Abstract
A complex impedance speaker. The utility model discloses constitute by support, magnet, magnetic pole core, voice coil loudspeaker voice coil, centering support, cone, connection frame, its characteristics are that the voice coil loudspeaker voice coil is equipped with the impedance that resistance is different more than two groups or two groups, make a speaker can have multiple use concurrently, a thing is multi-purpose to be favorable to reducing product part and volume, reduce material cost, extensively be applicable to the product that needs to use the speaker that a plurality of powers are close and do not work simultaneously again, like telephone, stereo set, doorbell, toy etc..
Description
The utility model relates to a kind of loud speaker, belongs to the improvement of electric elements.
The existing loud speaker that is used for various uses owing to voice coil loudspeaker voice coil has only single impedance have only single power, so a loud speaker only is used for special purpose in a certain product, need use loud speaker as these product many places, corresponding a plurality of loud speaker then need be set satisfy the demand.
The purpose of this utility model is to provide a kind of composite impedance loud speaker with different resistances, uses this loud speaker, helps to reduce small product size and reduces product cost.
The utility model as shown in drawings, by support (1), magnet (2), magnetic pole core (3), voice coil loudspeaker voice coil (4), a centering part (7), cone (8) and patch bay (10) are formed, wherein voice coil loudspeaker voice coil (4) is positioned at the endless groove (13) between magnet (2) and the magnetic pole core (3), patch bay (10) is fixed on the floor of support (1) back side, patch bay (10) is provided with lug plate (11), it is characterized in that above-mentioned voice coil loudspeaker voice coil (4) comprises two groups or two groups of above impedances that resistance is different, patch bay (10) is correspondingly provided with more than two or two, and each is organized impedance and connects with lug plate (11) on the corresponding patch bay (10) by lead-out wire (6) respectively.
The utility model is owing to have the different impedance of many group resistances, a loud speaker has multiple use concurrently, one-object-many-purposes, thereby help reducing product parts and volume, reduce material cost, be widely used in needing the product of and the loud speaker of again simultaneously not working close, as telephone set, sound equipment, doorbell, toy etc. with a plurality of power.
Fig. 1 is the utility model end view;
Fig. 2 is the utility model rearview;
Embodiment: this example as shown in Figure 1 and Figure 2, form by support (1), magnet (2), magnetic pole core (3), voice coil loudspeaker voice coil (4), centring disk (7), cone (8), patch bay (10), wherein magnet (2) is enclosed within outside magnetic pole core (3) core body, be formed with endless groove (13) therebetween, magnet (2) is adhesively fixed by epoxy resin and magnetic pole core (3) base plate; This routine voice coil loudspeaker voice coil (4) is provided with two groups of impedances and lap wound becomes four layers, wherein first and second layer is one group of impedance, resistance is 25 Ω, third and fourth layer is one group, resistance is 8 Ω, and voice coil loudspeaker voice coil (4) is arranged in the endless groove (13), and patch bay (10) is correspondingly provided with two, be fixed on the different floor in support (1) back side by rivet respectively, the two ends lead of every group of impedance connects with two lug plates (11) on the patch bay (10) by two lead-out wires (6) respectively; Support (1) is connected into one by retainer plate (12) and magnet (2), and cone (8) periphery compresses and cements on the support (1) by pad limit (9); Centring disk (7) is fixed in voice coil loudspeaker voice coil (4) front portion and is close to cone (8), plays the effect of supporting and transmitting voice coil loudspeaker voice coil (4) vibration; Lead-out wire (6) need pass cone (8) surface, for attractive in appearance and fix its position, generally uses black enamel paint to be fixed on cone (8) surface lead-out wire (6) is deadlocked.
For dustproof, voice coil loudspeaker voice coil (4) front end face is provided with dust cover (5), and it is bonded together with black enamel paint and voice coil loudspeaker voice coil (3) paper ring front end face.
This routine loud speaker can be used in the telephone set, is used for ring simultaneously and is subjected to words (little resistance impedance is used for ring, big resistance is used to be talked about), and a thing dual-purpose can be saved a loud speaker, thereby reduces telephone set volume and cost of manufacture.
It is to be noted that in addition a plurality of patch bays (10) can economize slightly one, a plurality of lug plates (11) are concentrated and are arranged on the patch bay (10), and an end lead of organizing impedance also can a shared lug plate (11) more.
Claims (3)
1, a kind of composite impedance loud speaker, by support (1), magnet (2), magnetic pole core (3), voice coil loudspeaker voice coil (4), a centering part (7), cone (8) and patch bay (10) are formed, wherein voice coil loudspeaker voice coil (4) is positioned at the endless groove (13) between magnet (2) and the magnetic pole core (3), patch bay (10) is fixed on the floor of support (1) back side, patch bay (10) is provided with lug plate (11), it is characterized in that above-mentioned voice coil loudspeaker voice coil (14) comprises two groups or two groups of above impedances that resistance is different, patch bay (10) is correspondingly provided with more than two or two, and each is organized impedance and connects with lug plate (11) on the corresponding patch bay (10) by lead-out wire (6) respectively.
2, loud speaker according to claim 1, it is characterized in that above-mentioned voice coil loudspeaker voice coil (4) is provided with two groups of impedances and lap wound becomes four layers, wherein one, two layer is one group, three, four layers is another group, patch bay (10) is correspondingly provided with two, and the two ends lead of every group of impedance connects with two lug plates (11) on the patch bay (10) by two lead-out wires (6).
3, loud speaker according to claim 1 and 2 is characterized in that above-mentioned a plurality of patch bay (10) can be combined to one, and many set of connections sheet (11) is arranged on the same patch bay (10).
