Definitions
- the present invention relates to a speaker.
- a conventional speaker is configured such that a voice coil body 2 arranged so as to be freely movable in a magnetic circuit 1 is connected to an inner peripheral end of a diaphragm 3, and an outer peripheral end of the diaphragm 3 is connected. Is connected to the frame 5 via the edge 4 and the back surface of the diaphragm 3 is connected to the frame 5 via the suspension holder 6 and the edge 7. The harmonic distortion was reduced and the power linearity was improved.
- a speaker having such a configuration is disclosed in Japanese Patent Application Laid-Open No. 2004-7332.
- the present invention provides a support portion projecting outwardly on the outer peripheral portion of the voice coil body forming the speaker, and the inner peripheral end of the suspension holder and the inner portions of the diaphragm with respect to the support portion and the voice coil body.
- FIG. 1 is a partial sectional view of a speaker according to an embodiment of the present invention.
- FIG. 2 is a detailed view of the vicinity of the support portion of the speaker shown in FIG.
- FIG. 3 is a partial cross-sectional view of a conventional speaker.
- the magnetic circuit 1 arranged at the center of the bottom of the frame 5 that also has iron plate force is formed by combining and bonding a magnet 8, a plate 9, and a yoke 10.
- a magnetic gap 11 is formed that opens from the inner peripheral side surface of the side wall portion 10 a of the yoke 10, the magnet 8, and the outer peripheral side surface of the plate 9 toward the upper surface side in the magnetic circuit 1.
- the voice coil body 2 has a structure in which a coil 2 a is wound around the outer peripheral portion of a cylindrical main body, and is arranged so as to be freely movable in the vertical direction with respect to the magnetic gap 11.
- the diaphragm 3 connected to the upper outer peripheral portion of the voice coil body 2 is vibrated.
- the dust cap 2 as a dust-proof measure is attached to the upper end of the voice coil body 2. b is provided.
- the outer peripheral end portion of the diaphragm 3 is connected to the opening end portion of the frame 5 via the first edge 4, and the inner peripheral end portion is supported by the suspension holder 6.
- the suspension holder 6 has a structure in which the outer peripheral end is connected to the bottom surface side of the frame 5 via the second edge 7 and the other end is integrated with the back surface of the inner peripheral end of the diaphragm 3 by bonding. It is.
- a neck 6a bent downward along the outer peripheral side surface of the voice coil body 2 is provided at the inner peripheral end portion of the suspension holder 6.
- the voice coil body 2, the diaphragm 3, and the suspension holder, which are the power points for driving the voice coil body 2 are located inside the region surrounded by the first edge 4 and the second edge 7 connected to the frame 5. There are 6 connection points.
- the diaphragm 3, the suspension holder 6 and the voice coil body 2 are regarded as one rigid body. In this way, the rolling of the voice coil body 2 can be suppressed, and the diaphragm 3 can be freely moved, so that the harmonic component can be attenuated.
- a support portion 12 protruding outward is provided on the outer peripheral portion of the voice coil body 2, and a suspension holder 6 is provided on the outer peripheral side surface portion of the support portion 12 and the voice coil body 2.
- the inner peripheral end portion of the diaphragm 3 is bonded and fixed to the upper surface portion of the suspension holder 6.
- the inner peripheral diameter 13 of the suspension holder 6 is set larger than the outer peripheral diameter 14 of the voice coil body 2, and the inner peripheral diameter 15 of the diaphragm 3 is set larger than the inner peripheral diameter 13 of the suspension holder 6.
- the inner peripheral diameter 13 of the diaphragm 3 and the suspension holder 6 is the outer periphery at the connection portion of the voice coil body 2. Since the diameter is larger than the diameter 14, the suspension holder 6 and the inner peripheral end portion of the diaphragm 3 are positioned on the support portion 12 without contacting the outer peripheral side surface of the voice coil body 2. Therefore, the influence of the stress caused by positioning on the stagnation state of the first edge 4 and the second edge 7 which has been cited as a conventional problem can be suppressed, so that harmonic distortion in the speaker can be reduced.
- the suspension holder 6 and the diaphragm 3 are bonded and fixed to the voice coil body 2 in such a structure, the following is performed.
- the voice coil for magnetic circuit 1 The body 2 is positioned by jig fixing, and in this state, the neck 6a of the suspension holder 6 in which the second edge 7 is bonded and fixed to the frame 5 is placed on the upper surface of the support portion 12 of the voice coil body 2.
- the suspension holder 6 is positioned on the voice coil body 2, and the neck 6 a is bonded and fixed to the upper surface of the support portion 12 and the outer peripheral side surface of the voice coil body 2.
- the inner peripheral end portion of the diaphragm 3 having the first edge 4 bonded and fixed to the frame 5 is bonded and fixed to the upper surface of the suspension holder 6.
- the adhesive 16 that adheres the support portion 12 and the neck 6a also wraps around the upper surface of the suspension holder 6.
- the provision of the support portion 12 to the voice coil body 2 provides the following effects in bonding and fixing to the suspension holder 6.
- the support 12 functions as a weir that prevents the adhesive 16 from drooping to the coil side through the gap between the voice coil body 2 and the neck 6a. Therefore, the productivity of the speaker can be increased.
- the constituent materials used in the present invention may be known materials.
- the speaker of the present invention is used for a speaker that requires a reduction in harmonic distortion.
- it is suitable as a large input speaker for in-vehicle use.
