Abstract

PURPOSE:To vary the scale of a sound to be generated in real time by providing a timbre converting means which operates in synchronism with a switch and a control means which varies the scale according to the state of a switch means. CONSTITUTION:The switch 5 which can be operated from the outside and a scale converting device 6 which operates in synchronism with the switch 5 are fitted and this external switch 5 is operated to control the scale converting device 6, which processes a sound signal sent from an internal processor 7 to vary the scale of the sound generated by a speaker 8 in real time. Consequently, when the external switch 5 is operated manually, the scale of the sound generated by the speaker 8 can be varied instantaneously in real time.

(Prior Art) Until now, none of the electronic devices, such as word processors and personal computers, had a hardware configuration that allowed the scale of the sound generated from internal speakers to be changed externally. For this purpose, a software program was used to change the scale of the sound, and by running the program, the operation of the internal processing device was controlled.
With this, when changing the scale of a sound, a software program must be executed, making it difficult to realize real-time processing. [Problems to be Solved by the Invention] As described above, conventional electronic equipment uses a software program to change the scale of the sound generated from the speaker, and therefore has the following drawbacks. In other words, when changing the scale, a software program must be executed in advance to control the internal processing device.
Therefore, it was not possible to change the scale of the speaker sound in real time.

An object of the present invention is to solve the above problems and provide an electronic device that can change the scale of the generated sound in real time. (Means to solve problems (
In the present invention, a switch that can be operated from the outside and a scale conversion device that operates in synchronization with the switch are installed, and by operating this external switch, the scale conversion device is controlled and the data sent from the internal processing device is By processing the coming sound signal, it is now possible to change the scale of the sound emitted from the speaker in real time. (Function) In the present invention, diagnosis is made by manually operating an external switch to instantly change the scale of the sound generated from the speaker in real time.

FIG. 2 shows a button type switch which is an example of the embodiment shown in FIG. 1. Figure 3 is a block diagram of the system configuration, in which 5 is a keyboard, 6 is a scale conversion device, 7 is an internal processing device, and 8 is a speaker. FIG. 4 is a flowchart showing the flow of the process shown in FIG. 3, and (S1) to (S4) represent each step of the process. The flow of scale conversion processing will be explained using FIG. Fourth
At step (S1) in the figure, the internal processing device outputs a signal to generate sound from the speakers in response to a request from the keyboard 5. In step (S2), the voice conversion device receives the signal from the processing device and converts the scale according to the state of the key switches on the keyboard. At this time, the voice conversion device and the key switch are connected by hardware, so that the switch status is reflected in the voice conversion device in real time. Next, in step (S3), the audio conversion device outputs the scale-converted signal to the speaker. In step (S4), the speaker receives the signal and generates sound.
