Description of the Invention: [Technical Field] The present invention provides a hand-held device, and more particularly to a hand-held device using a speaker as an antenna. v [Prior Art] In recent years, with the needs of consumers and the advancement of modern technology, most of the electric φ sub-handheld devices have become more and more lightweight, and the functions have become more and more powerful, such as notebook computers, personal data. Assistants (Personal Data Assistant, pDA), mobile phones and global positioning systems, in addition to having powerful functions, small and lightweight are also features of these handheld devices. In the conventional handheld device, the Bluetooth device or the global positioning system has an antenna that is not designed on the printed circuit board or is additionally mounted on the handheld device. However, printed circuit boards in handheld devices have not only been soldered to various wafers and connectors, but printed circuits have also been densely distributed on printed circuit boards. If the printed circuit board is to be coupled with the antenna of the Bluetooth or global clamping system, it will inevitably cause difficulties in circuit design. If an additional Bluetooth or GPS antenna is installed on the handheld device, it will also affect the space arrangement in the handheld device, and even increase the size of the handheld device. Please refer to the 1st, 1st, which is a schematic diagram of the prior art speaker 100. The speaker 100 includes a film 102, a coil 104 attached to the film 1〇2, a holder 106, a permanent magnet 1〇8, and a conductor (e.g., a metal case) 11〇. When the coil 104 of the speaker 1281340 100 is energized, the interaction of the coil 1〇4 and the current generates a magnetic field, and the direction of the magnetic field changes due to the change in the direction of the current. The permanent magnet 108 under the film 1 也 2 also has a magnetic field, and the direction of its magnetic field does not change. When the current direction on the W coil 1〇4 is changed, that is, the magnetic field of the coil is changed, the magnetic field of the permanent magnet 108 and the magnetic field of the coil 104 are the same or opposite to the direction of the magnetic field, resulting in a force of attraction or repulsive. This attraction or repulsive force causes the coil 104 to move up and down, and in turn causes the film to vibrate up and down, thereby making a sound. The current direction on the coil 104 is controlled by a sound circuit or a sound amplifier that is lightly coupled to the coil 1 () 4. Additionally, conductor 110 can be used to protect internal components of speaker 100, such as film 1G2. An opening 112 may also be provided in the conductor (10) to allow sound generated by the film 102 to pass. In the prior art, the speaker and the antenna system are respectively located at different positions in the hand county, so the space in the handheld device is very wasted. SUMMARY OF THE INVENTION Accordingly, it is a primary object of the present invention to provide a hand-held device that is turned over. The ear 忭 天 天 天 发 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县The time of the Qualcomm and the high frequency signal processing module. In the case of 1281340, the other hand-in-hand includes a shoe, which has a conductor and a coil. The speaker further includes an audio amplifier coupled to the line, and the high frequency signal processing module is coupled to the conductor. [Embodiment] Please refer to Fig. 2 (and refer to Fig. 1 at the same time). Fig. 2 is a schematic view showing the use of the coil of the speaker (10) of Fig. 1 as the antenna. The handheld device 200 can be a radio handset, and the handheld device 2 includes a speaker with a coil (7) 4, a 100' high-pass filter 202 coupled to the coil 1〇4, and a low-pass filter 204 coupled to the coil 104. A high frequency signal processing module 2〇6 is coupled to the high pass filter 202, an audio amplifier 208 is coupled to the low pass filter 2〇4, and a matching circuit 210 |禺a the south pass filter is 202 and the south frequency signal is processed. Between modules 2〇6. As shown in Fig. 2, the coil 1〇4 of the speaker 100 is coupled to an audio processing terminal, that is, the audio amplifier 208, and a radio terminal, that is, the high frequency signal processing module 2〇6. The main function of the sound effect amplifier 208 is to amplify the sound signal to be emitted by the hand-held device 200 so that the power of the sound signal is sufficient to drive the coil 1〇4 of the speaker 1 and thus emit an appropriate sound size. The main function of the high frequency signal processing module 206 is to process the wireless signal. Therefore, the coil 1〇4 of the speaker 1 of the present invention can be used as an antenna to transmit or receive a radio signal in addition to the sound of the speaker 100. For example, when the sound amplifier 208 transmits an audio signal to the coil 104 of the speaker 1, the coil 1〇4 of the speaker 1 is used for sound generation, and the sound signal drives the coil 104 to make the speaker 1〇〇. The film 1〇2 vibrates and makes a sound. And 1281340, when the high-frequency signal processing module 206 is to transmit or receive a radio signal, such as a monitor signal or a global positioning system signal, the coil 1〇4 of the speaker 1 can be regarded as an antenna and used for transmitting Or receive high frequency signals such as radio signals. In addition, since the coil 104 of the speaker 100 is simultaneously coupled to the sound amplifier 208 and the south frequency signal processing module 206', the sound signal and the radio signal are bound to be mixed with the coil 104 of the speaker 100 and the circuit connected to the coil 1〇4, thereby causing Signal interference. For example, if the audio signal is transmitted to the radio, the radio communication may be disturbed, or if the radio signal is transmitted to the audio processing terminal, the audio signal may be mixed with radio noise. In order to prevent mutual interference between the audio signal and the radio signal, a high pass filter 202 is coupled between the high frequency signal processing module 206 and the coil 104, and a low pass filter 204 is coupled between the sound amplifier 208 and the coil 104. . The main function of the high-pass filter 202 is to filter a signal passing through the high-pass filter 202, allowing only the high-frequency portion of the signal to pass. Since the frequency of the radio signal is usually much higher than the frequency of the audio signal, an appropriate high-pass filtering is performed. The device 202 is coupled between the high frequency signal processing module 206 and the coil 1〇4 to filter out the lower frequency audio signal so that the audio signal does not interfere with the radio communication. On the other hand, the main function of the low pass filter 204 is to filter a signal passing through the low pass filter 204, allowing only the low frequency portion of the signal to pass, since the frequency of the audio signal is usually much lower than the frequency of the radio signal, A suitable low pass filter 204 coupled between the amplifier 208 and the coil 1 〇 4 can filter out higher frequency radio signals so that the radio signals do not interfere with the audio signal. 1281340 For example, when the sound amplifier 208 transmits an audio signal to the coil 104 of the speaker loo, the audio signal is first transmitted to the coil 104 through the low pass filter 204, and the coil 104 is also coupled to the high frequency signal processing module 206. Therefore, the audio signal is also transmitted to the high-frequency signal processing module 206. However, the audio signal passes through the high-pass filter 202 before reaching the high-frequency signal processing module 206, so the low-frequency sound signal is filtered by the high-pass filter. 202 is filtered out and cannot be transmitted to the high frequency signal processing module 206 'interfering with the radio communication. On the other hand, when the high frequency signal processing module 206 transmits or receives a radio signal through the coil 104 of the speaker 100, since the coil 104 is also coupled to the audio amplifier 208, the radio signal is also transmitted in the direction of the sound amplifier 208. However, the radio signal passes through the low pass filter 204 before reaching the effect amplifier 208, so the high frequency radio signal is filtered by the low pass filter 204 and cannot be transmitted to the audio amplifier 2〇8, which interferes with the sound signal. In summary, the high-pass filter 2〇2 and the low-pass filter 204 of the present invention are separated; the sound signal and the radio signal are taken into consideration, so that the two signals do not interfere with each other on the radio terminal and the sound processing end, thereby affecting the handheld Functional representation of device 2 请 Please refer to FIG. 3 (and refer to FIG. 3 at the same time), and FIG. 3 is another handheld device 300 of the present invention using the conductor 11 of the speaker 1 of FIG. 1 (H乍 is an antenna) The audio amplifier 3〇8 of the handheld device 300 is engaged with the coil, the high-frequency signal processing core group 306 is consumable to the conductor 11〇, and the matching circuit 31 is the turn-by-turn guide (four) and the high-frequency signal processing mode. Between group 304. As shown in Fig. 3, the speaker 〇4 of the speaker 1 is lightly coupled to the audio processing end, that is, the audio amplifier, and the conductor 1281340 110 of the speaker is coupled to a radio terminal, that is, The high frequency signal processing module 306. Thus, in addition to the speaker 100, the conductor 110 of the speaker 100 can be used as an antenna to transmit or receive radio signals. For example, when the speaker 1 is used as a sound. time cost The sound signal is amplified by the sound amplifier 308 and transmitted to the coil 104 of the speaker 100, and the sound signal drives the coil 104 to vibrate and emit the sound of the film 102 of the speaker 100. When the speaker 1 is used as an antenna, high frequency signal processing The module 306 uses the conductor 110 of the speaker 1 to transmit or receive a radio signal, such as a Bluetooth signal or a global positioning system signal, etc. In addition, although the speaker 1 is simultaneously coupled to the audio amplifier 3〇8 and The high frequency signal processing module 306, but the conductor 110 and the coil 104 in the speaker 1 are not connected, and the bracket 106 and the film 1〇2 between the conductor 110 and the coil 1〇4 are made of an insulating material. The composition is not electrically conductive, so the audio signal in the coil 1〇4 and the radio signal of the conductor 110 are not mixed in the speaker 100, thus causing a problem of signal interference. In other words, the handheld device 200, 3 of the present invention 〇0 No need to design the Bluetooth device or the full, positioning pure antenna on its printed circuit board, nor install a Bluetooth device or a full-bit system. The antenna is on the handheld device 2 (8), because the handheld device 200, 300 can utilize its existing speaker 100 to face the coil 104 or conductor no of the speaker 100 to a radio terminal, that is, the high frequency signal processing module lion, 306 To transmit or receive a radio signal, use the speaker coil (10) or conductor 110 as the antenna of the Bluetooth device or the global positioning system. 1281340 Please also refer to Figure 4 and Figure 5, Figure 4 is the second figure. A schematic diagram of the matching circuit 210 and the still-frequency signal processing module 206 of the device 200, and FIG. 5 is a schematic diagram of the matching circuit 31〇 and the high-frequency signal processing module 3〇6 of the handheld device 300 of FIG. The matching circuit 21 of the handheld device 200 is coupled between the high-pass filter 2〇2 and the high-frequency signal processing module 206, and the matching circuit 31 of the handheld device 3 is connected to the south and south frequency signals. Between modules 306. The main function of the matching circuit 21〇, 310 is for matching the antenna impedance. In the embodiment of the present invention, the matching circuit 210 (310) includes two capacitors 420 (52 〇), and the two capacitors 42 〇 (52 〇) may be used as the antenna impedance S& The DC part of the possession. However, the matching circuits 21G, 31() of the present invention are not arranged as shown in the figure. In other embodiments, the matching circuits 21, 31 can appropriately utilize the resistors and the electric valleys according to different situations. Electronic components such as inductors are combined in parallel, series, or parallel with a series connection. In view of the above, the present invention provides a hand-held device that utilizes a coil of a speaker 1 or a conductor 11G as an antenna, and the Tencel can be used as an antenna for the hand-held device 2GG, the middle bud or the global positioning system. Compared with the prior art, the handheld device of the present invention is fine, and the coil 1〇4 or the conductor 11〇 in the speaker 1〇〇 is effectively utilized as the antenna of the Bluetooth or global positioning system, and the saving county 200 is saved. The towel needs to be smashed into the ball (4). The work of the antenna can even further reduce the volume of the handheld device. 11 1281340 [Simple description of the diagram] Figure 1 is a schematic diagram of a prior art speaker.
