^ ^ Creative Department provides a keyboard module, especially a keyboard module used in portable, sub-devices, with detachable and light-emitting functions. [Previous technology] Press' With the development of electronic technology, the use of keys has increased greatly. In addition to the keyboard used by electronic devices, portable electronic devices such as mobile phones or personal digital assistants (PDAs) are equipped with keys. For use, and because the size of portable electronic devices is getting smaller and smaller, and the functional requirements are getting stronger and stronger, the buttons used on them must have the characteristics of lightness, thinness, and shortness, in order to meet different requirements. According to the needs of the user, by pressing the keys on the portable electronic device, the portable electronic device can make the portable electronic device accept the function of the digital corresponding signal pressed by the user 5. Therefore, the keys are very important for the portable electric device. 2. A conventional portable electronic device, such as a mobile phone, generally covers the body with a front case and two bottom cases. The front case is provided with a transparent window and most keyholes, and the body has a liquid opposite the window. The module, =, is provided with a keyboard opposite to the keyholes, the two disks have keys that protrude to the majority of the keyholes, and the bottom surface of the keyboard is provided with a gold 2 spring sheet and a keyboard rubber seat When a certain key is pressed, the rubber seat of the compass will be pushed down together, so that the rubber seat of the keyboard will be pressed against the keyboard control inside the mobile phone. In mobile phones, some mobile phone casings are replaced, and cannot be replaced. And the keyboard is limited to the front and the front shell can be made more than ten pairs of windows or the area of the keyboard, so that each
