Problems solved by technology
[0004] The inventors of the present invention found that in the prior art, the design value before production is usually directly used as the model parameter value of the touch vibrator. However, in the production process, due to the existence of errors, the model parameter value of the touch vibrator is often There is a certain error between the design value, or the design value itself is only a certain range of variation, and it is impossible to accurately obtain the model parameter value of the touch vibrator

The embodiment of the present invention relates to the technical field of electronic equipment, and discloses a method for solving a model parameter value of a touch vibrator, including obtaining the first value of the touch vibrator according to the actually measured voltage and current values at both ends of the touch vibrator Impedance curve: select the initial model parameter value according to the preset model parameter value of the touch vibrator, and calculate the second impedance curve of the touch vibrator according to the initial model parameter value and the impedance curve model of the touch vibrator; if the first The similarity between the first impedance curve and the second impedance curve is less than the preset threshold, then adjust the initial model parameter value until the similarity between the first impedance curve and the second impedance curve is not less than the preset threshold, and the initial model parameter value at this time As the model parameter value of the touch vibrator; the invention also discloses a touch vibrator. The method for solving the model parameter value of the touch vibrator and the touch vibrator disclosed in the present invention have the advantage that the model parameter value of the touch vibrator can be obtained more accurately.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of electronic equipment, and in particular, to a method for solving model parameter values of a touch vibrator and a touch vibrator. Background technique [0002] With the development of electronic technology, portable consumer electronic products are more and more sought after by people, such as mobile phones, handheld game consoles, navigation devices or handheld multimedia entertainment equipment, etc., generally use touch vibrators for system feedback, and Among the many touch vibrators, motors are the most widely used, such as mobile phone call prompts, information prompts, navigation prompts, vibration feedback of game consoles, etc. In order to control the vibration of the linear motor, it is necessary to know the condition of the motor system itself. [0003] For the motor system, the same motion mode has the same motion response mode, that is, the system form is the same, bu...
