Abstract
The utility model relates to slim small-bore horn art, particularly a kind of loudspeaker.Comprise: tubular rack body and outer washer; The port of described tubular rack body has washer step groove, and described outer washer is ring-type, is positioned at described washer step groove; Described tubular rack body and outer washer are formed in one structure.According to the technical solution of the utility model, this horn bracket is formed in one structure, is provided with outer washer, makes voice coil vibrations in loudspeaker work not easily encounter the inwall of tubular rack body, decrease the probability causing noise in tubular rack body; In addition, the magnetic field contact-making surface of voice coil loudspeaker voice coil and magnet is less, makes voice coil loudspeaker voice coil be subject to the flux of magnet more concentrated, not easily leakage field and cause magnetic field motive force uneven, and improve acoustical quality, make bass stronger, clear, alt is brighter.
Description
Technical field
The utility model relates to slim small-bore horn art, particularly a kind of loudspeaker.
Background technology
Loudspeaker are loud speaker again, be a kind of very conventional electro-acoustic transducer device, divide moving-coil type (electrodynamic type), condenser type (electrostatic), piezoelectric type (crystal or pottery), electromagnetic type (compressed spring type), electric ion type and pneumatic type loudspeaker etc. by transducing mechanism and structure.
The most common most typical be that cone formula loudspeaker are also called moving-coil type loudspeaker it is made up of three parts:
1. vibrational system, comprises taper cone, voice coil loudspeaker voice coil and centring disk etc.;
2. magnetic circuit system, comprises adopted magnet, magnetic conductive board and field stem etc. forever;
3. auxiliary system, comprises support, terminal block, flanging and dust cap etc.When being in the voice coil loudspeaker voice coil in magnetic field and having tone currents to pass through, just produce the magnetic field with tone currents change, the magnetic field of this magnetic field and permanent magnet interacts, and voice coil loudspeaker voice coil is axially vibrated, because horn structure is simple, bass is plentiful, tonequality is soft, bandwidth, but efficiency is lower.
As shown in Figure 1 to Figure 3, the magnet 1 of existing loudspeaker is fixed on the inner bottom part of tubular horn bracket 2; Interior washer 3 (spring shim) is arranged on the end face of magnet 1; Voice coil loudspeaker voice coil 4 is embedded in the ring cavity that formed at magnet 1 and interior washer 3 and the inwall of tubular horn bracket 2; Diaphragm 5 outer rim is fixed on the port of tubular horn bracket 2, and middle ring is fixed on the top of voice coil loudspeaker voice coil 4.
Because voice coil loudspeaker voice coil 4 stretches in the ring cavity that magnet 1 and interior washer 3 and the inwall of tubular horn bracket 2 formed, in loudspeaker work, voice coil vibrations easily encounters the inwall of tubular horn bracket 2, causes the probability of noise to increase; In addition, voice coil loudspeaker voice coil 4 is excessive with the magnetic field contact-making surface of magnet 1, and the flux making voice coil loudspeaker voice coil 4 be subject to magnet 1 is not concentrated, easy leakage field, and cause magnetic field motive force uneven, weighing apparatus affects acoustical quality, especially bass acoustical quality.
Utility model content
The technical problem that the utility model solves is to provide a kind of loudspeaker, and noise probability is little, and tonequality is good.
For achieving the above object, providing a kind of loudspeaker according to the utility model, comprising: tubular rack body and outer washer; The port of tubular rack body has washer step groove, and outer washer is ring-type, is positioned at washer step groove; Tubular rack body and outer washer are formed in one structure.
Further, tubular rack body comprises: at the bottom of cylinder, barrel and flange, and washer step groove is opened on barrel.
The beneficial effects of the utility model are: according to the technical solution of the utility model, this horn bracket is formed in one structure, be provided with outer washer in tubular rack body, make voice coil vibrations in loudspeaker work not easily encounter the inwall of tubular rack body, decrease the probability causing noise; In addition, the magnetic field contact-making surface of voice coil loudspeaker voice coil and magnet is less, makes voice coil loudspeaker voice coil be subject to the flux of magnet more concentrated, not easily leakage field and cause magnetic field motive force uneven, and improve acoustical quality, make bass stronger, clear, alt is brighter.
Accompanying drawing explanation
Fig. 1 is that the master of existing horn bracket looks assembly structure schematic diagram;
Fig. 2 is that the longitudinal direction of Fig. 1 analyses and observe assembly structure schematic diagram;
Fig. 3 is the backsight assembly structure schematic diagram of existing horn bracket;
Fig. 4 looks assembly structure schematic diagram according to the master of horn bracket of the present utility model;
Fig. 5 is that the longitudinal direction of Fig. 4 analyses and observe assembly structure schematic diagram;
Fig. 6 is the backsight assembly structure schematic diagram according to horn bracket of the present utility model.
Embodiment
Describe embodiment of the present utility model in detail referring to Fig. 4 to Fig. 6 below in conjunction with accompanying drawing and preferred embodiment, these loudspeaker are formed in one structure, specifically comprise: tubular rack body 6 and outer washer 7.Wherein, tubular rack body 6 comprises: at the bottom of cylinder 61, barrel 62 and flange 63, and the port of barrel 62 has the washer step groove extended out.Outer washer 7 is ring-type, is positioned at this washer step groove.
During the assembling of these loudspeaker, magnet 8 is fixed on the inner bottom part of tubular rack body 6; Interior washer 9 (spring shim) is arranged on the end face of magnet 8, and magnet 8 and interior washer 9 form ring cavity with outer washer 7, and voice coil loudspeaker voice coil 10 is embedded in this ring cavity; Diaphragm 11 outer rim is fixed on the flange 63 of tubular rack body 6, and middle ring is fixed on the top of voice coil loudspeaker voice coil 10.
These loudspeaker are formed in one structure, be provided with outer washer 7, make voice coil vibrations in loudspeaker work not easily encounter the inwall of tubular rack body 6, decrease the probability causing noise in tubular rack body 6; In addition, voice coil loudspeaker voice coil 10 is less with the magnetic field contact-making surface of magnet 8, makes voice coil loudspeaker voice coil 10 be subject to the flux of magnet 8 more concentrated, not easily leakage field and cause magnetic field motive force uneven, and improve acoustical quality, make bass stronger, clear, alt is brighter.
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.
