[0027] Embodiment 1

[0028] like Figure 1-Figure 2 As shown, an embodiment of the utility model provides an earphone assembly, including a shell 1 and a PZT transducer 2, the shell 1 is provided with a mounting groove 11, a boss 12 is provided in the mounting groove 11, the surface of the boss 12 constitutes a supporting plane, the mounting groove 11 is divided into an upper groove area 111 and a lower groove area 112 by the supporting plane in the vertical direction, the area of ​​the lower groove area 112 except the area where the boss 12 is located is a vacant space, the PZT transducer 2 is arranged in the upper groove area 111, and at least a part of the area of ​​the PZT transducer 2 is in contact with the surface of the boss 12; at least a part of the area of ​​the PZT transducer 2 corresponds to the vacant space, so that the area corresponding to the vacant space is in a suspended state.

[0029] By utilizing the boss 12 structure, after the PZT transducer 2 is installed, the area at the bottom of the PZT transducer 2 that is not in contact with the boss 12 is in a suspended state, thereby effectively eliminating unnatural auditory sensations such as mechanical sound and burrs when the PZT transducer 2 vibrates, improving the sound texture, and thus improving the user's auditory experience.

[0030] The boss 12 extends from one or more sides of the groove wall of the mounting groove 11 to the center of the mounting groove 11. Such a design allows the boss 12 to more firmly support the PZT transducer 2. Since the boss 12 extends from the groove wall of the mounting groove 11, the structure is more stable, which can effectively prevent the PZT transducer 2 from being displaced or loosened due to vibration during use.

[0031] like Figure 1 As shown, in this embodiment, two bosses 12 are arranged on opposite sides of the groove wall of the mounting groove 11 extending toward the center of the mounting groove 11, and the empty space extends from the center of the lower groove area 112 to the periphery, that is, the empty space is located between the two bosses 12. Such a design can provide more uniform support for the PZT transducer 2, so that the PZT transducer 2 is more evenly stressed during operation, and deformation and damage caused by uneven support can be reduced.

[0032] In this embodiment, the two bosses 12 have the same shape and are symmetrically arranged along the center of the mounting groove 11. The empty space between the two bosses 12 is roughly circular with two opposite openings. Of course, in other embodiments, the shape of the boss 12 and the empty space can also be other shapes.

[0033] It should be noted that the boss 12 can be integrally formed with the housing 1 , or can be a component independent of the housing 1 , and when in use, fixedly installed in the mounting groove 11 .

[0034] It should also be noted that the bottom of the boss 12 may be in direct contact with the bottom of the mounting groove 11 or may not be in direct contact with the bottom of the mounting groove 11 .

[0035] The support plane is a horizontal plane. This design can provide a flat and stable support plane for the PZT transducer 2, ensuring that the PZT transducer 2 can remain horizontal and stable after installation, and its working performance will not be affected by tilting. It can also avoid local stress concentration caused by tilting or uneven support, thereby reducing the risk of deformation and damage of the PZT transducer 2 and extending its service life.

[0036] The area of ​​the boss 12 in the lower groove area 112 is smaller than the area of ​​the vacated space. With this design, the large vacated space can give full play to the vibration reduction function, especially reduce the vibration transmitted to the earphone housing 1, reduce mechanical noise, and improve the sound quality of the earphone. At the same time, the large vacated space can make the suspended area of ​​the PZT transducer 2 have greater freedom when vibrating, producing a purer and more natural sound. Furthermore, it can provide a larger space for heat dissipation, help the heat generated by the PZT transducer 2 during work to dissipate more quickly, prevent overheating, and increase service life.

[0037] The groove wall of the upper groove area 111 is provided with one or more limiting connection parts 1111, and the limiting connection parts 1111 are used as the parts connected with the PZT transducer 2, and the limiting connection parts 1111 are formed by extending from the groove wall of the upper groove area 111 to the center of the upper groove area 111. The limiting connection parts 1111 are connected to the PZT transducer 2 instead of the entire groove wall of the upper groove area 111 and the PZT transducer 2, so that a spacing space is formed in most areas between the PZT transducer 2 and the groove wall of the upper groove area 111, so that the PZT transducer 2 can fully vibrate and release energy.

[0038] In this embodiment, four limiting connection parts 1111 are arranged. Such a design can ensure the stability of the PZT transducer 2 after connection while allowing the PZT transducer 2 to vibrate and release energy more fully.

[0039] The PZT transducer 2 is bonded to the limiting connection portion 1111 , for example, by glue, which is not only convenient for installation but also low in cost.

[0040] Embodiment 2

[0041] like Figure 1-Figure 2 As shown, an embodiment of the utility model further provides an earphone, comprising the above-mentioned earphone assembly, wherein the above-mentioned shell 1 serves as an earphone back cover, that is, the PZT transducer 2 is installed on the earphone back cover.

[0042] It should be noted that, except for the above-mentioned earphone assembly structure, the rest of the structure of the earphone can be the same as that in the prior art, and will not be described in detail here.

[0043] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
