Embodiment Construction

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the implementation manners in the present invention, all other implementation manners obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0024] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. When an element is referred to as being "disposed on" another element, it ca...

Abstract

The invention provides an electronic device including a casing and a fan unit fixed on the casing. The electronic device further includes a monitoring component, and the monitoring component is arranged on the casing and used for monitoring the resonance frequency of the casing; and when the rotation frequency of the fan unit is the same as the resonance frequency of the casing, the rotation speedof the fan unit is adjusted to avoid the resonance frequency of the casing. The invention also provides a method for avoiding resonance, and the method is applied to the electronic device. Accordingto the electronic device and the method for avoiding resonance, the monitoring component and the fan unit are combined, and the rotation speed of the fan unit is adjusted to enable the fan unit to avoid the resonance frequency.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an electronic device capable of avoiding resonance between a fan and a casing, and a method for avoiding resonance. Background technique [0002] With the rapid development of heat dissipation technology, fan units are widely used in electronic devices, such as computers, to dissipate heat from the electronic devices. For example, when the operating frequency of a computer device is increased according to performance requirements, the internal temperature of the computer device will increase accordingly. Therefore, in order not to allow the internal temperature of the computer device to affect its operation, or even cause damage to the computer device, The fan unit is used to regulate the internal temperature of the computer device. [0003] However, when the electronic device is in operation, the amount of vibration generated by the rotation of the fan is transmitted to the...
