Technical Field

[0001] This utility model relates to the technical field of multimedia equipment, and more specifically, to a microphone head structure. Background Technology

[0002] A microphone, also known as a transducer, is an energy conversion device that converts sound signals into electrical signals. The name comes from the English word "microphone." It is also called a microphone or microphone. In the 20th century, microphones evolved from initially using resistance to convert sound to electricity to inductive and capacitive conversion. Many new microphone technologies gradually developed, including ribbon microphones, dynamic microphones, and the currently widely used condenser and electret microphones. Existing microphone cap structures are complex, with inefficient internal layouts, numerous components, and time-consuming and laborious installation. Therefore, there is an urgent need to design a microphone cap structure that is simple in structure and easy to install. Utility Model Content

[0005] Furthermore, the housing is conical in shape, with several positioning posts at the bottom of the housing, and several mounting holes are opened around the first base.

[0006] Furthermore, the first base has a protruding ring, which forms a snap-fit ​​portion facing outwards, and the second base has an annular engagement groove.

[0007] Furthermore, the housing is further provided with several support tubes, which are connected to the housing.

[0008] Furthermore, the housing further includes a cover, and both the housing and the cover have through holes.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0022] Example

[0023] Reference Figure 1-3 As shown, this utility model discloses a microphone head structure, including a housing 10, in which a first base 101 is installed. The first base 101 is annular. Specifically, the housing 10 is conical. Several positioning posts 105 are provided at the bottom of the housing 10. Several mounting holes 1011 are opened around the first base 101. Bolts pass through the mounting holes 1011 and lock the first base 101 at the conical bottom of the housing 10.

[0024] Reference Figure 4-5 As shown, the first base 101 is fitted with the second base 102 via a snap-fit ​​mechanism. Specifically, the first base 101 has a protruding ring forming a snap-fit ​​portion 1012 facing outwards. The second base 102 has an annular engaging groove 1021. When the first base 101 is inserted into the annular first base 101, the engaging groove 1021 and the snap-fit ​​portion 1012 work together to quickly snap the first base 101 into place. The second base 102 has a cavity in which a microphone core 103 is embedded. A square hole is formed at the bottom of the cavity. The microphone core 103 is inserted into the cavity, and the microphone core 103 and the cavity are fitted with an interference fit to fix the microphone core 103 in place within the cavity of the second base 102. The square hole at the bottom of the cavity is for connecting the microphone core 103 to an electrical wire.

[0025] Reference Figure 1-3 As shown, the housing 10 is further provided with several support tubes 106, which are connected to the housing 10. Specifically, one end of the support tube 106 is connected to the housing 10 and the other end is connected to a fixed bracket (not shown in the figure). The wire can pass through the support tube 106 into the housing 10 and then be electrically connected to the microphone core 103 through the square hole. This design is compact and has a reasonable layout.

[0026] In addition, the housing 10 further includes a cover 104. Both the housing 10 and the cover 104 have through holes. The cover 104 covers the microphone core 103, the first base 101 and the second base 102, and plays a protective role. The through holes of the cover 104 and the housing 10 are used for sound transmission and heat dissipation.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
