Abstract
The utility model relates to a horn, comprising a housing and a protecting cover connected with the housing; wherein the housing is provided with a vibrating diaphragm and a magnet therein, a bottom of the housing is provided with a PCB (Printed Circuit Board) and a non-woven fabric, and a coil is wound on the vibrating diaphragm. The horn of the utility model has a reasonable structural design, i.e., the horn of the utility model omits rivets and washers on an original horn structure and reduces the sizes of the housing, the vibrating diaphragm, the coil, the magnet, the PCB, and the non-woven fabric, thus the horn of the utility model reduces materials and reduces costs of horn fittings in the premise of ensuring performances (such as sensitivity and so on) of the horn, therefore, especially in the case that the magnet has a high price at present, production costs of enterprises are greatly reduced.
Description
Technical field
The utility model belongs to the sound appliances technical field, specifically refers to a kind of loudspeaker.
Background technology
Loudspeaker are a kind of electroacoustic components, are used for converting the electrical signal to sound.Common loudspeaker comprise shell 5, are wound with the vibrating diaphragm 2 of coil 3, rivet 8, washer 9, magnet 4, pcb board 7, adhesive-bonded fabric 6 and protecting cover 1, as shown in Figure 1; Although existing loudspeaker sensitivity is higher, for 〉=112dB/W/m, the material that loudspeaker are used is too abundant, and consumptive material is many, and cost is higher.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of loudspeaker, can either guarantee the loudspeaker performance, can reduce production costs again.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of loudspeaker comprise shell and the protecting cover that is connected with shell, are provided with vibrating diaphragm and magnet in the described shell, are provided with pcb board and adhesive-bonded fabric at outer casing bottom, are wound with coil at vibrating diaphragm.
Above-mentioned internal diameter of outer cover is 6.2～6.6mm, and thickness is 1.3～1.5mm.
Above-mentioned vibrating diaphragm internal diameter is for being 5.5～5.9mm.
The wall scroll enamel covered wire diameter of above-mentioned coil is 0.029～0.031mm.
Above-mentioned magnet external diameter is 4.8～5.2mm, and thickness is 0.9～1.1mm.
Above-mentioned pcb board diameter is 6.3～6.7mm, and thickness is 0.3～0.5mm.
Above-mentioned adhesive-bonded fabric internal diameter is 7.2～7.6mm.
The utlity model has following remarkable result:
The utility model horn structure is reasonable in design, two parts of rivet and washer have been deducted on the basis of original technology horn structure, and reduced the size of shell, vibrating diaphragm, coil, magnet, pcb board and adhesive-bonded fabric, on the basis that guarantees the performances such as loudspeaker sensitivity, reduced material, reduced loudspeaker accessory cost, in the situation that the magnet price is more expensive especially at present, enterprise's production cost reduces greatly.
Description of drawings
Embodiment
For the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing and embodiment the utility model is explained in further detail.
As shown in Figure 2, a kind of loudspeaker comprise shell 5 and protecting cover 1, and protecting cover 1 can cooperate installation to link together with shell 5.Wherein, be provided with vibrating diaphragm 2 and magnet 4 in shell 5, be wound with coil 3 at vibrating diaphragm 2, magnet 4 is installed in the mounting groove that defaults in shell 5 inner bottom parts; Be provided with pcb board 6 and adhesive-bonded fabric 7 in shell 5 bottoms.
In the present embodiment, internal diameter of outer cover is 6.2～6.6mm, has guaranteed that magnet 4 is installed in the mounting groove, and is outer
Thickness of the shell is 1.3～1.5mm; Vibrating diaphragm 2 internal diameters are for being 5.5～5.9mm, thereby the ring of vibrating diaphragm 2 is increased, and make vibrating diaphragm 2 be easy to promote under less magnetic force, guarantee the sensitivity of loudspeaker, and can promote the effect of loudspeaker low frequency; The wall scroll enamel covered wire diameter of coil 3 is 0.029～0.031mm; Magnet 4 external diameters are 4.8～5.2mm, and thickness is 0.9～1.1mm; The pcb board diameter is 6.3～6.7mm, and thickness is 0.3～0.5mm; The adhesive-bonded fabric internal diameter is 7.2～7.6mm.
The utility model horn structure is reasonable in design, 9 two parts of rivet 8 and washer have been deducted on the basis of original technology horn structure, and reduced the size of shell 5, vibrating diaphragm 2, coil 3, magnet 4, pcb board 7 and adhesive-bonded fabric 6, on the basis that guarantees the performances such as loudspeaker sensitivity, reduced material, reduced loudspeaker accessory cost, in the situation that magnet 4 prices are more expensive especially at present, enterprise's production cost reduces greatly.
Above-described embodiment only is better execution mode of the present utility model, and in addition, the utility model can also have other implementations.That is to say that under the prerequisite that does not break away from the present utility model design, any apparent replacement all should fall within the protection range of the present utility model.
