Abstract

The invention discloses a circuit and a device for generating tactile feedback by using audio. According to one embodiment, the circuit comprises a first transistor and a second transistor, a processor, an audio power amplifier, a memory and a linear motor, the memory is used for storing audio signal files; the processor is electrically connected with the memory, reading reads the an audio signalfile stored in the memory; then, carrying out the audio is decoding decoded on the audio signal file to obtain an analog audio signal; wherein t. The processor is electrically connected with the audiopower amplifier, the processor outputs analog audio signals to the audio power amplifier, the audio power amplifier is electrically connected with the a linear motor, the audio power amplifier performs power amplification on the analog audio signals, and then the amplified analog audio signals are used for driving the linear motor to vibrate. According to the embodiment, the linear motor is driven by the audio signal file to vibrate, accurate tactile feedback is generated, the efficiency is high, and the cost is low.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to a circuit for producing tactile feedback, and in particular to a circuit and equipment for producing tactile feedback by using audio. Background technique [0002] Now more and more electronic devices start to provide user feedback, which not only conveys information to users, but also improves user experience. The most commonly used feedbacks are acoustic feedback and optical feedback. Tactile feedback is a new type of feedback technology that is different from auditory feedback and visual feedback. Haptic feedback technology enables products to communicate with users flexibly and freely in environments with loud sounds and limited light, or in silent environments. [0003] In the prior art, an integrated tactile driver is usually used to drive a linear motor to generate tactile feedback, for example, tactile drivers of models DRV2604 and DRV2605. In order to ge...
