Abstract
The invention discloses a headset cascading device. The cascading device comprises a shell body; a headset plug is arranged at one end of the shell body; a set of headset jacks is arranged at the other end of the shell body; a power amplifier is arranged in the shell body; the headset plug inputs audio signals to the input end of the power amplifier; the power amplifier respectively sends the amplified audio signals to each headset jack; each headset jack is connected with a headset; therefore, the audio on the same device can be shared by people; the damped audio signals can be amplified through the power amplifier; and the output sound quality is ensured.
Description
Technical field
The present invention relates to Headphone accessory, specifically a kind of earphone cascade device.
Background technology
Known, the electronic equipments such as mobile phone, computer, PAD, MP4 all have COBBAIF, are also earphone jack, just can realize the output of audio frequency by earphone jack frames connecting with headphone. But on these smart machines, generally all only have at present an earphone jack, so can only insert an earphone for a people, have no idea to make people to share the audio frequency on same audio frequency apparatus.
Summary of the invention
The object of the present invention is to provide a kind of earphone cascade device, this cascade device can connect multiple earphones, makes multiplePeople altogetherEnjoy the audio frequency on same audio frequency apparatus.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of earphone cascade device, comprise housing, one end of housing is provided with a headset plug, the other end of housing is provided with one group of earphone jack, described enclosure interior is provided with a power amplifier, headset plug inputs to audio signal the input of power amplifier, and the audio signal after amplifying is sent to respectively each earphone jack by power amplifier.
As the distortion of technique scheme, also can expand following technical scheme:
A kind of earphone cascade device, comprise housing, one end of housing is provided with a headset plug, the other end of housing is provided with one group of earphone jack, described enclosure interior is provided with one group of power amplifier, described power amplifier is corresponding one by one with earphone jack, and headset plug inputs to audio signal the input of each power amplifier, and the audio signal after amplifying is sent to respectively corresponding earphone jack by power amplifier.
The invention has the beneficial effects as follows, each earphone jack all can connect an earphone, thereby makes people can share the audio frequency on same equipment, can amplify the audio signal of decay by power amplifier, ensures the tonequality of output.
