[0027] For ease of understanding, the relevant technical terms involved in the embodiments of the present application are explained and described below.

[0028] T-iron, also called electrical iron, is made of pure iron. It is a component of the sound component. In the sound component, the main function of T-iron is to conduct magnetism when powered on, but it has no residual magnetism. When the speaker is powered off, the magnetic field disappears and its magnetism disappears immediately. Therefore, the purity of T-iron will directly affect the working efficiency of the sound component and some important parameters of nonlinear distortion.

[0029] U iron plays a magnetic conductive role in the magnetic circuit assembly and is a component of the sound component. U iron is pure iron and has no residual magnetism.

[0030] The voice coil is directly defined as the coil through which current flows in the speaker. It is an important part of the mechanical wave system of the electric speaker and can be said to be the heart of the speaker. The performance of the voice coil will affect the sound intensity characteristics, sound intensity level, impedance curve, distortion, transient characteristics, speaker parameters, sound quality, etc. of the speaker, especially the power handling and life of the speaker.

[0031] Washers, in the magnetic circuit components, washers, U irons and T irons all play a role in magnetic conductivity. They can concentrate the N pole and S pole of the magnet to the gap through the loop, so that the gap produces a stronger magnetic field. The winding width of the voice coil is just located in the middle of the gap, so the inner diameter and thickness of the iron sheet are very important.

[0032] The elastic wave, also known as the centering support, is an important part of the speaker system. The elastic wave's correlation coefficient has a certain influence on the speaker. The elastic wave has the following functions: to keep the voice coil in the electromagnetic system in the correct position in the magnetic gap; to ensure that the electromagnetic system reciprocates along the axial direction when the voice coil is subjected to force; to determine the efficiency of the speaker together with the mechanical wave system; and to prevent dust from entering the magnetic gap.

[0033] The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings. The directional terms mentioned in the embodiments of the present application, such as "upper", "lower", "front", "back", "left", "right", "inner", "outer", "side", "top", "bottom", etc., are only referenced to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application.

[0034] Loudspeakers are widely used. Loudspeakers generally include a first sound unit and a second sound unit. The first sound unit produces low-frequency sound, and the second sound unit produces medium- and high-frequency sound. However, since the vibration mass of the vibration system of the first sound unit in the prior art is relatively small, the lower limit of the frequency response of the first sound unit is relatively high, that is, the low-frequency diving ability is relatively weak, resulting in the first sound unit not having a good hearing experience in the low-frequency band.

The frequency modulation component 3 may abut against the first coil 22 along the thickness direction of the first diaphragm 24, so that the weight of the frequency modulation component 3 may act on the first coil 22. The first coil 22 can be used to cut the magnetic flux lines in the magnetic field generated by the first magnet 212, and can drive the first diaphragm 24 and the frequency modulation component 3 to vibrate along the thickness direction of the first diaphragm 24. Since the weight of the frequency modulation component 3 can act on the first coil 22 along the thickness direction of the first diaphragm 24, the vibration mass of the first coil 22 can be increased, that is, the frequency modulation component 3 can increase the resistance that the first coil 22 needs to overcome when cutting the magnetic flux lines, thereby reducing the lower limit of the frequency response of the first sound component, that is, improving the low-frequency diving ability of the first sound component, so that the speaker has a better listening experience in the low-frequency band.

Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this can make the matching structure of the first sound element 2 and the second sound element 4 simple and effective, which is beneficial to increase the vibration mass of the vibration system of the first sound element 2, and the lower limit of the frequency response of the first sound element can be reduced, thereby making the speaker have a better listening experience in the low frequency band.

[0049] In a possible implementation, the resonance frequency of the first sounding member 2 may be in the range of 50 Hz to 100 Hz. By making the resonance frequency of the first sounding member 2 in the range of 50 Hz to 100 Hz, compared with the resonance frequency of the first sounding unit in the prior art in the range of 80 Hz to 150 Hz, this can ensure the low-frequency diving ability of the first sounding member 2, thereby making the speaker 1 have a better sense of hearing in the low frequency band.

[0050] By adopting the loudspeaker 1 proposed in the present application, the vibration mass of the vibration system of the first sound-emitting component 2 can be increased, and the lower limit of the frequency response of the first sound-emitting component 2 can be reduced, that is, the low-frequency diving ability of the first sound-emitting component 2 can be improved, so that the loudspeaker 1 can have a better listening experience in the low-frequency band.

[0051] The above describes the detailed structure of the speaker 1 proposed in the present application. Next, the application of the speaker 1 in conjunction with the vehicle 10 will be introduced.

[0052] Figure 6 FIG. 1 is a schematic diagram of a speaker 1 according to an embodiment of the present application being applied to a vehicle 10. Figure 6 The vehicle 10 may include a vehicle body 101, a box 102, and a speaker 1, wherein the box 102 may be connected to the vehicle body 101, and the speaker 1 may be disposed in the box 102. By arranging the vehicle body 101, the box 102, and the speaker 1 having better low-frequency diving capability in the vehicle 10, wherein the box 102 may be connected to the vehicle body 101, and the speaker 1 may be disposed in the box 102, the user of the vehicle 10 may have a better sense of hearing in the low-frequency band sound of the speaker 1.
