Embodiment Construction

[0058] As mentioned in the background section, the charging time of electronic devices in the prior art is getting longer and longer, which makes it difficult to meet people's demand for fast charging of electronic devices, and the user experience is poor.

[0059] In view of this, an embodiment of the present invention provides an electronic device, including: a battery, a piezoelectric induction structure, and a resonance structure. The resonance structure generates resonance under the action of ultrasonic waves. When the resonance structure vibrates, it gives the The piezoelectric induction structure exerts a force so that the piezoelectric induction structure generates a current to charge the battery, wherein the resonance structure has at least two resonance frequencies.

[0060] Correspondingly, the embodiment of the present invention also provides a charging method for an electronic device, which receives ultrasonic waves;

[0061] Under the action of the ultrasonic wav...

Abstract

The embodiment of the invention discloses an electronic device, a charging method thereof, and a ultrasonic wave generating device and method. The electronic device comprises a battery, a piezoelectric induction structure, and a resonant structure. The resonant structure generates resonance under the effect of a ultrasonic wave and applies acting force to the piezoelectric induction structure while vibrating in order that the current generated by the piezoelectric induction structure charges the battery. The resonant structure is provided with at least two resonant frequencies in order that the electronic device is provided with at least two charging currents. Thus, the electronic device can be rapidly charged by large charging current when the electric energy of battery is low. Therefore, the charging time of the electronic device is shortened; a requirement of people for rapidly charging the electronic device is satisfied; and user experience is improved. When the electric energy of battery is high (namely the battery is almost fully charged), the electronic device is charged by low charging current in order that damage of large charging current to the battery is reduced.

Description

technical field [0001] The invention relates to the technical field of charging electronic equipment, in particular to an electronic equipment and a charging method thereof, as well as an ultrasonic generating device and a generating method thereof. Background technique [0002] With the development of electronic technology, the display screens of electronic equipment become larger and more integrated with more and more functions, resulting in an increasing power consumption of the electronic equipment. In order to ensure a certain standby time for the electronic device, its battery capacity is correspondingly larger and larger, resulting in a longer and longer charging time for the electronic device, which is difficult to meet people's demand for fast charging of electronic devices. poor. Contents of the invention [0003] In order to solve the above technical problems, the embodiments of the present invention provide an electronic device and its charging method, and an ...
