Abstract

Abstract A music tuner having both a contact sensing device and a non-contact sensing device to pick up the sound from a music instrument is so designed that it can automatically or manually select one of the sensing devices that is most suitable to the situation where the music tuner is used. The display screen of the music tuner is freely rotatable and pivotable, thereby allowing optimum view angle wherever the music tuner is placed. The display screen is configured to graphically represent the tune of the music instrument so that the user can easily and intuitively grasp the pitch of the sound as compared with a standard pitch. The music tuner is able to display the result by a normal display mode, a mirror display mode, or a combination of both modes.

A music tuner for tuning a music instrument, comprising: a tuner body having a display screen to show a pitch of a sound from the music instrument and a difference from a target sound; a non-contact sensing device that senses sounds from said music instrument through the air, said non-contact sensing device being a microphone; a contact sensing device that senses sounds from the music instrument by physically contacting with the music instrument, said contact sensing device being a piezoelectric device; an attachment clip for attaching the music tuner to an object including the music instrument; and a circuitry to select either said non-contact sensing device or said contact sensing device for processing the sounds from the music instrument; wherein said non-contact sensing device is mounted on the tuner body and said contact sensing device is mounted on the attachment clip, and wherein said tuner body is detachably connected to the attachment clip, thereby establishing the music tuner having both said non-contact sensing device and said contact sensing device one of which is automatically selected when tuning the music instrument.
Claim 3
Dependent Claim 43 words
A music tuner for tuning a music instrument as defined in claim 1 , wherein said circuitry automatically selects either said non-contact sensing device or said contact sensing device by comparing an output level of the sensing device with a predetermined threshold level.
Claim 4
Dependent Claim 42 words
A music tuner for tuning a music instrument as defined in claim 1 , wherein said circuitry selects either said non-contact sensing device or said contact sensing device in response to a manual operation of a switch provided on the music tuner.
Claim 5
Dependent Claim 43 words
A music tuner for tuning a music instrument as defined in claim 1 , wherein said attachment clip having said contact sensing device is detachable from said tuner body to allow said music tuner to function separately and independently from said attachment clip.
Claim 6
Dependent Claim 46 words
A music tuner for tuning a music instrument as defined in claim 2 , wherein said circuitry selects the contact sensing device for picking the sound of the music instrument when an output level of said contact sensing device is larger than the predetermined threshold level.
Claim 7
Dependent Claim 85 words
A music tuner for tuning a music instrument as defined in claim 2 , wherein said circuitry selects the contact sensing device for picking the sound of the music instrument when an output level of said contact sensing device is larger than the predetermined threshold level, and wherein said circuitry determines whether a predetermined time has passed after the output level of said contact sensing device fell below said predetermined threshold level and selects said non-contact sensing device only if said predetermined time has passed.
Claim 8
Dependent Claim 64 words
A music tuner for tuning a music instrument as defined in claim 1 , wherein said circuitry collects time period data of the sound of the music instrument detected by said sensing device, determines a fundamental frequency of the sound based on the collected time period data, and causes to display a difference between the fundamental frequency of the sound and a target sound.
Claim 9
Dependent Claim 53 words
A music tuner for tuning a music instrument as defined in claim 1 , wherein said tuner body is attached to said attachment clip in a manner rotatable in clockwise and counterclockwise directions, and wherein said tuner body is attached to said attachment clip in a manner pivotable in backward and forward directions.
Claim 10
Dependent Claim 106 words
A music tuner for tuning a music instrument as defined in claim 1 , wherein said display screen displays a measured result of the sound from the music instrument either by a normal display mode or a mirror display mode, wherein a lower frequency is displayed at a left side of the display screen and a higher frequency is displayed at a right side of the display screen in said normal display mode, while the lower frequency is displayed at the right side of the display screen and the higher frequency is displayed at the left side of the display screen in said mirror display mode.
Claim 11
Dependent Claim 44 words
