Abstract
The utility model provides an earphone socket connector which can change one-way telecommunication output to two-way telecommunication output. The device is characterized in that a plug, two sockets, two resistors and two capacitors are combined inside one injection molding casing body. The utility model, which is particularly suitable for simultaneously listening to one cassette player with two sets of stereophones, has the advantages that impedance is well matched, and that use is flexible and convenient.
Description
The present invention relates to a kind of multiduty telecommunication equipment output connector along separate routes, particularly a kind of earpiece type cassette player single channel that is applicable to is exported the connector that becomes two-way output.
Existing cassette player is only established an earphone output plughole, can only supply single listening to, and can not satisfy the needs of listening to of two people, one machine.A large amount of telecommunication stereo sets that market provides all have only an output socket.Obtain two-way when output simultaneously at needs, all for want of suitable conversion element and can't realizing.
Task of the present invention is that a kind of multiduty interconnecting devices will be provided.It can be realized the output of single channel sound equipment is converted into the purpose that two-way is exported simultaneously, and can obtain good stereophonic effect under the prerequisite that guarantees impedance matching.
Task of the present invention realizes as follows: with a plug, two sockets and after two resistance, two electric capacity impedance matchings in accordance with regulations connect, be combined among the injection-moulded housing.Plug can be pegged graft with the delivery outlet of stereo set.Two sockets are pegged graft simultaneously for two set of headphones.Output electric signal is through resistance-capacitance circuit coupling dispensing two earphones.Reach the effect that two people listen to simultaneously.
Below with reference to accompanying drawing invention is described in further detail.
Fig. 1 is circuit theory diagrams of the present invention.
Fig. 2 is a kind of concrete structure schematic diagram of the present invention.
With reference to Fig. 1, R is a metalfilmresistor, and C is a high-frequency bypass capacitor, J
OBe cassette player output dual track plug receptacle, J
ABe the plug receptacle ［ 2 ］ of earphone, J
BBe earphone plug receptacle ［ 3 ］.The element assembling is as a whole in the frame of broken lines.Concrete installation site is referring to Fig. 2.There is screw locking-type plug ［ 5 ］ two sockets of setting-in ［ 2 ］ and ［ 3 ］ in injection-moulded housing ［ 1 ］ on the housing cover ［ 4 ］.Leave the space of about 10～20mm between socket ［ 2 ］ and ［ 3 ］, in order to attaching resistance R and capacitor C.Outwards there is boss at cover plate screw place, and high 2～5mm is not so that plug ［ 5 ］ and delivery outlet are subjected to the obstruction of surrounding structure when pegging graft.Plug ［ 5 ］ is inserted the cassette player output plughole, two headset plugs are inserted socket ［ 2 ］ and ［ 3 ］ respectively, just can listen to the output signal of a cassette player simultaneously by two set of headphones.Do coupling and power attenuation in order to take into account resistance, the R value can (0.25～1) of an earphone coil impedance doubly about, the value of shunt capacitance C can be about 0.5UF～30UF.Respectively carry out series matching by different type of machines and different earphone impedance.
