There are two groups of tab members, and the resigning portion stepped down for tab member be additionally provided with coil, so in spot welding wire, it is only necessary to
Assist side just carries out spot welding in face of wire, and production can be made more simple, convenient, it is possible to achieve automated production.
Installation process is said below：
Contact pin is directly inserted into installation pcb board during buzzer during installation, and the plug on upper inserts is in top, lower inserts bottom
Elastic card claw deform upon and snap on installation pcb board, plug is down pushed away the elastic card claw for pinning lower inserts bottom, makes it not
It can deform upon, and then be fixedly mounted on pcb board；As long as shifting plug onto top during dismounting, elastic card claw can occurs
Deformation, withdrawn from pcb board.
The upper and lower inserts is cylinder., can be with the upper and lower shell of cylinder because upper and lower inserts is using cylinder
Body is more bonded, and is installed when mounted also more firm.
The upper inserts bottom is provided with first annular flange 17 close to the inner side of upper jack, inserts bottom is inserted away from upper
The outside in hole forms neck 18；The lower outside of the inserts top away from lower jack is provided with the second annular being used cooperatively with neck
Flange 19.Pass through being used cooperatively for neck and the second annular flange so that lower inserts is inserted into inserts, so as to realize
The pre-determined bit of upper and lower casing and installation.
Second annular flange is interference fitted with neck.Due to using interference fit so that the peace between upper and lower casing
Dress is more firm.
The stage portion downside is provided with annular groove 20；The lower house top surface is provided with what is be used cooperatively with annular groove
3rd annular flange 21.Pass through the cooperation of annular groove and the 3rd annular flange so that upper and lower casing installation is more convenient.
The bayonet unit includes the edge clipping 22 for protruding from upper casing body side surface, and edge clipping center is provided with neck 23；Under described
Hull outside face is provided with the buckle 24 that can be inserted into neck.By the way that buckle is inserted into neck, on the one hand due in neck and second
Annular flange together in the presence of cause upper and lower casing connection it is more firm, on the other hand dismount more convenient；And due to upper casing
Body and lower house using neck and snap connection, and this structure can directly seal fixation, it is not necessary to which epoxy sealing, this is also considerably reduced
Production process and production cycle, greatly save cost.
The bayonet unit includes the deep-slotted chip breaker 26 for being arranged on upper shell bottom surface, and the arc slot cross-section is " T " shape, lower house
Top surface is provided with the slot connected with deep-slotted chip breaker, and the inserted link 27 in pluggable slot and deep-slotted chip breaker；Inserted link top both sides
If flexible triangle claw 28, inserted link bottom is provided with limited cover；The lower house bottom surface is provided with stopper slot, 30 liang of limited cover
Side is provided with the gag lever post 29 that can be inserted into stopper slot, and the gag lever post on the outside of limited cover, which is provided with, can be caught in through hole in stopper slot side wall
Spring card bead.Deep-slotted chip breaker will be inserted by inserted link, because the top both sides of inserted link set flexible triangle claw, to realize
The connection of upper and lower casing；The limited cover set by inserted link bottom avoids inserted link from rotating；By spring card bead to realize pair
The fixation of the position of limited cover；Inserted link is rotated after taking off limited cover, the triangle claw of inserted link both sides is no longer connected to arc
On the both sides at groove top end；Using this buckle structure, it is not necessary to set protuberance on upper casing outside so that profile
It is more attractive, and service life is longer.
The quality piece thickness is 0.16-0.20mm.Quality piece thickness uses 0.16-0.20mm, can greatly improve honeybee
The acoustic pressure for device entirety of ringing.
The quality piece thickness is 0.18mm.When quality piece thickness uses 0.18mm, buzzer can be most greatly improved
Overall acoustic pressure.
Gap 25 between the vibrating diaphragm piece and iron core is 0.36-0.38mm；The high 5.8-6.8mm of cavity.So that honeybee
Ring the whole magnetic energy of device concentrate on vibrating diaphragm piece, coordinate larger inner-cavity structure so that buzzer have wider frequency band and
Higher acoustic pressure；So that buzzer not only has very wide frequency band, higher acoustic pressure in low frequency part；It is particularly bright in HFS
Aobvious, frequency range is in 1400Hz~2600Hz, and acoustic pressure is in more than 95db.
A kind of production method of no-welding high frequency high sound pressure buzzer, it is characterised in that comprise the following steps：Step 1：Around
Line, coiling is carried out to iron core and forms coil；Step 2：Frock is covered, lower house is placed in circulation frock；Step 3：Tree lace road
Wiring board on plate, wiring board is arranged in lower house after gluing on lower house with point gum machine；Step 4：Tree lace circle coil,
With point gum machine, gluing is gluing in the circuit board by the coil in step 1 in the circuit board；Step 5：Microdot is welded, and traverse point is welded in
On the weld part of wiring board；Step 6：Polarity is surveyed, detects the polarity of lead electrode；Step 7：Glue magnet ring upper magnetic ring, on iron core
One layer of glue is played in face, and magnet ring is bonded on iron core；Step 8：Box is arranged, lower house enters next road work after being placed into turnover box
Sequence；Step 9：Glue curing；Step 10：Turn magnetic, lower house is carried out to turn magnetic；Step 11：Clear magnetic, clear magnetic is carried out to lower house；
Step 12：Gap is measured, the distance of diaphragm step is placed on measurement iron core top to magnet ring；Step 13：Assembling, by upper and lower casing
When being assemblied together, and diaphragm and quality piece is spot-welded together；Step 14：Test, resistance, the sound of product after detection assembling
Pressure, electric current；Step 15：Complete assembling.At present in spot welding wire, because solder joint sets the assist side back side, assembled
When need to turn wiring board and could carry out spot welding, this process needs repeatedly to change frock, greatly reduces production effect
Rate, and weld part has been reserved there is provided tab member because assist side is positive in the utility model, therefore only need in circuit
Plate just carries out spot welding in face of wire, and so whole circulation process only needs to complete life using frock can in step 2
Production, greatly reduce the number of set frock, substantially reduce technological process；Installation additionally, due to upper and lower casing in the application is adopted
With using neck and snapping connection, this structure can directly seal fixation, it is not necessary to which epoxy sealing, this is also considerably reduced production process
And the production cycle, greatly save cost.
It is described above, only it is preferred embodiment of the present utility model, any formal limit is not done to the utility model
System, it is every according to any simple modification made in the technical essence of the utility model to above example, equivalent variations, fall
Enter within the scope of protection of the utility model.
