Abstract
The utility model provides a horn loudspeaker which consists of a horn and a high pitch driver. The high pitch driver mainly comprises a vibrating film, a voice coil, an upper clamping board, a lower clamping board, a field core and a magnet, wherein a vibrating film chamber is formed between the inner walls of the magnet and the upper clamping board and the peripheral wall of the field core. The horn loudspeaker is characterized in that an isolating ring which is tightly adhered to the periphery of the field core is arranged between the upper clamping board and the magnet; the isolating ring divides the vibrating film into a front vibrating film chamber and a back vibrating film chamber; and the isolating ring is in the shape of a ring. The high pitch driver of the horn loudspeaker is internally provided with the isolating ring, and the horn loudspeaker reduces the compliance of the vibrating film chambers, increases the radiation impedance, improves the radiation efficiency, improves the average sensitivity, leads the orientation of the assembly technology to be more reasonable, improves the assembly technology, and has practical applicability.
Description
Technical field
The utility model relates to a kind of horn speaker, particularly a kind of tonequality of improving, the horn speaker of raising average sensitivity.
Background technology
At present, horn speaker generally is made up of horn and high-pitched driver, and high-pitched driver is made up of vibrating diaphragm, voice coil loudspeaker voice coil, train wheel bridge, lower plate, a core and magnet.Because the vibrating diaphragm chamber that forms between the magnetic gap at voice coil loudspeaker voice coil place and magnet center hole and the field core communicates; This vibrating diaphragm chamber makes that the output of loud speaker is that throat's acoustic pressure of horn weakens, and the output of driver throat reduces.Thereby influence the tonequality of loud speaker, reduced the average sensitivity of loud speaker.
In view of this, in order to overcome above-mentioned shortcoming, this creator is according to practical experience and technical concept, after deliberation, exploitation, and has the utility model to produce eventually.
The utility model content
The utility model is that a kind of horn speaker will be provided, and makes its tonequality of improving loud speaker with solution, increases radiation impedance, improves radiation efficiency, improves the technical problem of average sensitivity.
Solving the problems of the technologies described above the technical scheme that is adopted comprises:
A kind of horn speaker, form by horn and high-pitched driver, this high-pitched driver mainly includes vibrating diaphragm, voice coil loudspeaker voice coil, train wheel bridge, lower plate, a core and magnet, form a vibrating diaphragm chamber between the inwall of this magnet and train wheel bridge and the core periphery wall, it is characterized in that: be provided with one between this train wheel bridge and the magnet and be close to a shading ring of core periphery;
This shading ring is divided into vibrating diaphragm ante-chamber and vibrating diaphragm back cavity two parts to the vibrating diaphragm chamber;
This shading ring shape is circular.
High-pitched driver of the present utility model is provided with shading ring, is not originally having under the situation of shading ring, and voice coil loudspeaker voice coil is worked in the vibrating diaphragm chamber.Set up after the shading ring, shading ring is divided into vibrating diaphragm ante-chamber and vibrating diaphragm back cavity two parts to the vibrating diaphragm chamber, voice coil loudspeaker voice coil is worked in the vibrating diaphragm ante-chamber, blocked the influence of vibrating diaphragm back cavity, reduced the compliance in vibrating diaphragm chamber, made its tonequality of improving loud speaker, increased radiation impedance thereby solved, improve radiation efficiency, improve the technical problem of average sensitivity.
The utility model is simple in structure, and its advantage is as follows:
1, high-pitched driver of the present utility model is provided with shading ring, has reduced the compliance in vibrating diaphragm chamber, has increased radiation impedance, has improved radiation efficiency, improves average sensitivity.
2, the shading ring of high-pitched driver setting of the present utility model makes that the location of assembly technology is more reasonable, has improved assembly technology, and the tool practicality.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a high-pitched driver internal structure schematic diagram of the present utility model.
Fig. 3 is a vibrating diaphragm of the present utility model chamber structure for amplifying schematic diagram.
Embodiment
As shown in Figure 1, 2, be structural representation of the present utility model and high-pitched driver internal structure schematic diagram, this horn speaker, form by horn 20 and high-pitched driver 10, this high-pitched driver 10 mainly includes vibrating diaphragm 11, voice coil loudspeaker voice coil 12, train wheel bridge 13, lower plate 14, a core 15 and magnet 16, form a vibrating diaphragm chamber 17 between the inwall of this magnet 16 and train wheel bridge 13 and core 15 periphery walls, wherein, be provided with a shading ring 18 of being close to a core 15 peripheries between this train wheel bridge 13 and the magnet 16;
As shown in Figure 3, be vibrating diaphragm of the present utility model chamber structure for amplifying schematic diagram, this shading ring 18 is divided into vibrating diaphragm ante-chamber 171 and vibrating diaphragm back cavity 172 two parts to vibrating diaphragm chamber 17;
This shading ring 18 is shaped as circular.
This shading ring 18 for metal or nonmetallic materials made have certain thickness circular.Under the situation that does not have shading ring 18 to exist, voice coil loudspeaker voice coil 12 is worked in vibrating diaphragm chamber 17, has increased after the shading ring 18, and voice coil loudspeaker voice coil 12 is worked in vibrating diaphragm ante-chamber 171, has blocked the influence of vibrating diaphragm back cavity 172, has reduced loud speaker low-frequency range Effect on Performance.
The setting of this kind shading ring 18 has reduced the influence to the loud speaker curve, has increased the average sensitivity of loud speaker, and the cooperation of structure simultaneously makes that the location of assembly technology is more reasonable, has improved assembly technology.
In sum, the utility model has promoted the use effect, has practicality, meets each important document of utility model patent, so propose utility application in accordance with the law.
