Description
Technical Field
The invention relates to the technical field of moving coil earphones, in particular to a novel earphone moving coil.
Background
The earphone is a common electronic product in daily life, and along with the improvement of science and technology and the improvement of living standard of people, the requirement of people on the earphone is higher and higher. However, in the installation process of the earphone moving coil, because the installation space is small and the parts are generally required to be glued for bonding, the sound outlet hole is easily blocked after the flowing glue is dried, and the sound quality of the earphone is affected.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a novel earphone moving coil, which is used for solving the problem that sound quality is damaged due to the fact that a sound outlet hole is easily blocked when the moving coil is installed.
The purpose of the invention is realized by the following technical scheme:
the utility model provides a novel earphone moving coil, includes iron basin support, bonds vibrating diaphragm, bonding on iron basin support at vibrating diaphragm central point position surface the voice coil loudspeaker voice coil, bonds at the protecting cover of vibrating diaphragm opposite side, the back of iron basin support is equipped with circular bulge and makes its one side near the vibrating diaphragm form cylindrical recess, it has magnet to bond in the recess, and the opposite side of magnet bonds and has the magnetic conduction piece, the free end of voice coil loudspeaker voice coil is arranged in the clearance between magnet and the recess inner wall, iron basin support back border position bonds and has the PCB wiring board, the voice coil loudspeaker voice coil is connected with PCB wiring board electricity, the sound hole has been seted up on the circular bulge, it is arranged in the clearance between magnet and the recess inner wall to go out the sound hole, it has the damping net to bond outside the sound hole.
Furthermore, a hemispherical first salient point is arranged in the middle of the back surface of the circular protrusion.
Furthermore, two second salient points are arranged on the circular protrusion, and the second salient points are respectively located on two sides of the sound outlet hole.
By combining the technical scheme, compared with the prior art, the novel earphone moving coil provided by the invention has the beneficial effects that:
according to the invention, the sound outlet hole is arranged on the circular bulge, so that the sound outlet hole is far away from the gluing part when the vibrating diaphragm is installed, and the sound outlet hole is prevented from being blocked in the vibrating diaphragm installation process; through set up first bump and second bump on circular arch, can avoid moving coil installation and battery installation in-process to go out the sound hole and be stopped up and damage tone quality.
Drawings
Fig. 1 is a schematic structural diagram of a novel earphone moving coil according to the present invention.
Fig. 2 is an exploded view of a novel earphone moving coil according to the present invention.
The loudspeaker comprises a protective cover 1, a vibrating diaphragm 2, a voice coil 3, a magnetic conductive sheet 4, a magnet 5, an iron basin support 6, a circular bulge 61, a first salient point 62, a sound outlet 63, a second salient point 64, a damping net 7 and a PCB wiring board 8.
Detailed Description
To explain in detail the technical features of the present invention and the objects and effects achieved, the following is further described with reference to the accompanying drawings:
as shown in fig. 1-2, a novel earphone moving coil, including iron basin support 6, bond vibrating diaphragm 2 on iron basin support 6, bond at the voice coil loudspeaker voice coil 3 on vibrating diaphragm 2 central point surface, bond at the protecting cover 1 of vibrating diaphragm 2 opposite side, the back of iron basin support 6 is equipped with circular bulge 61 and makes its one side that is close to vibrating diaphragm 2 form cylindrical recess, it has magnet 5 to bond in the recess, and the opposite side of magnet 5 bonds and has magnetic conduction piece 4, the free end of voice coil loudspeaker voice coil 3 is arranged in the clearance between magnet 5 and the recess inner wall, 6 back border position of iron basin support bonds and has PCB wiring board 8, voice coil loudspeaker voice coil 3 is connected with PCB wiring board 8 electricity, sound outlet 63 has been seted up on the circular bulge 61, sound outlet 63 is arranged in the clearance between magnet 5 and the recess inner wall, sound outlet 63 outside bonds and has damping net 7.
In the above embodiment, the sound outlet 63 avoids the installation positions of the magnet 5 and the diaphragm 2, so that the situation that the sound outlet 63 is blocked by glue in the installation process can be avoided, the PCB wiring board 8 converts the input audio signal into the current signal and then enters the voice coil 3, and the magnetic field generated by the current when passing through the voice coil 3 and the magnetic field of the magnet 5 generate an interaction force, so that the voice coil 3 performs axial motion to drive the diaphragm 2 to vibrate.
Preferably, a first convex point 62 in a hemispherical shape is arranged in the middle of the back surface of the circular protrusion 61.
In the above embodiment, the first salient point 62 leaves a gap between the circular protrusion 61 and the component below the circular protrusion when the movable coil is installed, so as to prevent the component below from shielding the sound hole 63, which causes sound quality damage, and the hemispherical first salient point 62 has better stability and longer service life.
Preferably, two second protruding points 64 are arranged on the circular protrusion 61, and the second protruding points 64 are respectively located at two sides of the sound outlet 63.
In the above embodiment, the second bump 64 further protects the sound outlet 63 from the contact of the battery with the sound outlet 63 during the mounting process.
The applicant asserts that the above-described embodiments merely represent the basic principles, principal features and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, and that various changes and modifications can be made by one skilled in the art without departing from the spirit and scope of the invention, which will fall within the scope of the invention as claimed.
The present invention is not limited to the above embodiments, and all embodiments using the similar structure and method to achieve the object of the present invention are within the protection scope of the present invention.
