New description: [New technology field] This creation department has a kind of keyboard, especially a touch keyboard structure. [Prior Art] In recent years, touch panels and touch screens have been widely used as command input tools for electronic products such as mobile phones and computers. Taking a touch screen as an example, the user can conveniently touch the touch screen with his hand to input an instruction. In addition, taking the touchpad mounted on the keyboard as an example, the maker can touch the touchpad or slide on the upper side to issue an operation command to the computer in a mouse-like manner. Touchpads and touchscreens are usually available in resistive, capacitive, ultrasonic, and infrared types. Among them, resistive touchpads are the most popular. The design of resistive touchpads can be divided into four. Line, five-wire, eight-wire. The four-wire touch panel is the most basic production specification for all touch panel manufacturers because of its cost and technical maturity. Its basic structure is Indium Tin Oxide Glass (ITO Glass). , a conductive film (ITOFilm), in general, iT〇Giass and conduction use +5V voltage, and a spacer between the two, the purpose is to support ITO Glass and ITO Film Separate to avoid a false touch caused by a short circuit caused by no contact when there is no touch. In general, the resistive touch panel is non-contact between the first sensing layer disposed on the upper substrate (including the first conductive layer) and the 3 second sensing layer disposed on the lower substrate (including the second conductive layer). In the suspended structure, when the user presses, the first sensing layer must be in contact with the second sensing layer, and a signal is generated to perform subsequent operations on the control unit. If the pressing force is too small, the first sensing layer and the first sensing layer are If the two sensing layers are not in contact, the signal cannot be sent to the control unit, causing no action to occur. 'There is no feedback signal to the speaker or the LED to generate the sound, the user may think that the touch If the panel has problems or is in poor contact, the user will have problems with the product, and the manufacturer will be vulnerable to goodwill. In view of this, the creator of this case, with many years of experience in the manufacture and design of computer keyboards, actively researched and improved, and after many physical sample production and testing, and then specifically improved the above shortcomings of the conventional keyboard, and finally completed the book. creation. [New content] Therefore, the purpose of the present invention is to solve the above problems, and provide an intermediate layer of a piezoresistive material or a piezoelectric material as a direct support for the first conductive layer and the second conductive layer, thereby issuing a pressing signal. There is no need to touch the feedback signal after pressing, in order to improve the performance of the touch keyboard. Therefore, in order to achieve the above purpose, the present invention proposes a touch keyboard structure, which comprises a lower substrate, which is made of a plastic material; a second conductive layer is stacked on the lower substrate; Disposed on the second conductive layer at intervals, each of the pressing structures has a sensing layer, a contact layer and a connecting layer, and the sensing layer is stacked on the second conductive layer, and the contact layer is stacked Placed on the sensing layer of M395206, the domain contact layer is made of a resistive material, and the T-connected layer is stacked on the contact layer; the first conductive layer is disposed on the pressing structures; An upper substrate is made of a plastic material and is stacked on the first conductive layer. Preferably, the touch keyboard structure further comprises a plurality of gap sub-systems respectively disposed on the second conductive layer of each of the residual pressure structures, each of the gap sub-systems being connected to the first conductive layer by a glue layer . Preferably, the sensing layer is electrically connected to a control unit, and the control unit is electrically connected to a speaker or a light emitting diode.

The connecting layer 43 is laminated on the contact layer 42. Since the contact layer 42 is made of a piezoresistive material and has a piezoresistive effect, that is, when the sensing layer 42 is subjected to external pressure When it is on, its resistance value will change accordingly. Especially when the semiconductor material is used as the material of the domain measurement component, the resistance value changes to the material of the material. When the other is 224, the piezoelectric material is used. The characteristics of electrical materials are piezoelectric effect shirts (10) (10) (four) and belong to the county where the mechanical energy is exchanged with Wei, and the piezoelectric material will have the effect of electricity and electricity. Because of the 曰曰格(10) sub-pounds, the material has a stress field. The effect of coupling with an electric field, there are two kinds of piezoelectric effects, namely, positive piezoelectric effect (_cafe. fine effect) and back pressure effect (c〇nverse e In the case where the positive piezoelectric effect is based on mechanical energy, when the ferroelectric material is subjected to physical pressure, the electric dipole moment in the material will be shortened by compression, and this change will occur on the surface of the crucible. Charge (10) hides, that is, produces ^= or current signal, this _ is _ _ position; and the reaction is to convert electrical energy into mechanical. 'When an electric field (voltage) is applied to the surface of the piezoelectric material, the electric field acts M395206 k galvanic couple The pole moment is elongated. 'The piezoelectric material is elongated in the direction of the electric field to resist the change. The first conductive layer 5 is disposed on all the pressing structures 4, and the material of the upper substrate 6 is the same as that of the lower substrate 2, such as PET. A plastic material is formed and stacked on the first conductive layer 5. In addition, a printed layer (not shown) may be stacked on the upper substrate 6, and a number of _ button letter ships and numbers are printed.
