Description

Technical Field

[0001] The present invention relates to the field of microphone production and manufacturing, and in particular to a microphone, an earphone and a microphone assembling method. Background Art

[0002] With the development of communications and the increasing demand for audio-visual entertainment, headphones are used more and more frequently in our lives, which in turn has led to the rapid development of the headphone manufacturing industry. The microphones of headphones are divided into unidirectional microphones and omnidirectional microphones. Unidirectional microphones are also called pressure-type microphones. They generate electrical signals by changing the pressure difference on both sides of the microphone's diaphragm. Omnidirectional microphones are also called pressure-type microphones. They generate electrical signals by changing the pressure on one side of the microphone's diaphragm. In related technologies, the overall structure of the microphone is designed and manufactured separately according to the type of microphone. The structural parts of unidirectional microphones and omnidirectional microphones are not interchangeable. If the type of microphone needs to be changed when upgrading a product, it is often necessary to redesign the structure of the microphone, which increases the cost of redesign and manufacturing.

In this specification, the exemplary expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0044] The first embodiment of the present application proposes a microphone that is suitable for the production of microphones in two working states through the same bracket 100, avoiding the process of designing microphone structural parts multiple times and improving the compatibility of microphone components in production.

[0045] like Figure 1 and Figure 2 As shown, the microphone of the present application includes a bracket 100 and a sound receiving assembly 270. The bracket 100 includes a main body 110 and an abutting portion 120. The main body 110 is provided with a mounting hole 130 that extends through the main body 110. The abutting portion 120 is connected to the main body 110 and located within the mounting hole 130, thereby dividing the mounting hole 130 into a first receiving compartment 160 and a second receiving compartment 170. The first receiving compartment 160 and the second receiving compartment 170 are arranged sequentially along the extension direction of the mounting hole 130. The abutting portion 120 is provided with a first through-hole 140 that connects the first receiving compartment 160 and the second receiving compartment 170. The abutting portion 120 is arranged in a continuous annular shape; in other embodiments, the abutting portion 120 may also be arranged in a discontinuous annular shape. The sound receiving assembly 270 is located in the first receiving compartment 160. The abutting portion 120 serves to determine the installation depth of the sound receiving assembly 270. During the assembly of the microphone, the sound receiving component 270 is installed into the first accommodating chamber 160 until it abuts against the abutting portion 120, so that the position of the sound receiving component 270 in the mounting hole 130 can be determined, which can prevent differences in the microphone's sound receiving effects due to different assembly depths of the sound receiving component 270. On the other hand, the provision of the abutting portion 120 achieves the assembly depth positioning of the sound receiving component 270 in the mounting hole 130 through a mechanical structure, without the need for connection methods such as gluing or welding, thereby preventing the failure of glue bonding or weak welding to cause the positioning of the sound receiving component 270 to fail, thereby causing it to shake in the mounting hole 130. The provision of the abutting portion 120 enhances the stability of the product and increases the service life of the product.

[0046] In some embodiments, as Figure 1 and Figure 2As shown, the sound receiving assembly 270 includes a second filler 220 and a sound receiving element 280. The second filler 220 defines an inner cavity, and the sound receiving element 280 is located within the inner cavity and enclosed by the second filler 220. Through holes are formed at both ends of the second filler 220 along the extension direction of the mounting hole 130. This allows both ends of the sound receiving element 280 to communicate with the external environment when the sound receiving element 280 is assembled into the second filler 220. The second filler 220 is capable of undergoing a certain degree of elastic deformation, thereby enabling the sound receiving element 280 to be inserted into and removed from the through holes. In this embodiment, there are two different types of sound receiving assemblies 270. For ease of description, the two types of sound receiving assemblies 270 are respectively designated as the first sound receiving assembly and the second sound receiving assembly.

[0047] When the sound receiving component 270 is the first sound receiving component and the second receiving chamber 170 is sealed so that the first sound receiving component is connected to the external environment on one side, the microphone can operate in the first state, for example, Figure 2 As shown, the first sound receiving component is a sound receiving component 270 of an omnidirectional microphone. The second receiving chamber 170 is sealed using a sealant 230 such as glue or solid silicone, so that the first sound receiving component is connected to the external environment on one side. The sound signal can only enter the sound receiving component 270 from the upper side of the sound receiving component 270 in the figure. The strength of the output signal of the microphone depends on the pressure on the diaphragm in the sound receiving component 270, thereby realizing the recording of sounds at different angles.

[0048] When the sound receiving component 270 is a second sound receiving component and the second receiving chamber 170 is in communication with the external environment so that both sides of the second sound receiving component are in communication with the external environment, the microphone can operate in the second state. Figure 3 As shown, the second sound receiving assembly is a sound receiving assembly 270 with a unidirectional microphone. The second receiving chamber 170 is connected to the external environment, and thus both sides of the second sound receiving assembly are connected to the external environment. Acoustic signals can enter the sound receiving assembly 270 from the upper and lower sides of the sound receiving assembly 270 in the figure, forming a pressure difference on both sides of the diaphragm. The magnitude of this pressure difference enables the recording of sound in the direction of the mounting hole 130. To improve the sound recording effect, in some embodiments, the second receiving chamber 170 is provided with a first filling member 210, such as a silicone sleeve, to reduce the formation of echoes after the sound enters the chamber. A tuning mesh 240 can be provided on the first filling member 210 to filter and adjust the sound signal.

[0049] Based on the above, the structure of this microphone can be adjusted differently for different sound receiving assemblies 270, thereby adapting to the assembly of different types of microphones. During product production and assembly, there is no need to design separate structural components for each type of microphone, thereby saving time and manufacturing costs for different structural components. Furthermore, because the structures of this microphone are generally similar, different types of microphones can be assembled on a common production line during production and assembly, requiring only different operators to perform the individual assembly steps. This optimizes the production process, integrates and modularizes the production line, improves overall production efficiency, and reduces production costs.

[0050] In some embodiments, the main body 110 defines a third storage compartment 180, which can accommodate an electronic device 250. Depending on the product requirements, the electronic device 250 can be a circuit board or a light-emitting component for processing electrical signals, such as Figure 2 and Figure 3 As shown in FIG. 1 , in this embodiment, a light-emitting component is provided in the third storage compartment 180. The light-emitting component can emit different light signals according to the working status of the product, thereby providing intuitive instructions to the user. The two sides of the light-emitting component are respectively engaged with the two side surfaces of the main body 110, and then fixed in the third storage compartment 180, and is located in the middle of the third storage compartment 180, as shown in FIG. Figure 2 and Figure 3 As shown, a certain amount of space is left on the left and right sides of the light-emitting component. On the one hand, the hollow structure is made to reduce the overall weight of the bracket 100. On the other hand, the larger cavity is also conducive to the heat dissipation of the light-emitting component and prevents the circuit board or light source from being damaged by excessive temperature.

[0051] In some embodiments, a protrusion 260 is provided on the outer wall of the sound receiving assembly 270, and a positioning groove is provided on the inner wall of the first receiving compartment 160. The protrusion 260 engages with the positioning groove to limit the rotation of the sound receiving assembly 270 within the first receiving compartment 160. The positioning groove is generally provided at the opening of the mounting hole 130 to facilitate the insertion of the protrusion 260.

[0052] In some embodiments, as Figure 4As shown, a first groove 190 is provided on the inner wall of the first storage compartment 160. The first groove 190 extends toward the third storage compartment 180 so that the first groove 190 connects the first storage compartment 160 and the third storage compartment 180. The microphone further includes a wire (not shown in the figure). The wire passes through the first groove 190, and the two ends of the wire are respectively connected to the sound receiving assembly 270 and the electronic device 250. In this embodiment, the wire connects the sound receiving assembly 270 and the light emitting assembly, so that the light emitting assembly can receive the electrical signal transmitted by the sound receiving assembly 270 and generate different types of light sources to indicate the current working status of the sound receiving assembly 270. In other embodiments, depending on the different functions of the electronic device 250 installed in the third storage compartment 180, the wire serves to transmit electrical signals between the electronic device 250 and the sound receiving assembly 270.

[0053] In an improved embodiment based on the above embodiment, a second groove 200 is provided on the abutting portion 120. The second groove 200 extends along the extension direction of the first groove 190, one end of the second groove 200 is connected to the first groove 190, and the other end is connected to the first through hole 140. After assembly, the sound receiving component 270 abuts against the abutting portion 120, and the wires are passed through the first groove 190 and the second groove 200. In this embodiment, the wires are led out from the bottom of the sound receiving component 270. In order to avoid the wires led out from the sound receiving component 270, as shown in FIG. Figure 4 As shown, a second groove 200 is provided on the abutting portion 120, so that the wire can pass through the second groove 200 and the first groove 190 in sequence and then connect to the electronic device 250 in the third storage compartment 180. The provision of the second groove 200 allows the bottom of the sound receiving assembly 270 to abut against the abutting portion 120, avoiding the sound receiving assembly 270 being raised due to the presence of the wire, thereby increasing the occupied space along the extension direction of the mounting hole 130. On the other hand, the provision of the second groove 200 also facilitates the bending of the wire, avoiding the wire from breaking due to excessive bending angles. The provision of the second groove 200 allows the abutting portion 120 to avoid the wire, allowing the wire to have sufficient space to bend without a sudden change in the extension direction.

[0054] In other improved embodiments, reference Figure 1 、 Figure 4 and Figure 5 As shown, a protrusion 260 is provided on the outer wall of the sound receiving assembly 270, and the protrusion 260 is engaged with the first groove 190, thereby limiting the rotation of the sound receiving assembly 270 in the first receiving chamber 160. Figure 5As shown, in this embodiment, the raised portion 260 extends along the mounting hole 130, thereby serving as a guide during the installation of the sound receiving assembly 270. Due to the relatively small overall size of the sound receiving assembly 270, it is prone to flipping due to uneven force during installation, causing the sound receiving assembly 270 to tip sideways within the first accommodating compartment 160. The small space within the first accommodating compartment 160 makes it difficult to correct the sound receiving assembly 270. The provision of the raised portion 260, on the one hand, limits the rotational freedom of the sound receiving assembly 270, and on the other hand, serves as a guide during assembly, effectively preventing the sound receiving assembly 270 from flipping during installation into the first accommodating compartment 160. Furthermore, the provision of the first groove 190 not only serves to thread the wires but also serves to limit the rotation of the sound receiving assembly 270. This eliminates the need for separate grooves for positioning and threading, thereby simplifying the structure.

[0055] Based on the above embodiment, in a further embodiment, a first gap is defined between the protrusion 260 and the bottom of the first groove 190 along the extension direction of the mounting hole 130. The wire is threaded through the first gap, and the displacement of the wire along the extension direction of the mounting hole 130 is limited by the protrusion 260 and the bottom of the first groove 190. That is, the protrusion 260 and the bottom of the first groove 190 jointly constrain the wire, ensuring a neat and compact arrangement of the wires within the microphone. By properly sizing the protrusion 260, when the sound receiving assembly 270 is secured within the first accommodating compartment 160, the protrusion 260 firmly abuts the wires, thereby securing the wires and preventing any movement that could cause unstable signal transmission. In this embodiment, in addition to the positioning and threading functions of the first groove 190, the first groove 190, in conjunction with the protrusion 260, also secures the wires.

[0056] In some embodiments, as Figure 3 As shown, the microphone also includes a first filler 210. When the microphone is in the second state, the first filler 210 is located within the second receiving chamber 170. The first filler 210 has a second through hole 150, which communicates with the first through hole 140, preventing the first filler 210 from obstructing the transmission of acoustic signals. The first filler 210 may be a silicone sleeve, thereby filling the second receiving chamber 170, reducing echo caused by the larger cavity and enhancing sound recording. Furthermore, a tuning mesh 240 may be provided on the first filler 210 to filter and adjust the acoustic signal.

[0057] In some embodiments, for convenience of description, Figure 4 and Figure 6As shown, the four side surfaces of the main body 110 are defined as a first side surface 290, a second side surface 300, a third side surface 310, and a fourth side surface 320. The first side surface 290 and the second side surface 300 are parallel and opposite to each other along the extending direction of the mounting hole 130. The third side surface 310 and the fourth side surface 320 are perpendicular to the first side surface 290. The first side surface 290 and the third side surface 310 are connected by a first transition surface 330, and the first side surface 290 and the fourth side surface 320 are connected by a second transition surface 340. The mounting hole 130 defines a first opening 350 on the first side surface 290 and a second opening 360 on at least one of the first transition surface 330 and the second transition surface 340. The minimum distance between the first opening 350 and the abutting portion 120 is greater than the minimum distance between the second opening 360 and the abutting portion 120. Consequently, the sound pickup assembly 270 can be exposed from the second opening 360 along the direction from the third side surface 310 to the fourth side surface 320. In this embodiment, the first transition surface 330 and the second transition surface 340 can be inclined surfaces or arc surfaces. The diameter of the mounting hole 130 is greater than the width of the first side surface 290 and the fourth side surface 320. Therefore, when the mounting hole 130 passes through the main body 110, an intersection line can be formed on at least one of the first transition surface 330 and the second transition surface 340, that is, the second opening 360. Figure 6 As shown, the second opening 360 is lower than the first opening 350. Therefore, during the assembly of the sound receiver assembly 270, the operator can pinch the two sides of the sound receiver assembly 270 to place the sound receiver assembly 270 into the first receiving compartment 160. Alternatively, after the sound receiver assembly 270 is assembled, the operator can pinch the sound receiver assembly 270 through the second opening 360 to remove it from the first receiving compartment 160. The provision of the second opening 360 facilitates the assembly of the sound receiver assembly 270 and makes it easier to load and remove the sound receiver assembly 270.

[0058] In a second aspect, embodiments of the present application provide a headset comprising: a microphone, a housing, and a power supply as described in any of the aforementioned embodiments, wherein the power supply and microphone are located within the housing, and the power supply is electrically connected to a sound receiving assembly 270. By employing the microphone described in the aforementioned embodiments, the headset achieves an integrated and modularized production and assembly process, reducing structural component design and production costs, and increasing profits from a product line.

[0059] refer to Figure 1 、 Figure 2 and Figure 3 The embodiment of the third aspect of the present application further provides a method for assembling a microphone, comprising the following steps:

[0060] S100 prepares the bracket 100 and the sound receiving assembly 270. The bracket 100 includes a main body 110 and an abutting portion 120. The main body 110 is provided with a mounting hole 130 that passes through the main body 110. The abutting portion 120 is connected to the main body 110 and is located within the mounting hole 130 to separate the mounting hole 130 into a first accommodating compartment 160 and a second accommodating compartment 170. The first accommodating compartment 160 and the second accommodating compartment 170 are sequentially arranged along the extending direction of the mounting hole 130. The abutting portion 120 is provided with a first through hole 140 that connects the first accommodating compartment 160 and the second accommodating compartment 170.

[0061] S200 identifies the category of the sound receiving component 270. When the sound receiving component 270 is identified as the first sound receiving component 270, the first sound receiving component 270 is loaded into the first storage compartment 160, and the second storage compartment 170 is closed so that the first sound receiving component 270 is connected to the external environment on one side; when the sound receiving component 270 is identified as the second sound receiving component 270, the second sound receiving component 270 is loaded into the first storage compartment 160, and the second storage compartment 170 is kept connected to the external environment so that both sides of the second sound receiving component 270 are connected to the external environment.

[0062] In step S200, Figure 2 As shown, when the sound receiving component 270 is the first sound receiving component 270, the operator needs to close the second receiving chamber 170, which can be sealed by gluing or filling with a seal 230 such as solid silicone to achieve better sealing and sound insulation effects, thereby preventing the penetration of sound signals on this side and interfering with the normal operation of the first sound receiving component 270.

[0063] In step S200, Figure 3 As shown, when the sound receiving component 270 is the second sound receiving component 270, the first filling piece 210 can be installed in the second receiving chamber 170, thereby maintaining the connectivity between the second receiving chamber 170 and the external environment and reducing the echo of the sound signal caused by the larger cavity.

[0064] In step S200, regardless of whether the sound receiving component 270 is the first sound receiving component 270 or the second sound receiving component 270, a layer of tuning net 240 can be added to the sound receiving component 270, which can not only play a dust-proof effect, but also adjust the sound signal on the other hand, so that the sound signal entering the sound receiving component 270 is softer.

[0065] Based on the above, this microphone assembly method can combine two production lines that produce two different types of microphones into a single production line. Only step S200 requires different processing for the different types of microphones; the remaining steps remain the same. This improves microphone production and assembly efficiency. Furthermore, by using the microphones described in the above embodiment, the same bracket 100 can be used to assemble two different types of sound receiving assemblies 270, eliminating the need to design separate brackets 100 for each type of sound receiving assemblies 270. This improves the integration and modularity of the entire production line and reduces production costs.

[0066] While the embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to the embodiments described above. Various modifications may be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof may be combined with one another unless there is a conflict.
