Abstract

A disclosed electronic north-seeking voice broadcast apparatus comprises a control module connected with a magnetic-resistance sensing module, a liquid crystal display module, a keyboard, a real-time clock module and a voice broadcast module. The electronic north-seeking voice broadcast apparatus employs the magnetic-resistance sensing module for detecting terrestrial magnetism, avoids the problems that a conventional mechanical compass is bad in portability and low in sensitivity and the service life is reduced because of mechanical wearing, especially is diversified in functions, is capable of seeking north and also is capable of timing. A measured northerly azimuth angle is digitally displayed through the liquid crystal display module and is accurate, and also the apparatus possesses voice broadcast function, and facilitates the elderly with bad eyesight to use the apparatus.

Description

technical field [0001] The invention belongs to the technical field of navigation measurement equipment, and in particular relates to an electronic north-guiding voice broadcast device. Background technique [0002] In daily life, identifying directions is the basic way for people to go out and find their destinations. Sinan, one of China's four great inventions, now looks bulky. Although the traditional mechanical compass has a simple structure, due to mechanical inherent factors, the compass has poor portability, low sensitivity, and mechanical wear will reduce its service life; especially the function is single, and it is vulnerable to external light when reading the compass. Misinterpreted by factors. Contents of the invention [0003] The purpose of the present invention is to provide an electronic northerly voice broadcast device, which can realize the measurement of northerly azimuth, and has two modes of liquid crystal display and voice broadcasting of northerly ...
