Magnetic yoke structure body 4 comprises can form the closed circuit yoke of magnetic flux 41, yoke piece 42 and magnet 43, one side of these yoke 41 agent-oriention shells 1 is concaved with solid magnetic groove 44, magnet 43 and yoke piece 42 this solid magnetic groove 44 of all packing into, yoke 41 and yoke piece 42 are clamped this magnet 43, magnet 43 is fixed with the bottom land of solid magnetic groove 44, yoke piece 42 is fixing with magnet 43, and forms annular spaces 45 between the outer peripheral face of the outer peripheral face of the cell wall of solid magnetic groove 44, magnet 43, yoke piece 42.
The tubular body of coil rack 5 for axially running through, this coil rack has auxiliary section 51 and is positioned at the joint portion 52 of below, auxiliary section, this joint portion 52 is made by heat-barrier material, this auxiliary section 51 is made by Heat Conduction Material, this joint portion 52 is used for fixedlying connected with body shell 1, and this auxiliary section 51 is used for cooperating with coil 6.
Coil 6 is connected with lead 7, and this lead 7 is used for providing the signal of telecommunication to coil 6.
Body shell 1 and loam cake 2 can be made by resistant to elevated temperatures plastic material, the joint portion 52 of coil rack 5 can be made by the thermostable heat insulation material, during coil 6 heating powers, heat can partly be delivered on the joint portion 52 of body shell, loam cake and coil rack, because material is high temperature resistant, can reduce the possibility that body shell, loam cake, coil rack are melted damage as far as possible.
In vibration transducer when assembling, be fixed on the bottom land of the solid magnetic groove 44 of yoke with the upper surface of magnet 43, and yoke piece 42 is fixed on the lower surface of magnet 43, forms magnetic yoke structure body 4; Suspension part 32 by first threaded fastener, 8 locking yokes 41 and supporter makes magnetic yoke structure body 4 be suspended on the below of supporter 3; The joint portion 52 of coil rack is fixed in the location notch 14 of body shell, and on the auxiliary section 52 of coil rack, the lead 7 of connecting coil passes the cable-through hole 15 of body shell with coil 6; By the installation portion 31 of second threaded fastener 9 locking body shell 1 and supporter, make body shell 1 fixedly connected one with supporter 3; Loam cake 2 is embedded the mounting groove 33 of supporter 3.After the assembling, magnetic yoke structure body 4, supporter 3 are between loam cake 2 and body shell 1, and magnetic yoke structure body 4 is positioned at the shell chamber 18 of body shell, and coil 6 stretches in the space 45 of magnetic yoke structure body.
When vibration transducer uses, the signal of telecommunication is provided for coil 6 by lead 7, the magnetic line of force of coil 6 septum magnets 43, because magnetic yoke structure body 4 is suspended on the deformable suspension part 32 of supporter 3, the relative position of magnetic yoke structure body 4 and body shell 1 is changed, magnetic yoke structure body 4 body shell 1 axially on up-down vibration, thereby produce body-sensing vibration.
As Figure 11 and shown in Figure 12, it is second embodiment of coil rack.Make by heat-barrier material the joint portion 52 of this coil rack 5 and free section 51.
The shape of first radiating opening 11 of body shell, size, quantity and distribution can require design according to heat radiation, and be extremely shown in Figure 15 as Figure 13.
Vibration transducer comprises body shell, loam cake, magnetic yoke structure body, coil rack and coil, body shell, loam cake and the fixedly connected one of magnetic yoke structure body, the magnetic yoke structure body overhang is below supporter, coil is on coil rack, coil rack has the joint portion of being made by heat-barrier material, this joint portion and body shell are fixed, and are provided with one of at least radiating opening in body shell and the loam cake.By heat insulation joint portion is set, can reduce or avoid the heat of coil to be directly delivered to body shell and directly dispel the heat by body shell, but utilize flowing of air, the heat radiating opening that passes through is as much as possible dispelled the heat, the radiating efficiency height, simultaneously, because the more radiating opening that passes through of heat dispels the heat, make less being delivered on the magnetic yoke structure body of heat, it is overheated that the magnetic yoke structure body is difficult for.When body shell and loam cake are equipped with radiating opening, be more conducive to the air flows of vibration transducer inside, easier heat radiation.The shape of the radiating opening of body shell and loam cake, size, quantity and distribution can require design according to heat radiation.
For the ease of the set winding skeleton, location notch can be set on body shell.Because the heat of coil mainly dispels the heat by air flows, rather than is delivered on the body shell by coil rack, reduced the matching requirements of coil rack joint portion and body shell, be convenient to the production line operation.
For the ease of the assembling vibration transducer, cable-through hole can be set on body shell, like this, the lead of connecting coil does not just need the position through body shell and loam cake combination, when assembling, can be earlier lead and coil be connected loam cake is installed again, simplified packaging technology, simultaneously, when opening loam cake, can not involve lead, convenient for maintaining yet.
Be subjected to the influence of vibration number and temperature rising for fear of the junction of magnetic yoke structure body and supporter, the magnetic yoke structure body can be connected by threaded fastener with supporter, makes connection between the two more firm.
Because the heat radiation of coil is mainly by the air flows heat radiation, so body shell and loam cake can be made by plastic material.Thereby reduced manufacturing cost.
For vibration transducer, body shell and loam cake constitute housing, and magnetic yoke structure body, supporter, coil rack and coil are positioned at this housing.Body shell and loam cake can be aforementioned structure, also can be existing structure, and perhaps other can place the structure of magnetic yoke structure body, coil and coil rack.The magnetic yoke structure body can be aforementioned structure, also can be existing structure, and perhaps other has magnet and can be by the structure of coil cutting magnetic line.Supporter can be aforementioned structure, also can be existing structure, perhaps other structure that can articulate the magnetic yoke structure body and can make magnetic yoke structure body up-down vibration when coil electricity.Coil rack can whole be made by heat-barrier material, and also only its position that is connected with body shell is made by heat-barrier material.
A kind of body-sensing vibration device comprises carrier and vibration transducer, and this vibration transducer places the inside of this carrier.This body-sensing vibration device is as head massager with vibration transducer, eye massage device, massage armchair, Messaging cushion, Massage sofa etc.
Above content be in conjunction with concrete execution mode to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
