VI. Description of the invention: [Technical field to which the invention pertains] The present invention relates to a portable device, and particularly to a portable electronic device that activates a system by a magnetic induction method. [Prior Art] The slider structure is widely used in mobile phones, pDA (p_ai D (four) d ___ portable electronic device in a slide-to-view electronic device - generally has a body and a relative to the riding body. The different types of materials are used for the ride, and the portable electronic device can be used in the mode of the i-to-five (five). Generally, the cover body of the slide type portable electronic device realizes different functions. Generally, the magnetic induction method is used to change the shape of the portable electronic device, that is, the body and the cover body in the electronic device are connected to each other - the magnetic induction device and the corresponding magnetic device. When the cover body moves relative to the body, the magnetic induction device and the magnetic device are relatively moved. By sensing the position change of the magnetic device relative to the magnetic induction device, different functional circuits can be respectively turned on, thereby correspondingly starting different operations. In the mold mode, most of the methods require an additional magnetic device in the electronic device, which will increase the weight and volume of the portable electronic device, and lead to more cost-effectiveness. In view of the above, it is necessary to provide a portable electronic device that can save cost and has a small weight. A portable electronic device includes a body, a cover that is connected to the body and relatively moved. a magnetic induction unit, a signal processing unit and an audio output unit for outputting an audio signal. The magnetic induction unit is disposed in one of the body and the cover body, and the 201107933 2 frequency output unit 7 is disposed on the body and the cover body 2 The other is the audio output unit, and the audio output unit includes two miscellaneous readings. The sub-components of the hetero-components are embossed, and the sensing unit senses the magnetic elements and generates the sensing signals. The test signal 'Wei Lin Yuan Yuan Na _ job division job is different from this circuit' ^ makes the portable electronic device split (4) read mode. ~ 1 mesh compared to 1 know technology, this (4) portable electronic device use Its own audio output = set = part, double the cover used when switching the working mode =:;:==rr: When moving, the position of the _testing 7^ can be sensed The position of the body relative to the body changes, this can be used Wei circuit, the city's portable electronic device system's mode of operation. Thus, the portable f-sub-device does not need to add a magnetic device dedicated to the body to sense the relative position of the cover body and the body. The utility model can help reduce the volume and weight of the portable electronic device and reduce the cost. [Embodiment] Referring to FIG. 1 and FIG. 2, a preferred embodiment of the present invention provides a system for starting a system by magnetic proximity sensing. The portable electronic device of the portable electronic device can be a PDA with a mechanism, a flip structure, etc. The preferred embodiment is described by taking a mobile phone with a sliding structure as an example. The portable electronic device 100 includes a body 2 and a cover 4 slidably coupled to the body 20. Referring to FIG. 3 together, the body 2 includes a circuit board π and a solid The magnetic circuit element 24, a signal conversion unit 26 and a signal processing unit 27 are disposed on the f-way board 22 and electrically connected in sequence. The circuit board 22 can be a conventional printed circuit board (PCB) that is fixed in the body 20 and electrically connected by the circuit board. 201107933 . The magnetic induction unit % can be a conventional magnetic sensor that senses the change of the external magnetic field strength and outputs a sensing signal. The signal conversion unit 26 can be a conventional analog/digital converter (A/D Converter), which samples the sensed T number converted to the new number output by the magnetic induction unit 24, and outputs the scale to the signal processing unit 27. The signal processing unit 27 can be integrated with a central processing unit (Cemral plus (10) one-axis, cpu), and the signal processing unit 27 is used to control system actions such as starting the screen, starting the standby, and starting the screen to activate the screen protection mode. The cover body 40 includes an audio output unit 44 and a display soap θο 46 embedded in the cover body 4. The display unit 46 is electrically connected to the signal processing unit 27 described above. The audio output unit 44 is integrated with the conventional speaker of the portable electronic device 1 , and can be fixed in the cover 40 by means of a spring or the like, and its fixed position is opposite to the force sensing unit 24 . correspond. The audio output unit Μ is for outputting an audio signal, and has a magnetic element 442 and a coil (not shown). The magnetic element 442 can be a magnetic ring such as a ring/magnet. When the coil has an electric current, the coil interacts with the magnetic field of the magnetic element material 2 to generate an audio signal. When the cover body 4 is smashed relative to the body 2, the magnetic element 442 is moved relative to the body 2 〇 in a direction away from/near the magnetic induction unit ,, and the magnetic force of the magnetic induction unit 24 and the audio output unit 44 The magnetic field strength between the components changes. Then the magnetic induction unit 24 senses that the position of the sexual component changes and turns on the corresponding functional circuit. 〇isplay M〇dule lcm) is integrated, and its splicing and carrying type is called the unique working mode and correspondingly displays the output information. For example, when the cover body 4G is struck by the body 2G, the ', ', and the member's unevenness 70 46 is activated; when the cover body 4 is closed relative to the body 2, the display unit is turned off, the display unit 46 is activated, and the protection mode is stopped. Call status, etc. 201107933 • Please—and refer to 1 and FIG. 2 'When the cover 4G is opened/closed, the cover 40 phase is displaced to the body 20'. The magnetic element 442 of the audio output unit 44 itself is opposite to the magnetic induction unit 24 When moving, the magnetic field strength between the magnetic induction unit 24 and the audio output unit is changed; the magnetic induction unit 24 senses the output of the magnetic field of the magnetic field - the signal to the signal exchange unit %, the signal The conversion unit 26 converts the sensing signal into a digital signal and outputs it to the signal processing unit ^. The signal processing unit 27 is configured to select different working modes of the portable electronic device, such as starting/closing the display unit 46, starting the display unit 46 to protect the mode, stopping the call state, and the like. π can understand that the magnetic domain unit 24 can be disposed in the cover 4 (), the audio output unit 44 is correspondingly disposed in the body 2 ,, as long as the relative displacement between the cover 4 〇 and the body 2 发生The relative position between the magnetic induction unit 24 and the audio output unit 44 may be changed. In the preferred embodiment of the portable electronic device of the present invention, the portable electronic device brain uses the magnetic component of the audio output unit 44 of its own, and also serves as the mode when the programmable electronic device 100 switches the working mode. The cover 40 is positioned to be a magnetic device. When the body 20 and the cover 40 are shackled, the body 2G can sense the cover 4 by the position of the magnetic element 442 in the single cymbal 44.位置 Changes in position relative to the body 2〇. In this way, different functional circuits can be switched on correspondingly, thereby switching the operating mode of the system. Therefore, the portable electronic relay needs to additionally add a magnetic device dedicated to the body 2 to sense the relative position of the cover 4 and the body to help reduce the portable electronic The size of the device is reduced and the cost is reduced. In the above, the present invention complies with the requirements of the invention patent and submits a patent application according to law.
