Problems solved by technology

But in many cases, due to the limited area of ​​the button area of ​​the mobile phone and the dense arrangement of the buttons, the sensing area of ​​each touch button is very close. When the finger is between two button areas, or the position of the finger is not so accurate, the resulting The induction cannot be guaranteed to be complet

Embodiment 1

[0020] As shown in Figure 3, a circular inner closed sensing area 23 is inlaid in the outer closed sensing area 13. When the finger presses the key marked with the number 9 on the keyboard, the inner and outer closed sensing areas 23, 13 are in contact with each other. For the keys marked with 6, 8, 0, #, only one closed sensing area or no closed sensing area is in contact with the finger, because the inner and outer closed sensing areas 23, 13 have to be sensed at the same time, the touch operation can be realized , so only the keys marked with the number 9 can be operated successfully, and the keys marked with 6, 8, 0, # will not be effective, which can effectively prevent the accidental touch of the keys, improve the accuracy of the touch keys, and bring convenience to the operator .

[0021] In this embodiment, the button panel is a plastic panel. The area size and shape of each key marked with the key logo on the key panel is consistent with the area size and shape of th...

Embodiment 2

[0024] Such as Figure 4 As shown, inlaid plum blossom sensor touch keyboard

[0025] For the convenience of portability, the size of the current laptop is getting smaller and smaller. Since the number of keys on the keyboard is not reduced, if it is used as a sensor key, the distance between each sensing area is too small, which is easy to cause false touches, and it is closed outside the chip. There is a quincunx-shaped inner closed sensing area 21 inlaid in the sensing area 11. Only when the finger touches the outer closed sensing area 11 and the inner closed sensing area 21 at the same time, and the two closed sensing areas 11 and 21 generate induction at the same time, the operation can be realized.

Embodiment 3

[0027] Such as Figure 5 As shown, the inlaid star-shaped induction area mobile phone button

[0028] The mobile phone keyboard itself is just small, so the false touch frequency of the sensing button is higher than that of the laptop. A star-shaped closed sensing area 22 is embedded in the outer closed sensing area 12, forming two closed sensing areas 22, 12 inside and outside. The finger touches the outer closed sensing area 12 and the inner closed sensing area 22 at the same time, and the operation can only be realized when the two closed sensing areas 12 and 22 generate induction at the same time.

[0029] Since a closed internal sensing area is set in the closed external sensing area, when the finger touches the key, the two closed sensing areas inside and outside need to be simultaneously sensed to operate. The advantage of this technical solution is that it not only prevents false touches caused when fingers are placed between the two sensing areas, but also avoids sim...

Abstract

The invention relates to an inlay type inductive touching key-press. An induced circuit board provided with a sensor and a chip is arranged under a key-press panel, and no less than one closed induction zones is arrayed on the sensor. The inlay type inductive touching key-press is characterized in that another closed induction zone is embedded in each closed induction zone on the sensor, and the two closed induction zones form an internal closed induction zone and an external closed induction zone; and an isolation area is arranged between the internal closed induction zone and the external closed induction zone. The size and the shape of each key-press area marked by a key-press marker on the key-press panel accord with the zone size and the shape of the corresponding external closed induction zone respectively. Another internal closed induction zone is also arranged in the external closed induction zone, so the operation can be carried out by inducting the internal closed induction zone and the external closed induction zone at the same time when a finger touches the key-press, the key-press is prevented from faulty touch effectively, the accuracy of the touching key-press is increased, and conveniences are brought to an operator.

Description

technical field [0001] The invention relates to a touch key, in particular to an inlaid inductive touch key. Background technique [0002] Touch sensing technology is an emerging technology, which has been widely used in electronic products in recent years, such as computers and mobile phones, and is mostly used as touch buttons. This technology uses the principle of capacitive sensing. There is a capacitance between two adjacent copper pours on the circuit board. When a finger (or other conductor) touches or approaches, a new capacitance is generated between the finger and the two copper pours. When Connect one of the copper pours to the analog I / O and the other to the ground, and you can judge the presence of a finger by measuring the change in capacitance, that is, to detect whether a button is pressed. Moreover, no matter what kind of dielectric (glass, plastic, stone, ceramic or wood) is placed between the sensing electrode and the human finger, the area signal can be ...
