Problems solved by technology

[0006] However, there is at least one problem in the prior art of providing tactile feedback based on audio: when the battery power of a hand-held mobile device drops, the tactile feedback provided by the hand-held mobile device will also decrease with the power drop, and cannot maintain the same or similar tactile effects

Embodiment approach ， 1

[0047] Step S630: Adjust the gain of the sound signal or its derivative signal according to the power detection result, and output a tactile compensation signal accordingly, wherein the tactile compensation signal is used to compensate the tactile effect. This step can be done by figure 1 The touch compensation circuit 130 is implemented, and includes at least two implementations. One implementation is: adjusting the gain of the sound signal according to the power detection result to generate a gain adjustment signal; and generating a filter based on the gain adjustment signal. A signal (such as a low-pass filtered signal) is used as the touch compensation signal. Another embodiment is: generating a filter signal (such as a low-pass filter signal) according to the sound signal; and adjusting the gain of the filter signal according to the power detection result to generate the touch compensation signal.

[0048] By virtue of the above, and see Figure 7 , this embodiment may ...

Abstract

The invention discloses a voice frequency device with a touch compensation function and a voice frequency utilization method. The voice frequency device with the touch compensation function can compensate a touch effect according to an electricity detection result and a voice signal and comprises a voice frequency generation circuit which is used for outputting the voice signal, an electricity detection circuit which is used for detecting electricity of a power source to generate the electricity detection result and a touch compensation circuit which is in coupling connection with the voice frequency generation circuit and the electricity detection circuit; the touch compensation circuit is used for adjusting the voice signal or the gain of a derivation signal of the voice signal according to the electricity detection result and outputting a touch compensation signal; the touch compensation signal is used for compensating the touch effect.

Description

technical field [0001] The invention relates to an audio device and an audio use method, in particular to an audio device with a touch compensation function and an audio use method. Background technique [0002] In recent years, in order to enhance the user experience of consumers, many products have introduced tactile design, such as the vibration feedback of the game handle, the tactile feedback of the touch screen, and the tactile design of medical or learning products. Among the many tactile design fields, there are also tactile designs for audio. For example, when a handheld mobile device is playing music, it can provide corresponding tactile feedback with the rhythm of the music, so that users can better integrate into the music situation and Enjoy it, related previous technologies can refer to the following documents: [0003] US patents (patent numbers: 6703550, 7979146 (also disclosed in European Patent Office application EP2166432), 8441437 (also disclosed in Pate...
