Embodiment Construction
[0039] The present invention provides a charger, a mobile terminal, a charger detection system and a detection method thereof. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0040] see figure 1 , which is a circuit diagram of the charger of the present invention. Such as figure 1 As shown, the charger provided by the present invention includes a charging module 100 , an oscillation module 200 , a voltage matching module 300 , and a charging output interface 400 connected in sequence. Wherein, the charging module 100 is used to generate a charging voltage, which is generally a 5V DC voltage. The oscillation module 200 is used to generate a fixed...

The invention discloses a charger, a mobile terminal, a charger detection system and a detection method thereof. The charger comprises a charging output interface, a charging module, a vibration module and a voltage matching module, wherein the charging module, the vibration module, the voltage matching module and the charging output interface are sequentially connected. The mobile terminal comprises a charging input interface and a baseband controller; and the charging input interface is connected with the baseband controller. According to the charger, the mobile terminal, the charger detection system and the detection method thereof disclosed by the invention, the frequency of a fixed-frequency signal can be detected through the mobile terminal, and whether the frequency exists or not is found in a frequency managing module; only if the frequency exists, a charging function is started, so that a non-standard-configuration charger cannot charge the mobile terminal; and various charging safety problems caused by charging through using the non-standard-configuration charger are avoided, and the charging is safer and more reliable.
Description
technical field [0001] The invention relates to the charging technology of electronic devices, in particular to a charger, a mobile terminal, a charger detection system and a detection method thereof. Background technique [0002] As the most commonly used accessory for mobile terminals, chargers must be reliable and safe. However, due to the simple design of the standard charger circuit of most mobile terminals and the universal charging interface, users can use non-standard chargers in daily use. charger to charge the mobile terminal. Because there are generally differences in electrical parameters between non-standard chargers and standard chargers, it is easy to cause abnormal charging, damage to chargers, and mobile terminals. [0003] At present, leaders in the mobile phone industry are all committed to researching that their mobile terminals can only use standard chargers. For example, mobile terminal products produced by Apple can only be charged with Apple chargers...
