Title:
ULTRASONIC LOSS-PREVENTION TRACKER AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/082450
Kind Code:
A1
Abstract:
An ultrasonic loss-prevention tracker (02), comprising at least one ultrasonic transmitting unit (4), at least one ultrasonic receiving unit (5), a processor (2) and a battery (6), which are integrated in a shell (1), wherein the processor (2) is connected to the ultrasonic transmitting unit (4) and the ultrasonic receiving unit (5), and the battery (6) supplies power to a component in the loss-prevention tracker (02). Distance measurement and angle measurement can be realized by using the ultrasonic transmitting unit (4) and the ultrasonic receiving unit (5) in cooperation with a microphone and loudspeaker of a mobile phone (01), such that distance information and direction information are provided, thereby realizing accurate near-distance search; moreover, the ultrasonic transmitting unit (4) and the ultrasonic receiving unit (5) are arranged inside the shell (1), preventing damage to the ultrasonic transmitting unit (4) and the ultrasonic receiving unit (5), and improving the degree of integration of the loss-prevention tracker (02), thereby facilitating usage and realizing an aesthetic design; and by means of the design of a sound-transmitting region (11), providing a sound-transmitting hole or using an ultrasonic low-attenuation material, ultrasonic signals are not greatly weakened by the shell, thereby improving positioning precision and enlarging the accurate search range.
