Electric acoustic conversion toot plate altogether is loaded in in the various miniature electric machines such as portable beep-pager of card shape.Require miniaturization in this class electric acoustic machine, its component parts is emphasized the tendency of tinyization.
Figure 11 and Figure 12 represent to be used for an example of the electric acoustic converter in the past of peak toot device etc.Become the processing that individually is shaped of columnar upper casing 202 and lower casing 204 usefulness synthetic resin.At the back side of lower casing 204 yoke 206 and substrate 208 are housed on one side, these yokes 206 and substrate 208 usefulness binding agents are by integrated.Adorning magnetic core 210 to connect form in the central.At the coil 212 that is equipped with on the magnetic core 210 in advance above skeleton etc., around it, locate to be equipped with magnetite 214 circlewise.The lead-in wire 216,218 of coil 212 is drawn at the back side of substrate 208 on one side, receives on the electrode 220,222 on the substrate 208 with solder.With respect to vibrating body 224, yoke 206, magnetic core 210, and magnetite 214 constitute electromagnetism transform portions 226.
On the internal face of lower casing 204, be provided with the support step 228 of the edge indentation of ratio open.This supports being formed on of step 228 to cause the big part of diameter 230 on the opening portion.And vibrating body 224 is installed on the support step 228.Be equipped with in the heart in this vibration 224 to strengthening the discoid magnetic sheet 232 of one-tenth of oscillating mass.That is, vibrating body 224 is made of thin toot plate 231 altogether and magnetic sheet 232.
Embed the fitting portion 234 of upper casing 202 on the big part 230 of the diameter of lower casing 204, the engagement means of this lower casing 204 and upper casing 202 usefulness ultrasonic bonding etc. is bonded into one.And on the upper casing 202 and the vibration of vibrating body 224 altogether toot, for obtaining suitable sound press, formed toot space 236 altogether, simultaneously, outstanding on one side and be formed with the playback tube 240 of open-work 238 to toot space 236 altogether in its courtyard part.
, to such electric acoustic converter, influence such as the Performance And Reliability of the acoustic characteristic of the product confrontation electric acoustic converter of vibrating body 224 etc. is very big.Manufacture method about this vibrating body 224 now is described.As shown in figure 13, vibrating body 224 usefulness spot welding machines 242 engage processing.That is, altogether the plate of material of toot plate 231 usefulness with the vibration characteristics that is suitable for vibrating body 224 and magnetic characteristic imposes punch process and becomes discoideus, and equally, magnetic sheet 232 is also formed by the plate of magnetic material punch process.Again, will be total to that toot plate 231 is put the limit, magnetic sheet 232 is placed on bottom, sandwich between the electrode 224,246 of spot welding machine 242, with magnetic sheet 232 be welded on toot plate 231 altogether in be formed centrally vibrating body 224.Thereby, in the formation of vibrating body 224, the essential out of the ordinary press work of making toot plate 231, magnetic sheet 232 altogether, both processing of welding job etc.
, form toot plate 231 and magnetic sheet 232 altogether, as shown in figure 14, form burr 248,250 in the marginal portion that is total to toot plate 231 and magnetic sheet 232 in order to adopt punch process.248,250 pairs of engagement states that are total to toot plate 231 and magnetic sheet 232 of each burr are influential, and the result will make the direction of each burr 248,250 as one man engage toot plate 231 and magnetic sheet 232 altogether.Thisly make the processing of the directivity unanimity of burr 248,250 increase the manufacturing procedure number.
The occasion of the direction unanimity that does not make burr 248,250 produce following improper.For example, shown in Figure 15 (A), allow burr 248,250 engage toot plate 231 and magnetic sheet 232 altogether mutually on the contrary, the support step 228 of the lower casing 204 of burr 248 contact electric acoustic converters has been total to the status of support instability of toot plate 231.Burr 248 produces different formerly at the edge of common toot plate 231, vibrating body 224 is configuration obliquely with the height of burr 248, the result, and the vibrational state of vibrating body 224 is affected with burr 248.
Also have, shown in Figure 15 (B), the burr 250 of magnetic sheet 232 contacts and is being configured on toot plate 231 these one side faces altogether, and burr 250 becomes and has influence on both welded conditions, probably can take place to weld crooked because of magnetic sheet 232 from being total to toot plate 231 come-ups etc.And in the occasion of Figure 15 (B), magnetic sheet 232 is welded on one side, the back side of the burr 248 of vibrating body 224, the result, and improper the increasing the weight of of Figure 15 (A) occasion produced.
Again, in the occasion of Figure 15 (C), the improper elimination of Figure 15 (A), but the improper of the occasion of Figure 15 (B) still produces.
Improper like this in order to avoid, in the past, in the formation with vibrating body 224, be necessary to differentiate toot plate 231 and magnetic sheet 232 altogether burr 248,250 have or not distinguish in the surface, in addition, when punch process, must manage like this by nonreversible toot plate 231 altogether and magnetic sheet 232.Particularly, because of altogether toot plate 231 and magnetic sheet 232 are very little, all be in the past a total keeping in container, welding job want many pieces of ground differentiate in the surface send welding electrode to and carry out work like this, but this greatly reduces operating efficiency, probably can go out the substandard products shown in Figure 15 mistakenly.
So, as shown in figure 13, introduce the expression resonance line 252 of the table the inside of toot plate 231 altogether, differentiate in showing as mark with this.Is necessary with resonance line 252 for gathering production being total to attached on toot the plate 231, but its result has made the component processing difficulty, causes the low of quality.In addition, magnetic sheet 232 is carried out same processing, perhaps implement processing with method flash removedes 250 such as pressure processing.Manufacturing cost is increased in such processing, because of surface oxidation becomes the reason that quality descends.
Have again, reason in response to the burr 248,250 that is total to toot plate 231 and magnetic sheet that welds, in order to realize suitable joining process, stained and consume for the electrode surface of the motor 244,246 of spot welding machine 242, essential per grindings of carrying out electrode surface in 30 minutes etc. are necessary to carry out strict management, and each base material of common toot plate 231 and magnetic sheet 232 necessitates to the electric insulation between the press working machine of its punch process, because of the realization difficulty of manufacturing equipment, become the obstacle that automation is handled.
So, the purpose of this invention is to provide a kind of manufacture method of vibrating objects used in electric acoustic exchanger, seek to cut down process number and work simplification improves the vibrating body characteristic simultaneously, stay in grade.
The manufacture method of vibrating objects used in electric acoustic exchanger of the present invention, as be illustrated in as shown in Fig. 1, it is characterized in that transferring and to form toot the slab material (6) altogether of toot plate (4) altogether, after this is total to the magnetic sheet (8) of burn-oning at certain intervals on toot the slab material, above-mentioned toot the slab material that is total to is implemented towards processing, be contained in the vibrating body (2) that is total on toot the plate and form magnetic sheet.
