Description
Technical field
The utility model belongs to buzzer assembling fittings applied technical field, and in particular to metal waterproof buzzer it is stainless
Outer steel shell, it is adaptable to the protection of safety is carried out to the buzzer after assembling and the convenient, sealing of assembling is excellent.
Background technology
Buzzer is a kind of electronics buzzer of integral structure, using DC-voltage supply, be widely used in computer,
Make acoustical generator in the electronic products such as printer, duplicator, alarm, electronic toy, vehicle electronics, telephone set, timer
Part.Buzzer is broadly divided into piezo buzzer and electromagnetic buzzer two types.Buzzer in circuit with alphabetical " H " or
“HA”（Old plant " FM ", " ZZG ", " LB ", " JD " etc.）Represent.
It is divided into according to operation principle, one, voltage-type buzzer, piezo buzzer is mainly by multivibrator, piezoelectricity honeybee
Ring the composition such as piece, impedance matching box and resonant tank, shell.Light emitting diode is also equipped with some piezo buzzer shells, it is many
Harmonic oscillator is made up of transistor or integrated circuit, after switching on power（1.5 ~ 15V direct-current working volts）, multivibrator
Shake, export 1.5 ~ 2.5kHZ audio signal, impedance matching box promotes piezoelectricity singing piece sounding, and piezoelectricity singing piece is by lead zirconate titanate
Or lead magnesio-niobate piezoceramic material is made, silver electrode is plated on the two sides of potsherd, through polarization and burin-in process after, then with Huang
Copper sheet or stainless steel substrates stick together；2nd, electromagnetic buzzer, electromagnetic buzzer by oscillator, magnet coil, magnet, shake
Dynamic diaphragm and shell etc. are constituted, after switching on power, and the voice-frequency signalling current that oscillator is produced makes magnet coil by magnet coil
Produce magnetic field.Vibrating diaphragm is under the interaction of magnet coil and magnet, periodically vibration sounding.
Buzzer drive circuit, because the operating current of buzzer is general than larger, so that the I/O mouths of single-chip microcomputer are
It can not directly drive（But AVR can drive small-power buzzer）, so to be driven using amplifying circuit, typically using three
Pole pipe amplifies electric current, and buzzer drive circuit typically all includes following components：One triode, buzzer, one
Individual fly-wheel diode and a power filtering capacitor, 1, buzzer, sounding component applies DC voltage at its two ends（Active honeybee
Ring device）Or square wave（Passive buzzer）Just can be with sounding, its major parameter is appearance and size, voice directions, operating voltage, work
Working frequency, operating current, type of drive（Direct current/square wave）Deng these can be selected as needed；2nd, fly-wheel diode,
Buzzer is substantially an inductive element, and its electric current is unable to transition, it is therefore necessary to have a fly-wheel diode to provide afterflow, no
Then, tens volts of peak voltage can be produced at buzzer two ends, driving triode may be damaged, and disturb whole circuit system
Other parts；3rd, filter capacitor, filter capacitor C1 effect is filtering, filters out influence of the buzzer electric current to other parts,
The AC impedance of power supply can be improved, if it is possible, being preferably again one 220uF of parallel connection electrochemical capacitor；4th, triode, triode
Q1 plays on-off action, and the high level of its base stage makes triode saturation conduction, makes buzzer sounding, and base stage low level then makes three poles
Pipe is closed, and buzzer stops sounding.
By above-mentioned, buzzer its be small-sized circuit structure, it is necessary to be carried out to the electronic unit of mounted inside close
The protection of envelope, safety, so requiring that the package shell of buzzer higher it is necessary to have stronger toughness, long lifespan and will be just
In accurately being assembled, while needing to ensure the stabilization of overall structure i.e. without displacement or cap and showing that shell bottom comes off after assembling
As.But, the metal shell assembled for buzzer of existing traditional structural design production, its complicated, installing/dismounting makes
With not convenient, while, easily there is irrational design after deformation, the phenomenon of fracture, and assembling and leads in its poor toughness after long-term use
Inside is caused the phenomenon of displacement occur（Cap, shell bottom）, damage is caused to internal circuit configuration, it is impossible to make timely, accurately pre-
It is alert etc., it can not meet the assembling use demand of existing buzzer, and this is current urgently to be resolved hurrily.
Therefore, based on above mentioned problem, the utility model provides metal waterproof buzzer stainless steel casing.
