As shown in fig. 1 to fig. 4, the mechanism for frequency division sounding of a coaxial double-acting coil module according to one embodiment of the present invention includes a housing 1, a first moving coil 2 and a second moving coil 3 are disposed inside the housing 1, the second moving coil 3 is disposed coaxially with the first moving coil 2, and the second moving coil 3 has a frequency different from that of the first moving coil 2, the housing 1 includes an outer housing 101, an inner housing 102 disposed inside the outer housing 101, a gap is left between the outer housing 101 and the inner housing 102, and the inner housing 102 is intermittently connected through a connecting block, the outer housing 101 is provided with a first opening 1011 on one side of an in-ear, and the inner housing 102 is provided with a second opening 1021 on the same side of the first opening 1011; the inner cavity of the outer shell 101 sequentially comprises a first accommodating cavity 1012, a first flow guiding cavity 1013 and a first sound outlet cavity 1014 from inside to the first opening 1011, the first moving coil 2 is arranged in the first accommodating cavity 1012, the first flow guiding cavity 1013 and the first sound outlet cavity 1014 are channels between the outer shell 101 and the inner shell 102, and one side of the first flow guiding cavity 1013 close to the first sound outlet cavity 1014 is a transition surface 1015, so that the diameter of the first flow guiding cavity 1013 is gradually reduced to be equivalent to the diameter of the first sound outlet cavity 1014; the inner chamber of the inner shell 102 sequentially comprises a second accommodating cavity 1022, a second guiding cavity 1023 and a second sound outlet cavity 1024 from inside to the second opening 1021, the second moving coil 3 is arranged in the second accommodating cavity 1022, and one side of the second guiding cavity 1023 close to the second sound outlet cavity 1024 is also a transition surface 1015, so that the diameter of the second guiding cavity 1023 is gradually reduced to be equivalent to the diameter of the second sound outlet cavity 1024.
In this example, by dividing the housing 1 into the inner case 102 and the outer case 101, the first moving coil 2 and the second moving coil 3 are respectively provided in the outer case 101 and the inner case 102, respectively, and the inner case 102 is provided between the first moving coil 2 and the second moving coil 3 such that the first moving coil 2 and the second moving coil 3 are relatively independent. On the one hand, a first accommodating cavity 1012 and a second accommodating cavity 1022 are respectively arranged in the outer shell 101 and the inner shell 102, and the first accommodating cavity 1012 and the second accommodating cavity 1022 are respectively used for accommodating the first moving coil 2 and the second moving coil 3 and protecting the first moving coil 2 and the second moving coil 3; on the other hand, the sound cavity of the first moving coil 2 and the sound cavity of the second moving coil 3 are divided into two relatively independent sound cavities by the inner case 102, so that the mutual interference between the first moving coil 2 and the second moving coil 3 is reduced, and the mutual interference between the sounds emitted by the first moving coil 2 and the second moving coil 3 is also reduced. In addition, the first moving coil 2 and the second moving coil 3 are double moving coils which are coaxially designed, and two-way frequency division is also performed. One of the first moving coil 2 and the second moving coil 3 is responsible for high frequency, the other is responsible for middle and low frequency, and according to different frequency response requirements and material characteristics, an independent top-level middle bass unit and an independent top-level high bass unit are respectively designed and manufactured, so that the respective advantages of the large moving coil and the small moving coil are exerted. If the first moving coil 2 is a middle-low frequency moving coil, the second moving coil 3 is a high frequency moving coil. The first moving coil 2 and the second moving coil 3 are independent cavity structures connected in series, as shown by arrow directions in fig. 3, sound emitted by the first moving coil 2 is guided into the first sound outlet cavity 1014 through the first guiding cavity 1013, then enters the auditory canal through the first opening 1011, sound emitted by the second moving coil 3 is guided into the second sound outlet cavity 1024 through the second guiding cavity 1023, then enters the auditory canal through the second opening 1021, namely, sound emitted by the first moving coil 2 and the second moving coil 3 are respectively output into the auditory canal through the respective sound cavities to be mixed, and compared with the sound quality of the single-sound-coil sounding structure, the sound quality is further improved.
In this example, in the process that the sound emitted by the first moving coil 2 is guided to the first sound outlet cavity 1014 through the first guiding cavity 1013, the transition surface 1015 is disposed between the first guiding cavity 1013 and the first sound outlet cavity 1014, so that the cross-sectional diameter of the first guiding cavity 1013 is gradually the same as the cross-sectional diameter of the first sound outlet cavity 1014, so that the energy loss of the sound emitted by the first moving coil 2 is less when the sound passes through the transition surface 1015, and the middle-low frequency sound quality is ensured. Similarly, in the process that the sound emitted by the second moving coil 3 is guided to the second sound outlet cavity 1024 through the second guiding cavity 1023, as the transition surface 1015 is also arranged between the second guiding cavity 1023 and the second sound outlet cavity 1024, the cross section diameter of the second guiding cavity 1023 is gradually the same as that of the second sound outlet cavity 1024, so that the energy loss of the sound emitted by the second moving coil 3 is less when the sound passes through the transition surface 1015, and the tone quality of a high-frequency part is ensured. Through set up the transition face 1015 respectively in the sound chamber of first moving coil 2 and second moving coil 3 for the sound is less at the in-process energy loss of propagation, guarantees that the sound of each frequency channel is clear to be gone into the ear canal, still keeps the uniformity of each frequency channel sound simultaneously, brings good sound field experience, constructs high-quality tone quality.
In this example, the transition surface 1015 is a conical surface, and the cone angle of the transition surface 1015 is generally 90 ° to 150 °, so that the included angle between the transition surface 1015 and the axial cross-section of the wall surfaces of the first diversion cavity 1013 and the first sound outlet cavity 1014 is an obtuse angle, the transition is smoother, and the sound energy loss is further reduced. In addition, a fillet can be arranged at the transition part of the transition surface 1015 and the first diversion cavity 1013 and the first sound outlet cavity 1014, and the radius of the fillet is 1/10 to 1/4 of the diameter of the cross section of the first diversion cavity 1013 or the first sound outlet cavity 1014, so that when sound passes through, the sound is smoothly transmitted, the energy loss is less, and the good sound quality of the earphone is ensured. Similarly, the transition surface 1015 between the second guide chamber 1023 and the second sound outlet chamber 1024 is also a conical surface with a cone angle of 90 ° to 150 °, and the cone angle of the transition surface 1015 between the second guide chamber 1023 and the second sound outlet chamber 1024 is not greater than the cone angle of the transition angle between the first guide chamber 1013 and the first sound outlet chamber 1014, so that the sound cavity channel gradually decreases or remains unchanged when passing through the sound cavity of the first voice coil. In practical application of the present invention, the transition surface 1015 may be a trumpet-shaped curved surface, a volute-shaped curved surface, or the like, that is, the transition surface 1015 may make the transition between the first guiding cavity 1013 and the first sound outlet cavity 1014 smoother, or make the transition between the second guiding cavity 1023 and the second sound outlet cavity 1024 smoother, so that the sound can pass through conveniently, and the sound quality is ensured.

In general, the moving coil with middle and low frequency is larger than the moving coil with high frequency, so the first moving coil 2 is usually set as the middle and low frequency moving coil, and the second moving coil 3 is set as the high frequency moving coil.
