Abstract

The invention relates to the technical field of bone conduction earphones and touch force feedback, in particular to a multifunctional piezoelectric bone conduction earphone and touch force feedback system integrated with glasses. The system comprises a glasses frame base body, an integrated piezoelectric driving and force feedback signal processing circuit board, a power supply module, a piezoelectric material, an upper electrode layer, a lower electrode layer and a flexible circuit, wherein the integrated piezoelectric driving and force feedback signal processing circuit board and the power supply module are arranged at the roots of glasses legs, the piezoelectric material is fixed in a groove of one glasses leg, the upper electrode layer and the lower electrode layer are coated on the surface of the piezoelectric material, and the flexible circuit is connected with the electrode layers and the circuit board. The circuit board receives audio signals and applies voltage signals to the electrode layers of the piezoelectric material. By the aid of inverse piezoelectric effect, the piezoelectric material generates vibration identical to sound electric signals in frequency so as to drive the glasses legs to vibrate together, vibration of the glasses legs is transmitted into a human body face contacting with the glasses legs, sound is sensed by auditory nerves of a human body through bone conduction, and accordingly sense of hearing is generated. When the piezoelectric material is subjected to external force, corresponding induction electrical signals are generated and are processed by the circuit board to corresponding feedback touch signals which are used for achieving control functions of function selection, switching and the like.

Description

technical field [0001] The invention relates to the technical field of bone conduction earphones and touch force feedback, in particular to a multifunctional piezoelectric bone conduction earphone and touch force feedback system integrated with glasses. Background technique [0002] Glasses are also a tool commonly used by modern people. They are not only used to correct vision, but also reflect the wearer's identity, social status, ideas, hobbies, etc. in a tangible way through the combination of material and art. According to relevant statistics, as of 2008, there were 260 million people with myopia in China; in addition, eye diseases such as hyperopia, amblyopia, and astigmatism require wearing glasses, and casual glasses such as sunglasses, photochromic glasses, and even lensless glasses are becoming more and more popular among people. favorite. [0003] With the advancement of science and technology and the improvement of people's living standards, earphones have becom...
