Embodiment 1

[0042] Embodiment 1 A sound volume adjustment method provided by an embodiment of the present invention, refer to figure 1 As shown, the method includes:

[0043] 101. After the wheel speed sensor measures the vehicle speed and sends the vehicle speed to the instrument combination module through the network device, receive the vehicle speed sent by the instrument combination module.

[0044] 102. According to the vehicle speed, generate a corresponding relationship between the vehicle speed and the sound volume.

[0045] 103. According to the corresponding relationship between the vehicle speed and the sound volume, adjust the sound volume.

[0046] The embodiment of the present invention provides a method for adjusting the sound volume. Through the hard wire connected to the instrument combination module, the vehicle speed measured by the wheel speed sensor and sent to the field bus network is obtained, so that the sound volume can be adjusted without connecting the field bu...

Embodiment 2

[0047] Embodiment 2 is another car audio volume control method provided by the embodiment of the present invention. This method is applied when the car audio of the vehicle cannot be connected to the field bus network and the vehicle has no car sensor. Specifically, refer to figure 2 As shown, the method includes:

[0048] 201. The wheel speed sensor measures the vehicle speed of the vehicle, and generates a vehicle speed signal, where the vehicle speed signal includes the vehicle speed.

[0049] Specifically, the wheel speed sensor generates a vehicle speed signal after measuring the vehicle speed, and the vehicle speed signal includes the vehicle speed.

[0050] Due to the different types of wheel speed sensors, the signal types of the vehicle speed signal output by the wheel speed sensor include magnetoelectric AC signals, Hall digital signals and photoelectric digital signals. If the magnetoelectric AC signal is used, it is necessary to convert the magnetoelectric AC sig...

Embodiment 3

[0095] Embodiment 3 is an electronic device 3 provided by the embodiment of the present invention, refer to image 3 As shown, the electronic device 3 includes:

[0096] The receiving unit 31 is used to receive the vehicle speed sent by the instrument combination module after the wheel speed sensor measures the vehicle speed of the vehicle and sends the vehicle speed to the instrument combination module through the network device;

[0097] A processing unit 32, configured to generate a correspondence between vehicle speed and sound volume according to the vehicle speed;

[0098] The adjusting unit 33 is used for adjusting the sound volume according to the corresponding relationship between the vehicle speed and the sound volume.

[0099] With reference to the second aspect, in a first possible implementation manner, the receiving unit 31 is specifically configured to:

[0100] Receive the vehicle speed sent by the instrument combination module through the hard wire connected...

Abstract

The invention discloses a loudspeaker box volume adjusting method and an electronic device, and belongs to the field of automobile electronics. The method comprises the steps that after a wheel speed sensor measures the speed of an automobile and the speed of the automobile is sent to an instrument combining module through a network device, the automobile speed sent by the instrument combining module is received; the corresponding relation between the speed of the automobile and the loudspeaker box volume is generated according to the speed of the automobile; the loudspeaker box volume is adjusted according to the corresponding relation between the speed of the automobile and the loudspeaker box volume. The automobile speed measured and sent to a field bus network by the wheel speed sensor is obtained through a rigid line connected with the instrument combining module, the speed of the automobile can be obtained under the condition that a loudspeaker box is not connected with the field bus network and an automobile speed sensor is not arranged, the volume of the loudspeaker box is adjusted according to the automobile speed, and therefore cost is reduced.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to a sound volume adjustment method and equipment. Background technique [0002] With the popularization of car audio, more and more people use car audio in the process of driving, but in the process of driving, the noise of the vehicle itself and the surrounding environment at high speed will affect the use of car audio, so it is necessary to provide The invention relates to a sound volume adjusting method, which adjusts the sound volume when the vehicle is running at high speed. [0003] The prior art provides a method for adjusting audio volume, specifically: acquiring the vehicle speed measured by a vehicle speed sensor, and adjusting the audio volume according to the vehicle speed. The prior art also provides a method for adjusting the sound volume, specifically: acquiring the vehicle speed in the field bus network, and adjusting the sound volume according to the vehicle ...
