Description of the invention (1) Technical field (please read the precautions on the back before filling out this page) The present invention relates to an electronic circuit including a wristband, a casing, and a receiver for receiving radio broadcast signals The portable electronic device includes an antenna disposed in the wristband. More specifically, the present invention relates to a specific antenna structure that allows the portable device to receive signals whose frequency is in the extremely high frequency range (ie, V H F radio waves) under high sensitivity. The antenna is preferably capable of receiving signals belonging to the frequency modulation (Frequency Modulation; FM) frequency band. In other words, the frequency of the signal includes a range between 87 MHz and 110 MHz. Prior Art Such devices have been disclosed in the prior art and, in particular, various very different antenna structures have also been proposed. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs For example, we can refer to US Patent 4,7 54,285, which was granted a patent right on June 28, 1988. This patent discloses a watch, which is especially provided with a purpose To receive radio broadcast signals, and the watch needs an antenna. The disclosed solution is characterized by arranging a metal wire over the entire length of an extensible wristband, and continuously surrounding the metal wire along the width of the wristband. Therefore, the length of the metal wire is longer than the length of the wristband in the rest position, and then the wristband is extended. However, in addition to taking up a considerable amount of space in the wristband, this solution is not suitable for watches whose wristband contains two components and these two components are joined to each other via a snap-fit device. -5- This paper size applies to Chinese National Standard (CNS) A4 specification (210X 297 mm) 200301025 A7 B7 V. Description of invention (2) (Please read the notes on the back before filling this page) In order to respond to this specific In other cases, other solutions have been proposed, such as passing a simple metal wire loop through each of the two component parts of the wristband, and the metal wire loop is self-connected to the watch case. One end of a wristband component is provided to the other end of the wristband. A device for establishing an electrical connection between the two parts of the ring is also provided at the position of the fastening device. However, these connecting devices complicate the structure of the wristband, and the situation may be more serious, because it is best to protect these connecting devices from the external environment, especially the sweat of the user who wears the watch This means that considerable protective measures must be taken. SUMMARY OF THE INVENTION The consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs printed this case. The applicant has confirmed in his research that the portable electronic device described above can be improved due to the present invention, and this improvement is particularly attributed to a simple Antenna structure. Although this antenna structure is simple, it provides good VHF radio signal reception sensitivity. The solution according to the present invention can use such an antenna without requiring much modification to the structure of the prior art integrated into the present invention. The invention therefore relates to a portable electronic device of the type previously described, characterized in that the antenna comprises at least one flat coil made in the form of a spiral winding. Therefore, the space requirement of the antenna in the 'wristband' is extremely limited, while ensuring that the electronic device according to the present invention has the best reception quality. In the second embodiment, the antenna may include the shape of a spiral winding -6-This paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) 200301025 A7 B7 V. Description of the invention (3) (please First read the precautions on the back before filling out this page). This embodiment can further improve the sensitivity of the device according to the invention, as long as the two coils are connected in series, this embodiment only involves a very slight increase in the space requirement of the antenna in the wristband. We can imagine that, in order to implement the embodiment in a device including a wristband made of two independent parts, the first coil of one of the two coils is arranged in a first component, and The second coil is arranged on a second wristband component. We can also imagine that each coil is manufactured by depositing a copper path on a substrate, and in this case, a first coil is arranged on a first side of the substrate, and The second coil is disposed on the second surface of the substrate. This modification helps to make a connection device for an integrated circuit that leads to a radio broadcast signal receiving circuit, and is particularly helpful when the integrated circuit is installed in a housing of an electronic device. Of course, it is preferable that the base plate for supporting the antenna according to the present invention is made of a flexible material so that the wristband can be deformed. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs In general, because the integrated circuit of the receiving circuit is arranged in the casing of the electronic device, the integrated circuit is connected to one or more of these by a metal path The end of the coil. The metal paths are preferably supported by an extension of the base plate extending into the interior of the housing. In addition, since the coil has a specific spiral shape, an opening is arranged in the substrate so that the inner end of the coil is connected to the corresponding metal path. In a preferred embodiment, the solution described above is implemented in a timer. In this case, the case contains a timer mobile single paper. The dimensions are applicable to the Chinese National Standard (CNS) A4 specification ( 210X297 mm) · 7-200301025 A7 ___B7___ 5.

With the objective of optimizing the surface available in a wristband, the substrate (4) has a substantially rectangular shape. Similarly, the spiral winding of the coil (2) has a generally rectangular shape so that the available substrate surface Optimization. A particularly advantageous system is obtained because the surface of the coil (2) can be much larger than the surface in the case where the coil is installed in a portable device. A first end (5) is located outside the spiral, and extends the first end (5) by an extended rectangular connector (6) disposed on an extension (7) of the base plate (4), and the The extended rectangular connector (6) is used to connect the first end (5) of the coil (2) to an integrated circuit (as shown in FIG. 2).

This aspect of the operation of the portable electronic device (15) will not be described in detail herein because this aspect is only one of the major aspects of the present invention. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs will not further elaborate on the structural details related to the passage of the extension (7) of the substrate (4) carrying two rectangular connectors (6) and (8). This is because many solutions have been proposed in prior art documents. Interested readers may refer to, for example, European Patent Application 1 033 636 published on September 6, 2000, which is hereby incorporated by reference for reference. In fact, the description of this patent application shows several embodiments of the passage of the electronic connector of a watch in a waterproof manner. As a whole, the solution disclosed in this patent application is characterized in that an opening is arranged on the side of the watch case, and a channel (24) having a substantially tubular shape is arranged in the opening. A sealing device (2 5) is provided between the watch case (1 8) and the outside of the tubular passage (24). This channel guides these electrical connectors to ghai table-12- This paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) 200301025 A7 B7 V. Description of the invention (9) (Please read the first Note: Please fill out this page again) Inside the case 'and equipped with a device to ensure that the inside of the channel (24) is sealed from the outside of the case. These seals are made in the form of a joint (26), such as overmolded near the electrical connectors, and the joint (26) has the same shape as the interior of the channel, thus ensuring a plugging function. A device such as an electrical connector may not be provided such that it does not penetrate the interior of the electronic device housing itself. We can use a set of joint contacts such as described in European Patent Application 0 1 86 804, and we can even use a capacitive coupling obtained in the device enclosure described in European Patent Application 1 014 23 1. From a self-sealing point of view, the latter embodiment advantageously facilitates the construction of the housing (18) of the device, since this way does not require an opening to be made in the housing. Figure 3 shows a second embodiment of one of the antennas (1) of the portable electronic device (1 5) according to the present invention, wherein the antenna (1) comprises two coils (2) printed on the same substrate (28) ), (27). The type of the substrate (28) is the same as the type printed on the substrate (4) of the employee's consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, but the only difference is that the thickness of the substrate must be approximately larger than that of FIG. 1 The thickness of the substrate (4) is shown. In fact, because the coils (2), (27) are arranged on each side (29), (30) of the substrate (28), so that the two coils are in a relative manner, the coils may therefore be disadvantageous. Stray capacitive coupling to the reception quality of the antenna (1). As mentioned above, the degree of coupling of the capacitor depends on the width of the individual windings of the coils (2) and (27), and the operating frequency. Those skilled in this technology are adjusting the thickness of the substrate (28) in order to find out the space requirements of the antenna (1) and the capacitive coupling. The antenna (1) receives the paper standard applicable to the Chinese National Standard (CNS) A4 specification (21〇 > <; 297 mm) 3-_ 200301025 A7 B7_ __ 5.

Description of the invention (l) l The second wire (27) on the back (30) of the substrate (28). In this way, because the same magnetic field is applied to each coil (2) ), (27) and (read the notes on the back first and then fill out this page) the respective induced currents generated have the same flow direction, and therefore they are added together before processing the radio broadcast signal. Received by the circuit (22). Please also note that, because the coils (2) and (27) are not stacked in the configuration shown in Figure 3, the risk of capacitive coupling is reduced when compared to a configuration where the windings are stacked. The manufacturing method of the antenna (1) shown in FIG. 3 is similar to the manufacturing method of the antenna shown in FIG. Similarly, the configuration of the antenna has the same requirements as the configuration of the antenna shown in FIG. 2 described earlier. The previous description printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs corresponds to the preferred embodiment of the present invention, and the description should not be regarded as limiting the present invention, especially when the antenna contains several coils, the description should not be It is considered that the number of coils and the relative arrangement between the coils are limited. In fact, we can use an antenna such as one with two wires supported by two different substrates, and mount the substrates on two different sides of the housing of the portable electronic device according to the present invention, respectively. In other words, in the case of a wristband having two wristband components, each of the two coils can be installed in a different wristband component. In this case, of course, some additional contacts and some additional metal paths must be provided on the printed circuit board.
