intended by the user, but may be an unintentional detection error. In consideration of the above, the power supply 345 may be activated through additional user input for signals that are smaller than the first threshold and larger than the second threshold. That is, when detecting a signal above the first threshold, the power supply 345 is immediately switched to the activated state, and when detecting a signal smaller than the first threshold and larger than the second threshold, the power supply 345 is activated by the user. After indicator information inquiring about activation is provided, the user input for activation must be additionally detected to switch to the activation state. As an example, indicator information may be provided through a PC, smartphone, or other user device, and is not limited to a specific embodiment. That is, the user may not switch the power supply 345 to the activated state if sound source detection is an error, but may switch the power supply 345 to the activated state if sound source detection is intended.

Figure 11 is a diagram showing a method of performing sound source detection based on artificial intelligence (AI) applied to the present disclosure. For example, in order to reduce power consumption, the power supply 345 of the digital amplifier device module 340 may be deactivated, and when an event is detected through sound source detection, the power supply 345 may be activated to supply power, which is as described above. It's like a bar. However, there is a need to control errors related to sound source detection described above. For example, if sound source detection is intended by the user, but the detected signals are signals less than a threshold value, the power supply 345 may not be switched to the activated state. As another example, although a signal above the threshold value is detected, the signal may be caused by noise or noise introduced from the outside. As another example, activation of the power supply 345 may be intended for a specific signal although it is a signal above the threshold, and activation of the power supply 345 may not be intended for another specific signal, and differentiation of the corresponding signals may be necessary. there is.

Considering the above, errors can be reduced by constructing an AI learning model 1110 for sound source detection and detecting sound sources based on this. Here, as an example, the AI learning model 1110 may be learned based on sound source intensity, sound source frequency, sound source play speed, and other sound source-related information. Additionally, it can be learned based on sound source-related information or sound source detection-related information provided by the user. Afterwards, when the sound source is detected, the corresponding signal is provided as an input to the AI learning model 1110, and whether the power supply 345 is activated can be derived as an output value. Here, as an example, information on whether the power supply 345 is activated may be provided to the user, and feedback information may be provided from the user. That is, information about whether the power supply 345 is activated by the AI learning model 1110 and whether the output is provided correctly or incorrectly may be provided as feedback information. As an example, the AI learning model 1110 can be updated based on the above-described feedback information, thereby improving sound source detection accuracy.

As another example, as described above, power consumption can be checked in real time and power on/off can be controlled through LAN communication 440 of the power supply 345. Here, as an example, each power source in the power supply 345 may be turned on/off according to the total power consumption. As a specific example, when the total power consumption is below a preset level, sufficient power may be supplied if the power supply 345 is not overloaded, and each power source within the power supply 345 may operate. On the other hand, when the total power consumption is higher than a preset level, the power sources in the power supply 345 may operate based on priority. For example, the public address equipment power source 420 related to an emergency situation may have the highest priority, and the priority may be determined considering the power used. That is, the power operation of the power supply 345 may be controlled in consideration of the power consumption used in the network, but may not be limited to the corresponding embodiment.

Figure 12 is a diagram showing an operation method in an emergency mode applied to the present disclosure. Referring to FIG. 12, the digital amplifier 340 may operate in normal mode or emergency mode. For example, when operating in normal mode, power can be controlled by detecting a sound source as described above, or power can be controlled by considering network power consumption.

Here, the mode may be switched to emergency mode based on emergency mode detection 1210. As an example, the emergency mode detection 1210 can be switched by a user input that switches to the emergency mode on a user device such as a PC or smartphone. As another example, emergency mode detection 1210 may be switched by a sensor. For example, an emergency situation may be recognized based on a fire detection sensor or other sensors. As another example, emergency mode detection 1210 may be recognized through an emergency situation message sent from an external server. An emergency situation message may be a message transmitted through a server or platform managed by an emergency situation control agency or another external organization, and upon receiving the message, the emergency situation may be recognized.

Referring to FIG. 12, based on the emergency mode detection 1210, other power sources in the power supply 345 may be turned off and only the public address equipment power source 420 may be turned on. For example, even if there is sufficient power in the power supply 345, propagating an emergency situation may be the top priority in the emergency mode, and the remaining power sources may be turned off for safety considerations. Through this, malfunctions can be prevented in emergency mode. Here, as an example, the public address equipment power source 420 may be controlled by the main controller 341. Additionally, as an example, exiting the emergency mode can be performed by detecting a user input for exiting the emergency mode using a PC or smartphone. That is, the emergency mode can be automatically performed based on the above-described emergency mode detection 1210, but ending the emergency mode can be performed only by user input for safety considerations. However, this is only one example and may not be limited thereto.

Figure 13 is a flowchart showing an amplifier module applied to the present disclosure. Referring to FIG. 13, the amplifier module may be the digital amplifier device module 340 described above. Here, the amplifier module includes a control unit 1310, a signal input unit 1320, a power supply unit 1330, a sound source event detection unit 1340, an AI learning unit 1350, a network event detection unit 1360, and an external event detection unit ( 1370), an emergency mode detection unit 1380, and a signal output unit 1390.

Here, as an example, the signal input unit 1320 may detect an input signal, and the sound source event detection unit 1340 may determine whether there is a sound source event based on the detected input signal. If the detected input signal is determined to be a sound source event based on the sound source event detection unit, the power supply unit 1330 may supply power to the amplifier. As an example, the power supply unit 1330 may correspond to the power supply 345 described above, but may not be limited thereto. Afterwards, the signal output unit 1390 can output a signal based on the amplifier.

Here, as an example, the power supply unit 1330 may include an amplifier power source and a sound source detecting power source. Before the sound source event detection unit 1340 detects the sound source event, the sound source detecting power may be maintained in the turned-on state. On the other hand, the amplifier power may be maintained in a turned-off state, as described above. Thereafter, when a sound source event is detected based on the sound source event detection unit 1340, the amplifier power is switched to the turn-on state and power can be supplied to the amplifier. As another example, after a sound source event is detected based on the sound source event detection unit 1340, the amplifier power can be switched to the turn-on state only when additional input is detected through the external event detection unit 1370, which is Same as described above.

Additionally, a threshold for sound source event detection may be set. For example, if the signal strength of the detected input signal is greater than the threshold, a sound source event may be detected and power may be supplied to the amplifier.

As another example, a first threshold for detecting a sound source event and a second threshold smaller than the first threshold may be set. Here, if the signal strength of the detected input signal is greater than the first threshold, a sound source event may be detected and power may be supplied to the amplifier. On the other hand, when the signal strength of the detected input signal is less than the first threshold and greater than the second threshold, when additional input is detected based on the external event detection unit 1370, a sound source event is detected and power is supplied to the amplifier. can be supplied.

As another example, when an input signal is detected, the detected input signal is provided as an input to the AI learning model in the AI learning model unit 1350, and whether a sound source event is detected may be provided as an output of the AI learning model. . For example, the AI learning model is a model learned based on sound source intensity, sound source frequency, sound source play speed, and other sound source-related information, and the output is fed back to the AI learning model so that the AI learning model can be continuously updated.

Additionally, when a sound source event is detected based on the sound source event detection unit 1340, a deactivation timer may operate. Here, if there is no detection of an additional sound source event and no output signal generation through the amplifier until the deactivation timer expires, the amplifier power may be switched to a turn-off state.

In addition, if there is no additional sound source event detection or output signal generation through the amplifier before the expiration of the deactivation timer, an indication of output signal generation is provided to the user and an additional input is detected to turn off the amplifier power based on the indication. This allows the amplifier power to be turned off.

In addition, when both the sound source detecting power and the amplifier power of the power supply unit 1330 are turned off, the sound source event is not detected through the sound source event detection unit 1340, and the amplifier power is turned on only by the additional input that turns on the amplifier power. This switches to the turn-on state, allowing power to be supplied to the amplifier.

As another example, the power supply unit 1330 may further include public address equipment power and AC power. Here, at least one power source included in the power supply unit 1330 can be controlled by monitoring network power consumption in real time based on the network event detection unit 1360, as described above.

As another example, when an emergency mode is detected based on the emergency mode detection unit 1380, the power of the public address equipment may be turned on and the remaining powers of the power supply unit may be turned off, as described above.
