[0043] The present invention provides an earplug assembly 100 , which is applied to a headphone 1000 .

[0044] Reference Figures 1 to 5 In an embodiment of the present invention, the earplug assembly 100 includes an earphone shell 10, a support frame 20, a speaker 30 and a sound cavity cover 40, the earphone shell 10 is provided with a accommodating cavity 12 having an opening 11; the support frame 20 is connected to the earphone shell 10 and covers the opening 11, and the support frame 20 is provided with a sound outlet 21; the speaker 30 is connected to the support frame 20 and is located in the accommodating cavity 12; the sound cavity cover 40 is located in the accommodating cavity 12, and is enclosed with the support frame 20 to form a sound cavity 40a, and the sound outlet 21 is connected to the sound cavity 40a.

[0045] The earphone shell 10 and the support frame 20 can be made of plastic, which can be injection molded to have high structural strength and be easy to process. The earphone shell 10 is formed with a receiving cavity 12, and the speaker 30 can be installed in the receiving cavity 12 through the opening 11 to improve the overall aesthetics of the earplug assembly 100. The support frame 20 can be specifically connected to the earphone shell 10 by snap-fit ​​connection to cover the opening 11, which can not only improve the efficiency of early installation and later maintenance and disassembly, but also block the opening 11 through the support frame 20, thereby protecting the electrical components in the receiving cavity 12 and ensuring the normal service life of the earplug assembly 100. A plurality of sound outlet holes 21 can be provided on the support frame 20, and the plurality of sound outlet holes 21 are arranged at intervals, so that the output volume of the speaker 30 can be increased to increase the sound effect of the earplug assembly 100.

[0046] In addition, in order to increase functionality, the earplug assembly 100 may also include a microphone 80, which is an energy conversion device that converts sound signals into electrical signals, is used to pick up sound, and can realize the audio receiving function, thereby realizing the interactive processing of audio signals. The microphone 80 is arranged on the outside of one of the earphone shells 10, and extends a distance from the outer side of the earphone shell 10 through a connecting rod. The end of the connecting rod is provided with a sound hole corresponding to the position of the microphone 80, so that the microphone 80 is directly facing the user's mouth, thereby improving the pickup efficiency.

[0047] The earplug assembly 100 of the technical solution of the present invention is applied to a headphone 1000, and the earplug assembly 100 includes an earphone shell 10 and a support frame 20, the earphone shell 10 is provided with a receiving cavity 12 having an opening 11, and the support frame 20 is connected to the earphone shell 10 and covers the opening 11. At the same time, the earplug assembly 100 also includes a speaker 30 and a sound cavity cover 40, the speaker 30 is connected to the support frame 20 and is located in the receiving cavity 12, and the sound cavity cover 40 is located in the receiving cavity 12 and encloses the support frame 20 to form a sound cavity 40a, and the sound outlet hole 21 of the support frame 20 is connected to the sound cavity 40a. In this way, a sound cavity 40a is formed by enclosing the sound cavity cover 40 and the support frame 20. When the speaker 30 is working, the sound emitted by the speaker 30 toward the sound cavity 40a will be blocked by the sound cavity cover 40, and after being reflected by the sound cavity cover 40, it will be conducted in the direction of the sound outlet 21, thereby making the sound emitted by the speaker 30 diffuse in the direction of the sound outlet 21, so as to increase the sound effect of the sound outlet 21 of the earplug assembly 100, improve the sound quality of the earplug assembly 100, enhance the somatosensory vibration effect, enhance the usability of the earplug assembly 100, and effectively improve the user experience.

[0048] In one embodiment of the present application, in combination with reference Figure 3 , Figure 7 as well as Fig. 9The surface of the support frame 20 facing the accommodating cavity 12 is concavely provided with a mounting groove 22, the speaker 30 is embedded in the mounting groove 22, and the sound cavity cover 40 covers the notch of the mounting groove 22 to form the sound cavity 40a. The mounting groove 22 is formed on the support frame 20 to facilitate the positioning and installation of the speaker 30, thereby improving the accuracy and efficiency of the installation. At the same time, after the speaker 30 is embedded in the mounting groove 22, the circumferential side wall of the speaker 30 is abutted against the inner wall surface of the mounting groove 22 to ensure the stability of the speaker 30 after installation, thereby preventing the speaker 30 from shaking during operation and affecting the sound quality. The sound outlet 21 is connected to the bottom surface of the mounting groove 22. The sound cavity cover 40 covers the slot of the mounting slot 22 to enclose a sound cavity 40a, so that the speaker 30 is completely accommodated in the sound cavity 40a. This ensures that the sound emitted by the speaker 30 is diffused toward the sound outlet 21 to increase the sound effect of the sound outlet 21 of the earplug assembly 100.

[0049] In one embodiment of the present application, refer to Figure 4 and Figure 7 , the sound cavity cover 40 is detachably connected to the support frame 20. It can be understood that the sound cavity cover 40 can be connected to the support frame 20 by a detachable connection method such as a snap or threaded connection, so that the operator can install or remove the sound cavity cover 40 and improve the operation efficiency. Specifically, an external thread can be formed on the outer wall periphery of the sound cavity cover 40, and an internal thread can be formed on the inner wall surface of the mounting groove 22 of the support frame 20. Through the connection and cooperation of the external thread and the internal thread, not only can the sound cavity cover 40 be connected and fixed to the support frame 20, but also the sealing of the connection between the sound cavity cover 40 and the support frame 20 can be improved, so as to prevent the sound emitted by the speaker 30 from leaking from the connection between the sound cavity cover 40 and the support frame 20. In addition, the earplug assembly 100 can also be provided with a sealing member, which is clamped by the sound cavity cover 40 and the support frame 20 to further seal the sound cavity 40a, thereby further preventing the sound emitted by the speaker 30 from leaking from the connection between the sound cavity cover 40 and the support frame 20. It is understandable that the sealing component can be made of elastic materials such as plastic, silicone, or rubber, so the sound cavity cover 40 can press the side wall of the sealing component to form appropriate bending and deformation, thereby ensuring that the barrier achieves a better effect.

[0050] In one embodiment of the present application, refer to Figures 2 to 7, the earplug assembly 100 also includes a vibration motor 50 and a main control board 60, the main control board 60 is electrically connected to the speaker 30 and the vibration motor 50 respectively, the vibration motor 50 is connected to the support frame 20 and is located in the accommodating cavity 12, and the main control board 60 is connected to the sound cavity cover 40 and is located in the accommodating cavity 12. Among them, the main control board 60 is electrically connected to the speaker 30 and the vibration motor 50 respectively, so that the main control board 60 can select to output the corresponding heavy bass signal to the speaker 30 and the vibration motor 50 according to the received control signal to control, so as to improve the user's heavy bass feeling and meet the user's needs. In addition, the vibration motor 50 is connected to the support frame 20, and can be located on the same surface of the support frame 20 with the sound cavity cover 40, so that it is not only convenient for operators to install and improve installation efficiency, but also makes the vibration motor 50 closer to the human ear, so that users can more easily get the vibration feeling and improve the use experience. The main control board 60 is connected to the sound cavity cover 40 and is arranged away from the vibration motor 50, so that the vibration of the vibration motor 50 can be prevented from affecting the normal operation of the main control board 60. The vibration motor 50 and the main control board 60 are both located in the accommodating cavity 12, so that the vibration motor 50 and the main control board 60 are electrically connected and can effectively protect the vibration motor 50 and the main control board 60.

[0051] Furthermore, in conjunction with reference Figure 8 The surface of the sound cavity cover 40 facing the vibration motor 50 is concavely formed with an avoidance groove 41, and part of the vibration motor 50 is accommodated in the avoidance groove 41. Among them, by allowing part of the vibration motor 50 to be accommodated in the avoidance groove 41 of the sound cavity cover 40, the sound cavity cover 40 and the vibration motor 50 can be installed and matched more compactly, thereby avoiding the overall structure volume of the earplug assembly 100 being too large. It should be noted that there is a certain gap between the vibration motor 50 and the groove wall of the avoidance groove 41 of the sound cavity cover 40, so as to avoid the vibration motor 50 from hitting the sound cavity cover 40 when vibrating, so as to ensure the normal service life of the vibration motor 50 and the sound cavity cover 40.

[0052] Furthermore, the sound cavity cover 40 is arranged in an arc-shaped surface on the groove wall surface of the avoidance groove 41; it can be understood that the groove wall surface of the sound cavity cover 40 is arranged in an arc-shaped surface, which can not only prevent the operator from being easily cut by the sharp end surface during installation, thereby improving the safety during installation, but also facilitate the operator to hold and install, and make the sound cavity cover 40 more beautiful as a whole.

[0053] Optionally, the main control board 60 is connected to the surface of the sound cavity cover 40 facing away from the support frame 20, and the surface of the sound cavity cover 40 facing away from the support frame 20 is arranged in a plane; wherein, in order to prevent the main control board 60 from being affected by the vibration of the vibration motor 50, the main control board 60 can be connected and fixed to the surface of the cavity cover facing away from the support frame 20, and by making the surface of the cavity cover facing away from the support frame 20 in a plane, the main control board 60 can be placed on the sound cavity cover 40 more stably, thereby further improving the stability of the main control board 60 after installation, thereby ensuring the normal operation of the main control board 60.

[0054] Optionally, the circumferential outer wall of the sound cavity cover 40 is provided with anti-skid protrusions (not shown). Specifically, in order to prevent the operator from losing his hands when installing the sound cavity cover 40, anti-skid protrusions are provided on the circumferential outer wall of the sound cavity cover 40, thereby increasing the friction between the operator and the sound cavity cover 40, and the anti-skid protrusions can be arranged in a strip shape or in a dot shape, so that the operator is not easy to lose his hands and is more labor-saving during operation. Specifically, the number and size of the anti-skid protrusions can also be set according to the specific size of the sound cavity cover 40, which will not be elaborated here.

[0055] In one embodiment of the present application, refer to Fig. 9 and Fig.10 The support frame 20 is provided with two limiting protrusions 23 on the surface facing the accommodating cavity 12, and each limiting protrusion 23 is provided with a limiting groove 231. The vibration motor 50 is provided with two limiting blocks 51, and one limiting block 51 is embedded in the limiting groove 231 of one limiting protrusion 23, so that the vibration motor 50 is fixed to the support frame 20. The two limiting blocks 51 are arranged at the two opposite ends of the vibration motor 50, so that the overall force of the vibration motor 50 is balanced after installation and fixation. By providing the limiting grooves 231 on the two limiting protrusions 23, the two limiting blocks 51 are conveniently installed and positioned, and the installation efficiency is improved. The limiting grooves 231 can effectively limit and abut the limiting blocks 51, so as to prevent the vibration motor 50 from being separated from the limiting protrusion 23 after the vibration process, so as to ensure the normal operation of the vibration motor 50. In addition, the limiting block 51 is provided with a first threaded hole 511, and the limiting protrusion 23 is provided with a second threaded hole 232. The earplug assembly 100 is further provided with a connecting screw, which passes through the first threaded hole 511 and the second threaded hole 232 in sequence to further fix the limiting block 51 to the limiting protrusion 23. It should be noted that the number of the limiting block 51 and the limiting protrusion 23 can be set to multiple, which can also further improve the stability of the vibration motor 50 after installation. The specific number can be selected by those skilled in the art and will not be elaborated here.

[0056] In one embodiment of the present application, in combination with reference Figure 6, the number of the vibration motors 50 is multiple, and the multiple vibration motors 50 are connected to the surface of the support frame 20 facing the accommodating cavity 12, and are arranged at intervals along the circumference of the speaker 30. Among them, the number of the vibration motors 50 is multiple, which can further improve the sound effect of the earplug assembly 100, and the multiple vibration motors 50 are connected to the surface of the support frame 20 facing the accommodating cavity 12, and are arranged at intervals along the circumference of the speaker 30, so that the overall force of the earplug assembly 100 is balanced, and the user also obtains the same vibration feeling from multiple directions, thereby improving the user's experience. It can be understood that when there are multiple vibration motors 50, the sound cavity cover 40 is formed with a corresponding avoidance groove 41 corresponding to each vibration motor 50, so that the internal components of the earplug assembly 100 can be assembled more compactly, so as to effectively utilize the internal space of the earplug assembly 100.

[0057] In one embodiment of the present application, in combination with reference Figure 1 and Figure 4 The earphone shell 10 also includes an earplug pad 70, which is detachably connected to the side of the support frame 20 away from the earphone shell 10. For comfort, each earplug component may also include an earplug pad 70, which is installed on the inner surface of the earphone shell 10. The inner surface of the earphone shell 10 refers to the surface facing the other earphone shell 10, and its material may be sponge, silicone or rubber, etc., which is soft. The earplug pad 70 is in direct contact with the user's ear, avoiding the hard earphone shell 10 from contacting the human body, thereby reducing the pressure on the human ear, and can reduce the vibration energy of the audio to a certain extent, thereby increasing protection.

[0058] The present invention also proposes a headset 1000, which includes a connecting component 200 and an earplug component 100, wherein the two earplug components 100 are respectively connected to the connecting component 200, and the specific structure of the earplug component 100 refers to the above embodiment. Since the headset 1000 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. Among them, the connecting component 200 connects two earphone shells 10, and the connection method between the connecting component 200 and the two earphone shells 10 can be threaded connection, plug-in connection or snap connection, etc., which is not limited here.
