Abstract
A flashlight with radio and adopting a hanging rope antenna comprises a built-in radio circuit and further comprises a hanging rope. A metal wire as an antenna is arranged in the hanging rope. The flashlight is in mechanical bearing connection with the hanging rope through a connection rope, and the radio circuit in the flashlight is in electrical connection with the hanging rope antenna through a metal lead wire. The flashlight has the advantages that the hanging rope antenna is connected with the flashlight through the connection rope, users do not need to insert an earphone connection wire as the antenna, so that the flashlight is flexible to use. Further, the hanging rope antenna is connected with the flashlight through the connection rope, so that damage to the hanging rope antenna caused by frequent swinging between the flashlight and the hanging rope can be avoided, and service life of the hanging rope antenna can be prolonged.
Description
Technical field
The utility model relates to a kind of flashlight that has radio function.
Background technology
Have the part flashlight to have the FM FM receiver function on the market, broadcast listening when being particularly suitable in the open air also becomes a kind of trendy product.Because FM is operated in 3 metric wave frequency ranges, length the best of antenna is about 75cm, so the realization of function of radio receiver need be used external antenna.In the prior art, usually adopt earphone output line to serve as external antenna, when earphone inserted, the output line of earphone was connected to the antenna input of radio reception circuit through high frequency capacitance.But cause a problem like this, when the built-in loudspeaker that use product are exported as audio frequency, also need insert the output line of earphone, otherwise just influence the radio reception effect, this causes the inconvenience of use.
Summary of the invention
The purpose of the utility model is to disclose a kind of band radio reception flashlight that the earphone line just can be realized function of radio receiver that need not to insert.
The present invention includes the flashlight that is built-in with the radio reception circuit, also include: a lanyard, lanyard inside has the metal wire as antenna; One connection cord, connection cord one end is attached to flashlight, and the other end is connected with lanyard through a fastener; One metal lead wire, metal lead wire one end is connected with metal wire in the lanyard through fastener, and the other end is connected to the antenna input of the radio reception circuit of flashlight.
Described lanyard plays the braid of stretch-proof effect by the outside and the plain conductor of braid the inside is formed.Braid adopts the braided material braiding to constitute.
Described metal lead wire skin is coated with protective layer.The length of metal lead wire is greater than connection cord.
The utility model adopts the lanyard be used to carry and hang flashlight originally, is used as reception antenna, can directly use built-in loudspeaker during broadcast listening like this, need not to insert the earphone line and makes antenna, uses more convenient flexible.And; Lanyard as antenna directly is not connected with flashlight; But be connected mechanical load-bearing effect with flashlight through a flexible connection cord; And the antenna in the lanyard in addition through a metal lead wire come with flashlight in the radio reception circuit do and be electrically connected, can avoid the frequent swing between flashlight and the lanyard like this and damage lanyard, prolong the service life of lanyard antenna.
Description of drawings
Fig. 1 is the structural principle sketch map of the utility model embodiment.
The specific embodiment
Among Fig. 1, the 1st, the existing flashlight that is built-in with the radio reception circuit, the 2nd, lanyard, existing lanyard is used as carrying or flashlight being suspended on the neck, can adopt plastic coated wire or braided material formation.The utility model is concealed with a metal wire as antenna in the centre of lanyard 2.Metal wire can adopt flexible strands of metal wire to constitute; Be coated with protective layer in the metal wire outside; Such as plastic layer, but better scheme is that the metal wire outside adopts braided material composition braid to be used as protective layer, has stronger stretch-proof effect; Play the load-bearing effect of suspension flashlight, with the metal antenna in the middle of protecting.Metal wire length is for receiving 1/4 of band wavelength, and the head and the tail two ends do not link to each other, and head end is in fastener 4 places.
If the direct connection hand torch of lanyard, frequent swing damages the antenna in the lanyard easily.So the utility model adopts a connection cord 3, one ends to be attached to the shell of flashlight 1, the other end is connected with lanyard 2 through a fastener 4.Connection cord 3 can adopt braided material to constitute, and is soft and tensile strength arranged, but but sub-thread also multiply use, Fig. 1 is bifilar use.Fastener 4 can adopt working of plastics, and connection cord 3 and lanyard 2 are fixed together.In addition; One metal lead wire 5; The employing strands of metal wire is formed, and the outside is coated with plastic layer or braid as protective layer, and metal lead wire 5 one ends are connected through the head end of the metal antenna in fastener 4 and the lanyard 2; The other end is connected to the antenna input of the radio reception circuit in the flashlight 1, and makes metal lead wire 5 length greater than connection cord 3.Like this, accomplish flashlight 1 by connection cord 3 and be connected, accomplish in the flashlight being electrically connected of antenna in the radio reception circuit and lanyard, can protect the lanyard antenna, increase the service life by metal lead wire 5 with the mechanical load-bearing of lanyard 2.
