One path of output of the tempo counter going through the ring trigger and the output of the tempo sound trigger are both amplified and sent out through a speaker, and the other path of output of the tempo counter is sent to the heavy tempo light display. The output of the ring vibrator is connected with the ring trigger. The utility model has the advantages of compact circuit, complete functions and convenient fabrication, has the basic functions of a metronome, acoustic-optic synchronous display or only light display and the attached A<4> tone, and is easily made into a product.
Description
The utility model relates to a kind of metronome of answering electricity consumption or electrical resonator.
Metronome has been widely used in fields such as music teaching as producing the acoustics utensil of beat as the time interval in advance of timing standard.
Classic mechanical type metronome is according to pendulum theory, changes the position of weight on fork and sets up the bat frequency, and its beat is set to 0,2,3,4,6.Weigh, pat by the tinkle of bells and the expression of " clatter " sound.Usually fully-wound can only be worked about 15 minutes, and volume is bigger.
The Dm-20 numeral metronome that NSK (SEIKO CORPORATION) is produced is liquid crystal display, and its circuit structure system adopts special-purpose miniature components and parts, and cost is higher, function singleness, quiet single ground, its beat flashes expression by the point-like liquid crystal, do not have branch light, that retake, light is difficult for seeing when dark don't.
" integrated circuit is used 350 examples " (Electronic Industry Press, 1988-02) Sheffer stroke gate of introducing is formed the acousto-optic metronome, Sheffer stroke gate is formed miniature electric qin circuit and metronome circuit and " electronic circuit collection four " (People's Telecon Publishing House, 1987-02) its function singleness of click metronome of Jie Shaoing does not possess the condition of commercialization.
The electronic metronome that " e-life " (daily magazine, 1991.8) are introduced has advanced circuit design, but still the function of weight metronome is only arranged.
The purpose of this utility model aims to provide a kind of practical multifunction electronic metronome.
The utility model comprises beat oscillator, beat count device, optical display unit, trigger, note amplifier, sound equipment and power supply.Also be provided with the tinkle of bells oscillator; Optical display unit is established retake optical display unit and beat optical display unit; Trigger is established the tinkle of bells trigger and metronome trigger.
The output of beat oscillator is connected with beat count device, metronome trigger and beat optical display unit respectively.The output one tunnel of beat count device is imported note amplifier again through the tinkle of bells trigger and with the output of metronome trigger behind function switch, at last by loudspeaker or/and the earphone sounding; Another road output of beat count device is connected with the optical display unit of retaking; The beat count device is established the beat change-over switch in addition.
The output of the tinkle of bells oscillator connects the tinkle of bells trigger.
Also be provided with A
4Tone alternator, its output send audio amplifier behind function switch.
The utility model and existing electronic metronome relatively, it is succinct to have a circuit, function is many, adopts universal components and parts, manufacture craft is simple, cost is low, is easy to advantages such as commercialization.The light emitting diode that can adopt 2 different colours is respectively as retaking and bat (patting) optical display unit, also can send the expression of " stining " and " clatter " sound with phototiming weighs, pats, can not sound yet, only use up demonstration expression beat, perhaps substitute loudspeaker for individual audition with earphone.Its bat frequency can be regulated intuitive and convenient continuously by knob.Owing to the mute function of only using up demonstration is arranged, so range of application is wider, for example carries out beat speed rule training and testing etc.Except that having metronomic basic function and acousto-optic synchronously or only the lightshow function, because subsidiary A
4Therefore tone alternator can be used as the benchmark of musical instrument tuning.Simultaneously, the utility model power consumptive province can be used for a long time with dry cell, and volume is less, and is easy to carry.
Fig. 1 is a theory diagram of the present utility model.
Fig. 2 is circuit theory diagrams of the present utility model.
Below with reference to drawings and Examples the utility model is described in detail.
Embodiment: as shown in Figure 1, the utility model comprises beat oscillator (1), beat count device (2), the tinkle of bells and A
