Description
Technical field
Loudspeaker field is the utility model is related to, more particularly to a kind of double magnetic circuit two-tone film loudspeaker.
Background technology
Our most common electrodynamic type taper cone loudspeakers.I.e. we are usual to speak cone to dynamic cone speaker in the past
Loudspeaker, although many high polymer material vibrating diaphragms, metal vibration diaphragm still based on cone, occurs in vibrating diaphragm in 2014 simultaneously, use
Cone loudspeaker address is just worthy of the name.Taper cone loudspeaker is substantially by magnetic loop system (permanent magnet, stem, magnetic conduction
Plate), the three parts such as vibrational system (cone, voice coil loudspeaker voice coil) and support auxiliary system (centring disk, frame, pad side) form.But
Similarly it is single-tone film, single magnetic circuit state.
At present, on the market in earphone horn product, loudspeaker product is single-tone membrane stage.Lack low, the complementary knot of high frequency
Structure, easily interfere, make tonequality not ideal enough.
Utility model content
The purpose of this utility model is aiming above technical problem, there is provided a kind of double magnetic circuit two-tone film loudspeaker, using double
Sound film controls low frequency and high frequency respectively, and sound film individually arranges, and high frequency is complementary with low frequency and does not disturb, so that low frequency is simple and honest, high
Frequency is clear..
Technical problem of the present utility model is mainly addressed by following technical proposals：
Double magnetic circuit two-tone film loudspeaker, including PCBA, external shell and top cover, overall structure is in boss-shaped, and is provided with
Overhead support I and underlying holder II are fixed with housing assembling；
The support I is provided with T iron, and the T iron is provided with voice coil loudspeaker voice coil I, magnet I, and the magnet I is located at the periphery of voice coil loudspeaker voice coil I, described
The top of voice coil loudspeaker voice coil I is provided with sound film I, is connected between the outside of voice coil loudspeaker voice coil I, the top of magnet I, the outer shroud bottom three of sound film I provided with washer I
It is fixed, it is additionally provided with tuning cloth I below the T iron；
The support II is provided with U iron, is provided with voice coil loudspeaker voice coil II, magnet II in the U iron, the magnet II is located in voice coil loudspeaker voice coil II
Ring, the top of voice coil loudspeaker voice coil II are provided with sound film II, and the inner side of voice coil loudspeaker voice coil II, magnet II are connected between top provided with washer II,
Tuning cloth II is additionally provided with the U iron.
Further, the sound film I is smaller than sound film II.
Further, the voice coil loudspeaker voice coil I is smaller than voice coil loudspeaker voice coil II.
Further, the tuning cloth I is smaller than tuning cloth II.
Preferably, the support I, support II, housing are plastic material.
The beneficial effects of the utility model are：Using double magnetic circuit two-tone Design of Membrane Structure, difference management and control low frequency (big sound film)
With high frequency (small sound film), after audio input, high bass film vibrates simultaneously, and low-and high-frequency is complementary, so that low frequency is simple and honest, high frequency is clear
It is clear.In addition, profile stent structure is plastics, production cost is low, and technique is simple, and production efficiency is high.

Embodiment
Below by embodiment, and with reference to accompanying drawing 1-3, the technical solution of the utility model is made more specifically
It is bright.
Double magnetic circuit two-tone film loudspeaker, using double magnetic circuit two-tone Design of Membrane Structure, difference management and control low frequency (sound film II 202) and height
Frequently (sound film I 201), after audio input, high bass film vibrates simultaneously, and low-and high-frequency is complementary, so that low frequency is simple and honest, high frequency is clear
It is clear.Double magnetic circuit two-tone film loudspeaker include PCBA9, external shell 10 and top cover 1, and PCBA9 is located at the inner bottom part of housing 10, overall
Structure is in boss-shaped, and is fixed provided with overhead support I 801 and underlying holder II 802 with the assembling of housing 10；Housing 10 is by left and right two
Part is assembled.
The support I 801 is provided with T iron 601, and the T iron 601 is provided with voice coil loudspeaker voice coil I 301, magnet I 501, the magnet I 501
It is located at the periphery of voice coil loudspeaker voice coil I 301, the top of voice coil loudspeaker voice coil I 301 is provided with sound film I 201, at the top of the outside of voice coil loudspeaker voice coil I 301, magnet I 501,
