Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described.
Existing dynamic speaker, including support 1, electromagnetic assembly 2, voice coil loudspeaker voice coil 3 and vibrating diaphragm 4, electromagnetic assembly 2 is by support 1
Support, what voice coil loudspeaker voice coil 3 was arranged on electromagnetic assembly 2 magnetic gap and can free vibration, the peripheral part of vibrating diaphragm 4 passes through ring 5 and is connected to
On support 1, its inner peripheral portion is connected on voice coil loudspeaker voice coil 3, and ring 5 structure mainly has two kinds, and a kind of structure is upper convexity, such as Fig. 1 and
Shown in Fig. 2, another kind of structure is lower convexity, as shown in Figure 3 and Figure 4, mainly according to dome ring direction bonding with vibrating diaphragm
Difference and be divided into above two structure.
The stiffness of ring 5 is one of factor determining harmonic frequency of loudspeakers fo and quality factor q, the quality of speaker because of
Number Q reflects the speaker electromagnetic system damping action size to vibrational system, i.e. reflects the transient response quality of speaker, folding
When ring 5 vibrates, the linear degree of amplitude affects the distortion size of speaker the most to a certain extent, wherein, the quality of speaker because of
The computing formula of number Q:
Q=
Wherein, Q is the quality factor of speaker, and R is the D.C. resistance of voice coil loudspeaker voice coil, and B is magnetic induction density, and L is having of voice coil loudspeaker voice coil
Effect length, m is the equivalent mass of speaker vibration system, and c is the pliable of speaker vibration system.
If Q-value is the highest, showing that speaker vibration system consumed energy is the slowest, resonance is less susceptible to control, in like manner, and Q-value
The lowest, indicate that resonance is more easily controlled.Due to quality factor q reflection is the damping of mechanical system, then at loudspeaker vibration
Time, it is mainly reflected in support system such as sheet and ring 5 consumption, absorption and the vibrating diaphragm to energy of speaker, voice coil loudspeaker voice coil, dust-proof
The inherent consumption to energy of the quality systems such as cap, this is all relevant with the factor of speaker own for the value of R, B, L, m, if R, B, L,
The value of m does not produce change, and when the diaphragm of loudspeaker is in vibration, the pliable C of vibrational system, if using above-mentioned two kind ring
Structure, when the diaphragm of loudspeaker is at large-amplitude oscillation, the pliable C of its ring 5 can be deteriorated, extreme case even twist distortion,
Thus distortion becomes big, transient response is deteriorated, and low-frequency effect becomes ambiguous, and low frequency is unable.
The technical scheme that this utility model provides can effectively change above-mentioned situation so that the pliable C of ring 5 will be with cone
Basin vibrates and changes, thus improves when large-amplitude oscillation, and distortion becomes the defects such as big, transient response variation.
As viewed in figures 5-8, the technical solution adopted in the utility model is as follows.
Other parts of the present utility model are similar to existing loadspeaker structure, do not repeat at this, of the present utility model
Improvements are at ring 5, and the ring 5 of ventional loudspeakers had already described above, and ring 5 of the present utility model uses
Pipeline ring, ring 5 is pipeline shape, and duct type ring can be engaged by two dome rings 51 and about 52 and form one knot
Structure, it is also possible to the pipe-like being made of one by mould, pipeline ring side be connected on support, opposite side is connected to shake
On film 4, then vibrating diaphragm 4 is being connected to voice coil loudspeaker voice coil 3, and the upper wall of pipeline ring has 3-4 steam vent 53, the size of steam vent 53
Can set according to the concrete condition such as speaker-use, power with, quantity and position.
In order to allow vibrating diaphragm 4 and the ring 5 harmony when vibration, the elastic modelling quantity of pipeline ring and the elasticity of described vibrating diaphragm 4
Modulus is consistent, and upper dome ring 51 is consistent with the elastic modelling quantity of lower dome ring 52, can all use commaterial to make.
During vibration, the air within ring will be compressed release or inflation resilience, pipeline ring upper by steam vent
The interaction of wall and lower wall, the difference of deformation difficulty or ease when mutually compensating for axially-movable, pliable C will be with boring basin vibration and becoming
Changing, according to above-mentioned formula, in the case of ceteris paribus, quality factor q also can change therewith, and vibration amplitude is the biggest, deformation
It is the easiest that difficulty or ease compensate, and the pliable c of speaker is the biggest, then Q-value will be the least, and resonance is more easily controlled, and reduces distortion,
Transient response becomes good, and low-frequency effect becomes strong and energy is pure, and tonequality is the most mellow and the fullest, substantially improves the tonequality effect of speaker
Really.
Embodiment of the present utility model simply introduces its detailed description of the invention, does not lies in and limits its protection domain.The industry
Technical staff under the inspiration of the present embodiment, may be made that some is revised, therefore all done according to this utility model the scope of the claims
Equivalence change or modification, belong in this utility model scope of the patent claims.
