Abstract

The invention provides a keyboard cover and an electronic device with the keyboard cover. The electronic device comprises a shell and the keyboard sleeve, wherein the shell is detachably arranged on the keyboard sleeve, the keyboard sleeve comprises a body, at least one sensor, a keyboard and a driving circuit, the driving circuit is electrically connected with the keyboard and the sensor, when the sensor detects that the electronic device is placed on the keyboard sleeve, a driving signal is sent to the driving circuit, and the driving circuit starts the input function of the keyboard when receiving the driving signal. The electronic device is advantaged in that the input function of the keyboard is triggered through electric field induction between the sensor and the driving circuit, a sensor driving circuit does not need to be specially arranged, production cost is effectively reduced, and the service life of a product is prolonged.

Description

technical field [0001] The invention relates to a keyboard cover and an electronic device with the keyboard cover. Background technique [0002] With the development of science and technology, the application of smart electronic devices such as smart phones and tablet computers is becoming more and more extensive. Since the keyboard area of ​​the intelligent electronic device is small, it is not convenient for the user to operate, so many users choose an external keyboard. In the prior art, external keyboards usually use Hall sensors to trigger the input function through electromagnetic induction. This method requires additional detection circuits and magnets, which increases the components and weight of the keyboard and increases the product cost. Contents of the invention [0003] In view of this, it is necessary to provide a keyboard cover and an electronic device having the keyboard cover to solve the above technical problems. [0004] A keyboard cover, including a b...
