Embodiment 1

[0036] For the analysis of the causes of the problems in the prior art, this embodiment cancels the connecting wire between the signal output point and the capacitive signal transmitting board, and directly sets the contacts on the circuit board (capacitive signal transmitting).

[0037] Such as figure 1 As shown, the capacitive touch screen operating handle circuit part of this embodiment includes sequentially connected operation keys ("key one" in the figure), a controller, a digital-to-analog conversion circuit, a signal generation circuit, a high-frequency signal generation circuit, and a high-frequency signal output The circuit, the transmitting end, the contacts, the battery and the boost circuit for powering the circuit, the charging interface of the battery charging circuit and the battery protection circuit.

[0038] figure 2 Is the circuit schematic diagram of this embodiment. Among them, the digital-to-analog conversion and signal generation circuit correspond to...

Embodiment 2

[0052] In order to further increase operational stability and reduce sluggish response, this embodiment proposes a double-contact technical solution, that is, the transmitting end includes two contacts: an output signal and a recovery signal, such as Figure 6A , 6B As shown, increase the signal recognition and recycling circuit and its contacts (contact four in the figure).

[0053] The circuit between the screen and the subsequent circuit is formed through contact four and its subsequent circuit, so as to recover the stray current formed by contact three, so that the sensing area formed at the contact point of the transmitter can prevent the output signal from remaining on the screen Form interference, so as to avoid the touch control failure caused by interference to the screen; on the other hand, the recovered circuit can be sent to the main controller for identification and judgment, so that it can be identified whether the signal emission of contact three meets the requi...

Embodiment 3

[0055] Such as Figure 7A , 7B As shown, on the basis of the double-contact scheme, this embodiment is changed to double-sided double-contact (a total of four contacts, divided into two groups, one group on one side), and the contacts 1 and 2 in the figure are added. ; Correspondingly, a button one is added to the button. In this way, the present embodiment has two transmitters and two buttons, which can be operated respectively corresponding to the left hand and the right hand of the human hand. This allows for a more two-handed fit. Since the player can usually set the button position on the game, although the relative positions of the two transmitters in this embodiment are fixed, it will not affect the use in practice.

[0056] Another advantage of setting the two transmitters on the same circuit board is that the contact distance between the two transmitters can be controlled, especially we can shorten the contact distance compared with the prior art. In the existing ...

Abstract

The invention provides a capacitive touch screen operating handle which comprises an operating key, a controller, a digital-to-analog conversion and signal generation circuit, a transmitting end and acontact which are electrically connected in sequence, the digital-to-analog conversion and signal generation circuit, the transmitting end and the contact are arranged on an induction main board, theinduction main board is arranged in a rotary chuck. The contact is exposed out of the rotary chuck, when the rotary chuck clamps the capacitive touch screen of the controlled equipment, the contact can be directly or indirectly contacted with the screen of the controlled equipment, and when the operation key is pressed down, a virtual touch signal can be generated on the contact to simulate the touch action of a person. Since the contacts are arranged on the circuit board, and a transmission line of a touch signal is canceled, the cost is saved, the production difficulty is reduced, and the signal transmission from the circuit board to the contacts is saved, and the signal attenuation is eliminated, so that the signal is more stable and reliable, and the phenomena of failure and slow response are reduced; and the width of a single contact can be smaller than that of the prior art.

Description

technical field [0001] The invention relates to a capacitive touch screen operating handle. Background technique [0002] With the popularity of smart devices, people spend more and more time operating capacitive touch screen touch screen devices in a day. Especially now that mobile phone games are popular, there are many virtual buttons to operate on the game, and players need to perform fast and accurate touch screen operations constantly, which is very inconvenient to operate. [0003] In the prior art, there are keyboard input, mouse input, and joystick input, etc., as methods for operating instead of manual touch screens. For mobile terminals such as smart phones or tablet computers, the operation mode of using the handle input has certain advantages, especially for game operations, the input through the handle can reduce the operation difficulty of the game and improve the playability. [0004] At present, the handle input mostly adopts the passive capacitive touch s...
