Embodiment

[0019] Such as figure 1 As shown, a car audio temperature calibration test device includes a temperature box 1, a fixing mechanism, a DC power supply 3, a temperature sensor and a temperature recorder. The rear of the car audio sample 4 is installed in the temperature box 1 through the fixing mechanism. There are 5 temperature sensors in total, including an upper sensor 21, a lower sensor 22, a left sensor 23, a right sensor 24 and a rear sensor 25, which are respectively arranged on the top, bottom, left, right and Rear, used to detect the real-time temperature of these locations. The temperature recorder is connected to each temperature sensor, and is used to record the real-time temperature collected by the temperature sensor to complete the temperature calibration. The temperature box 1 is provided with a wire hole, and the wire harness of the car audio sample 4 passes through the wire hole to connect to the DC power supply 3 .

Abstract

The invention relates to an automotive sound temperature calibration test device and an automotive sound temperature calibration test method. The device comprises a temperature box, a fixing mechanism, a direct-current power source, temperature sensors and a temperature recorder, wherein the rear of an automotive sound sample is arranged in the temperature box through the fixing mechanism; the temperature sensors are arranged on the periphery of the automotive sound sample; the temperature recorder is connected with the temperature sensors; and the direct-current power source is connected with the automotive sound sample. The method comprises the following steps of firstly, mounting the rear of the automotive sound sample in the temperature box; secondly, arranging the temperature sensors; thirdly, connecting the automotive sound sample to the direct-current power source; and finally, starting the temperature box and the direct-current power source, setting a test environment, lasting the state for 4 hours, and recording data of the various temperature sensors in the process by using the temperature recorder. Compared with the prior art, the automotive sound temperature calibration test device has the advantages that an automotive sound temperature calibration test is directly completed by the device; the device is easy to operate; and testing results are reliable.

Description

technical field [0001] The invention relates to the field of instrument testing, in particular to a car audio temperature calibration test device and method. Background technique [0002] In the actual vehicle equipment test, the temperature of the car audio needs to be calibrated. The conditions of the calibration test need to be in the running state of the car audio sample, and at the set temperature, real-time recording of the sample and its surrounding specific position temperature. In the current field of instrument testing, there is no device that can directly complete this test, and different instruments are needed for separate tests. The test process is cumbersome and is not conducive to reflecting comprehensive parameters. Contents of the invention [0003] The object of the present invention is to provide a car audio temperature calibration test device and method with simple operation and reliable test results in order to overcome the above-mentioned defects in ...
