Description

TECHNICAL FIELD

[0001] The utility model relates to a pneumatic type monomer, especially a pneumatic type monomer using upper and lower supports to clamp a diaphragm. BACKGROUND

[0002] The pneumatic type monomer is a structure commonly used in high-grade loudspeakers or earphones, and is a high-grade sound equipment widely used in today's society. The known pneumatic type monomer includes a base, a support, a magnet set, a diaphragm, two adhesive layers, and a cover. The support is arranged on the base. The support has a first sidewall, a second sidewall, a third sidewall, and a fourth sidewall. The third sidewall is located on the opposite side of the first sidewall, and the fourth sidewall is located on the opposite side of the second sidewall. The magnet set is arranged on the base and located in the support. The diaphragm includes multiple waves. The length direction of each wave is defined as a first end and a second end. The two ends of the length direction of each wave are defined as a first end and a second end. The two adhesive layers are arranged on the end faces of the first ends and the second ends of the multiple waves. The end faces of the multiple first ends of the multiple waves are fixed to the first sidewall by one of the two adhesive layers. The end faces of the multiple second ends of the multiple waves are fixed to the third sidewall by the other of the two adhesive layers. The cover is arranged above the diaphragm and has multiple through holes. After the known pneumatic type monomer is powered on, the magnetic force alternately presses and pushes away the diaphragm, and air is pressed to emit sound along with the audio. Such a design has high efficiency, and the strong magnetic force on the diaphragm can reduce the effective mass reactance or audio impedance, which is the origin of the name "pneumatic type monomer". As can be seen from the above, the pneumatic type monomer folds the planar diaphragm into a wave shape and then drives air using the principle of extrusion. Because the amount of air driven is more than that of the traditional planar diaphragm, the efficiency is higher.

[0003] However, the multiple adhesive layers are easily extruded by the first sidewall and the third sidewall of the support and spread to other places of the multiple waves, affecting the output sound quality.

[0004] Furthermore, the multiple adhesive layers are difficult to be coated on the end faces of the multiple first ends and the multiple second ends of the multiple waves by a machine. Users can only manually coat the adhesive layers on the end faces of the multiple first ends and the multiple second ends of the multiple waves and then manually fix the diaphragm on the support, which cannot be automatically produced.

Thus, the positioning effect of the lower support 20, the upper support 40 and the diaphragm 50 is improved by the combination of the protrusions 221, 241, the through holes 521 and the grooves 421, 441, the end portions 52 cannot deviate from the original position, the assembly precision is improved, the lower support 20, the upper support 40 and the diaphragm 50 are easier to be assembled by the mechanical arm, and the feasibility of automatic production of the utility model is improved.

[0043] Preferably, as shown, Figure 2 Thus, the magnet group 30 of the utility model only has a single magnet 31, the single magnet 31 can be directly placed on the base 10 by the mechanical arm, the utility model is easy to assemble, and the feasibility of automatic production of the utility model is improved.

[0044] In some embodiments, the teeth 211 of the first side wall 21 of the lower support 20 and the teeth 411 of the first side wall 41 of the upper support 40 are welded to the upper and lower surfaces of the inner side of the first end 511 of the wave 51 by high-frequency or ultrasonic welding, and the teeth 231 of the third side wall 23 of the lower support 20 and the teeth 431 of the third side wall 43 of the upper support 40 are welded to the upper and lower surfaces of the inner side of the second end 512 of the wave 51 by high-frequency or ultrasonic welding.

[0045] Thus, the fixing effect of the lower support 20, the upper support 40 and the diaphragm 50 is improved by the high-frequency or ultrasonic welding technology.

[0046] Furthermore, after the assembly of each component of the utility model is completed, the high-frequency or ultrasonic welding of the pneumatic single body of the utility model is performed by using a high-frequency welding machine or an ultrasonic welding machine, so that the utility model can be produced by using automatic equipment throughout the process, without manual work, and the labor cost is saved.

[0047] Figure 9 is a front view of the second embodiment of the present utility model. Figure 10 is a rear view of the second embodiment of the present utility model. Figure 9 and Figure 10 As shown in the drawings, the difference between the second embodiment and the first embodiment is that the pneumatic single body of the present utility model further comprises two lower glue layers 70, which are respectively arranged on the upper surfaces of the plurality of tooth portions 211 of the first side wall 21 of the lower support 20 and the upper surfaces of the plurality of tooth portions 231 of the third side wall 23 of the lower support 20. The lower surfaces of the inner sides of the plurality of first ends 511 of the plurality of waves 51 contact one of the two lower glue layers 70, and the lower surfaces of the inner sides of the plurality of second ends 512 of the plurality of waves 51 contact the other of the two lower glue layers 70.

[0048] Therefore, the present utility model can improve the fixing effect of the diaphragm 50 and the lower support 20 by the two lower glue layers 70.

[0049] In addition, because the two lower glue layers 70 are directly coated on the plurality of tooth portions 211 of the first side wall 21 of the lower support 20 and the plurality of tooth portions 231 of the third side wall 23 of the lower support 20, and the plurality of waves 51 only slightly contact the two lower glue layers 70 without pressing the two lower glue layers 70, the two lower glue layers 70 will not spread to other places of the plurality of waves 51, thereby avoiding affecting the output sound quality.

[0050] Furthermore, the two lower glue layers 70 can be easily coated on the plurality of tooth portions 211 of the first side wall 21 of the lower support 20 and the plurality of tooth portions 231 of the third side wall 23 of the lower support 20 by a machine, so that the present utility model can be produced by using automatic equipment throughout the process without manual work, thereby saving labor cost.

[0051] Figure 11 is a front view of the third embodiment of the present utility model. Figure 12 is a rear view of the third embodiment of the present utility model.

The upper surfaces of the inner sides of the plurality of first ends 511 of the plurality of waves 51 contact one of the plurality of upper glue layers 80, and the upper surfaces of the inner sides of the plurality of second ends 512 of the plurality of waves 51 contact the other of the plurality of upper glue layers 80.

[0052] Therefore, the present utility model can improve the fixing effect of the diaphragm 50

[0053] Furthermore, because the plurality of glue layers 80 are directly coated on the plurality of teeth 411 of the first side wall 41 of the upper support 40 and the plurality of teeth 431 of the third side wall 43 of the upper support 40, and the plurality of waves 51 only slightly contact the plurality of glue layers 80, the plurality of glue layers 80 are not pressed, so the plurality of glue layers 80 do not spread to other places of the plurality of waves 51, avoiding affecting the output sound quality.

[0054] In addition, the plurality of glue layers 80 can be easily coated on the plurality of teeth 411 of the first side wall 41 of the upper support 40 and the plurality of teeth 431 of the third side wall 43 of the upper support 40 by machine, so that the entire process of the utility model can be produced by automatic equipment, without manual work, saving labor costs.
