[0002] The headphone speaker is a key component inside the headset. It converts electrical signals into sound signals, enabling users to hear music, voice or other audio content. The working principle and structural design of the headphone speaker are crucial to the sound quality, volume and overall listening experience. In order to enable each unit to focus on audio processing in a specific frequency band, thereby providing clearer and more delicate sound performance and avoiding the limitation of a single dynamic coil that is difficult to take into account the entire frequency band, a dual dynamic coil system three-cavity damped reverberation structure speaker is required.

[0003] When using traditional headphone speakers, the electrical signal output by the sound source device is transmitted to the inside of the headphone speaker through the headphone cable. After the electrical signal enters the dynamic unit, an electromagnetic force is generated in the magnetic field around the dynamic coil. This force drives the dynamic coil to vibrate. The dynamic coil is connected to a thin and light diaphragm. When the dynamic coil vibrates, the diaphragm also vibrates. The vibration of the diaphragm causes compression and rarefaction of the air, generating sound waves.

[0004] However, the problem that the existing headphone speakers have a single-vibration system single-cavity structure or a dual-vibration system single-cavity structure and cannot effectively improve the low-frequency performance of the speaker by mixing multiple cavities, thus affecting the low-frequency performance of the headphone speakers. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a dual dynamic system three-cavity damping reverberation structure speaker, which aims to improve the existing headphone speakers with a single vibration system single cavity or a dual vibration system single cavity structure, and cannot effectively improve the low-frequency performance of the speaker by mixing multiple cavities.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a double dynamic system three-cavity damped reverberation structure speaker, including a shell, a bracket one is fixedly connected to the inside of the shell, a vibration system one is arranged between the shell and the bracket one, a vibration system two is arranged inside the shell, a cavity one is arranged between the shell and the bracket one, a bracket two is fixedly connected to the inside of the shell, a cavity two is arranged between the bracket two and the bracket one, and a cavity three is arranged inside the shell.

[0007] As a further description of the above technical solution:

[0008] A magnet is fixedly connected inside the vibration system, a fixing ring is fixedly connected inside the shell, a diaphragm is fixedly connected to one side of the fixing ring, a paper cone is fixedly connected to one side of the diaphragm, a coil is fixedly connected to the bottom of the paper cone, and the outer wall of the coil is slidably connected between the magnet and the bracket.

[0011] As a further description of the above technical solution:

[0012] Pins are fixedly connected inside the shell.

[0013] The utility model has the following beneficial effects:

[0014] In the utility model, when the speaker vibrates, the vibration is first transmitted from the built-in cavity one to the cavity two, thereby increasing the volume of the sound cavity, and then transmitted from the cavity two to the cavity three, thereby increasing the volume of air pushed by the speaker again, and the bass effect is further improved, thereby achieving the effect of increasing the overall bass performance of the speaker, and achieving the effect of improving the low-frequency performance of the earphone, solving the problem that the existing earphone speakers are single-vibration system single-cavity or double-vibration system single-cavity structure, and cannot effectively improve the low-frequency performance of the speaker by mixing multiple cavities, thereby improving the low-frequency performance of the earphone speakers.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Reference Figure 1-Figure 3 The utility model provides an embodiment: a double dynamic system three-cavity damping reverberation structure speaker, including a shell 1, a bracket 3 is fixedly connected inside the shell 1, a vibration system 2 is arranged between the shell 1 and the bracket 3, a vibration system 2 9 is arranged inside the shell 1, a cavity 16 is arranged between the shell 1 and the bracket 3, a bracket 2 15 is fixedly connected inside the shell 1, a cavity 2 17 is arranged between the bracket 2 15 and the bracket 3, a cavity 3 18 is arranged inside the shell 1, a magnet 4 is fixedly connected inside the vibration system 2, a fixing ring 5 is fixedly connected inside the shell 1, and one side of the fixing ring 5 A diaphragm 16 is fixedly connected, a paper cone 17 is fixedly connected to one side of the diaphragm 16, a coil 18 is fixedly connected to the bottom of the paper cone 17, the outer wall of the coil 8 is slidably connected between the magnet 14 and the bracket 13, a magnet 2 10 is fixedly connected inside the vibration system 29, a fixing ring 2 11 is fixedly connected inside the vibration system 29, a diaphragm 2 12 is fixedly connected to one side of the fixing ring 2 11, a paper cone 2 13 is fixedly connected to one side of the diaphragm 2 12, a coil 2 14 is fixedly connected between the diaphragm 2 12 and the paper cone 2 13, the coil 2 14 is slidably connected between the housing 1 and the magnet 2 10, and a pin 19 is fixedly connected inside the housing 1;

[0022] Specifically, first, pin 19 is connected to an electrical signal, and then the driving coil 8 starts working. The coil 8 is suspended and vibrated in the magnet 4 to form a stable and sensitive electromagnetic field reaction. The coil 8 is connected to the paper cone 7 through the diaphragm 6 to ensure coordination and consistency when transmitting vibration. As the electrical signal changes, the coil 8 drives the diaphragm 6 to vibrate, and the vibration of the diaphragm 6 is transmitted to the paper cone 7. The coordinated vibration of the paper cone 7 and the diaphragm 6 produces sound in the cavity 16, and the vibration waveform is transmitted to the cavity 2 17 through the cavity 16. The design of the cavity 2 17 further increases the volume of the sound cavity, so that the sound waves propagate in a larger space, thereby enhancing the resonance effect of the sound. This process not only expands the physical volume of the sound cavity, but also enhances the depth and fullness of the sound. Finally, the sound waves are transmitted from the cavity 2 17 to the cavity 3 18, which significantly enhances the bass effect by further increasing the volume of air pushed by the speaker. The unique design and optimized structure of the cavity 3 18 make the low-frequency sound fuller and stronger, providing excellent bass performance.

[0023] Working principle: When using the double dynamic system three-cavity damping reverberation structure speaker, firstly, the pin 19 is connected to the electrical signal, and then the coil 8 is driven to make the coil 8 suspend and vibrate in the magnet 4. The coil 8 is connected to the paper cone 7 through the diaphragm 6. Therefore, the cavity 16 generated by the coordinated vibration of the paper cone 7 and the diaphragm 6 is transmitted to the cavity 2 17, thereby increasing the volume of the sound cavity, and then transmitted from the cavity 2 17 to the cavity 3 18, thereby increasing the volume of the air pushed by the speaker again, and the bass effect is further improved.

[0024] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
