Detailed ways

The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

The elasticity of the buttons on the existing mobile terminals or mobile terminal models is fixed, which cannot meet the needs of different groups of people for the elasticity of the buttons. In order to solve the above problems, the present invention provides a button with adjustable elasticity.

As shown in Figures 1-3, the elastic adjustable button of the present invention includes a button mechanism 11, a dome 5, an adjustment mechanism 12 provided with a boss 121, an adjustment switch is arranged on the adjustment mechanism, and the adjustment structure The distance between the dome and the boss is adjusted by the adjusting switch, wherein,

The button mechanism includes a button 7, a decorative ring 6 and a button bracket plate 8 installed around the button, the button and the decorative ring are installed on one side of the button bracket plate, and the other side of the button bracket plate There are also silica gel sheets 4 respectively connected to the buttons and the decorative ring, and the silica gel sheets are contacted and connected to the domes.

Metal pins have specific and stable resilience (that is, automatic return after pressing), and have better hand feeling and longer life. They can also indirectly improve the production efficiency of various types of switches using conductive films. At the same time, they have ultra-long Long life, can bring high-quality tactile feedback to the operator. Metal pins are mainly used in membrane switches of rigid boards such as printed circuit boards. The working principle of the buttons of mobile terminals (including portable electronic devices such as mobile phones, iPads, notebooks, MP3s, etc., hereinafter taking mobile phones as an example) is that the button operator applies force to the buttons. PCB or FPC circuit board is connected to the conductive part, therefore, under the action of the force, the metal dome contacts the circuit on the PCB circuit board or FPC circuit board, thereby forming a loop, and the current passes through , the phone will work normally.

The button with adjustable elastic force of the present invention can be optionally applied to the mobile terminal model. Since there is no printed circuit board in the mobile terminal model, the button support plate can be optionally set as the first mobile phone shell during specific implementation.
