Referring to fig. 1 and fig. 2 together, a microphone according to a first embodiment of the present application will be described. The microphone includes a microphone tube 10, a fixed block 20, a circuit board 30, and a microphone head 40.

The microphone tube 10 may be a housing of a microphone and has a long cylindrical shape, the microphone tube 10 has a cavity 101 therein and openings at both ends, and the inner wall of the microphone tube 10 has a protrusion 11. For example, in the present embodiment, the inner walls of the microphone tube 10 at both sides respectively have the elongated protrusions 11, and the two protrusions 11 are symmetrically distributed on the inner wall of the microphone tube 10. In other embodiments, the number of the protrusions 11 on the inner wall of the microphone tube 10 may be one, two, three or more, and a plurality of the protrusions 11 are distributed on the inner wall of the microphone tube 10 at intervals. The side wall of the mouthpiece 10 also has at least one receptacle 102. In the present embodiment, the number of the insertion holes 102 is two, and the two insertion holes 102 are spaced apart from each other and located on the same straight line on the sidewall of the microphone tube 10. In addition, the outer wall of the microphone tube 10 is also provided with a clamping groove 103, so that the support can be clamped conveniently, and the microphone can be supported.

As shown in fig. 2 and 4, the fixing block 20 is disposed in the cavity 101 of the bobbin 10. The fixing block 20 has a receiving groove 201. The fixing block 20 is disposed in the cavity 101 of the microphone holder 10 and is fixed to the microphone holder 10. Specifically, the fixing block 20 is further correspondingly provided with a groove 202 which is matched with the protrusion 11 of the microphone tube 10, the fixing block 20 is inserted into the cavity 101 of the microphone tube 10 from one end of the microphone tube 10, and the protrusion 11 of the microphone tube 10 is clamped into the groove 202, so that the fixing block 20 cannot rotate relative to the inner wall of the microphone tube 10.

In another embodiment of the present application, the inner wall of the microphone tube 10 has a groove, and the fixing block 20 is correspondingly provided with a protrusion matching with the groove of the microphone tube 10. The fixing block 20 is inserted into the cavity 101 of the microphone tube 10 from one end of the microphone tube 10, and the protrusion of the fixing block 20 is clamped into the groove of the microphone tube 10, in this way, the fixing block 20 cannot rotate relative to the inner wall of the microphone tube 10, and the fixing block 20 and the microphone tube 10 are fixed in a matching manner. It can be understood that, by the way that the protrusion and the groove are mutually matched, the matching and fixing between the microphone tube 10 and the fixing block 20 can be realized without adopting other fasteners such as screws, the use amount of the fasteners such as the screws is reduced, meanwhile, the assembly is convenient, and the assembly difficulty is reduced.

In other embodiments, the microphone tube 10 and the fixing block 20 may be fixed by other methods such as clamping, buckling, and the like.

In another embodiment of the present application, the number of the protrusions 11 or the grooves of the microphone tube 10 is plural and is distributed at intervals on the inner wall of the microphone tube 10; the number of the grooves 202 or the protrusions of the fixing block 20 is correspondingly plural and is distributed at intervals on the periphery of the fixing block 20. The protrusions 11 or grooves of the mouthpiece pipe 10 are fitted with the grooves 202 or protrusions of the fixing block 20 in a one-to-one correspondence, respectively. The circuit board 30 is received in the receiving groove 201 of the fixing block 20. At least one of the microphone tube 10 and the fixing block 20 is fixed to the circuit board 30 in a fitting manner, so that the circuit board 30 is not easily shaken or displaced. The circuit board 30 is a PCBA board and is soldered with an AUX socket 31. The number and location of the AUX sockets 31 correspond exactly to the number and location of the receptacles 102 of the microphone tube 10. The AUX jack 31 is fitted into the jack 102.

In this embodiment, the number of the accommodating groove 201 is one, the number of the grooves 202 is two, and the two grooves 202 are distributed on two sides of the accommodating groove 201. Because the depth of the accommodating groove 201 is relatively deep, the whole fixing block 20 is concave. The fixed block 20 is substantially cylindrical, the outer wall of the fixed block 20 is circumferentially partitioned by the receiving groove 201 and the groove 202 to form a plurality of supporting surfaces 22 attached to and abutting against the inner wall of the microphone bobbin 10, and the supporting surfaces 22 are arc-shaped. After the fixed block 20 is arranged in the cavity 101 of the microphone tube 10, all the supporting surfaces 22 are attached to the inner wall of the microphone tube 10, so that internal supporting force is provided for the microphone tube 10, the circuit board can be protected in all directions, the circuit board 30 inside the microphone tube 10 is not easily damaged when the microphone tube 10 is stressed to be sunken, and the phenomenon that the circuit board 30 and the fixed block 20 integrally shake up and down and left and right of the inner wall of the microphone tube 20 can be effectively reduced. Of course, if the inner wall of the bobbin 10 is non-arc-shaped, the supporting surface 22 of the outer wall of the fixing block 20 may also be non-arc-shaped, for example, the two are square, conical, etc., as long as the supporting surface 22 can support and cooperate with the inner wall of the microphone tube 10. In addition, in order to save materials and manufacturing costs and reduce the weight of the entire microphone, the area between the side wall of the receiving groove 201 and the outer wall of the fixing block 20 is hollow. The number of the AUX sockets 31 is two and the two AUX sockets 31 are spaced apart from each other on the same side of the circuit board 30, and the two AUX sockets 31 are inserted into and extend out of the two insertion holes 102 in a one-to-one correspondence. The AUX jack 31 is just flush or substantially flush with the outer wall of the microphone tube 10, which may make the appearance of the entire microphone more beautiful. In addition, the AUX socket 31 of the circuit board 30 is embedded into the jack 102 of the microphone tube 10, so that the outer wall of the microphone tube 10 can limit the circuit board 30 to a certain extent, and further limit the fixed block 20 containing the circuit board 30 to a certain extent, thereby effectively reducing the axial shake of the circuit board 30 along the microphone tube 10 and enabling the fixation of the circuit board 30 to be more stable.

The microphone 40 is disposed in the cavity 101 at the tip of the microphone tube 10 and is electrically connected to the circuit board 30. As shown in fig. 3, the microphone head 40 is inserted into the cavity 101 of the microphone tube 10 from the tip of the microphone tube 10, and the tip of the microphone tube 10 has a limit such that the microphone head 40 cannot move further toward the tip of the microphone tube 10.

The microphone further includes a woven steel mesh 50, a steel mesh 60, a top cover 70, and a bottom cover 80. The woven steel net 50 is cylindrical and is embedded in the cavity 101 of the microphone tube 10, thereby providing a strong internal supporting force to the microphone tube 10, so that the microphone is not easily damaged in its internal structure when the microphone tube 10 is depressed by an external force. A steel mesh 60 is placed on top inside the mouthpiece tube 10. The top cap 70 and the bottom cap 80 are respectively coupled to both ends of the microphone tube 10. For example, in the present embodiment, the steel mesh 60 is screwed to the top end of the microphone tube 10 together with the top cover 70, so that the steel mesh 60 covers the microphone head 40. The bottom cover 80 is screwed to the bottom end of the microphone tube 10, so that the bottom cover 80 abuts against the end of the circuit board 30 and/or the fixing block 20, and the end of the fixing block 20 and/or the circuit board 30 abuts against the inner peripheral wall of the microphone tube 10, and thus the circuit board 30 and/or the fixing block 20 does not move in the axial direction of the microphone tube 10. The bottom cover 80 also has a LOGO plate 81 fixed to a surface thereof for printing LOGO. Alternatively, the signboard 81 uses a PC plastic sheet.

In other embodiments, the circuit board 30 may not abut against the bottom cover 80, and this also serves to reduce the shake of the circuit board 30 along the axial direction of the microphone tube 10, since the AUX socket 31 of the circuit board 30 is inserted into the insertion hole 102 of the microphone tube 10.

When the microphone is assembled, the circuit board 30 is placed in the microphone tube 10, so that the AUX socket 31 is clamped with the jack 102 of the microphone tube 10 to realize pre-positioning; then the fixed block 20 is placed in the cavity 101 of the microphone tube 10, and the fixed block 20 is inserted between the circuit board 30 and the inner wall of the microphone tube 10; then fixing the bottom cover 80 at the bottom end of the microphone tube 10 to fix the fixing block 20 and/or the circuit board 30, so that the microphone tube 10, the bottom cover 80, the fixing block 20 and the circuit board 30 are assembled together to form a fixing part; finally, the woven steel mesh 50, the microphone head 40, the steel mesh 60 and the top cover 70 are sequentially fixed from the top end of the microphone tube 10.

As shown in fig. 5 to 7, the microphone according to the second embodiment of the present invention includes a microphone tube 10, a fixing block 20, a circuit board 30, a microphone head 40, a woven steel mesh 50, a steel mesh 60, a top cover 70, a bottom cover 80, and a fixing screw 90. The second embodiment differs from the first embodiment described above in the bobbin 10, the fixing block 20, the circuit board 30, and the fixing screw 90. Similarly, the microphone tube 10 is shaped like a long tube, the microphone tube 10 has a cavity 101 therein and has openings at both ends, the inner walls of both sides of the microphone tube 10 are respectively provided with elongated protrusions 11 symmetrically distributed, and the ends of the protrusions 11 are provided with connection holes 1101. The number of the set screws 90 corresponds to the number of the protrusions 11. For example, in the present embodiment, the number of the set screws 90 is two.

The fixing block 20 has a receiving groove 201 and a groove 202, the receiving groove 201 is deep, and the whole fixing block 20 is concave. The number of the grooves 202 is two and the grooves are respectively located at two sides of the accommodating groove 201. A plurality of support surfaces 22 are formed between the receiving groove 201 and the groove 202 in the circumferential direction of the outer wall of the fixing block 20 to be fitted and abutted against the inner wall of the microphone tube 10, and the support surfaces 22 are arc-shaped to provide an internal supporting force to the microphone tube 10. Of course, if the inner wall of the bobbin 10 is non-arc-shaped, the supporting surface 22 of the outer wall of the fixing block 20 may also be non-arc-shaped, for example, the two are square, conical, etc., as long as the supporting surface 22 can support and cooperate with the inner wall of the microphone tube 10. Considering that the hollow fixing block 20 is not easy to form good protection for the circuit board 30, the area between the side wall of the accommodating groove 201 and the outer wall of the fixing block 20 is solid, that is, the rest areas except the accommodating groove 201 and the groove 202 are solid, so that the whole strength of the fixing block 20 is higher, the solid fixing block 20 can bear force better, and provide greater supporting force for the microphone tube 10, so that the microphone tube 10 is recessed inwards when being extruded by external force, the internal structure is not easy to damage, and the risk of damage to the circuit board 30 due to deformation of hollow related components is reduced. In addition, in other embodiments, the area between the side wall of the receiving groove 201 and the outer wall of the fixing block 20 may also adopt a porous structure.

The fixing screws 90 are correspondingly clamped in the grooves 202 of the fixing block 20 and matched with the connecting holes 1101 of the protrusions 11, namely, the fixing screws 90 are screwed into the connecting holes 1101, and the edge of the fixing screws 90 is in low contact with the edge of the fixing block 20, so that the fixing block 20 can be further stably fixed with the microphone tube 10, the fixing block 20 can be prevented from rotating relative to the inner wall of the microphone tube 10, and the fixing block 20 can be prevented from axially moving. It will be appreciated that the engagement between the anchor screw 90, microphone tube 10 and anchor block 20 is equally suitable for the first embodiment described above where a hollow anchor block 20 is used.

In another embodiment of the present application, the inner wall of the microphone tube 10 has a groove, the outer wall of the fixing block 20 has a protrusion matching with the groove of the microphone tube 10, the end of the protrusion of the fixing block 20 is provided with a connecting hole, and the number of the fixing screws 90 is the same as the number of the protrusions of the fixing block 20. The fixing screws 90 are respectively clamped in the grooves on the inner wall of the microphone tube 10 in a one-to-one correspondence and matched with the protrusions of the fixing block 20, that is, the fixing screws 90 are screwed into the protruding connecting holes of the fixing block 20, and the edges of the fixing screws 90 are connected with the edges of the grooves of the microphone tube 10 in a low-level manner.

Further, the end of the fixing block 20 facing the bottom end of the microphone tube 10 may further vertically extend out of the first flange 21, the end of the circuit board 30 facing the bottom end of the microphone tube 10 may further vertically extend out of the second flange 32, and the second flange 32 is exposed out of the receiving groove 201 and fixed with the first flange 21 by screws. Thus, the circuit board 30 and the fixing block 20 can be more firmly connected, and the side wall of the circuit board 30 can not abut against the inner peripheral wall of the microphone tube 10; moreover, since the fixing block 20 and the circuit board 30 can be integrally fixed by the screws connecting the first flange 21 and the second flange 32 when the bottom cover 80 is not screwed to the bottom end of the microphone tube 10, axial movement of the fixing block 20 and the circuit board 30 integrally relative to the microphone tube 10 can be further reduced, and therefore, it is possible to limit abutment of the fixing block 20 without relying only on the bottom cover 80. It should be noted that the first flange and the second flange and the engagement therebetween are also applicable to the fixation between the end of the hollow fixing block 20 and the circuit board 30 in the first embodiment.

It can be understood that, when the microphone tube 10 and the fixing block 20 are tightly fitted, so that the microphone tube 10 and the fixing block 20 are not easy to relatively rotate and relatively move axially, the circuit board 30 can be fixed with any one of the microphone tube 10 and the fixing block 20, so as to ensure that the microphone tube 10, the fixing block 20 and the circuit board 30 are stably fitted, and any two of the three are not easy to relatively rotate and relatively move axially. When the microphone tube 10 and the fixed block 20 are not perfectly matched, and a slight relative rotation or axial displacement still exists between the microphone tube 10 and the fixed block 20, the circuit board 30 and the microphone tube 10 can be designed to be matched and fixed, or the circuit board 30 and the microphone tube 10 and the fixed block 20 are both matched and fixed, so that the microphone tube 10, the fixed block 20 and the circuit board 30 are stably matched, and any two of the three are not easy to relatively rotate or axially displace. In summary, at least one of the microphone tube 10 and the fixing block 20 is fixed to the circuit board 30. The fitting and fixing manner of the circuit board 30 and the microphone tube 10 includes, but is not limited to, the following: 1) the AUX jack 31 of the circuit board 30 is inserted into the jack 102 of the microphone tube 10; 2) the side wall of the circuit board 30 abuts against the inner peripheral wall of the microphone tube 10; 3) the end of the circuit board 30 abuts against the inner peripheral wall of the microphone tube 10. The fixing method of the circuit board 30 and the fixing block 20 includes, but is not limited to, the following: 1) the side wall of the circuit board 30 is abutted against the inner wall of the accommodating groove 201 of the fixed block 20; 2) the first flange 21 of the fixing block 20 and the second flange 32 of the circuit board 30 are fixed.

Compared with the prior art, the microphone provided by the application has the advantages that the fixed block 20 is arranged inside the microphone tube 10, and the circuit board 30 is accommodated in the accommodating groove 201 of the fixed block 20, so that the fixed block 20 can well protect the circuit board 30, the circuit board 30 is not easily directly damaged even if the microphone tube 10 of the microphone is stressed and is inwards sunken, and the risk that the circuit board 30 is damaged due to the stress of the outer wall of the microphone tube 10 is reduced; in addition, the fixed block 20 is matched and fixed with the bobbin tube 10, so that the fixed block 20 can be prevented from rotating relative to the bobbin tube 10 on one hand, and on the other hand, assembly can be completed without any other fasteners, the number of fasteners such as screws and bolts in the traditional structure is reduced, assembly among all the parts is simplified and stable, the assembly efficiency can be improved, the cost is lower, and the device is convenient to assemble and disassemble and convenient to maintain.
