Smartwatch compass function test equipment

Abstract

The invention discloses smartwatch compass function test equipment. The equipment comprises a shielding box, a test box, an electric control box, an upper coil, a lower coil, a carrier and an electriccontrol device, wherein the test box and the electric control box are enclosed in the shielding box; the upper coil, the lower coil and the carrier are arranged in the test box; the electric controldevice is arranged in the electric control box; the electric control device is electrically connected with the upper coil, the lower coil and the carrier; after electrification, a simulation magneticfield can be formed between the upper coil and the lower coil; the carrier is obliquely arranged in the test box to ensure that the induction center of an electronic compass clamped in the carrier islocated at the central position of the simulation magnetic field; and the magnetic field direction of the simulation magnetic field is changed along with the change of the current directions in the upper coil and the lower coil, so as to realize the test of an indication function, in a south and north pole magnetic field simulated by the simulation magnetic field, of the electronic compass. The equipment is simple in structure and convenient to use, and is capable of effectively improving the test correctness.

Description

technical field [0001] The invention relates to a testing device, in particular to a smart watch compass function testing device. Background technique [0002] With the continuous development of science and technology, electronic compass has been widely used in intelligent mobile electronic devices such as mobile phones, tablet computers, GPS, game consoles and watches. The electronic compass is generally integrated by the magnetic induction part and the processing circuit. Its manufacturing process is quite complicated, involving hundreds of processing steps. Any irregularity in any process will affect the performance of the electronic compass. In actual use, the compass of a mobile electronic device needs to accurately perceive the magnetic field direction and strength signal of the specific location, especially whether the performance of the electronic compass applied to a smart watch is particularly important, because in outdoor sports and field environments, the electro...

AI Technical Summary

Problems solved by technology

In the existing compass function tests for smart watches, multiple groups of simulated magnetic fields are set along the directions of the X, Y, and Z axes, and the corresponding tests are realized by moving the electronic compass to be tested in the corresponding magnetic fields. The structure of the equipment is relatively complex, the test efficiency is relatively low, and the driving motor has a certain interference to the magnetic field, which affects the stability and accuracy of the test.
