Abstract

The invention belongs to the electronic technical field, relates to a wireless positioning device used for looking for a lost article, in particular to a loss-proofing sounder, aiming ate solving the problem that a lot of time and vigour are taken to look for the lost article while the probability that the lost article is found is extremely low. The sounder is composed of a handheld finding device, a plurality of electronic tags and a built-in antenna in the handheld finding device. By adopting the device, the technical problem can be effectively solved.

Description

technical field [0001] The invention belongs to the field of electronic technology, and relates to a wireless positioning device for finding lost objects, in particular to an anti-lost sounder. Background technique [0002] In daily life, lost objects often happen. However, many lost objects are not really lost, but people forget in a certain place, and such objects may be found inadvertently in the future. When people urgently want to get such objects due to certain needs, searching becomes a kind of hard work. People search aimlessly, which not only wastes a lot of time and energy, but also has a very low chance of rediscovering lost objects. . Contents of the invention [0003] The technical problem to be solved by the present invention is that it takes a lot of time and energy to find the lost object, and at the same time, the probability of its being found is very low, and an anti-lost sounder is provided to solve the above problem. [0004] The present invention so...
