Embodiment 1

[0044] figure 1 It is a block diagram of an audio collection tooling of an embodiment of the present invention, see figure 1 , the audio collection tool 10 includes: a micro control unit 101, an audio collection microphone 102, an identification scanning unit 103, a communication unit 105 and a storage unit 104;

[0045] The identification scanning unit 103 is used to scan the one-dimensional code information uniquely identifying the speaker carried on each speaker to be shipped, and send the one-dimensional code information of each speaker to the micro control unit 101;

[0046] Audio collection microphone 102 is used to collect the sound signal when each loudspeaker to be shipped from the factory plays a predetermined sweep tone in the silent room, and sends the sound signal to the micro control unit 101;

[0047] The micro control unit 101 is used to compare the sound signal with the standard sweep tone signal stored in the storage unit 104 after receiving the sound signal...

Embodiment 2

[0052] figure 2 It is a block diagram of an audio collection tooling according to another embodiment of the present invention, combined below figure 2 The structure of the audio collection tool is described in more detail.

[0053] see figure 2 , the audio collection tooling 20 includes: an audio collection microphone, namely figure 2 The MIC shown in , identification scanning unit 201 , micro control unit 202 , communication unit 203 , storage unit 204 , audio collection button 205 , LCD screen 206 , speaker 207 and analog-to-digital conversion unit 208 .

[0054] The audio collection button 205 is an interface between the audio collection tool and the user, and is used to receive the audio collection instruction input by the user, and send the audio collection instruction to the micro control unit 202, and the micro control unit 202 controls the audio collection when receiving the audio collection instruction The microphone enters the working state.

Embodiment 3

[0069] image 3 It is a flowchart of an audio collection method in an embodiment of the present invention, see image 3 , the audio collection method in this embodiment includes the following steps S301-S304:

[0070] S301, scanning the one-dimensional code information uniquely identifying the speaker carried on each speaker to be shipped;

[0071] S302, collecting sound signals when each speaker to be shipped out of the factory plays a predetermined sweep tone in the silent room;

[0072] S303, comparing the sound signal of the speaker to be shipped with the standard sweep tone signal, if the sound signal of the speaker to be shipped is inconsistent with the standard sweep tone signal, then determine that the speaker to be shipped is unqualified; if the sound signal of the speaker to be shipped is not consistent with the standard If the scanning tone signal is consistent, it is determined that the speaker to be shipped is qualified;

[0073] S304. Send the sound signal of ...

Abstract

The invention discloses an audio acquisition tooling, a method and a cloud server. The tooling comprises an identification scanning unit, an audio acquisition microphone, a micro-control unit and a communication unit, wherein the identification scanning unit is used for scanning one-dimensional code information uniquely for identifying a loudspeaker carried on each loudspeaker to be delivered; the one-dimensional code information is sent to the micro-control unit; the audio acquisition microphone is used for acquiring a sound signal of each loudspeaker to be delivered while pre-determined frequency sweeping sound is played in a quiet room; the micro-control unit compares the sound signal with a standard frequency sweeping sound signal stored in a storage unit; if not same, the loudspeaker to be delivered is not qualified; otherwise, the loudspeaker to be delivered is qualified; and the sound signal and the one-dimensional code information of the qualified loudspeaker are sent to a cloud side through the communication unit, such that the cloud side stores the sound signal as a standard audio flow. According to the audio acquisition tooling, the method and the cloud server disclosed by the invention, whether the loudspeaker is qualified or not is determined by acquisition of the sound signal of the loudspeaker; when the loudspeaker is qualified, the sound signal of the qualified loudspeaker is sent to the cloud side, such that the cloud side stores sound signals of a lot of qualified loudspeakers; and basis is provided for machine vibration test of audio output equipment.

Description

technical field [0001] The invention relates to the technical field of audio equipment testing, in particular to an audio collection tool, method and cloud server. Background technique [0002] Current factory test specifications for audio output devices (for example, televisions) require that a "shock" test be performed on the television. The camera shock test is a test to determine whether the overall structure of the TV will produce abnormal noise due to sound resonance when the speaker in the TV plays a test sound. [0003] The camera shake test in the prior art is basically judged by human subjectively, and the test is completed by the human ear. The efficiency is low and the accuracy is poor, and it is easy to cause TVs with "shock" noises to flow into the market and affect the corporate image. Therefore, there is an urgent need for a new machine-shock test scheme to reduce the cost of testing manpower and improve the efficiency and accuracy of machine-shock testing. ...
