[0002] A sound adjustment controller is usually used to adjust the volume and pitch. The adjustment signal is transmitted to the micro control unit through the control module to control the sound generating unit to adjust the sound volume. It is used in electrical appliances such as floor washers and vacuum cleaners. After the user adjusts the working mode, the noise level of the electrical appliance changes, and then the voice broadcast sound volume is adjusted by the sound adjustment controller.

[0003] The invention with the publication number CN107181998A discloses an audio volume control system and method. A sound detection module is used to collect ambient sound signals and filter out the audio signals of the player from the ambient sound to obtain external sound signals. A control module is used to monitor the level of the external sound signals and adjust the audio volume according to the level.

[0004] However, the above-mentioned volume control system still has the following problems in the actual working process: Although the external noise can be detected in real time through the sound detection module to change the volume of the sound generating unit, when the real-time working sound detection module faces sudden and short-term external noise, it will also autonomously adjust the volume of the sound generating unit. This leads to the continuous adjustment of the sound volume by the sound generating unit during continuous operation, which affects the use and is not conducive to the voice broadcast work.

[0005] Therefore, we propose a controller for intelligently adjusting the sound volume to solve the problems mentioned above. Content of the Utility Model

[0006] The purpose of the utility model is to provide a controller for intelligently adjusting the sound volume, aiming to solve the problem that although the external noise is detected in real time through the sound detection module to change the volume of the sound generating unit, when the real-time working sound detection module faces sudden and short-term external noise, it will also autonomously adjust the volume of the sound generating unit. This leads to the continuous adjustment of the sound volume by the sound generating unit during continuous operation, which affects the use and is not conducive to the voice broadcast work.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A controller for intelligently adjusting the sound volume, including a main control panel. The main control panel includes a power module for overall power supply to ensure the working stability. The main control panel is connected with a key module and a speaker unit.

[0008] Preferably, the main control panel is connected to the button module through GND, and the button module is installed on the controller for the user to perform manual adjustment operations.

[0009] Preferably, the main control panel is connected to the button module through GND, so that the circuit formed by GND and the GPIO port changes the level state of the GPIO port, thereby triggering the corresponding control logic.

[0010] Preferably, the main control panel controls the volume of the speaker unit by sending an increase signal and a decrease signal.

[0011] Preferably, the main control panel includes an MCU unit, and the MCU unit is connected to the positive and negative poles of the power supply module to ensure that the power supply of the power supply module can provide stable power supply for the MCU unit.

[0012] Preferably, the main control panel includes a voice module, and the voice module is connected to the positive and negative poles of the power supply module to ensure that the voice module can obtain the required power supply voltage from the power supply module and thus work properly.

[0013] Preferably, the positive pole of the power supply module connects the MCU unit and the voice module in parallel.

[0014] Preferably, through the MCU unit, normal signal processing and control functions are ensured, and signals can be correctly received and sent to the voice module, thereby realizing the control of the voice module.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: For this intelligent controller for adjusting the sound volume, by the user operating the button module of the electrical equipment to adjust the gear required during the operation of the electrical equipment, and at the same time, the button module transmits the received gear information of the button to the MCU module of the main control panel, which after receiving and analyzing, controls the voice module and the speaker unit to emit sounds of different volumes, and intelligently presets the sound volume of the voice prompt according to the different noise levels of the electrical equipment in different modes, so that the user can hear clear and non-ear-piercing voice feedback. The specific content is as follows:

[0016] 1. The button module of the electrical equipment adjusts the gear required during the operation of the electrical equipment, and at the same time, the gear information of the button is transmitted to the MCU module of the main control panel, which after receiving and analyzing, controls the voice module and the speaker unit to emit sounds of different volumes, and intelligently adjusts the volume of the voice feedback according to the noise emitted by the electrical equipment.

[0017] 2. Electrical equipment in the low gear has less noise. Therefore, after analysis by the MCU unit, it controls the volume of the voice module and the speaker unit to provide feedback to the user at a relatively low volume, so that the user can clearly and not harshly hear the voice broadcast.

[0018] Electrical equipment in the high gear has greater noise. Therefore, after analysis by the MCU unit, it controls the volume of the voice module and the speaker unit to provide feedback to the user at a relatively high volume, in case the noise of the electrical equipment masks the voice broadcast.

[0019] Electrical equipment in the standby state has the least noise.

[0023] Please refer to Figure 1 , the present utility model provides the following technical solutions:

[0024] Embodiment 1: To solve the problems existing in the sound adjustment controller of existing electrical equipment, the following technical content is disclosed in this embodiment. A controller for intelligently adjusting the sound volume includes a main control panel 1, and the main control panel 1 includes a power supply module 2 for overall power supply to ensure the working stability. The main control panel 1 is connected to a key module 3 and a speaker unit 4. By sending different control signals generated by the key module 3 to the main control panel 1, the main control panel 1 controls the electrical equipment to enter different working modes and controls the adjustment of the volume of the speaker unit 4.

[0025] The main control panel 1 is connected to the button module 3 through GND, and the button module 3 is installed on the controller for the user to perform manual adjustment operations; the main control panel 1 and the button module 3 are connected through GND so that the loop formed by GND and the GPIO port changes the level state of the GPIO port, thereby triggering the corresponding control logic; the main control panel 1 controls the volume of the sound emitted by the speaker unit 4 by sending an increase signal and a decrease signal.

[0026] The main control panel 1 includes an MCU unit 5, and the MCU unit 5 is connected to the positive and negative poles of the power supply module 2 to ensure that the power supply of the power supply module 2 can provide stable power supply for the MCU unit 5; the main control panel 1 includes a voice module 6, and the voice module 6 is connected to the positive and negative poles of the power supply module 2 to ensure that the voice module 6 can obtain the required power supply voltage from the power supply module 2 and thus work properly; the positive pole of the power supply module 2 connects the MCU unit 5 and the voice module 6 in parallel; the MCU unit 5 ensures normal signal processing and control functions, can correctly receive and send signals to the voice module 6, thereby realizing the control of the voice module 6.

[0027] As Figure 1 shown, for the button module 3 installed on the electrical equipment, when the user presses the mode adjustment button, the button module 3 sends the button instruction information to the MCU unit 5 included in the main control panel 1. The MCU unit 5 analyzes the noise in the working mode of the electrical equipment, and then sends a control signal to the voice module 6 through the MCU unit 5.
