Description

Button structure and mobile communication terminal applying the button structure

The invention relates to a button structure and a mobile communication terminal using the button structure, in particular to a button structure capable of vibrating a caller number and a mobile communication terminal applying the button structure.

With the development of wireless communication and information processing technology, mobile communication terminals have become an indispensable part of people's lives. At present, mobile communication services have generally joined the caller identification function of the caller. When the mobile communication terminal user receives an incoming call, the caller identity can be known before answering the call.

The incoming call prompt of the mobile communication terminal mainly uses LCD (Liquid Crystal Display), vibration and ringtone prompts. When the user is in a public place or is inconvenient to answer the call, the mobile communication terminal is usually set to a vibration mode, which prompts the call by vibration. However, this vibrating alert usually only serves to prompt the presence of an incoming call, and the identity of the caller, such as the caller number, the caller's name, etc., is not recognized. Users usually need to check the LCD to know the identity of the caller. For users with visual impairment, once the mobile communication terminal is tuned to the vibration mode, the caller information is not easy.

At the same time, the button structure for information input has become an important component of the mobile communication terminal, and the existing button structure is mostly designed only for its shape or structure, so that it has a good feel, or reduces its volume, etc., so the button structure The function is relatively simple, usually only used to input information, and has no other functions.

In view of this, it is necessary to provide a button structure that can vibrate the caller number.

In addition, it is necessary to provide a mobile communication terminal to which the button structure is applied.

A button structure includes a button cap, a button body and an elastic body. The button cap and the button body are sequentially disposed on the elastic body, and an accommodation space is formed between the button cap and the button body; the button structure further includes A vibrating body is disposed in the accommodating space, and when the vibrating body is turned on or off, the button cap is vibrated.

A mobile communication terminal includes a circuit board, a button panel and a plurality of button structures; the button structure comprises a button cap, a button body and an elastic body; the button cap and the button body are sequentially disposed on the elastic body; the elasticity The body is disposed on the circuit board, and the button body and the button body form an accommodating space; the button structure further includes a vibrating body, the vibrating body is disposed in the accommodating space, and the vibrating body is turned on or off. When the power is turned on, the button cap is vibrated.

Compared with the prior art, the button structure of the present invention can vibrate the caller number and break through the limitation of displaying the caller number only through the LCD.

The button structure of the preferred embodiment of the present invention is installed in a mobile communication terminal to vibrate the caller number when the mobile communication terminal calls.

Referring to FIG. 1 , a key structure 10 of a preferred embodiment of the present invention is installed in a mobile communication terminal (not shown). The mobile communication terminal includes a circuit board 21 and a button panel 22 . The button panel 22 includes an operation surface 221 and an opening 222 defined therein. The button structure 10 includes an elastic body 11 , a button body 12 , a button cap 13 and a vibrating body 14 . The button body 12 and the vibrating body 14 and the button cap 13 are sequentially disposed on the elastic body 11. The vibrating body 14 can move the button cap 13 relative to the button body 12 to form a vibrating state at the opening 222 of the operating surface 221 .

The elastic body 11 is made of an elastic material having an arcuate surface. The elastic body 11 can be disposed on the circuit board 21 built in the mobile communication terminal.

The button body 12 is a hollow body, and includes a base body 121, a pressing portion 122, a pressing portion 123 and a guiding post 124. The contact portion 122 and the pressing portion 123 are respectively extended from the central position of the base 121 in the opposite direction perpendicular to the base 121. The contact portion 122 is provided on the elastic body 11. The pressing portion 123 is a hollow cylindrical body including a first surface 1231 and a second surface 1232 opposite to the first surface 1231. The guide post 124 is made of a soft material which is a hollow columnar body. The guiding post 124 extends from the adjacent edge of the base 121 in a direction parallel to the contact portion 122, and the open end thereof is connected to the circuit board 21.

The button cap 13 is a hollow rectangular cover body including an inner surface 131 opposite to the first surface 1231 of the pressing portion 123. The button cap 13 is sleeved on the pressing portion 123 of the button body 12 and forms an accommodation space 15 with the first surface 1231 of the pressing portion 123 of the button body 12 .

The vibrating body 14 includes a metal member 141, an electromagnet 142, a resilient piece 143, and a wire 144. The metal member 141, the electromagnet 142, and the elastic piece 143 are accommodated in the accommodating space 15. The metal member 141 is fixed on the inner surface 131 of the button cap 13 , and the electromagnet 142 is fixed on the first surface 1231 of the button body 12 . The electromagnet 142 is located on the same vertical line as the center of the metal member 141. When the electromagnet 142 is not magnetic, that is, in a normal state, between the two When there is a proper distance; when the electromagnet 141 is magnetic, the metal member 141 is attracted to the metal member 141, and the distance between the two members is zero. The elastic piece 143 is a sheet body, and one end of the elastic piece 143 is fixed on the button body 12, and the other end is fixed to the metal piece 141. One end of the wire 144 is connected to the electromagnet 142, and the other end is led out from the second surface 1232 of the button body 12, and is connected to the circuit board 21 via the guiding post 124.

The wire 144 can be connected to a power source (not shown). The power source can be a power source on the circuit board 21 or an external power source. When the wire 144 is connected to the power source, the electromagnet 142 connected thereto will have magnetic force and attract the metal member 141, so that the metal member 141 drives the button cap 13 toward the button body 12; when the power is turned off, The magnet 142 disappears, the attraction between the metal member 141 and the electromagnet 142 disappears, and the metal member 141 moves away from the electromagnet 142 due to the elastic force of the elastic piece 143, and simultaneously drives the button cap 13 away from the button body 12, so The control power supply is turned on and off at a certain frequency, so that the button cap 13 of the button structure 10 is continuously approached or away from the button body 12, so that the button structure 10 forms a vibration state on the operation surface 221 of the mobile communication terminal. . When the mobile communication terminal calls, the button structure 10 vibrates one-to-one corresponding to the number corresponding to the caller number, thereby prompting the user to call the number.

The button structure 10 can vibrate to prompt the caller number, and break through the limitation of displaying the caller number only through the LCD.
