Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tuning status display device for displaying the tuning status of a stringed instrument or the like.

[0002]

2. Description of the Related Art As a conventional tuning status display device, an actual performance sound is input and the tuning status is displayed based on the pitch information (Japanese Patent Publication No. 4-39022), or the measured value is logarithmically converted. Displaying the amount of deviation with respect to the reference value by outputting (Japanese Patent Application Laid-Open No. 57-190233)
Etc. have been proposed.

[0003]

However, since such a conventional tuning state display device is constructed as a single device, when used for tuning a stringed instrument, for example, the positional relationship with the string and the measurement are performed. Depending on the environment, ambient noise is mixed in and accurate pitch information and measured values cannot be obtained. As a result, even if the tuning state is displayed with this pitch information as a reference, or the measured value is logarithmically converted and the deviation amount from the reference value is displayed, the displayed value has an error due to the presence of the ambient noise. However, it was not possible to accurately display the tuning state.

The present invention has been made in view of such conventional problems, and an object thereof is to provide a tuning state display device for accurately detecting and displaying the tuning state of a musical instrument.

[0005]

In order to solve the above problems, according to the present invention, tuning sound collecting means is provided on the side of the wristwatch body, and the tuning sound collecting means is provided on the surface of the timepiece body. A display unit is provided for displaying the tuning state based on the sound picked up by.

[0006]

In the above structure, when displaying the tuning state of the guitar, for example, the wristwatch main body is attached to the arm of the plucked string. Then, when the display portion is turned up after the string is struck, the tuning sound collecting means provided on the side portion of the wristwatch body faces the string direction. Therefore, the sound collecting means for tuning that is oriented in the string direction can reliably collect the sound generated by the vibration of the string. Further, since the tuning state based on the collected sound is displayed on the display unit facing upward, the tuning state can be confirmed by visually observing the display unit from above.
