Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a performance device which outputs performance sounds from all of a plurality of performance speakers.
The present invention relates to a performance device in which some speakers can be used for other special purposes.

[0002]

2. Description of the Related Art A performance device having a plurality of performance speakers and outputting a performance sound by using all of the speakers has been well known.

[0003]

However, in the above-mentioned conventional performance apparatus, when some of the speakers are used for other special purposes, for example, for calibration for measuring the acoustic characteristics of the surroundings, it is usually impossible. Since it was not taken into consideration, the following problems occurred in this case.

That is, in the calibration for measuring the acoustic characteristics of the surroundings, generally, a test sound of a predetermined volume (for example, a sound such as white noise or pink noise) is output from a speaker, and the reflected sound is collected. I analyze it by doing so. If such a calibration is performed using a performance sound output speaker, a test sound of the volume at which the performance sound was output is output from the speaker unless some volume control is performed during the calibration. Since it is output, accurate calibration cannot be performed. Therefore, in order to perform accurate calibration, it was necessary to set the volume for calibration again at the time of calibration. In particular, in a device configured to change the volume of all speakers with one master volume, the volume that is optimally adjusted to output the performance sound is
This is very troublesome for the user, because the volume must be changed every time calibration is performed, and when the calibration is completed, the original volume must be restored again. Also,
When the accuracy of the calibration depends on the set volume of the test sound, it is difficult to set the volume for calibration by the normal volume operator.

The present invention has been made by paying attention to this point, and in a musical performance device which is provided with a plurality of musical performance speakers and outputs a musical performance sound by using all of the speakers, some of the speakers are replaced by other speakers. It is an object of the present invention to provide a performance device that can easily and accurately adjust the volume even when it is used for a special purpose, especially an application involving volume adjustment.

[0006]

In order to achieve the above object, the performance apparatus according to claim 1 is a performance apparatus provided with a plurality of performance speakers for outputting a performance sound, and the user performs the plurality of performances. Volume operator for adjusting the volume of the sound output from the speaker for performance, a first mode in which sound is output from only a predetermined partial speaker of the plurality of performance speakers, and the plurality of performance speakers Switching means for selectively switching the second mode in which sounds are output from all of the above, and when the first mode is selected by the switching means when the user operates the volume operation element, When the sound volume output from the predetermined partial speaker is not controlled according to the operation amount, and the second mode is selected by the switching unit, The sound output from all of the performance speaker including the predetermined portion speaker, and having a control means for volume control in accordance with the operation amount.

[0007] Preferably, the apparatus further comprises sound collecting means for collecting ambient sounds, and the first mode is a calibration mode, and in the calibration mode, a predetermined volume is output from the predetermined partial speaker. A test sound is output, a reflected sound corresponding to the test sound is collected by the sound collecting means, and ambient acoustic characteristics are measured based on the collected sound (claim 2).

Further, preferably, the second mode is a performance mode, and in the performance mode, the sound characteristic of the performance sound is changed based on the acoustic characteristic measured in the first mode, The performance sound whose characteristics are changed is output from at least a part of the plurality of performance speakers (claim 3).

Based on performance information input from the operator 6 or preset performance information Sound source circuit 14 for generating a signal,
An effect circuit 15 for giving various effects to the tone signal from the tone generator circuit 14, a front speaker volume 17 and a rear speaker volume 16 for adjusting the signal level of the tone signal from the effect circuit 15, and a volume It is composed of left / right front speakers 18a, 18b and left / right rear speakers 18c, 18d which convert the tone signals from 16 and 17 into sound.

The above components 4 to 16 are connected to each other via a bus 19, a timer 11 is connected to the CPU 8, an effect circuit 15 is connected to the tone generator circuit 14, and a volume 16 and an effect circuit 15 are connected to the effect circuit 15. 17 is connected, and speakers 18a,
18b, 18c and 18d are connected.

In the present embodiment, the effect circuit 15 has a DA
C (Digital-to-Analog Converter) is included, and the effect circuit 15 adds an effect to the digital sound data output from the sound source circuit 14 based on the parameter set by the CPU 8, and then converts it into an analog signal. And outputs it to the volumes 16 and 17 in the subsequent stage.

The rear speaker volume 16 is a CPU
It is a so-called digital volume that outputs a signal (tone signal) of a level corresponding to the value set by 8 to the left / right rear speakers 18c and 18d in the subsequent stage. On the other hand, the front speaker volume 17 is a normal analog volume whose output level (tone signal level) is directly adjusted by the analog volume operator 1.

The control processing executed by the musical performance apparatus constructed as described above will first be outlined, and then will be described in detail with reference to FIGS. 2 and 3.

The playing device of the present embodiment mainly has two kinds of modes, that is, a calibration mode and a playing mode. In each mode, the following control processing is performed. That is, (1) Calibration mode The playing device of the present embodiment measures the acoustic characteristics of the surroundings,
An effect parameter is set in the effect circuit 15 in accordance with the measurement result, and a user's favorite effect for the performance sound (for example, an effect similar to the performance sound when playing in a concert hall, a movie, etc. It is configured so that you can add sound effects when you watch a movie in the museum. In the calibration mode, this acoustic characteristic measurement to parameter setting are performed. As mentioned above, the acoustic characteristics are usually measured by outputting a test sound such as white noise or pink noise at a predetermined level (volume) and collecting and analyzing this reflected sound. In the embodiment, a plurality of chords are sequentially output from the left / right rear speakers 18c and 18d at a predetermined volume, and the reflected sounds are collected by the microphones 2 and 3 and analyzed. Therefore, in calibration mode,
The CPU 8 sets a value that provides a predetermined volume in the rear speaker volume 16, and even if the analog volume manipulator 1 is operated and the operation amount is detected by the operation amount detection circuit 4 at that time, the operation amount is detected. The processing according to the operation amount is not performed. (2) Performance mode Performance mode means that when performance is performed using the performance operator 6,
In this mode, the performance sound is output from all the speakers 18a to 18d. In the performance mode, when the analog volume operator 1 is operated, the value set in the rear speaker volume 16 is changed in association with the operation. In addition, front speaker volume 17
As described above, since the output level thereof is directly adjusted by the analog volume manipulator 1, the operation of the analog volume manipulator 1 is interlocked not only in the performance mode but also in the calibration mode. , Its output level is changed. Further, in the performance mode, an effect corresponding to the effect parameter set in the calibration mode can be added to the performance sound, and can be generated from some speakers, specifically, the left / right rear speakers 18c and 18d. Note that the performance sound to which the effect is added is not limited to a part of the speakers and may be generated from all the speakers 18a to 18d.

Next, this control process will be described in detail.

FIG. 2 shows a musical instrument according to the present embodiment, particularly C
It is a flow chart which shows the procedure of the main routine which PU8 performs.

In the figure, first, initialization processing such as clearing the RAM 7 and setting various parameter values to default values is executed (step S1).

Next, in accordance with the operation of the panel operator 7, a panel setting processing subroutine for performing various settings of this apparatus and various processing of performance data (the details will be described later with reference to FIG. 3). Execute) (Step S
2) Generate various parameters based on the event generated by the performance information input from the performance operator 6, output the generated various parameters to the tone generator circuit 14, and sound the tone generator circuit 14. The corresponding tone signal is generated from the tone generator circuit 14 by giving an instruction, and the effect circuit 15 is given an instruction to give an effect selected by the user, thereby giving the effect to the musical tone signal, After performing performance processing for outputting to the volumes 16 and 17 to generate musical tones from the speakers 18a to 18d (step S3), the step S3 is performed.
Returning to 2, the above processing is repeated.

FIG. 3 is a flow chart showing the detailed procedure of the panel setting processing subroutine.

In the figure, when the panel operator 7 is operated and the operation instruction is an instruction for environment setting, first,
A menu for detecting the type of environment-friendly effect or room acoustic environment that can be selected is displayed (steps S11 → S12 → S1).
3) Next, the type selected by the user from the displayed menu and the instruction to start the execution are accepted (step S14). Here, a part of the displayed menu contents is as follows. In other words, type 1: The one that only detects and records the room acoustic environment so that it can be used later when the environment-friendly effect is set (calibration only) Type 2: The acoustic characteristics specified by the user are reproduced. To detect the acoustic environment of the room, the detection result is recorded, and the detection result is used to determine the effect parameter for reproducing the acoustic characteristic specified by the user. What is set in the circuit 15 (calibration execution + effect parameter determination + effect circuit 15)
Effect parameter setting for type 3): To reproduce the acoustic characteristics specified by the user, a provisional room acoustic environment (for example, calibration results obtained in the past, recorded detection results, and installation of a musical instrument) By assuming the place as a living room of a general household, the default one is used, and the effect parameters for reproducing the acoustic characteristics specified by the user in the room environment are determined,
This effect parameter is set in the effect circuit 15 (non-calibration (reading of temporary room acoustic environment) +
Determination of effect parameter + setting of effect parameter to effect circuit 15) and the like.

In order to realize the environment-friendly effect designated by the user, it is optimal to consider the acoustic characteristics of the room in which the musical performance device is installed, and for that purpose, it is necessary to select the type of calibration. Ideally,
Since it takes time to measure the room acoustic environment, the performance device of the present embodiment can select a type for which calibration is not performed.

As described above, in the present embodiment, whether or not the calibration mode is selected is determined for each type, and the calibration mode is automatically set according to the selected type. It is configured.
Of course, the present invention is not limited to this, and the user may select the calibration mode.

When the calibration mode is selected, the rear speaker volume 16 is set to a value such that a test sound of a predetermined level is output from the rear speaker volume 16, and the pitch is set at the predetermined level. Is executed while changing the value of, ie, a plurality of chords are sequentially sounded at a predetermined level (steps S15 → S16).

Subsequently, as a result of the pronunciation, the reflected sound reflected from the obstacles such as the surrounding walls is collected by the microphones 2 and 3, and the collected sound is analyzed, whereby the present playing device is produced. The acoustic characteristics of the place where is placed are analyzed (step S17), and the processes of steps S16 and S17 are continued until the analysis is completed.

When the analysis of the acoustic characteristics is completed, the parameters of the effect circuit 15 are calculated so as to obtain the type selected by the user in consideration of the analysis result, and then the RAM is stored.
The data is temporarily stored in the parameter storage area secured at the predetermined position 10 (step S19).

Then, the parameters stored in the parameter storage area are set in the effect circuit 15 (step S2).
0), the analysis result and the parameter value set in the effect circuit 15 are stored in, for example, the external storage device 13 (step S21), and then the performance mode is entered (step S22).

In step S15, if the calibration mode is not selected, the parameter values set by default according to the selected type, or the acoustic characteristics previously analyzed and stored parameters are stored. After storing the value in the parameter storage area, the process proceeds to step S20 and the processes of steps S20 to S22 are performed.

When the calibration mode is not selected when the analog volume manipulator 1 is operated, that is, when the performance mode is selected, the operation amount of the analog volume manipulator 1 is linked. Then, the set value for the rear speaker volume 16 is changed (steps S23 → S24 → S25). On the other hand, at this time, if the calibration mode is selected, the panel setting process is terminated without doing anything.

Furthermore, when an instruction other than the environment setting instruction and the operation of the analog volume operator 1 is given, the processing according to the instruction is performed (step S26).

As described above, in the present embodiment, when the calibration mode is selected, the rear speaker volume 16 is set to a predetermined value, and even if the analog volume operator 1 is operated at this time. Since the setting value of the rear speaker volume 16 is not changed in conjunction with the operation, the calibration can be accurately performed without performing the troublesome volume control.

In the present embodiment, the test sound is output to the left / right rear speaker 18 in the calibration mode.
Although it is generated from c and 18d, it is not limited to this.
It may be generated from the left / right front speakers 18a and 18b. If the accuracy of the calibration is not a problem, the test sound may be generated from only one of the speakers. Of course, the total number of speakers is not limited to four, and may be more or less than this. However, if the number is one, it deviates from the gist of the present invention, so it is necessary to provide at least two or more.

Further, in the present embodiment, a digital volume is adopted as the volume for determining the volume of the speaker used for the calibration, that is, the rear speaker volume 16, but the present invention is not limited to this, and its output level is set by the CPU 8. If possible, an analog volume may be used.

Further, in the present embodiment, some of the speakers 18a to 18d are speakers 18c and 18d.
Was used as a calibration application as well as a performance sound output application, but the calibration application is only an example of other special applications. May be adopted.
