Abstract
The utility model relates to a technical field is made to the audio amplifier, especially relates to a horn bracket of hot melt type, which comprises a bracket body, this internal support inner chamber that is equipped with of support horn bracket's neighboring is equipped with damping cloth or net plane, be equipped with the bleeder vent on damping cloth or the net plane damping cloth or net planar below side ring week be equipped with the ladder platform in the support inner chamber, ladder bench ring is equipped with glue week and stops the groove. Save manpower and material cost, improved efficiency, because damping cloth or net planar width and increase makes the width of pasting of PCB and damping cloth or net increase, damping cloth or net and PCB's adhesive strength increasing. The U iron of only moulding plastics when moulding plastics, magnet is not moulded plastics with magnificent department, after moulding plastics, is assembling magnet and hua si. Then it reaches our required support to heat up to melt through three -dimensional machine. The emergence of reduction defective rate that like this can be great.
Description
Technical field
The utility model relates to audio amplifier manufacturing technology field, particularly relates to a kind of horn bracket of heat molten type.
Background technology
Loudspeaker can convert the electrical signal to acoustical signal and be radiated the electroacoustic transducer gone in air.Horn bracket of traditional heat molten type and preparation method thereof is divided into electrodynamic type, electromagnetic type, electrostatic, piezoelectric type, ionic formula and pneumatic type etc. by operation principle.At the loudspeaker of all injection moldings, be all by U iron, magnet, washer by injection moulding one-shot forming, this processing technology because of the material reason of magnet broken.So the fraction defective that magnet breaks aborning can be well high.
Utility model content
The purpose of this utility model is the deficiency overcoming above-mentioned technology, and provides a kind of horn bracket of heat molten type, reduces the generation of fraction defective.
The utility model for achieving the above object, by the following technical solutions:
A kind of horn bracket of heat molten type, it is characterized in that: comprise rack body, rack bore is provided with in described rack body, damping cloth or network plane is provided with in the neighboring of described horn bracket, described damping cloth or network plane are provided with air-vent, in the described rack bore in below of described damping cloth or network plane, side ring week be provided with ladder platform, described ladder platform pressed on ring week is provided with glue stay groove.
Preferably, the annular press strip be mated is provided with in described glue stay groove.
Preferably, the bottom of described rack body is with sound hole.
The beneficial effects of the utility model are: save manpower and material cost, improve efficiency; Because the width of damping cloth or network plane increases, the stickup width of PCB and damping cloth or net is strengthened, the sticking strength of damping cloth or net and PCB strengthens.An injection moulding U iron when injection moulding, magnet and washer do not carry out injection moulding, after the injection-moulding, are carrying out assembling magnet and washer.Then carry out heat by three-dimensional machine to melt and reach our required support.The generation of fraction defective can be reduced so greatly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in Figure 1, a kind of horn bracket of heat molten type, comprise rack body 1, rack bore is provided with in described rack body, damping cloth or network plane 2 is provided with in the neighboring of described horn bracket, described damping cloth or network plane are provided with air-vent, side ring week ladder platform 3 is provided with in the described rack bore in below of described damping cloth or network plane, described ladder platform pressed on ring week is provided with glue stay groove 4, glue stay groove can place the glue of damping cloth or network plane, can ensure that damping cloth is pasted so more firm, rack body adopts hot melt molding.Save manpower and material cost, improve efficiency; Because the width of damping cloth or network plane increases, the stickup width of PCB and damping cloth or net is strengthened, the sticking strength of damping cloth or net and PCB strengthens.An injection moulding U iron when injection moulding, magnet and washer do not carry out injection moulding, after the injection-moulding, are carrying out assembling magnet and washer.Then carry out heat by three-dimensional machine to melt and reach our required support.The generation of fraction defective can be reduced so greatly.
The annular press strip be mated is provided with in described glue stay groove.Damping step can be stuck in glue stay groove by annular press strip, and be fixed further by glue, strengthen the fastness of damping cloth.
The bottom of described rack body is with sound hole 5.Ensure that stability and the consistency of loudspeaker Frequency Response and tonequality performance
The utility model additionally provides a kind of manufacture method of horn bracket of heat molten type, comprises the following steps: step one, first injection moulding U iron, places 3-6 hour in atmosphere after injection mo(u)lding; Step 2, put into magnet 6 and washer 7 successively by the U iron after injection mo(u)lding, assembled formation.Step 3, carries out heat by three-dimensional fuse machine to U iron, magnet and the washer after assembling and melts, finally form required support.In step 2, hot melt glue is placed with between magnet and washer and U iron, by hot melt glue can be of short duration magnet, washer and U iron are fixed, three in moving process is prevented to be subjected to displacement, and affect the relative position of three, after placing PUR, can melt rapidly fixing in reflow process.In order to form difform support, in step 3, U iron, magnet and washer are placed in bracket mould.
Save manpower and material cost, improve efficiency; Because the width of damping cloth or network plane increases, the stickup width of PCB and damping cloth or net is strengthened, the sticking strength of damping cloth or net and PCB strengthens.An injection moulding U iron when injection moulding, magnet and washer do not carry out injection moulding, after the injection-moulding, are carrying out assembling magnet and washer.Then carry out heat by three-dimensional machine to melt and reach our required support.The generation of fraction defective can be reduced so greatly.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
