Abstract
The invention discloses a loudspeaker with a built-in spider. The loudspeaker comprises a magnetic loop, a bracket, a voice coil, a vibration system and a voice coil support module. The magnetic loop forms a gap through which a magnetic field passes. The bracket is connected to the magnetic loop, and is extended and raised along a direction away from the magnetic loop. The voice coil is extended into the gap, and when electrified, acts with the magnetic field to vibrate. The vibration system is connected between the voice coil and the bracket, and is driven to produce sounds when the voice coil moves. The voice coil support module of the loudspeaker is provided with a support and the spider, wherein the support is arranged in the voice coil, and is connected to the top of middle position of the magnetic loop; and the spider is elastic, and is connected with the support and the inner surface or top of the voice coil. Therefore, the axial movement of the voice coil can be well kept and the radial movement of the voice coil can be reduced to avoid the voice coil colliding with the magnetic loop and also increase the aperture of the voice coil to thin the loudspeaker and improve power.
Description
Technical field
The present invention relates to a kind of loud speaker, refer to that especially a kind of voice coil loudspeaker voice coil that makes can not collide the magnetism loop with internally-arranged type bullet wave structure, can be so that the bore of voice coil loudspeaker voice coil be bigger, thus make more thin typeization of loud speaker, the loud speaker that power improves more.
Background technology
The structure of existing loud speaker (external magnetic type as shown in Figure 1, internal magnetic type as shown in Figure 2) mainly comprises magnetism loop 1, gap 11, voice coil loudspeaker voice coil 2, plays ripple 3, vibrational system 4, support 5.Magnetism loop 1 11 provides a stable magnetic field in the gap, voice coil loudspeaker voice coil 2 is placed in the gap 11 in magnetism loop 1, voice coil loudspeaker voice coil 2 makes voice coil loudspeaker voice coil 2 vibrate with the effect that magnetism loop 1 produces power when voice coil loudspeaker voice coil 2 energisings, this vibrational system 4 is connected between this voice coil loudspeaker voice coil 2 and the support 5, drives vibrational system 4 and promote air and sound when voice coil loudspeaker voice coil 2 motion.Play ripple 3 required restoring force of vibrational system 4 vibrations and the axial motion that keeps voice coil loudspeaker voice coil 2 are provided.Support 5 is incorporated into magnetism loop 1, and protrudes along extending away from the direction in magnetism loop 1.
But the voice coil loudspeaker voice coil bore of this structure is restricted, and the voice coil loudspeaker voice coil bore can not be done too greatly, is unfavorable for the thin typeization of loud speaker, also is unfavorable for the raising of power.For this reason, the invention provides a kind of structure that ripple is built in loud speaker that plays, promptly adopt the external diameter that plays ripple to be directly connected in the combined method at voice coil loudspeaker voice coil inside or voice coil loudspeaker voice coil top, this structure can keep the axial motion of voice coil loudspeaker voice coil well, reduce the radial motion of voice coil loudspeaker voice coil, make voice coil loudspeaker voice coil can not touch the magnetism loop; Make that simultaneously the bore of voice coil loudspeaker voice coil is bigger, thereby make more thin typeization of loud speaker, power improves more.
Summary of the invention
For addressing the above problem, the object of the present invention is to provide a kind of axial motion that can keep voice coil loudspeaker voice coil well, reduce the radial motion of voice coil loudspeaker voice coil, make voice coil loudspeaker voice coil can not touch the magnetism loop; Make that simultaneously the bore of voice coil loudspeaker voice coil is bigger, thereby make more thin typeization of loud speaker, the loud speaker that power improves more.
The loud speaker of internally-arranged type bullet wave structure of the present invention, it mainly comprises one in magnetism loop, one of voice coil loudspeaker voice coil, one of vibrational system, one on support, one of voice coil loudspeaker voice coil supporting module; The loud speaker of internally-arranged type bullet wave structure of the present invention, its structure is: support is connected on the magnetism loop, the pillar of voice coil loudspeaker voice coil supporting module is placed on the head in centre position, magnetism loop, the bullet ripple of voice coil loudspeaker voice coil supporting module is connected in this pillar and voice coil loudspeaker voice coil inner face or top, and vibrational system is connected between voice coil loudspeaker voice coil and the support.Wherein the magnetism loop provides a stable magnetic field for loud speaker, and voice coil loudspeaker voice coil is placed in the gap in magnetism loop, the action of a magnetic field in voice coil loudspeaker voice coil and magnetism loop during energising and vibration vertically, and vibrational system is vibrated and is promoted air and sound owing to the vibration of voice coil loudspeaker voice coil.
Compare with existing bullet wave structure, the voice coil loudspeaker voice coil supporting module provides vibration required restoring force except the axial vibration for voice coil loudspeaker voice coil, the axial motion that keeps voice coil loudspeaker voice coil, reduce the radial motion of voice coil loudspeaker voice coil, avoid voice coil loudspeaker voice coil owing to vibration is touched outside the magnetism loop, the more important thing is that this module can also make that the bore of voice coil loudspeaker voice coil is bigger, make more thin typeization of loud speaker, power improves more.
