Description

[Detailed description of the invention] <Industrial application field> The present invention relates to electronic equipment such as audio equipment.

<Conventional technology> In audio equipment, etc., the rotational movement of a volume switch is converted into a pulse signal, the direction and amount of rotation are detected, and the volume can be increased/decreased, fader balance controlled, or bass/treble controlled. Configurations that do this are known.

<Problems to be Solved by the Invention> A switch that converts such a rotational operation into a pulse signal is structurally designed to allow unlimited rotational operations. Therefore, it is possible to perform rotation operations that exceed the upper and lower limits of the control range of volume, fader, balance, bass/treble, etc., which has the disadvantage of forcing the user to perform unnecessary operations, and also has the disadvantage of forcing the user to perform unnecessary operations. There was an issue where it was unclear whether the target had been reached or not. Furthermore, such a switch cannot have a positioning structure that temporarily stops the switch at an intermediate point in the operation to produce a click feeling, so that it is difficult to perform operations such as adjusting the switch to the center position.

Means for Solving the Problems> The present invention has been made to solve the above-mentioned conventional problems, and includes an operating means that can rotate without limit, and a rotating member that detects the direction of rotation of the operating means. direction detection means, rotation amount detection means for detecting the amount of rotation of the operating means, and sound control means for controlling the adjustment amount of the sound output adjustment means in accordance with the outputs of the rotation direction detection means and the rotation amount detection means. The basic feature is that the rotation direction detecting means and the notification means output a notification at a predetermined rotation point according to the outputs of the rotation direction detection means and the rotation amount detection means.

Further, adjustment position detection means for detecting the adjustment position of the sound adjustment means is provided, and the rotation direction detection means and the eye movement amount detection 11
Instead of the notification means that outputs a notification at a predetermined rotation point according to the output of the ♂ means, it may be provided with a notification means that outputs a notification at a predetermined adjustment position according to the detection output of the adjustment position detection means. good.

Function> The amount and direction of rotation of the operating means are detected by the rotation direction detection means and the rotation amount detection means, and the adjustment amount of the sound output adjustment means is controlled in accordance with the detected output.

Further, the notification output is executed by the notification means at a predetermined rotation point in accordance with the detection output. Thereby, a notification is made when the upper limit or lower limit of the adjustment amount of the sound adjustment means is exceeded. Furthermore, if the predetermined rotation point for adjustment is set to a point corresponding to the center position, notification will be made at the center position.

Further, when an adjustment position detection means for detecting the adjustment position of the sound adjustment means is provided, and a notification means for outputting a notification at a predetermined adjustment position according to the detection output of the adjustment position detection means is provided, a predetermined Notification is performed at the adjusted position.

<Example> An embodiment of the present invention will be described below based on the drawings.

In FIG. 1, normal rotation and reverse rotation pulses are input to a control device 2 by operating a pulse switch 1.

Here, the direction and amount of rotation of the pulse switch 1 are detected. The pulse switch also serves as an operating device for volume, fader, balance, bass, and treble, and the selection key 9 is configured to select the functions.

The control device 2 controls the electronic volume device 3, balance adjustment device 4, fader adjustment device 5, bass adjustment device 6, and treble adjustment device 7 of the audio circuit X according to the rotation direction and amount of rotation of the pulse switch 1. It is configured to cause the audio circuit X to perform volume, fader, balance, bass, and treble operations.

A predetermined rotation point on the pulse switch is also preset in the control device 2, and it is detected that the pulse switch 1 has reached the predetermined rotation point based on the rotation direction and rotation amount input from the pulse switch 1. At times, the device is configured to send a signal to the buzzer device 8 to generate a buzzer sound. The predetermined rotation points may be set individually for volume, fader, balance, bass, and treble, or may be the same. This predetermined rotation point is the center position of operation or the upper limit I'7t? ! It can be i or the lower limit; d, etc. In this embodiment, three predetermined rotation points are set: the upper limit, the lower limit, and the center position, but the present invention is not limited to this, and only the upper and lower limits may be used.
Alternatively, any setting can be made, such as setting only the center position.

The operation when selecting the electronic volume device 3 using the selection key 9 and adjusting the volume by rotating the pulse switch 1 will be described with reference to FIG.

The control device 2 determines the direction of rotation when the Epulse is manually operated from the pulse switch (Step 20), and in the case of clockwise rotation, increases the volume data by +1 (Step 21).
In case of counterclockwise direction, set the volume data to -1 (
Step 22). Then, it is determined whether the operating range of the electronic volume device 3 exceeds the upper or lower limit based on the pulse (step 23.24), and if it does, a signal is sent to the buzzer device 8 to sound the buzzer (step 25.26). If not, the volume data incremented by +1 or -1 is stored (step 27). Then, it is determined whether or not the pulse has reached the midpoint of the operating range of the electronic volume device 3 (step 28), and if it has reached the midpoint, the buzzer device 8
The volume data is transferred to the electronic volume device 3 to increase or decrease the volume (step 30). If the intermediate point is not found in step 28, the process jumps directly to step 30.

In the above embodiment, the rotation point of the pulse switch 1 is detected and notified, but a device for detecting the adjustment positions of the volume, fader, balance, bass, treble, etc. It is also possible to configure so that notification is performed at a predetermined adjustment position by output.
