Obstacle meeting ultrasonic alarm mobile phone

Abstract

The invention discloses an obstacle meeting ultrasonic alarm mobile phone. The mobile phone is provided with an integrated single-chip, a mobile phone left ultrasonic transmitter, a mobile phone right ultrasonic transmitter, a mobile phone head ultrasonic transmitter, a mobile phone left frequency signal drive amplifying circuit, a mobile phone right frequency signal drive amplifying circuit, a mobile phone head frequency signal drive amplifying circuit, a mobile phone left ultrasonic receiver, a mobile phone right ultrasonic receiver, a mobile phone head ultrasonic receiver, a mobile phone left ultrasonic received signal amplifier, a mobile phone right ultrasonic received signal amplifier, a mobile phone head ultrasonic received signal amplifier and a temperature sensor. An ultrasonic sensor is provided with near, middle and far alarm modes. The default alarm distances are 0.5m, 1m and 3m. When an obstacle is within an alarm range, an image appears in a mobile phone screen and / or a mobile phone loudspeaker sounds to give out alarm information. Various accidents are effectively prevented when a user watches the mobile phone.

Description

Technical field: [0001] The invention belongs to the technical field of mobile terminals, and relates to an obstacle-encounter ultrasonic alarm mobile phone with three alarm modes of near, medium, and long distances (the default alarm distances are 0.5m, 1m, and 3m respectively), and the default alarm distance can be adjusted at any time. Background technique: [0002] With the development of mobile phone integration, technology and intelligence, the functions of mobile phones have extended from traditional voice messages to all aspects of life such as video calls, voice chats, road navigation, ordering and shopping, and people's lives are inseparable from mobile phones.

Problems solved by technology

However, there has not been a mobile phone that uses ultrasonic waves to measure the distance between the mobile phone user and obstacles such as people, cars, trees, etc.

Ultrasound is a sound wave with a frequency higher than 20,000 Hz. It has good directionality, strong penetrating ability, and is easy to obtain concentrated sound energy. It can be used for distance measurement, speed measurement, cleaning, welding, gravel, sterilization, etc., based on Ultrasonic sensors developed by ultrasonic characteristics are widely used in medicine, military, industry, agriculture and other fields, especially in distance measurement. Ultrasonic sensors have a wide range of applications. However, there is no integrated ultrasonic sensor to remind mobile phone users of the surrounding environment. dangerous cell phone
