The utility model has the advantages of simple structure, small size and low cost, which can not only be used by one person but also can be used by two people.
Description
The utility model relates to a kind of transducer, especially for the stereophone of radio and tape player or walkman.
Existing walkman stereophone, generally all adopt the external pair of output of a plug, the earphone of this structure, it still is more satisfactory that the individual uses, but if want two people to appreciate a program or song simultaneously, will external a pair of little audio amplifier, cost is increased, volume increases, the influence of environmental noise in addition, and stereosonic effect is also just much poor.
The purpose of this utility model is to overcome the existing few shortcoming of earphone output, provides a kind of practical, and volume is little, the double-purpose stereophone that cost is low.
Characteristics of the present utility model are to establish two pairs of outputs on the plug of existing stereophone, also set up an earphone socket or switch on the pair of output wherein; Pair of output is directly joined with a pair of earplug by lead, and another then is connected with earphone socket or switch to output.
With embodiment the utility model is elaborated with reference to the accompanying drawings.
Fig. 1 is the utility model structural representation.
Among the figure 1, headset plug 2, earphone socket or switch 3,4, output 5, earplug 6, housing.
Stereophone with reference to Fig. 1, on plug 1, draw two pairs of outputs 3,4, also be provided with earphone socket or switch 2 on the pair of output wherein, output 4 directly is connected with earplug 5,3 of outputs are connected on earphone socket or the switch 2, output termination 3,4, socket or switch 2 all are fixed in the housing 6.During use plug 1 is inserted in the earphone jack of radio and tape player, voice signal just enters on earplug 5 and socket or the switch 2 by output lead.As think that two people listen to simultaneously, and join an earphone that same impedance is arranged again, insert on socket or the switch 2, can reach the purpose of listening to jointly.
The utility model is simple in structure, and cost is low, can be used on radio and tape player, the television set, and practical, volume is little, is easy to carry, and not only can singlely use, and can two people listen to.
