Audiowell Launch open type ultrasonic transducer with φ8 class


With the rise of artificial intelligence technology, various industries have higher and higher requirements for components, especially the pursuit of "quality". Recently, Audiowell launched Mini open type ultrasonic transducer, which is 8 mm in size. It can optimize the structure and ensure the performance. It is suitable for directional sound production, distance measurement and other applications.

Application scheme of directional speaker 

The signal transmitted by the traditional sound system is spherical wave, which will be transmitted in all directions, and there will be obvious attenuation phenomenon in the transmission process. The sound system with open type ultrasonic sensor can realize directional long-distance transmission, and almost no attenuation occurs in the transmission process, so as to ensure that the audience can hear clear, complete and high-quality audio. Directional speaker technology will gradually become the preferred application scheme for high-quality audio transmission in more fields.

Distance measurement applications

Another main function of the open type ultrasonic sensor is to measure the distance. It measures the distance between the sensor and the obstacle through the time difference of ultrasonic flight in the air. Compared with the traditional measurement methods, ultrasonic ranging has the advantages of stable performance, high accuracy and non-contact measurement. In practical application, ultrasonic ranging technology has been very common. Recently, there is also a demand in the high requirement security field. Ultrasonic ranging technology is used to monitor whether the installation position of smoke alarm is appropriate or whether it is blocked.

【Other application scenarios】

01 - Smart Home:

It is installed on the door and window. When there is no one at home and the door and window are closed, the home intrusion prevention system will record the intrusion time and send out the alarm signal.

02 - Intelligent parking:

It is installed on the top of the parking space to detect the occupancy of the parking space, which can effectively improve the management efficiency of the parking lot, and facilitate the car owners to find the parking space quickly

04 - Height measurement:

The accurate distance measurement by ultrasonic induction ensures that the accuracy of each height measurement reaches millimeter level, and the daily height measurement reaches the level of medical body measurement.
