The present invention relates to a stereo headphone, and more particularly, to a multi-speaker headphone device capable of listening to multiple audio signals, such as four-channel stereo with headphones.

Stereo headphones are widely used as speaker systems for listening to audio signals as is well known.

A conventional stereo headphone has an RCH earphone 12 for converting the phone program 10 and R channel (hereinafter referred to as "RCH") sound and L channel or below "LCH" sound into an audible sound as shown in FIG. And an LCH earphone 14.

At this time, a line is connected to each of the RCH and LCH earphones 12 and 14 so as to input only a sound source of a corresponding channel from the phone program 10.

The block diagram of the conventional stereo headphones having the same structure as the first diagram is the same as the second diagram.

Reference numerals 16 and 20 denote R amplifiers and L amplifiers for inputting the RCH signal and the LCH signal, respectively, and amplifying and outputting them to a predetermined level.

And 18 and 20 are speakers of RCH and LCH.

Conventional stereo headphones as shown in FIGS. 1 and 2 provide only sound of two channels, LCH and RCH.

That is, when the LCH and RCH audio signals are output from the audio system (not shown), they are separated through the phone frog 10, and then the RCH audio signals are transmitted to the R amplifier 16, and the LCH audio signals are transmitted to the L amplifier 20. ) And amplified output.

The audio signals amplified by the R and L amplifiers 16 and 20 are converted into audible sound by the RCH speakers 18 and LCH speakers 22 connected to the respective output terminals.

However, in the conventional stereo headphones as described above, there has been a problem in that the output of a multi-sound audio system that outputs a multi sound cannot be completely reproduced and output.

Modern audio systems are designed to output stereo RCH and LCH stereo sound as well as surround signals and surround sound effects (EFFECT SOUND).

Therefore, when listening to the output of the system for outputting the effect sound only with conventional stereo headphones such as the first and second degree, by listening only the RCH, LCH stereo sound, the output audio of the multisound system, for example RCH, The surround signal of the LCH was not sufficiently digested.

Accordingly, an object of the present invention is to provide a multi-speaker headphone that can reproduce the multi-sound output from the multi-sound output audio system.

Another object of the present invention is to provide a stereo headphone that reproduces and outputs two or more amplifiers and speakers corresponding to each channel of the RCH and LCH output from an audio system to output surround sound. .

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

3 is a structural diagram of a multi-speaker headphone according to the present invention, a phone plug 10 for inputting an RCH audio signal and an LCH audio signal output from a multisound audio system (not shown), and at least two amplifiers and speakers. And a first and second speaker cabinets 30 and 32 for respectively outputting two different sounds by inputting the RCH voice signal and the LCH voice signal provided from the phone plug 10, respectively. do.

In the above configuration, the phone plug 10 and the first and second speaker cabinets 30 and 321 are connected by RCH and LCH audio lines, respectively.

4 is a block diagram of the multi-speaker headphones of FIG. 3, where 10 is a phone plug and 30 and 32 are blocks of the first and second speaker cabinets.

In this case, each of the first and second speaker cabinets 30 and 32 may include a main amplifier 42, 50, a sub amplifier 46, 54, a main speaker 44, 52, and a sub speaker 48, 56. Have

During the fourth period, the phone plug 10 is configured to input a main voice signal (RAM) and a sub signal (RSS) of the RCH, a main signal (LAM) and a sub (LSS) of the LCH through a desired voice signal. It should be noted that such a configuration can be easily constructed by those skilled in the art who can construct a conventional stereo phone plug.

The R main amplifier 42 inputs only the RCH main signal RMA among the RCH signals RS, and the R sub amplifier 46 inputs only the RCH sub-signals RSS among the RCH signals RS. It is connected to (10).

On the other hand, the L main amplifier 50 inputs only the LCH main signal LMA among the LCH signals LS, and the L sub amplifier 54 inputs only the LCH sub-signals LSS among the LCH signals LS. It is connected to (10).

Reference numerals 44 and 52 are RCH and LCH main speakers, and 48 and 56 are sub speakers of RCH and LCH.

Now, an output jack of a multisound audio system (not shown) which outputs an RCH signal RS including a main signal and a sub signal of an RCH, and an LCH signal LS including a main signal and a sub signal of an LCH. When the phone plug 10 of FIG. 3 or FIG. 4 is inserted, the RCH signal RS and the LCH signal LS are separately output from the phone plug 10.

At this time, the separate output from the phone plug 10 as described above is the same as the separate output from the normal stereo phone plug.

At this time, the RCH signal RS and the LCH signal LS separated from the phone plug 10 are respectively the main signals RMA, LMA and the sub-signals RSS and LLS of each channel signal. The signal includes.

Therefore, the main signal RMA and the sub-signal RSS of the RCH signal RS are heavily output from the R main amplifier 42 and the R sub amplifier 46 so that the RCH main and RCH sub-speakers 44 and 48 In each playback output.

Meanwhile, the main signal LMA and the sub signal LSS of the LCH signal LS separated from the phone plug 10 are amplified and output from the L main amplifier 50 and the L sub amplifier 54, respectively. It is output through the LCH main and sub speakers 52 and 56.

Therefore, the multi-sound output from the output jack of the multi-sound audio system is reproduced and separated into main and sub-signals of each channel in the multi-speaker headphones configured as shown in FIG.

5 is a circuit diagram of another embodiment according to the present invention except that the R sub amplifier 46 and the L sub amplifier 54 are designated as the R surround amplifier 46 'and the L surround amplifier 54' during the above-described fourth embodiment. The code and configuration are the same.

Therefore, even if the signal of each channel from the multi-sound audio system is output to the main and surround sound, it can be operated as a surround headphone.

6 is a circuit diagram of another embodiment according to the present invention, in which the phone plug 10 is a stereo phone plug for inputting the RCH signal R and the LCH signal L as usual, and the R main amplifier 42 and R The sub amplifier 46 is replaced by the high pass filter 42a and the low pass filter 46a, and the L main amplifier 50 and the L sub amplifier 54 are the high pass filter 50a and the low pass filter 54a. Are replaced by).

When the normal RCH signal R and the LCH signal L are input to the phone plug 10 in the configuration as shown in FIG. 6, the RCH signal R is input to the high pass filter 42a and the low pass filter 46a. The LCH signal L is input to the high pass filter 50a and the low pass filter 54a.

At this time, only the high pass signal in the RCH signal R passes through the high pass filter 42a, and only the local signal in the signal band included in the RCH signal R passes through the low pass filter 46a.

Therefore, only the high sound in the RCH signal R is reproduced by the main speaker 44 of the RCH, and only the low sound in the RCH signal R is output by the RCH sub-speaker 48.

Meanwhile, another high pass filter 50a and a low pass filter 54a input LCH signals L from the phone plug 10 to separate and pass high and low frequencies to the LCH main and sub speakers 52 and 56. The high and low signals are output from, respectively.

Therefore, the signal source of each channel is reproduced as a wofer and a tweeter.

As described above, the present invention constructs a multi-speaker headphone by incorporating at least two speakers and each amplifier capable of driving the speakers in one speaker cabinet, so that the multi-sound and bass and treble are output from the multi-sound audio system. There is an advantage to improve the function of the headphones by separating the playback.
