Portable electronic device

Abstract

A portable electronic device includes a housing, a first magnetic module, and a detachable input device. The housing has an upper surface and a receiving groove, the receiving groove being recessed from the upper surface. The first magnetic module is disposed within the housing. The detachable input device is detachably mounted in or detached from the receiving groove, and the detachable input device has a second magnetic module. When the detachable input device is mounted in the receiving groove, the portable electronic device provides an activation signal to the detachable input device, thereby activating the second magnetic module and generating a magnetic attraction between it and the first magnetic module to secure the detachable input device in the receiving groove.

5. The portable electronic device as claimed in claim 1, wherein each of the first to fourth tactile modules has a tactile pressure sensor configured to sense a force exerted by an external object on the detachable input device.

6. The portable electronic device as claimed in claim 5, wherein each of the first to fourth tactile modules further comprises an insulating element disposed between the corresponding tactile pressure sensor and the magnetic element, wherein the insulating element is made of a non-magnetic material.

7. The portable electronic device as claimed in claim 6, wherein each of the first to fourth tactile modules further comprises a transmission element connected between the corresponding tactile pressure sensor and the magnetic element.

8. The portable electronic device as claimed in claim 7, wherein each of the first to the fourth tactile modules further comprises a positioning element fixedly disposed on a corresponding tactile pressure sensor, the transmission element having a columnar structure, and the positioning element being configured to position the transmission element.

9. The portable electronic device as claimed in claim 8, wherein the detachable input device further comprises a first vibrator, each of the first tactile module to the fourth tactile module further comprises a second vibrator, and the vibration generated by the second vibrator is superimposed on the vibration generated by the first vibrator.

10. The portable electronic device as claimed in claim 9, wherein the detachable input device further includes a touch module, and when the first tactile module to the fourth tactile module senses that an external object applies force to the touch module and moves from a first force application position to a second force application position and finally stops at a third force application position, the first control circuit receives a sensing signal from the first tactile module to the fourth tactile module and outputs a sensing result to the second control circuit accordingly.

11. The portable electronic device as claimed in claim 10, wherein the second control circuit is configured to compare the sensing result with a lookup table to obtain a comparison result, and the first control circuit outputs a vibration signal to the second vibrator of at least one of the first to fourth tactile modules before the external object reaches the third force application position based on the comparison result.

12. The portable electronic device as claimed in claim 11, wherein the position of the second vibrator receiving the vibration signal corresponds to the third force application position.

13. The portable electronic device as claimed in claim 9, wherein an application executed by the portable electronic device is configured to output a prompt signal to the first control circuit, and the first control circuit outputs at least one vibration signal to the second vibrator of at least one of the first tactile module to the fourth tactile module according to the prompt signal, so as to cause the second vibrator to vibrate.

14. The portable electronic device as claimed in claim 1, wherein the detachable input device has a top surface and a bottom surface opposite to the bottom surface, wherein the top surface is provided with a touch module and the bottom surface is provided with a button module.

15.
