Background
The sound level of the loudspeaker is mainly determined by the magnetic field intensity of the magnetic steel, and the stronger the magnetic field intensity is, the larger the sound level is. However, the magnetic field strength of the magnetic steel is increased, only the magnetic material with higher magnetic content is used or the volume of the magnetic steel is increased, for example, the volume of the magnetic steel is kept unchanged, the original N35 nd-fe-b magnetic steel is changed into N40 nd-fe-b magnetic steel, other conditions are kept unchanged, and the sound level of the loudspeaker is obviously increased. Or the material N35 of the magnetic steel is kept unchanged, the volume of the magnetic steel is increased, and the sound level is also improved. However, the price of the N40 magnetic steel is much higher than that of N35, the cost of changing the magnetic material is too high, and the volume of the loudspeaker needs to be increased when the volume of the magnetic steel is changed, and the sound level of the loudspeaker with a large volume is higher.

Detailed Description
As shown in fig. 1, a dual magnetic circuit high performance speaker, including clamping ring 1, basin frame 2, magnetism bowl 3, clamping ring 1 sets up between basin frame 2, and basin frame 2 top is provided with type of falling U magnetism bowl 3, and magnetism bowl 3 below is provided with magnet steel 4 and magnet steel 5 down, goes up and is provided with polar plate 6 between magnet steel 4 and the magnet steel 5 down, and the periphery of voice coil loudspeaker voice coil 7 bonds through glue with vibrating diaphragm 8, be provided with dust cap 9 between vibrating diaphragm 8 lower periphery and clamping ring 7 fixed connection clamping ring 1 and the voice coil loudspeaker voice coil 7.
The middle of the pressing ring 1 is provided with a groove, the dust cap 9 is arranged in the groove, the middle of the dust cap 9 is provided with a protruding portion 91, and the top of the protruding portion 91 is abutted to the bottom of the voice coil 7.
The two ends of the dustproof cap 9 are bent outwards and are abutted against the vibrating diaphragm 8.
The pressing ring 1 is connected with the basin frame 2 in a step-type matching way
The top of the basin frame 2 is connected with the magnetic bowl 3 in an inserting way.
The magnetic bowl 3 and the polar plate 6 are made of iron, and the upper magnetic steel 4 and the lower magnetic steel 5 are made of neodymium iron boron.
The upper magnetic steel 4 and the lower magnetic steel 5 are oppositely arranged and respectively stuck on two sides of the polar plate 6.
The working principle of the utility model is explained as follows: the original single magnetic circuit is changed into a double magnetic circuit by adding a lower magnetic steel 5, so that the density of magnetic lines of force passing through the voice coil 7 can be enhanced, namely the magnetic field intensity around the voice coil 7 is enhanced; when the voice coil 7 is electrified to work, due to the electromagnetic induction principle, the electrified coil can generate a magnetic field, the voice coil 7 with the magnetism can be attracted or repelled by the surrounding magnetic field, the loudspeaker is connected with an alternating current signal, the polarity of the voice coil 7 can be periodically changed, the magnetic field around the voice coil 7 is generated by magnetic steel, and the polarity does not change, so that the voice coil 7 can periodically reciprocate, the stronger the surrounding magnetic field is, the larger the amplitude of the voice coil 7 is, the connection between the voice coil 7 and the vibrating diaphragm 8 is realized, and the vibration amplitude of the vibrating diaphragm 8 is enhanced; the loudspeaker is vibrated by the vibrating diaphragm 8 to produce sound, and the sound level of the loudspeaker is improved by increasing the vibration amplitude of the vibrating diaphragm 8.
