In this embodiment, the threshold is set to be 0.1-0.25 times the volume of the battery, and the frequency of the ultrasonic wave is set to be 19-21 KHz. A large number of experiments prove that when the value range of the set threshold is selected to be 0.1-0.25 times of the volume of the battery, and the value range of the frequency of the ultrasonic wave is 19-21KHz, the accuracy of alarming to a user can be further improved, and the safety risk born by the user is reduced.
In this embodiment, the danger alert is an alert implemented by an electronic device in a graphic, video or audio manner. The pictures and texts can be matched through striking patterns and characters, such as red patterns of battery explosion and flame and character reminding of immediate power failure and remote. The video may be a dynamic presentation of the pattern. The sound can be the sound of dazzling and then the voice reminding is added to power off and keep away. Compared with the reminding mode of pictures, texts and videos, the sound reminding has the advantage that the transmission range is not influenced by the visual field condition, and the reminding is preferably implemented in a sound mode.
The invention also relates to a method for monitoring air bubbles in a battery of an electronic device, comprising the steps of sending S1, receiving S2, judging S4 and responding S5. Wherein the transmitting step S1 is to transmit ultrasonic waves to the battery of the electronic device.
