Abstract
The utility model discloses an earphone cord for realizing simulating a television handset antenna. The device comprises an earphone connector and an antenna, wherein two antennas are arranged on the earphone connector, the two antennas need to be winded with other signal lines, the antennas are insulating to the signal lines, and the earphone connector is connected with a ground wire. The 40cm antenna mainly used for covering low frequencies, the 13cm antenna is mainly used for covering high frequencies, so the earphone antennas can cover whole frequency ranges from high frequencies to low frequencies, and the television handset can successfully receive signals of various frequency points. The earphone cord is low in cost and saves space.
Description
Technical field
The utility model relates to a kind of antenna, relates in particular to the device that a kind of earphone cord is made the analog television mobile phone antenna.
Background technology
Along with popularizing of mobile TV, analog television mobile phone is owing to technology maturation, and cost is low, and free grade of rating still enjoys people to like.The mobile TV antenna is used telescopic antenna more at present, take the very big space of mainboard, and cost is comparatively speaking than higher.The utility model mainly is to transform by the common headphones line to replace telescopic antenna, can save the mainboard space, and view reception effect and telescopic antenna are suitable, and cost is also lower.
Summary of the invention
Adopt telescopic antenna at existing mobile TV antenna, the purpose of this utility model is to provide a kind of low cost, and a kind of earphone cord in space-efficient is realized the device of analog television mobile phone antenna.
The utility model is achieved by the following technical solution.
A kind of earphone cord is realized the device of analogue mobile phone television antenna, comprise: headset connector, antenna, set up two strip antennas on the described headset connector, these two antennas need and other holding wires around together, insulation each other, headset connector and ground wire connect together.We make the FM antenna with the GND of earphone cord usually, and the FM frequency range is relatively low, mainly cover 87M ~ 108M.And simulated television covers the relative broad of frequency band, and frequency range is 50M-870MHz, and common earphone antenna can not satisfy the TV performance requirement of high frequency.Concerning analog television mobile phone, we also can utilize a kind of special earphone cord to make antenna, relation according to frequency and wavelength, we can increase by two RF lines again on common headphones GND, length is respectively 40cm and 13cm, and 40cm mainly covers lower frequency, and 13cm mainly covers higher frequency, earphone antenna can cover the low frequency whole frequency from high frequency basically like this, makes the TV mobile phone can receive the signal of various frequencies smoothly.
Description of drawings
Fig. 1 is the utility model handset earphone schematic block circuit diagram
The number in the figure explanation
1-headset connector;
2-antenna.
Embodiment:
As shown in Figure 1, set up two strip antennas 2 on the described headset connector 1, these two sky 2 lines needs and other holding wires insulate each other around together, and headset connector 1 and ground wire connect together.
,The RF line that two antenna lengths that increase are 40cm and 13cm needs at the headset connector place and original ground wire connects together.40cm mainly covers lower frequency, and 13cm mainly covers higher frequency, and earphone antenna can cover the low frequency whole frequency from high frequency basically like this, makes the TV mobile phone can receive the signal of various frequencies smoothly.
Claims (2)
1. an earphone cord is realized the device of analogue mobile phone television antenna, comprise: headset connector, antenna, it is characterized in that: set up two strip antennas on the described headset connector, these two antennas need and other holding wires around together, insulation each other, headset connector and ground wire connect together.
2. a kind of earphone cord according to claim 1 is realized the device of analogue mobile phone television antenna, it is characterized in that: two antenna lengths of described increase are 40cm and 13cm; 40cm mainly covers lower frequency, and 13cm mainly covers higher frequency.
