The operation of (2) first embodiment
In above-mentioned mobile telephone system 1 shown in Figure 1; High frequency band tuner 13H and/or low-frequency band tuner 13L begin executable operations according to user's operation, and antenna input of high frequency band 13H and/or low-frequency band tuner 13L is connected with junction cable 2 via selection circuit 14.In mobile telephone system 1; The cable 19 of junction cable 2 and/or headset assembly 3 (being connected to junction cable 2) is as antenna; So that receive desired broadcast wave through high frequency band tuner 13H and low-frequency band tuner 13L, so that reproducing audio signal SAL and SAR.In mobile telephone system 1; By amplifier circuit 10L and 10R audio signal SAL and SAR are outputed to junction cable 2; Drive loud speaker 20L and 20R, and will present to the user by the voice of the received broadcast wave of high frequency band tuner 13H and/or low-frequency band tuner 13L.Therefore, the use of mobile telephone system 1 allows to enjoy various types of broadcasted contents through headset assembly 3.
In mobile telephone system 1, sequentially the cable 19 via high frequency elimination circuit 11L and 11R, junction cable 2 and headset assembly 3 outputs to loud speaker 20L and 20R with audio signal SAL and SAR.In said modules, in the base portion of agent set 4, provide high frequency to eliminate circuit 11L and 11R, so that stop high-frequency signal to get into agent set 4, wherein high-frequency signal is by cable 19 inductions such as grade.As a result, amplifier circuit 10L and 10R stably operate through for example making, and enjoying various types of contents becomes possibility.
On the other hand; In junction cable 2; Cable LL, LR and LG as the stranded wire part 15A of one of the parallel line in the path that is formed for transmitting high-frequency signal are formed for the path of transmitting audio signal SAL and SAR, and the ground wire that is used for audio signal SAL and SAR.As a result, stably transmitting audio signal SAL and SAR.
In addition, in junction cable 2, all be connected to antenna input of high frequency band tuner 13H and/or low-frequency band tuner 13L as each in the LA3 of the cable LA1 of the stranded wire part 15B of another parallel line.The result; The high-frequency signal of responding to LA3 owing to the cable LA1 by stranded wire part 15B causes high frequency band tuner 13H and/or low-frequency band tuner 13L to receive broadcast wave, another in the parallel line that said stranded wire part 15B is a junction cable 2.
Here, one of end of each bar of the cable LA1 of junction cable 2 in the LA3 (said end provides in earphone 3 sides) is open end (open end).In addition, cable LA1 each bar in the LA3 separates from the cable LG that is appointed as hop by filter circuit 17, and the other end (the said other end provides in agent set 4 sides) of each bar of cable LA1 in the LA3 is connected to agent set 4.Because each bar cable LA1 is connected to antenna input of each high frequency band tuner 13H and low-frequency band tuner 13L via capacitor 16 and selection circuit 14 to the above-mentioned other end of LA3; So the base portion through with agent set 4 is used as feed point, cable LA1 is used as unipole antenna to LA3.As a result, when the cable 19 of headset assembly 3 contacts (as shown in Figure 4) with human body, can prevent to touch human body to the corresponding part of LA3 (2) with cable LA1.Above-mentioned configuration allows to prevent to fall into by cable LA1 to receive the human influence to the broadcast wave in the frequency band that LA3 received, and makes the performance of mobile telephone system 1 improve.
In addition, in mobile telephone system 1, cable LL, LR and LG that provides in the hop side and the cable LA1 that provides in the antenna part side are to the parallel extension of LA3.Therefore, possibly get into each bar cable LA1 of providing in the antenna part side to LA3 via the cable LL that provides in the hop example, LR and LG by the high-frequency signal of the cable 19 (cable 19 is connected with junction cable 2 and extends) of headset assembly 3 induction.In this case, the cable 19 of headset assembly 3 becomes and is equivalent to antenna, and the performance of mobile telephone system 1 maybe be by human body deterioration.
Yet, in the above-described embodiments, comprise that the characteristic impedance value of the parallel line of antenna part and hop becomes about 166ohms.Therefore, for example, the impedance between the parallel line becomes obviously the impedance that obtains in the situation greater than the coaxial cable of the characteristic impedance of using 50ohms.As a result, can reduce fully cable LL, LR and LG that the hop side provides and at cable LA1 that the antenna part side provides to the coupling between the LA3.In addition, according to expression formula Z=276/ (ε
1/2) * log (d/a) calculates the characteristic impedance of parallel line, and between its center line is that 1.6 [mm] and lead radius are 0.4 [mm] apart from d.Here, symbol ε representes the dielectric constant between the line, and the logarithm truth of a matter that is expressed as log is 10.As a result, according to first embodiment, can suppress high-frequency signal and get into the cable LA1 that provides in the antenna part side to LA3 via the cable LL that provides in the hop side, LR and LG, wherein high-frequency signal is by the cable induced of headset assembly 3.As a result, the antenna part that can only make junction cable 2 is as antenna, and the performance that prevents mobile telephone system 1 is by human body deterioration stably.
In addition, in the above-described embodiments, the length L 1 of junction cable 2 is set to 1/4th of particular broadcast wavelength degree in the frequency band that falls into high frequency band tuner 13H.Therefore, in high frequency band tuner 13Hd frequency band, in the antenna part of junction cable 2 effectively the induction of high frequency signal and with high-frequency signal transmission to high frequency band tuner 13H, this has improved the performance as the junction cable 2 of antenna.
Especially, in the above-described embodiments, high frequency band tuner 13H receives the broadcast wave of digital radio broadcasting, and in the frequency band of digital radio broadcasting because human body has contacted significantly deterioration antenna characteristics.Therefore, if only with the antenna part side of junction cable 2 as the antenna in the frequency band of high frequency band tuner 13H, then as the situation of said embodiment, the performance of antenna becomes and is higher than the performance of the antenna that uses in the past significantly.In addition, even do not provide high frequency to eliminate circuit, can prevent that also mobile telephone system 1 receives the human influence conversely in earphone 3 sides.As a result, mobile telephone system has the configuration of more simplification and higher mechanical strength, and more more superior than design in the past.In addition, can reduce in the increase that is used for the dc impedance that the transmission of audio signals path occurs.
In addition, the length L 2 from plug 5 sides to loud speaker 20L is set to 1200 [mm], this is to fall into 1/4th of particular broadcast wavelength degree in the frequency band that is received by low-frequency band tuner 13L, this means that length L 2 is twices of the length of junction cable 2.According to above-mentioned configuration, the cable 19 of headset assembly 3 not as antenna work, receives the adverse effect of human body contact so that prevent cable 19 in the frequency band of high frequency band tuner 13H.As a result, cable 19 improves as antenna performance.
On the other hand, if low-frequency band tuner 13L is used to receive broadcast wave, then as follows with mobile telephone system 1 configuration.That is, in agent set 4 sides of junction cable 2, the cable LG that will be used for ground wire is connected to each bar cable LA1 to LA3 via filter circuit 17.Because the frequency that received of low-frequency band tuner 13L is lower than the frequency that high frequency band tuner 13H is received, so the identical amount of difference of the frequency that frequency that the impedance of filter circuit 17 reduces to be received with low-frequency band tuner 13L and high frequency band tuner are received.As a result, the hop side of junction cable 2 and the cable 19 that is connected to the hop side are as unipole antenna.Therefore, if the receive frequency of mobile telephone system 1 is very low, then having the unipole antenna of the electrical length of increase through use can receiving broadcast signal, and this has increased antenna gain and has improved the performance of mobile telephone system 1.
According to the above-mentioned configuration of first embodiment, both length of the cable of junction cable 2 and headset assembly 3 19 is set to 1/4th of the broadcast wave length that received by low-frequency band tuner 13L.Therefore, induction of high frequency signal effectively in the hop side of junction cable 2 and cable 19, and can be with high-frequency signal transmission to low-frequency band tuner 13L, this has improved the performance of mobile telephone system 1.
