As shown in Fig. 1-8, an earphone is provided, comprising: a shell 1, wherein the shell 1 has an installation space, and the shell 1 is provided with a sound outlet 2; a speaker assembly 3, wherein the speaker assembly 3 is arranged above the sound outlet 2; a resonance assembly 4, wherein the resonance assembly 4 is arranged above the speaker assembly 3, and the resonance assembly 4, the speaker assembly 3 and the sound outlet 2 form a cavity; wherein the airflow generated by the sound of the speaker assembly 3 causes the resonance assembly 4 to resonate to improve the low-frequency effect.

In the above technical solution, the earphones can be wired earphones or wireless earphones, etc., and the shell 1 is a mounting shell. When there are one earphone on each side, the shell 1 is two independent shells 1. When there is only one earphone, such as a neck-hanging earphone, the shell 1 can be an integral structure. The speaker assembly 3 is a sound-generating assembly. The speaker assembly 3 includes but is not limited to diaphragms, voice coils, magnets, brackets and other components. It is not an improvement point of the present technical solution and will not be described in detail. Among them, the resonance assembly 4 can be a single component or formed by connecting multiple components. The resonance assembly 4 is placed above the speaker assembly 3, and the sound outlet 2 is placed below the speaker assembly 3. The resonance assembly 4, the speaker assembly 3 and the shell 1 are used to form a cavity, as shown in Figures 9-10. When in use, the vibrating airflow generated by the speaker assembly 3 during the sound generation process is transmitted to the position of the resonance assembly 4, causing the resonance assembly 4 to resonate at a low frequency, thereby improving the low-frequency effect and improving the sound quality.

Referring to Figure 4, the installation space is provided with an upwardly opening installation groove 5, the installation groove 5 is arranged at the position of the sound outlet 2, the speaker assembly 3 is placed in the installation groove 5, the resonance assembly 4 is arranged at the opening position of the installation groove 5, and the resonance assembly 4, the installation groove 5 and the speaker assembly 3 form a cavity.

In order to facilitate the resonance component 4, the mounting groove 5 and the speaker component 3 to form a cavity, the mounting groove 5 is set inside the shell 1. The mounting groove 5 is a protrusion with a hollow structure. At the same time, the sound hole 2 is set at the bottom of the mounting groove 5, the speaker component 3 is set in the mounting groove 5, and the resonance component 4 is set at the top of the mounting groove 5. The resonance component 4, the mounting groove 5 and the speaker component 3 form a cavity for easy installation.

5-8 , the resonance component 4 includes a resonance membrane 6 , and the resonance membrane 6 , the speaker component 3 , and the sound outlet 2 form a cavity.

In one embodiment, the resonance component 4 can be implemented using a single resonance membrane 6, and a fold ring is set at the edge of the resonance membrane 6 to facilitate the forward and backward movement of the resonance membrane 6 to form resonance, thereby enhancing the low-frequency effect and improving the sound quality.

Furthermore, the resonance assembly 4 includes a tuning net 7 for exhausting excess airflow, an opening is provided on the resonance membrane 6, and the tuning net 7 is arranged at the opening position.

In a preferred embodiment, the resonance component 4 also includes a tuning net 7, and an opening is set in the middle position of the resonance membrane 6. The opening can be a circular hole shape or other shapes. The tuning net 7 is set at the opening position. When the air flow generated by the speaker component 3 is too large, the resonance of the resonance component 4 is likely to damage the timbre. In this regard, the tuning net 7 is set to discharge excess air flow, thereby ensuring the sound quality.

Preferably, the resonance component 4 comprises a sheet 8 , wherein the sheet 8 is mounted on the resonance membrane 6 , and an opening is provided on the sheet 8 ; wherein excess airflow is discharged from the opening of the sheet 8 through the tuning net 7 .

The resonance component 4 may also include a sheet 8, wherein the sheet 8 is in the form of a ring. The sheet 8 is used to prevent the vibration of the resonance membrane 6 during the medium and high frequencies from damaging the sound quality. For this purpose, the sheet 8 is added to the resonance membrane 6 to ensure that the medium and high frequency resonance membrane 6 does not vibrate and ensure the cleanliness of the sound.

During the installation process, the edge of the resonance membrane 6 is connected and fixed to the installation groove 5 by glue, the sheet 8 is installed on the resonance membrane 6 by glue, and the tuning net 7 is adhered to the sheet 8 by its own double-sided adhesive. The resonance membrane 6 is made of soft rubber material, such as PU and silicone rubber, and the sound can be changed by changing different materials. The tuning net 7 is made of nylon material, and the sheet 8 is made of hard material, such as acrylic or stainless steel, which effectively ensures that the resonance membrane 6 does not vibrate at medium and high frequencies, thereby ensuring the purity of the sound.

When in use, the sound is a sine wave. When the electrical signal is at a peak, the diaphragm of the speaker assembly 3 is pushed forward, driving the airflow in the rear cavity to inhale air, and at the same time driving the resonance membrane 6 to vibrate forward, which is superimposed on the sound signal generated by the speaker diaphragm to make the low frequency better. The sound is a sine wave. When the electrical signal is at a trough, the speaker diaphragm is pushed backward, driving the airflow in the rear cavity to exhaust air outward, and at the same time driving the resonance membrane 6 to vibrate backward, which is superimposed on the sound signal generated by the speaker diaphragm to make the low frequency better.

The earphone comprises a control panel 9, which is arranged in the housing 1 and is used for outputting and receiving signals.

The headset includes a battery 10 electrically connected to the control board 9 , and the housing 1 is provided with a charging contact 11 electrically connected to the battery 10 , and the charging contact 11 is used to charge the battery 10 .
