The new competition curtain of smart speaker has been gradually unfolded. In addition to the growth of volume in the future, the whole industry has also begun to enter a new stage of industrial ecological construction. From a longer-term perspective, consumers are more expected to see how much ecological circle and social value can be created by smart speaker head manufacturers, no matter whether they go ecological opening or closing, whether industrial upgrading is fast or slow.
Smart speaker refers to the audio equipment with built-in Bluetooth chip, which replaces the traditional wire connection by Bluetooth connection, and achieves the purpose of convenient and fast by connecting with Bluetooth playing devices such as mobile phone tablet computer and notebook. Requirements for Bluetooth speaker test report to tmall: the product quality inspection report can comprehensively and objectively reflect the product quality information, which is generally completed by a third-party professional inspection organization independent of the supply and demand sides. The third-party professional inspection institutions are relatively independent and impartial, and are qualified to issue fair data (test reports) to the society. The inspection report made by the production enterprise for its own products is called the Party (Supplier) inspection report. Due to the interest, it is not qualified to issue fair data to the society.
Intelligent Bluetooth speaker detection project
In addition to the regular evaluation of wireless Bluetooth speaker, for consumers, the more important thing is the performance of wireless Bluetooth speaker. This part of the test is mainly evaluated by detailed scores. The test items are also various, and each link is closely related to the user's daily experience.
First, compatibility evaluation. We will select the mainstream front-end platforms: PC, Android, IOS, windows Phone7 to test the pairing of each mobile Bluetooth audio. First, we will see whether it is successful, and then we will look at the complex process of pairing. Look at the number of mobile Bluetooth audio functions.
Second, transmission distance test. We will simulate the physical barrier and no physical barrier for testing. The physical barrier is mainly door and wall. The wireless transmission capacity of each participating product is compared horizontally.
Third, anti-interference ability test. Simulate the user's actual use environment, test the wireless signal complex situation, such as the router, other 2.4G devices and Bluetooth devices can connect successfully.
Fourth, endurance test. First of all, we will find a decibel of the commonly used volume, so that the volume level of each product participating in the evaluation can reach a uniform decibel, and the continuous continuous endurance test will be conducted to test its real endurance time.
Fifth, subjective listening test (call quality and music playing quality). Due to the special functionality of 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 the true sound quality score. In addition, we will compare the call quality of Bluetooth audio.
Smart Bluetooth speaker Certification Project
Intelligent Bluetooth speaker detection and certification process
