When the object is in the process of acceleration, such as shaking, falling, rising or falling, all kinds of movement changes are G- The Sensor is converted into an electrical signal, which is then calculated and analyzed by the microprocessor to perform the intended function. For example, Mp3 can change the song being played to the previous or next song according to the direction of the user's sway, or calculate the user's advancement when the MP3 is placed in the pocket. In addition, some high-end notebooks have a ^-sensor inside, and when they sense a sharp acceleration (such as accidentally falling down), they immediately protect the hard disk to avoid damage to the hard disk. This is because G-Sensor is a smart gravity sensing system that can detect the current state of the hard disk on the hard disk. When an accidental drop occurs, the hard disk senses the resulting increase, and the head is automatically reset. , the disc body and the magnetic head are separated 'to prevent the normal reading/writing of the data from accidental impact when the reading and writing operation is performed. On the other hand, the G-sens〇r technology can also be applied to mobile phones. When the user is waving the mobile phone, the application software that can be used in comparison with the fabric behavior is, for example, playing games, listening to Mp3 or taking photos, etc. ^ 1 201115446 WiFi microelectromechanical system (MEMS: 龃 (10) • EleftromechaniCal System), which is a micro-electromechanical system that integrates miniature sensors, actuators, and #唬 processing and control circuits, interface circuits, communications, and power. However, in the prior art, when the mobile phone with G_sens〇r is in motion, the function of the mobile phone is relatively simple—the user cannot pick up the phone freely, which reduces the user experience. Furthermore, there are currently few measures to protect handheld devices under water, and in the unlikely event that a user's handheld device falls into the water, it will cause significant damage. SUMMARY OF THE INVENTION The above-mentioned shortcomings of the prior art for electronic devices in sensing technology provide an embodiment for pressure triggering of electronic devices, which provides a resistive strain preparation.

More specifically, an adhesive can be used to secure the pressure sensor to the outer surface of the electronic device. In addition, a protective film can be placed on the pressure sensor. Preferably, the pressure sensor can be a strain gauge or a half conductor strain gauge. When the pressure sensor is a strain gauge, the resistance value of the strain gauge is proportional to the stress change of the electronic device. When stress

Preferably, when the external force applied to the electronic device changes, the resistance value of the pressure sensor also changes accordingly, and the electronic device can switch from one application function to another. According to still another embodiment of the present invention, an electronic device is provided, comprising: a housing, a pressure triggering device, and a control module. The 'pressure triggering device' includes a pressure sensor, a resistance strain wire and . Pressure sigh module. Wherein, one end of the resistance strain wire is connected to the pressure sensor, and the other end is connected to the outer casing of the electronic device. The pressure setting module is used to receive the resistance value change of the resistance strain wire and convert it into the corresponding pressure value.

According to still another embodiment of the present invention, a pressure triggering method for an electronic device is provided. In this pressure triggering method, the user first presses the pressure sensor of the electronic device and then uses the pressure sensor to obtain the corresponding pressure value.

[Embodiment] Hereinafter, a detailed description of a specific embodiment of the present invention will be made with reference to the accompanying drawings. First, let's briefly introduce the piezoresistive sensor and piezoresistive effect. A dust-resistance sensor is a device made of a diffusion resistance on a substrate of a conductor material according to a piezoresistive effect of a semiconductor material. Among them, the substrate can be directly used as a sensing element for measurement, and the diffusion resistor is in the form of a bridge in the substrate. When the substrate is not subjected to an external force, the bridge is in equilibrium state 'the output voltage is zero; when the substrate is deformed by an external force, the resistance values of the bridge t will change, so the bridge is balanced by the original 201115446. The state is converted to an unbalanced state 懕.

重里、應變、流量、真空度)的測量和控制,並且: 壓阻式感測器的基片材料主要切片或鍺片,I中又以 石夕片作為材料的固態壓阻式感測器應用最為普遍。那 麼’什麼是壓阻效應呢?以單晶石夕材料為例,當外力作 用於石夕晶體時,晶體的晶格產生形變,使載流子從一個 能谷向另-個能榖散射’引起載流子的遷移率發生變 化,從而擾動了載流子縱向和橫向的平均數量,從而使 矽的電阻率改變,通過測量電路就可以得到與外力變化 成正比的電信號輸出。 本領域的普通技術人員應當理解,載流子遷移率的 變化隨晶體取向的不同而不同,因此,矽的壓阻效應與 晶體的取向有關。此外,矽的壓阻效應不同于應變計(即 電阻應變δ十)’ 是因為’壓阻效應中的電壓變化主要 取決於石夕電阻率的變化’而電阻應變計中的電壓變化主 要取決於石夕材料本身幾何尺寸的變化,並且,壓阻效應 的靈敏度比應變計的靈敏度大50-100倍。由此可知, 在壓力觸發裝置中,採用壓阻式感測器可以獲得更高的 靈敏度。 在壓阻式應變感測器中,電阻應變絲是將被測件上 的應力變化轉換成為一種電信號的敏感器件。它是壓阻 式應變傳感器的主要組成部分之一。電阻應變絲應用最 201115446 多的疋金屬電阻應變絲和半導體應變絲兩種。金屬電阻 應變絲又有絲狀應變絲和金屬箔狀應變絲兩種。通常是 .將應變絲透過特殊的粘合劑緊密地粘合在產生力學應 變的基體上,當基體受力發生應力變化時,電阻應㈣ 也一起產生形變,使應變片的阻值發生改變,從而使加 在電阻上的電厘發生變化。這種應變片纟受力時產生的 阻值變化通常較小,-般這種應變片都組成應變電橋, 並透過後續的儀表放大器進行放大,再傳輸給處理電路 (通常是A/D轉換和CPU)顯示或執行機構。 其中,金屬電阻應變片的工作原理是吸附在基體材 料上的應變電阻隨機械形變而產生阻值變化的現象,俗 稱為電阻應變效應。金屬導體的電阻值可用下式表示:Measurement and control of gravity, strain, flow, vacuum), and: The substrate material of the piezoresistive sensor is mainly sliced or bracted, and the solid-state piezoresistive sensor application using Shi Xi tablets as material in I Most common. Then what is the piezoresistive effect? Taking a single crystal material as an example, when an external force acts on the crystal, the crystal lattice of the crystal is deformed, causing the carrier to change from one energy valley to another, causing the mobility of the carrier to change. Thus, the average number of longitudinal and lateral carriers is disturbed, so that the resistivity of the crucible is changed, and the electrical signal output proportional to the change of the external force can be obtained by the measuring circuit. It will be understood by one of ordinary skill in the art that the change in carrier mobility varies with crystal orientation, and therefore, the piezoresistive effect of germanium is related to the orientation of the crystal. In addition, the piezoresistive effect of tantalum is different from that of strain gauges (ie, resistive strain δ ten) because 'the voltage change in the piezoresistive effect depends mainly on the change of the resistivity of the stone' and the voltage change in the strain gauge mainly depends on The geometrical dimensions of the stone material itself vary, and the sensitivity of the piezoresistive effect is 50-100 times greater than the sensitivity of the strain gauge. It can be seen that in the pressure triggering device, a piezoresistive sensor can be used to obtain higher sensitivity. In a piezoresistive strain sensor, a resistive strain wire is a sensitive device that converts a change in stress on a device under test into an electrical signal. It is one of the main components of a piezoresistive strain sensor. The resistance strain wire is applied to the most 201115446 bismuth metal resistance strain wire and semiconductor strain wire. Metal resistance The strained wire has two kinds of filament strained wire and metal foil strained wire. Usually, the strained wire is tightly bonded to the mechanical strain-producing substrate through a special adhesive. When the stress is changed by the force of the substrate, the electrical resistance should be deformed together to change the resistance of the strain gauge. Thereby, the electric power applied to the resistor changes. The strain gauges usually have a small change in resistance when they are stressed. These strain gauges are all formed into strain bridges and amplified by subsequent instrumentation amplifiers and then transmitted to the processing circuit (usually A/D conversion). And CPU) display or actuator. Among them, the working principle of the metal resistance strain gauge is that the strain resistance adsorbed on the base material changes with the resistance of the mechanical deformation, which is commonly called the resistance strain effect. The resistance value of the metal conductor can be expressed by the following formula:

If the wire is subjected to an external force, the length will increase, and the cross-sectional area will decrease, and the resistance value will increase. Big. When the wire is compressed by an external force, the length is decreased and the cross-section is increased, and the value is decreased. Therefore, as long as the change in resistance value (usually the voltage across the resistance) is measured, the strained wire can be obtained. 201115446 FIG. 1 is a schematic diagram showing the structure of the schematic embodiment of the pressure triggering device of the present invention. Schematic diagram. In Fig. 1, a schematic structural view of a mobile handset having a pressure triggering device is described. One of ordinary skill in the art will appreciate that a mobile handset is just one of many devices that include a pressure triggering device, but the invention is not limited thereto. For example, it can also be a personal digital assistant (ρΜ), or a digital device that can be used for digital devices (such as digital devices compatible with gaming functions, music listening functions, or camera functions). •. As shown, the waste force triggering device includes at least: an outer ring pressure sensor 100, a body 102, and a resistance strain wire 104. The outer ring pressure sensor 100 can be a strain gauge or a semiconductor strain gauge. Here, the resistance strain gauge is exemplified, and the resistance strain gauge is tightly bonded to the body i (10) which generates the mechanical strain by a special adhesive, and is used to convert the force change of the mobile phone body 102 into an electric signal. When an external force is applied to cause a stress change in the body 102, the strain gauges j are deformed together, and the resistance value of the strain gauge is changed, so that the voltage applied to the resistor also changes. It will be understood by those skilled in the art that the resistance strain gauge has a relatively small change in resistance when the body is in force, and it is usually necessary to form the strain gauge into a strain bridge, which is amplified by a subsequent instrumentation amplifier and then transmitted to the processing circuit.

Figure 3 is a schematic diagram showing the function of the pressure triggering device in Figure i under different pressure values. In Fig. 3, it includes: 12 201115446 h Step 300, setting the pressure range, and performing subsequent processing when the pressure value corresponding to the resistance value is within the range. At this point, it is necessary to set a lockl to lock the application so that the lockl flag bit is loaded when the user needs to use the pressure trigger device, and the l〇ckl flag bit is released when the user does not need to use the pressure trigger device. In other words, the pressure triggering device can be used to set the pressure range as the l〇ckl layer; in step 302, the specific pressure value is transmitted, and steps 3〇4, 3〇6, and steps are performed according to the preset respective pressure ranges. 3〇8, step 310 or step 312. At the same time, a further flag bit is set to latch the various applications based on the pressure values, these applications are the start game of step 3〇4, the call to step 306, the play music of step 308, and other functions of step 310. And read the document in step 312. When the user wants to select to start the game, make a call, play music, read the text or other functions, the 1 ock 2 standard bit is loaded, and when the user does not need to select these applications, the l〇ck2 flag bit is released and returned to i〇 Ckl layer. In other words, the corresponding pressure change is only valid in the i〇ck2 layer, and the pressure value corresponds to any one of the steps 304, 306, 308, 310 or 312; step 304 'when the pressure value is 10-20, The mobile phone starts the game; Step 306 'When the pressure value is 〇-1〇, the mobile phone answers the call; Step 308, when the pressure value is 20-30, the mobile phone plays music; Step 312' When the pressure value is 30-40, the mobile phone Read the document, for example, can be 'but not limited to, w〇rd format or pdf format document; and 13 ES] 201115446 step 310, when the pressure value is in other intervals in the pressure range - when the phone performs other functions. For example, mobile phone standby, etc. In addition, when playing music or reading a document, the loaded 1 ock3 flag can also be used to set the track for music playback and the number of pages the document reads. Specifically, when step 3〇8 is performed, the mobile phone starts playing music, and the power change is used to set the play track in step 314. Also, when the pressure is 0-10, play the previous or next track; when the pressure is 10-20, turn the two tracks forward or backward to start broadcasting, and so on. When the lock3 layer needs to be exited, the i〇ck3 flag bit is released and returned to the l〇ck2 layer, where the pressure change is used to select each application in the lock2 layer. Similarly, when step 312 is performed, the phone reads the word or pdf document and the pressure change is used to set the page turning in step 316. Also, when the pressure is 〇_1〇, turn forward one page or backward, when the pressure is 10-20, turn two pages forward or backward, and so on. When the lock3 layer needs to be exited, the 1〇ck3 flag bit is released and returned to the lock2 layer, where the pressure change is used to select each application in the 1〇ck2 layer. It can be seen from step 314 and step 316 that after entering the 1〇ck3 layer, the transmitted pressure value range no longer selects each application in 1〇ck2, but is used to judge whether to forward or backward when playing music. The number of tracks' and the number of pages turned forward or backward when reading a document. That is to say, the application of the 1 ock3 layer includes two situations of setting a play track and setting a page turn. 201115446 The implementation of the pressure triggering device of the present invention is described in the following section. We describe the implementation flow of the pressure triggering method in combination with a detailed execution step.
