Embodiment Construction

[0022] The present invention will be further described below with reference to the drawings and embodiments.

[0023] In this embodiment, a mobile phone is used as an example.

[0024] A method for detecting the state of a mobile communication device, refer to Figure 1-2 , The method includes the following steps:

[0025] Step A. Provide a mobile communication device 1, such as a mobile phone, which includes a vibrator 2 for generating a vibration response and a sound generator 3 for sounding, a signal for detecting and measuring the working voltage and working current of the vibrator 2 and processing signals The processing unit 4 and the signal generator 5 for generating excitation signals of different frequencies, the resonant frequency of the vibrator 2 is F0. In this embodiment, signal processing by the signal processing unit 4 includes measurement and calculation of signal parameters. Of course, the signal generator 5 is not limited to the mobile phone itself, and can also b...

Abstract

The invention provides a state detection method for a mobile communication device. The method comprises the following steps: providing the mobile communication device comprising a vibrator, a sounder and a signal processing unit, as well as a signal generator; detecting excitation voltage and response current of the vibrator at different frequency points during working; calculating resistance values to obtain an impedance curve; calculating resonance frequency F0', quality factor Q and curve smoothness so as to be determined as prestore data; repeating the steps so as to obtain data in different states for prestore; when the mobile communication device is in use, detecting and calculating the F0', the Q and the curve smoothness at the point and comparing the prestore data so to to identify the state; and carrying out self-adaptive adjustment through resending corresponding drive signals. Compared with the prior art, the detection method is simple and practical, and the mobile communication device adopting the method has the advantages of adaptivity and excellent performance.

Description

【Technical Field】 [0001] The invention relates to a state detection method, in particular to a state detection method used in a portable mobile communication device with a vibration function. 【Background technique】 [0002] With the development of mobile communication technology, portable mobile devices such as mobile phones are also constantly updated, and people have more and more functional requirements for related products. Not only that, for office workers, especially those with a lot of business, they also pursue practical and comfortable use of related products in addition to functional requirements. [0003] Related technology Mobile communication devices such as mobile phones include vibrators and music players, but they do not have the function of self-environmental state detection, and cannot detect the impedance of their own state, so that related technology products can only be single when receiving incoming calls. Vibrate and play music as a reminder. [0004] However...
