PRODUCT DESCRIPTION Smart Bluetooth Speaker/Sound Testing and Certification BQB,WIFI,SIRIM,KC,India BIS,SASO,SABER,PVOC,SONCAP, COC, E-Mark A new competitive curtain for smart speakers has slowly begun. In addition to volume growth in the future, the entire industry has also begun to enter a new stage of industrial ecological construction. From a longer-term perspective, among smart speaker head manufacturers, regardless of whether they are ecologically open or closed, whether industrial upgrading is fast or slow, what consumers can look forward to is how much ecosystem and social value they can create. Smart speakers refer to audio equipment that has a built-in Bluetooth chip and uses Bluetooth connections to replace traditional wire connections. It can achieve the purpose of convenience and speed by connecting to Bluetooth playback devices such as mobile phones, tablets, and laptops. Testing requirements for Bluetooth speaker test reports to enter Tmall: Product quality inspection reports can comprehensively and objectively reflect the quality information of the product, and are generally completed by a third- party professional inspection agency that is independent of both supply and demand parties. 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 manufacturer on the products it produces is called the supplier (supplier) inspection report. Due to related interests, it is not qualified to issue fair data to the society. Smart Bluetooth Speaker Sound Testing Certification BQB WIFI SIRIM KC India BIS SASO SABER PVOC SONCAP COC E-Mark 0 In addition to the regular evaluation of wireless Bluetooth speakers, for consumers, what is more important is the performance of wireless Bluetooth speakers. This part of the test is mainly judged through detailed scores. The test items are also multi-faceted, and each link is Closely related to users’ daily experience. First, compatibility evaluation. We will select mainstream front-end platforms: PC, Android, iOS, and Windows Phone 7 to conduct pairing tests on each mobile Bluetooth speaker. Firstly, we will see whether it can be successful, and secondly, we will look at the complicated process of pairing. Look at the number of functions implemented by the mobile Bluetooth speaker. Second, transmission distance test. We will simulate testing with and without physical barriers. Physical barriers are mainly doors and walls, and horizontally compare the wireless transmission capabilities of each participating product. Third, the anti-interference ability test. Simulate the user's actual usage environment and test situations where radio signals are more complex, such as whether routers, other 2.4G devices and Bluetooth devices can successfully connect in an environment shared by each other. Fourth, battery life test. We will first find a decibel level for commonly used volume, and let the volume level of each participating product reach the same decibel level for continuous and uninterrupted battery life testing to test its true battery life. Fifth, subjective listening test (call quality and music playback quality). Due to the special functionality of mobile Bluetooth speakers, we will measure them according to conventional sound quality standards and consider aspects such as distortion, resolution, and low frequency to obtain a true sound quality score. In addition, we will also compare the call quality of Bluetooth speakers.

Veterinary B-ultrasound is a device that uses high-frequency sound waves to generate images inside animals. These images can provide detailed information about the animal's health and reproductive status, such as fetal development, the condition of the ovaries and uterus, and more. By using veterinary B- ultrasound, farmers can more accurately identify breeding problems, take necessary measures to solve the problem, and improve breeding efficiency. In actual farm applications, veterinary B-ultrasound is usually used in the following aspects: Detection of early pregnancy: Through animal B-ultrasound, fetuses can be detected in pigs, cattle and other animals in the early stages of pregnancy, so that pregnancy can be determined earlier and problems such as embryonic death or uterine inflammation can be avoided. Monitor fetal development: Regularly monitor the development of the fetus to ensure its healthy growth. This can help ranchers take action when necessary, such as increasing nutrition or adjusting the feeding environment. Check the ovaries and uterus: Through veterinary B-ultrasound, the condition of the ovaries and uterus can be checked to determine the cause of reproductive problems. This could help ranchers take targeted measures, such as using drugs or surgery, to address the problem. Disease diagnosis: used to diagnose some common animal diseases, such as metritis or mastitis, etc. With prompt diagnosis and treatment, the impact of these problems on animal health and reproduction can be avoided. The application of veterinary B-ultrasound in farms has the following advantages: Improve breeding efficiency: Identify breeding problems more accurately and take necessary steps to fix them. This can improve reproductive efficiency and reduce problems such as embryonic death and uterine inflammation. Reduce economic losses: Through timely diagnosis and treatment, the impact of some common diseases on animal health and reproduction can be avoided, thereby reducing economic losses. Provide accurate reproductive data: Veterinary B-ultrasound can provide accurate reproductive data, including the number and development of fetuses. These data can help ranchers make more accurate breeding plans, improve production efficiency and economic benefits.
