Abstract
The utility model discloses a loudspeaker, comprising a magnetic path system, a vibration system and an auxiliary system, wherein the vibration system comprises a diaphragm, voice coils with upper end portion fixedly connected with the diaphragm, and an elastic wave, and especially the number of the voice coils is at least three. In the utility model, the vibration system are provided with more than three voice coils to drive for vibration, thereby effectively reducing division vibration, enabling a frequency response curve of the product to be more smooth, and enabling the sound quality of the product to be better.
Description
Technical field
the utility model relates to a kind of loud speaker, particularly its vibrational system.
Background technology
loud speaker is claimed " loudspeaker " again, is a kind of ten minutes electro-acoustic transducer device commonly used, is widely used in fields such as TV, multimedias.Loud speaker generally comprises vibrational system, magnetic circuit system and three parts of auxiliary system, and wherein magnetic circuit system comprises permanent magnet, magnetic conductive board; Vibrational system comprises cone (vibrating diaphragm), voice coil loudspeaker voice coil and decides core and prop up sheet (bullet ripple), and whole vibrational system leans on the vibration of voice coil loudspeaker voice coil that power is provided, so voice coil loudspeaker voice coil is " heart " of these loudspeaker, directly determined the life-span of loudspeaker.Existing speaker product or have a voice coil loudspeaker voice coil (driving of single-tone circle) or have two voice coil loudspeaker voice coils (driving of double-tone circle).Yet; Receive the restriction of complete machine mechanism at present, loud speaker is not only wanted the slimming development, and in order to obtain higher sensitivity and better tonequality; Vibrating diaphragm possibly develop toward long but also narrow strip direction not only; This time, the single-tone circle drives or the double-tone circle drive just can't solve the realization product at all effectively cut apart vibration, can't obtain better curve and tonequality.
Summary of the invention
the utility model technical problem to be solved is the deficiency that overcomes prior art, and a kind of improved loud speaker is provided, and it has better curve and tonequality.
the utility model also provides a kind of vibrational system of improved loud speaker simultaneously.
For solving the problems of the technologies described above, the utility model is taked following technical scheme:
a kind of loud speaker, it comprises magnetic circuit system, vibrational system and auxiliary system, said vibrational system comprises the voice coil loudspeaker voice coil that vibrating diaphragm, upper end and vibrating diaphragm are fixedly connected and plays ripple that particularly: voice coil loudspeaker voice coil has three at least.
preferably, described voice coil loudspeaker voice coil is 3,4,5 or 6.
preferably, described vibrating diaphragm is a strip, a plurality of said voice coil loudspeaker voice coils are arranged side by side along the length direction of vibrating diaphragm.Bond between the upper end of voice coil loudspeaker voice coil and the vibrating diaphragm,, can improve the tonequality of product through adjustment voice coil loudspeaker voice coil and vibrating diaphragm bond locations.
The another technical scheme that
the utility model is taked is: a kind of vibrational system of loud speaker, it comprises the voice coil loudspeaker voice coil that vibrating diaphragm, upper end and vibrating diaphragm are fixedly connected and plays ripple that particularly: voice coil loudspeaker voice coil has three at least.
Because the enforcement of above technical scheme, the utility model compared with prior art has following advantage:
The vibrational system of
the utility model drives vibration by three above voice coil loudspeaker voice coils, can effectively reduce and cut apart vibration, makes the product frequency response curve more level and smooth, thereby gives product better tonequality.
Description of drawings
are done further detailed explanation below in conjunction with accompanying drawing and concrete embodiment to the utility model.
Fig. 1 is the structural representation according to the vibrational system of the utility model;
Fig. 2 is the schematic top plan view of Fig. 1;
Fig. 3 is the frequency response curve figure according to the loud speaker of the utility model;
Fig. 4 is the frequency response curve figure that the single-tone circle of prior art drives loud speaker;
Fig. 5 is the frequency response curve figure that the double-tone circle of prior art drives loud speaker;
wherein: 1, vibrating diaphragm; 2, voice coil loudspeaker voice coil.
Embodiment
comprise magnetic circuit system, vibrational system and auxiliary system according to the loud speaker of present embodiment, and present embodiment relates generally to the improvement to vibrational system.
are as illustrated in fig. 1 and 2, and the vibrating diaphragm 1, upper end that vibrational system comprises strip is respectively with bonding 4 voice coil loudspeaker voice coils 4 of vibrating diaphragm 1 and play the ripple (not shown).4 voice coil loudspeaker voice coils evenly distribute along the length direction of vibrating diaphragm 1.
to shown in Figure 5, the frequency response curve of the loud speaker of present embodiment drives loud speaker with existing single-tone circle and compares with double-tone circle driving loud speaker like Fig. 3, and its frequency response curve is more level and smooth, shows that tonequality is better.
More than the utility model has been done detailed description; Its purpose is to let the personage that is familiar with this art can understand the content of the utility model and implements; Can not limit the protection range of the utility model with this; All equivalences of doing according to the spirit of the utility model change or modify, and all should be encompassed in the protection range of the utility model
