Touch prompting device and wireless earphone

Abstract

The invention relates to a touch prompting device and a wireless earphone. The touch prompting device comprises a power drive, a first magnet, a second magnet and a touch part, wherein the power drive is connected with electromagnets in the first and second magnets and used for generating an electromagnetic field through driving the electromagnets according to trigger signals; the first magnet is fixed in a shell, and the second magnet repeats a reciprocating motion of approaching and keeping away from the first magnet according to the polar variation of a self electromagnetic field or the polar variation of the electromagnetic field of the first magnet; and the touch part is connected with the second magnet, protrudes out of the shell and touches the skin of a user according to the reciprocating motion of the second magnet. The touch prompting device and the wireless earphone provided by the invention can be worn by users and can also be arranged on various electronic equipment which can be worn by the users; the touch prompting device prompts the users in a skin touching manner and can be used for solving problems which are not easily found out by users in a vibration prompting manner; and the triggered vibration force is small, the service life of the electronic equipment cannot be shortened when the touch prompting device is arranged on the electronic equipment, and the touch prompting device is energy-saving and environmental-friendly.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to the technical field of mobile terminal accessories, in particular to a tactile notification device and a wireless earphone. Background technique [0002] Currently, consumer electronic devices generally have a reminder function, for example, an alarm clock reminder, a text message notification reminder, an incoming call reminder, and the like. The reminder function is usually realized by sound or vibration of a vibrator. Wearable electronic devices such as watches can also be configured with vibrators to provide reminders. [0003] The vibrator consists of a tiny electric motor with a cam (also known as an eccentric). The principle of vibration is as follows: the eccentric motor is an ordinary motor with a cam installed on the head, and the center of gravity of the cam is not on the rotating shaft of the motor. When rotating, the cam makes a circular motion to ...

Problems solved by technology

[0004] However, frequent vibration will lead to loose parts inside electronic equipment, poor electrical contact, resulting in high power consumption and shortening the service life of electronic equipment; and vibration and alarm clock reminders are easy to disturb others
