Abstract

The utility model relates to a mechanical metronome, comprising a pendulum, a bell mechanism, an escape wheel and an escape wheel component. The pendulum is fixed on a pendulum shaft and is linked with the pendulum shaft; the escape component is driven by the pendulum; the escape wheel is driven by the escape component; the bell mechanism comprises a bell and a bell hammer; one end of the bell hammer is provided with a clapper; the escape wheel is provided with a bell portion; when the bell portion passes through the clapper, the bell hammer slaps the bell; in a beat period, the number of the bell portions distributed on the rotation angle of the escape wheel are equal to the number of the non-powerful beats in the time period. In the non powerful beat in a beat, the clapper drives the bell hammer to slap the bell to give out the sound via the bell portion, the sound effect consistent with the beat showing sound of the sounder in the music practice is generated, which makes the user easily distinguish the powerful beat and the non powerful beat.

Description

The machinery metronome

[technical field]

The utility model is about a kind of metronome, especially a kind of mechanical metronome.

[background technology]

Existing metronome comprises pendulum and acoustic means, but the pendulum cycle send metronome, acoustic means can only send jingle bell sound by the rhythm of setting up (clapping as 3/4 or 2/4) in stress.Yet, there is following shortcoming in this kind design: sound frequency is low when showing that according to sound equipment in the music practice normal conditions of bat are strong beat, but not sound frequency height then during strong beat (weak beat or subsidiary strong beat), knock and show in bat sound and the dancing party music such as a wooden fish and a pair of hand-held bells played by striking together " rattle away and sting, rattle away and sting " " the sound of sth. throbbing or bursting crash crash, the sound of sth. throbbing or bursting crash crash " the percussion music combined sound of expression dance step beat.And the existing mechanical metronome adds the tinkle of bells when strong beat, what form " sting and rattle away, sting and rattle away " shows bat sound, then just in time opposite with situation in the music practice, the person obscures strong beat and non-strong beat easily thereby make the music learning, be unfavorable for classroom instruction, the exercise of qin room and music practice unify combine.

[utility model content]

The purpose of this utility model is to provide a kind of jingle bell sound that sends, the mechanical metronome of the tinkle of bells that do not make sound when strong beat when non-strong beat.

The purpose of this utility model is achieved in that this machinery metronome comprises pendulum, acoustic means, escape wheel and catch members, this pendulum be fixed on the balance staff and with its interlock, this pendulum and catch members interlock, this catch members and the interlock of this catch members wheel, acoustic means comprises jingle bell and bell clapper, this bell clapper one end is provided with clapper, described escape wheel is provided with jingle bell portion, when this jingle bell portion passes through clapper, then bell clapper knocks jingle bell, in cycle, the quantity of the jingle bell portion that distributes on the escape wheel anglec of rotation is the integral multiple of this beat non-strong beat quantity in the cycle at a beat.

In cycle, the quantity of the jingle bell portion that distributes on the escape wheel anglec of rotation equals the quantity of this beat non-strong beat in the cycle at a beat.

Compared with prior art, the utlity model has following advantage: when the non-strong beat of a beat in the cycle, clapper is by jingle bell portion, drive bell clapper and knock the jingle bell sounding, thereby produce not jingle bell of a kind of strong beat, non-strong beat jingle bell meet music practice, allow the user be easy to distinguish the mechanical metronome of strong beat and non-strong beat.
