State detection method for mobile communication device

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...

Problems solved by technology

[0003] Mobile communication devices such as mobile phones in the related art 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 the products of the related technology can only be single when receiving an incoming call. Vibrate and play music for reminders

[0004] Yet if the mobile phone of related art is placed on the harder desktop, the vibration of mobile phone can make mobile phone and desktop have heavier continuous collision when receiving incoming call, send bigger noise; When receiving a call, the mobile phone will not hear the music reminder because the speaker is covered by the pocket, so it may miss some important calls, etc. The above-mentioned phenomena make the products of related technologies poor in adaptability, which seriously affects the user's understanding of related technologies.
