The technical scheme is that provide a kind of novel horn, including the cylindrical outer casing of one end open and cover described open
The horn hood of mouth, it is characterised in that：It is additionally included in the enclosure and is open what is set gradually from the outer casing bottom to described
Permanent magnet, coil, vibrating diaphragm and circuit board.
Preferably, outer shell barrel bottom center is provided with annular shallow slot, and the permanent magnet is located in the shallow slot.
Preferably, domes centered on the vibrating diaphragm, the arch at its center are raised to the shell aperture.
Preferably, described coil one end is fixed on the vibrating diaphragm concave side.
Preferably, the outer casing inner wall is circumferentially with inside protuberance, and the vibrating diaphragm side face is resisted against described
On protuberance.
Preferably, it is additionally provided with cushion pad between the circuit board and the vibrating diaphragm.
Preferably, the cushion pad is made up of stainless steel or elastomeric material.
Preferably, the shell or the horn hood are provided with string holes, the lead of the coil and the circuit
The lead of plate is drawn by the string holes.
Preferably, the permanent magnet, the coil and the vibrating diaphragm three center line are coaxial.
Preferably, the shell or the horn hood are made up of magnetically soft alloy material.
A kind of novel horn of the present invention, permanent magnet is arranged on and is provided with out on the inside of the outer casing bottom of acoustic aperture, by vibrating diaphragm and
Circuit board is arranged on horn hood side so that as long as different parts is sequentially arranged in shell by assembling process from bottom to top,
Avoid the repeatedly operation of upset shell, while the protuberance set on shell can readily be fixed and shaken in loudspeaker assembling process
Film, ease of assembly；Shell and horn hood can effectively shield electromagnetic interference using magnetically soft alloy material, improve tonequality, reduce miscellaneous
Sound.
Brief description of the drawings
Fig. 1 is a kind of novel horn structural representation of the present invention；
In figure：1. shell, 2. permanent magnets, 3. coils, 4. vibrating diaphragms, 5. cushion pads, 6. circuit boards, 7. horn hoods, 8. protuberances, 9.
Go out acoustic aperture.
Embodiment
The embodiment of the present invention is described in further detail below.
As shown in figure 1, the present invention a kind of novel horn, including shell 1, permanent magnet 2, coil 3, vibrating diaphragm 4, cushion pad 5,
Circuit board 6, horn hood 7, the shell 1 of tubular is opening up, and its bottom goes out acoustic aperture 9 provided with what is run through, and permanent magnet 2 is fixed and is bonded in
The center of the bottom of shell 1, domes centered on vibrating diaphragm 4, permanent magnet 2 are located at the underface of vibrating diaphragm 4, and coil 3 is fixed on
The concave side of the arch of vibrating diaphragm 4, the inwall of shell 1 are circumferentially with inside protuberance 8, and being resisted against for the side face of vibrating diaphragm 4 level is convex
Go out in portion 8, the top of vibrating diaphragm 4 is provided with circuit board 6, and is fixed in the side wall of shell 1, and cushion pad is provided between vibrating diaphragm 4 and circuit board 6
5, it is made up with balancing influence of the vibrations to circuit board 6, cushion pad 5 caused by vibrating diaphragm 4 of stainless steel or elastomeric material, shell 1 is most
Top is provided with the opening that horn hood 7 seals shell 1.Cushion pad 5 is located at the margin location of vibrating diaphragm 4 with the contact fixed position of vibrating diaphragm 4
Put, the vibrations of such centre of vibrating diaphragm 4 at work will not be influenceed by cushion pad 5.
Magnetically soft alloy is that have high magnetic conductivity and low coercitive a kind of alloy in low-intensity magnetic field, and it is to electromagnetic interference
Shielding action be better than common metal, shell 1 of the invention and horn hood 7 are made of magnetically soft alloy material, use it
To shield external electromagnetic interference so that the permanent magnet 2 inside closed tube shape, the coil formed installed in shell 1 and horn hood 7
3 and circuit board 6 will not be by more electromagnetic interferences, to reach more preferable acoustical quality.
The lead of coil 3 and the lead of circuit board 6 are drawn by the string holes on shell 1 and horn hood 7 respectively（Wherein lead
It is not shown with string holes）, because loudspeaker size is smaller, its thickness of shell 1 only has 0.15-0.20mm, and junction and bearing use
Bond or the mode of buckle is fixedly connected with each part, the loudspeaker assembling process of the present invention is greatly simplified, ease of assembly, especially
It is the circumferentially fixed on protuberance 8 of vibrating diaphragm 4, the protuberance 8 set on shell 1 readily can position and fix vibrating diaphragm 4,
Vibrating diaphragm 4 need to only be taken and be placed on protuberance 8 during installation, operation is more convenient.
Permanent magnet 2, coil 3 and the three's center line of vibrating diaphragm 4 are coaxial, make the sounding more standard of loudspeaker.Cushion pad 5, which is located at, to shake
The edge of film 4 so that cushion pad 5 does not interfere with the normal vibration of vibrating diaphragm 4.
The bottom that permanent magnet 2 is close to the shell 1 for carrying out acoustic aperture 9 of the invention, changes conventional horn
Vibrating diaphragm 4 is fixedly installed on out to the mode of the side of acoustic aperture 9, the loudspeaker made need not stir shell 1 in an assembling process, as long as under
To the step installing component can of previous step one, i.e., will after the opening up placement of shell 1, install successively from top to bottom permanent magnet 2,
Vibrating diaphragm 4, cushion pad 5, circuit board 6 and horn hood 7 with coil 3, greatly facilitate assembling process, particularly super-micro size
Loudspeaker, upset shell 1 it is not easy to operate, installing space is narrow and small, is visually not easy to observe, using said structure arrangement, all process steps
It can ensure that shell 1 need not be overturn, and operating efficiency can be provided.
A kind of above example only present invention embodiment therein, its description is more specific and detailed, but can not
Therefore it is interpreted as the limitation to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art,
Without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection model of the present invention
Enclose.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
