Abstract

(57) [Abstract] [Problem] To be able to move freely on the stage while checking a monitor sound, and to prevent the sound image of the monitor sound from being localized in the center of the head. SOLUTION: An ear monitor system 1 is transmitted to a transmitter 2
, Receiver 3, distribution adder 4, left and right earphones 5
And The distribution adder 4 is incorporated in the receiver 3 and divides the collected monaural sound signal into two systems of signals corresponding to the left and right earphones 5 and generates one of them as a signal different from the other. For example, a difference is provided by using a delay circuit and delaying in time. The sending and receiving units 2 and 3 wirelessly transmit the acoustic signal. The sound of the performer P at the concert venue is picked up by the microphone 6 and the mixing device 7, sent as a monaural sound signal, transmitted through the receivers 2 and 3, and transmitted as different signals from the left and right earphones 5 by the distribution adder 4. Is output separately. The player P can move freely, does not affect the performance sound to the audience, and also avoids a single point localization in the head.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an ear monitor system for a singer or a musical instrument player on the stage to listen to a monitor sound.

[0002]

[Prior art]

 Conventionally, as shown in FIG. 5, a monitor speaker M for a player P to check his / her own musical tone is provided on a stage S toward the player P.

[0003]

[Problems to be solved by the invention]

 In the above-mentioned conventional monitor speaker, since the installation position is fixed, when the player P moves on the stage S and separates from the monitor speaker M as shown by a broken line in FIG. It becomes difficult. On the other hand, if the number of monitor speakers M is increased or the volume is increased in order to listen to the monitor sound at a distant position, the tone of the audience to which the monitor sound should normally be heard is hindered. On the other hand, it is possible to listen to the monitor sound by outputting the monitor sound from a simple monaural earphone that does not depend on stereo transmission, instead of outputting the sound from the speaker. And the sound image is fixed in the head, which is a so-called single point localization in the head. Especially when this state continues for a long time, it causes remarkable discomfort. Therefore, the present invention allows the player to move freely on the stage, does not disturb the audience's musical sound, prevents the player's monitor sound from being localized in the head, and confirms the monitor sound without discomfort. It is an object of the present invention to provide a relatively simple ear monitor system that can perform such operations.

[0004]

[Means for Solving the Problems]

 In order to solve the above problem, in the first invention, the transmitter 2 transmits an acoustic signal in which the musical sound of the player P is collected in monaural as a radio wave, and the receiver 3 attached to the player P Upon receiving the acoustic signal, the distribution adder 4 connected to the receiver 3 generates two different acoustic signals, and the performer P listens to the left and right acoustic signals with the earphone 5 separately from the left and right, so that the inside of the head of the sound image is obtained. The ear monitor system 1 was configured to prevent discomfort due to localization. In the second invention, the distribution adder 4 is configured so that one of the left and right acoustic signals is temporally delayed from the other. In the third invention, the distribution adder 4 is configured so that one of the left and right acoustic signals has a phase difference with respect to the other. In the fourth invention, the distribution adder 4 is configured so that one of the left and right acoustic signals has a frequency characteristic difference with respect to the other. In the fifth invention, the distribution adder 4 is configured so that one of the left and right acoustic signals has an output volume difference with respect to the other. In the sixth invention, the distribution adder 4 is configured so as to provide a difference between the left and right audio signals by combining any two or more of the above means.

[0005]

[Embodiment of the invention]

 An embodiment of the present invention will be described with reference to the drawings. In FIG. 1, an ear monitor system 1 includes a transmitter 2, a receiver 3, a distribution adder 4, and left and right earphones 5. For example, a sound emitted by a player P on the stage of a concert hall is picked up through a microphone 6, adjusted as a sound signal by a mixing device 7, output to a speaker, and heard by an audience. And is output to the left and right earphones 5 to be heard by the player as a monitor sound.

The distribution adder 4 is built in the receiver 3, and as shown in FIG. 2, divides the monaural sound signal into two signals corresponding to the left and right earphones 5, and adds a built-in additional circuit 8. To generate one of them as a different signal from the other. In the processing of the acoustic signal by the additional circuit 8, a difference is provided by providing a slight time delay using, for example, a delay circuit.

The transmitter 2 is connected to the mixing device 7, and sends the output signal of the mixing device 7 to the receiver 3 by radio. The receiver 3 is mounted on the player P in advance and receives an acoustic signal by radio waves. This acoustic signal is output from the earphone 5 through the distribution adder 4 as a sound that is left and right different. Therefore, the player P can move freely within the range of the radio wave. Since the monitor sound is output from the earphone 5, it does not affect the performance sound emitted from the speaker, can be heard as being different from the left and right, and localization of the sound image at the center in the head is avoided.

FIG. 3 shows a second embodiment. In the distribution adder 4 of the ear monitor system 1, two types of additional circuits 9 a and 9 b are provided in two systems corresponding to the left and right earphones 5. Also in this case, a time delay can be provided between the signals.

FIG. 4 shows a third embodiment. In the distribution adder 4 of the ear monitor system 1, additional circuits 10a and 10b are provided in two systems corresponding to the left and right earphones 5, respectively, and an additional circuit 10c is provided therebetween. The additional circuit 10c performs link operation of two different signals processed by the additional circuits 10a and 10b.

Note that the signals corresponding to the left and right earphones 5 are provided with a phase difference, a volume difference, a difference in frequency characteristics, and the like between the signals in addition to the time delay between the signals as described above. The combination can be different from each other.

[0011]

[Effect of the invention]

 As described above, according to the present invention, the monitor sound can be recognized even if the user freely moves on the stage, and the sound to the audience is not disturbed. Therefore, it is possible to prevent an unpleasant sensation caused by localization at a central point in the head of a sound image specific to monaural sound.
