It is a schematic explanatory drawing of an electric circuit. FIG. 7 is a front view of a portable receiving device showing another embodiment of the present invention.

  Hereinafter, an embodiment of the present invention will be described based on FIGS. 1 to 3. 1 is a portable radio receiver as a portable receiving device of the present invention. The portable radio receiver 1 receives an FM broadcast, and an antenna 29 described later receives an FM broadcast. The portable radio receiver 1 is configured to have a right case 2, a left case 3, and a neckband 4.

  A right sound emission hole 5 is formed on the front side of the right housing 2. Further, the right speaker 6 is incorporated in the right case 2. The sound generated by the right speaker 6 is emitted from the right sound emission hole 5 to the outside of the right case 2. Furthermore, a battery 7 serving as a power source for operating the portable radio receiver 1 is exchangeably accommodated in the right case 2. In the case of this example, the number of the batteries 7 is two, but it may be one or three or more. Further, in the case of this example, the battery 7 is a dry battery, but may be another primary battery or a secondary battery.

  A left sound emission hole 8 and a display window 9 are provided on the front side of the left housing 3. Further, on the front side of the left housing 3, tuning buttons 10 and 11 and preset buttons 12, 13 and 14 are provided. Further, a dial 15 protrudes from the left side surface of the left housing 3. A circuit board 16 including a tuning circuit is built in the left case 3. The tuning switches 17 and 18, the preset switches 19, 20 and 21, the on / off switch 22 and the variable resistor 23 are mounted on the circuit board 16. The on / off switch 22 and the variable resistor 23 are actually one element. The tuning switches 17 and 18 can be pressed by the tuning buttons 10 and 11, respectively. Similarly, the preset switches 19, 20, 21 can be pressed by the preset buttons 12, 13, 14, respectively. The on / off switch 22 and the variable resistor 23 are operated by rotating the dial 15. Further, a liquid crystal display element 24 and a left speaker 25 are connected to the circuit board 16. The liquid crystal display element 24 and the left speaker 25 are incorporated in the left case 3. Then, the liquid crystal display element 24 is visually exposed from the display window 9. Further, the sound generated by the left speaker 25 is emitted from the left sound emission hole 8 to the outside of the left housing 3. The circuit board 16 is connected to a pair of feed lines 26, a pair of right signal lines 27, a pair of left signal lines 28, and an antenna 29. The left signal line 27 electrically connects the circuit board 16 and the left speaker 25.

  The neck band 4 is formed of an elastically deformable and non-slipperable elastomer or the like. And this neck band 4 is formed in a C-shape in which both ends are substantially parallel in a front view. That is, even if the neck band 4 is deformed by an external force, it is restored to the original C shape when the external force is removed. Further, as shown in FIG. 2, the neck band 4 is curved backward in a side view in a posture in which both ends 4R and 4L are vertical. That is, when the portable radio receiver 1 is worn on the body, the neckband 4 is formed to conform to the shape from the neck to the shoulder. And, by forming the neckband 4 in such a shape, when the portable radio receiver 1 is worn on the body, the neckband 4 contacts clothes or skin in a wide range. . Furthermore, the right case 2 is attached to the right end 4R of the neckband 4 and the left case 3 is attached to the left end 4L. The right end 4R of the neckband 4 is fixed in a state of being inserted into the right case 2. Similarly, the left end 4L of the neck strap 4 is fixed in a state of being inserted into the left housing 3.

  Further, the feeder 26, the right signal line 28, and the antenna 29 are wired in the neck band 4. In the neck band 4, the feed line 26 and the right signal line 28 are wired at a predetermined distance from the antenna 29. The feed line 26 electrically connects the circuit board 16 built in the left housing 3 and the battery 7 housed in the right housing 2. Similarly, the right signal line 27 electrically connects the circuit board 16 built in the left case 3 and the right speaker 6 built in the right case 2. On the other hand, the base end 29 P of the antenna 29 is electrically connected to the circuit board 16, and the tip end 29 D of the antenna 29 is located at the right end 4 R of the neckband 4. Thus, by arranging the antenna 29 in the neck band 4, it is safe because there is no need to provide a projection for the antenna. And, as described above, since the right end 4R of the neck band 4 is fixed in the right case 2, it is positioned in the right case 2, but it extends to a point beyond the right end 4R. I will never leave. As described above, by extending the antenna 29 from the left housing 3 to the right end 4R of the neck band 4, the length of the antenna 29 can be made long, so that the reception sensitivity can be enhanced. On the other hand, by making the end 29D of the antenna 29 up to the right end 4R of the neckband 4, there is no need to fix the end 29D of the antenna 29 in the right case 2, thereby facilitating manufacture. In addition, the influence of static electricity on the antenna 29 from the battery 7 accommodated in the right case 2 can be eliminated. Therefore, by setting the end 29D of the antenna 29 to the right end 4R of the neck band 4, the best balance between reception performance, electrical safety and manufacturing cost can be obtained.

  Reflectors 30 are provided on the side surfaces of the right case 2 and the left case 3 respectively. A reflector 31 is also provided at the central portion of the neck band 4. When the portable radio receiver 1 is mounted on the user's body, the reflectors 30 face left and right, and the reflector 31 faces back. Therefore, these reflectors 30 and 31 reflect the light from the left and right and the rear. Thus, when the user uses the portable radio receiver 1 when exercising outdoors at night, the light of the headlight of an automobile or the like is reflected to inform the driver of the presence of the user. be able to.

  Next, the operation of the present embodiment will be described. First, the user holds the portable radio receiver 1 on his neck. At this time, by setting the right case 2 to the right of the user and the left case 3 to the left of the user, the sound release holes 5 and 8 are released in the direction of the user's ear. Further, as described above, since the right case 2 and the left case 3 are respectively provided at both ends 4R and 4L of the neck band 4, they can be used in a well-balanced manner. From this state, by operating the dial 15 to turn on the on / off switch 22, the broadcast wave received by the antenna 29 is demodulated into an audio signal by the receiving circuit on the circuit board 16, and further After being amplified by an amplifier circuit (not shown) on the circuit board 16, the right signal line 27 and the left signal line 28 pass through, and the sound is converted to voice by the right speaker 6 and the left speaker 25. As described above, since the tip 29D of the antenna 29 extends to the right end 4R of the neckband 4 and the length of the antenna 29 is sufficiently long, the reception sensitivity is enhanced. Broadcast waves can be well received. The volume of the sound emitted from the right speaker 6 and the left speaker 25 can be adjusted by operating the variable resistor 23 using the dial 15. Immediately after the on / off switch 22 is turned on, the broadcast wave of the previously selected broadcast station is set to be received. Then, the channel selection operates the tuning switches 17 and 18 using the tuning buttons 10 and 11 or operates the preset switches 19, 20 and 21 using the preset buttons 12, 13 and 14. It takes place in The liquid crystal display element 24 displays the frequency of the selected broadcasting station, the remaining battery capacity, the number of the preset broadcasting station, and the like.

  The right housing 2 and the left housing 3 are located near the collarbone of the user when the portable radio receiver 1 is mounted on the user's body. That is, the right speaker 6 and the left speaker 25 are positioned below and close to the user's ear. Therefore, even if the volume is low, the user can listen to the sound emitted from the right speaker 6 and the left speaker 25. On the other hand, even if the volume of the sound emitted from the right speaker 6 and the left speaker 25 is low, the user can sufficiently listen to the sound. The sound emitted from the speaker 25 can be made hard to hear. For this reason, if there is a certain distance, even if there are other people around, it is less likely to be annoying. Further, since the portable radio receiver 1 does not block the user's ear, the user can simultaneously hear surrounding sounds. Therefore, the safety of the user using the portable radio receiver 1 can be enhanced.

  As described above, although the right case 2 and the left case 3 are respectively provided at both ends 4R and 4L of the neck band 4, the right case 2 and the left case are provided in order to improve the balance between the left and right. The housing 3 has slightly different weights because the elements housed in the housing or replaceably are different. In the case of this example, the right case 2 in which the battery 7 is accommodated is somewhat heavier than the left case 3. Therefore, when the portable radio receiver 1 is attached to the user's body, a force acts to lower the right case 2 side by gravity. However, as described above, the neck band 4 is formed of a non-slipperable elastomer or the like, and is formed to be curved along the shape of the neck to the shoulder, so that the contact area with clothes or skin is Since it can be enlarged, it can exert sufficient frictional force with clothes or skin when worn on the user's body. Therefore, even if the weight of the right housing 2 and the left housing 3 is somewhat unbalanced, it is possible to prevent the right housing 2 from sliding down. For this reason, even if it receives a light exercise or house vibration or shock, the right case 2 and the left case 3 can be kept at substantially the same position.

  As described above, the portable radio receiver 1 as the portable receiving apparatus of the present invention is connected to the right case 2 and the left case 3 and these cases 2 and 3 and has a shape that can be necked. In addition, it is incorporated in the elastically deformable neck band 4, the right speaker 6 and the left speaker 25 provided in each of the housings 2 and 3, and the battery 7 and the left housing 3 accommodated in the right housing 2. And the antenna 29 connected to the receiving circuit of the circuit board 16 is incorporated in the neck band 4 so that the antenna 29 in the neck band 4 can be used. Since the audio signal received and demodulated by the receiving circuit can be voiced and heard by the speakers 6 and 25 provided in the respective cases 2 and 3 located below the user's ear at the time of wearing. , The user does not block their ears And while listening to the sound of the TV, it is possible to hear ambient sound.

  Further, the portable radio receiver 1 is provided with the neck band 4 so as to connect the right case 2 and the left case 3, and both the right case 2 and the left case 3 are provided with the neck band 4. A right speaker 6 and a left speaker 25 are provided, the battery 7 is housed in the right housing, the circuit board 16 is built in the left housing, and the antenna is connected from the left housing 3 to the right housing. By being passed through the neck band 4 toward the body 2, it can be used in a well-balanced manner when worn by the user.

  Furthermore, the front end 29D of the antenna 29 extends from the circuit board 16 provided in the left housing 3 to the right end 4R in the necking band 4, thereby facilitating manufacturing while enhancing reception sensitivity. be able to.

  The present invention is not limited to the above embodiment, and various modifications can be made within the scope of the invention.
