The edge of the diaphragm is connected to the top of the annular ledge, the second washer piece is fastened on the inwall of the U iron cup, the first washer piece is fitted in the top surface of the first annular magnet, the annular gap passed through between the outer wall of the outer wall and first annular magnet of the inwall of the second washer piece and the first washer piece formed with the confession voice coil loudspeaker voice coil bottom edge.
Further, also include being also secured in the U iron cup and being coaxially nested with the second annular magnet in the first annular ferromagnetic outside, the top surface of second annular magnet is connected to the bottom surface of the second washer piece, and the annular gap passed through for the voice coil loudspeaker voice coil bottom edge is also formed between the inwall of second annular magnet and the outer wall of the first annular magnet.
Further, also include the ring support for being connected to the annular ledge bottom, the inner ring edge of the ring support is upwardly extended formed with turned legs, the turned legs both ends open and internal run-through, the top of the turned legs is connected to the bottom surface of the U iron cup and its open top is docked with the through hole；
The attached sound chamber formed with annular is surrounded between the top surface of the bottom interior wall of the annular ledge, the bottom surface of the U iron cup and the ring support, multiple continuant orifices for being communicated to the attached sound chamber are offered on the U iron cup, multiple passages for being communicated to the attached sound chamber are offered on the ring support.
Further, the tuning screen cloth being covered on passage and the turned legs bottom opening is pasted with the bottom surface of the ring support.
The beneficial effects of the invention are as follows：
Double washer Microspeakers in the present invention have double washer, double magnet and dual chamber structures, especially as earphone Microspeaker；Two washer pieces ensure that the vibration balancing of speaker vibration system, and the effect of aggregation magnetic energy, and two magnet provide higher drive efficiency, and dual chamber structure is advantageous to adjust the frequency response of loudspeaker.

Embodiment
Embodiment one
According to Fig. 1 or Fig. 2, the present invention includes a kind of double washer Microspeakers, including diaphragm 1 and the voice coil loudspeaker voice coil 2 for being connected to the bottom of diaphragm 1, in addition to annular ledge 3, the first washer piece 4, the second washer piece 5, the U iron cup 6 being connected to inside annular ledge 3 and the first annular magnet for being fixed on the middle part of U iron cup 6 that section takes the shape of the letter U.
Wherein, the axis of annular ledge 3, first annular magnet 8 and U iron cup 6 is overlapped, and through hole 7 is offered at the bottom centre of U iron cup 6.
The edge of diaphragm 1 is connected to the top of annular ledge 3, second washer piece 5 is fastened on the inwall of U iron cup 6, first washer piece 4 is fitted in the top surface of first annular magnet 8, the annular gap passed through between the outer wall of the outer wall and first annular magnet 8 of the inwall of the second washer piece 5 and the first washer piece 4 formed with the confession bottom edge of voice coil loudspeaker voice coil 2.Because the first washer piece 4 and the structure of the second washer piece 5 easily form the magnetic field of stable and uniform, voice coil loudspeaker voice coil 2 is always positioned in this annular gap during loudspeaker vibration, reduces the possibility of Nonlinear Distortion of Loudspeakers.
