basic introduction

The new competition curtain of smart speakers has been slowly launched. In addition to the increase in volume in the future, the entire industry has also begun to enter a new stage of industrial ecological construction. From a longer-term perspective, among the manufacturers of smart speaker heads, no matter whether they are ecologically open or closed, whether the industrial upgrade is fast or slow, how much ecological circle and social value can create, is what consumers are more worth looking forward to.

Smart speaker refers to the built-in Bluetooth chip, which replaces the traditional audio equipment with Bluetooth connection, and connects with Bluetooth playback devices such as mobile phones, tablets and notebooks to achieve the purpose of convenience and speed. Bluetooth speaker test report into Tmall's test requirements: product quality inspection report can comprehensively and objectively reflect product quality information, and is generally completed by a third-party professional inspection agency independent of supply and demand. The third-party professional inspection agencies are relatively independent and impartial, and are qualified to issue fair data (test reports) to the society. The inspection report made by the manufacturing enterprise on the products it produces is called the party (supplier) inspection report. Due to the interest, it is not qualified to issue fair data to the society.

Smart Bluetooth speaker testing project

In addition to the conventional evaluation of wireless Bluetooth speakers, for consumers, the more important thing is the performance of wireless Bluetooth speakers. This part of the test is mainly judged by detailed scores. The test items are also multi-faceted, every link is It is closely related to the user's daily experience.

First, compatibility evaluation. We will select mainstream front-end platforms: PC, Android, iOS, Windows Phone7 to pair test each mobile Bluetooth audio, first to see whether it is successful, and second to look at the complex process of pairing. Look at the number of functions implemented by mobile Bluetooth audio.

Second, the transmission distance test. We will simulate the test with and without physical barriers. The physical barriers are mainly doors and walls, and the wireless transmission capabilities of each participating product are compared horizontally.

Third, the anti-interference ability test. Simulate the user's actual use environment, and test the more complex radio signal scenarios, such as whether the router, other 2.4G devices and Bluetooth devices share the environment to successfully connect.

Fourth, the battery life test. We will first find a decibel number for the commonly used volume, so that the volume level of each participating product reaches a uniform decibel number for continuous uninterrupted endurance testing to test its true endurance time.

Fifth, subjective listening test (call quality and music playback quality). Due to the special functionality of the mobile Bluetooth audio, we will measure it according to the standard of conventional sound quality, and consider the distortion, resolution, low frequency and other aspects to obtain a true sound quality score. In addition, we will also compare the call quality of Bluetooth audio.

Smart Bluetooth speaker certification project

Smart Bluetooth speaker testing and certification process

1. Information on product introduction (instructions, specifications, etc.)

2. Confirm the testing purpose and project requirements

3. Fill in the test application form (including company information and product necessary information)

4. According to requirements and send samples

5. After receiving the sample, arrange the cost for sample testing

6. Detect relevant data, prepare draft report to confirm whether the information is correct

7. After the confirmation is complete, the seal is issued and the official report is issued

8. Send original report and issue
