Description

Technical Field

[0001] The utility model relates to the technical field of audio equipment, in particular to a headset. Background Art

[0002] In the related art, noise-canceling headphones generally install a noise-canceling microphone in the front cavity of the speaker, and the noise-canceling microphone needs to be wired to the rear cavity of the speaker and then connected to the main control board. In this way, the wire has to bypass the retaining wall between the front cavity and the rear cavity of the speaker, and the front cavity and the rear cavity of the speaker need to be sealed and separated. Since the wire passes through, it often leads to poor sealing. In order to solve the sealing problem, a lot of glue needs to be applied around the wire, but too much glue flowing into the cavity affects the acoustic performance, and too little glue affects the sealing performance. At the same time, in actual production, due to the limited space of the ear shell, the glue application operation is also extremely difficult. Utility Model Content

[0031] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] In the description of the present utility model, it is necessary to understand that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] like Figure 1 As shown, the present application involves an earphone, which can be an in-ear earphone, a neck-mounted earphone, a bone conduction earphone or a head-mounted earphone; further, the earphone can be a wired earphone or a TWS earphone; the earphone can be configured with a call noise reduction function and / or an intelligent noise reduction function, and at the same time, can also be configured with stereo surround and other functions.

[0035] like Figure 3 As shown, the earphone includes an ear shell 100, a speaker 200, a first component 300 and a second component 400.

[0036] like Figure 1 , Figure 3 As shown, the ear shell 100 is the outer shell of the earphone, and only a part of the ear shell 100 is shown in the figure. The ear shell 100 is used to protect the devices arranged inside it.

[0037] like Figure 3 As shown, the speaker 200 is disposed in the concha 100 , and the internal space of the concha 100 forms a first chamber 110 located on one side of the speaker 200 and a second chamber 120 located on the other side of the speaker 200 .

[0038] Specifically, the speaker 200 is disposed in the concha 100 , and separates the inner space of the concha 100 into a first chamber 110 and a second chamber 120 .

[0039] Combination Figure 3 and Figure 4 Furthermore, a connecting piece 210 is provided on the speaker 200 . The connecting piece 210 penetrates the speaker 200 . One end of the connecting piece 210 faces the first chamber 110 , and the other end faces the second chamber 120 .

[0040] Specifically, the connector 210 is integrated on the speaker 200, and the connector 210 passes through the speaker 200, and the two ends of the connector 210 are respectively facing the first chamber 110 and the second chamber 120. In this way, the connector 210 can serve as a bridge to connect the components in the first chamber 110 and the components in the second chamber 120.

[0041] Combination Figure 3 , Figure 6 and Figure 7 More specifically, the speaker 200 is provided with an assembly hole 201, and the two ends of the assembly hole 201 are respectively connected to the first chamber 110 and the second chamber 120, and the connecting piece 210 is passed through the assembly hole 201 to achieve the fixation of the connecting piece 210 and the speaker 200, and ensure that the two ends of the connecting piece 210 are respectively facing the first chamber 110 and the second chamber 120.

[0042] It should be noted that the connecting member 210 is interference fit with the hole wall of the assembly hole 201; or, a sealant is provided between the connecting member 210 and the hole wall of the assembly hole 201; or, a sealing ring is provided between the connecting member 210 and the hole wall of the assembly hole 201. In this way, on the one hand, the fixing of the connecting member 210 and the speaker 200 can be achieved, and on the other hand, the sealing between the connecting member 210 and the assembly hole 201 can be ensured.

[0043] The connecting member 210 is made of a conductive material, and the conductive material may be, but is not limited to, gold, silver and copper.

[0044] like Figure 5 As shown, the speaker 200 has a speaker bracket, the interior of the speaker bracket is used for mounting other components of the speaker 200 , and the side of the speaker bracket has a connecting portion 220 , and the assembly hole 201 is opened on the connecting portion 220 .

[0045] It is understandable that the assembly hole 201 is separated from the inner space of the speaker bracket, so that the assembly hole 201 can be prevented from affecting the acoustic effect of the speaker 200 .

[0046] Combination Figure 2 , Figure 3 and Figure 4The first component 300 is disposed in the first chamber 110 , and the first component 300 is electrically connected to one end of the connector 210 ; the second component 400 is disposed in the second chamber 120 , and the second component 400 is electrically connected to the other end of the connector 210 .

[0047] It is understandable that the first component 300 is disposed in the first chamber 110, and the second component 400 is disposed in the second chamber 120. The electrical connection between the first component 300 and the second component 400 can be achieved by using the connector 210 that penetrates the speaker 200. The connector 210 penetrates the speaker 200, and compared with the traditional solution in which the wire bypasses the retaining wall to achieve the connection between the first component 300 and the second component 400, it is easier to achieve sealing.

[0048] Specifically, before the speaker 200 is assembled to the ear shell 100, the connector 210 can be assembled to the speaker 200, and the assembly process will not be limited by the narrow operating space inside the ear shell 100; in addition, the connector 210 is fixed to the speaker 200 by passing through the speaker 200. Whether sealing is achieved by glue, a sealing ring, or an interference fit between the connector 210 and the speaker 200, it is relatively easy to achieve the purpose of effective sealing.

[0049] like Figure 3 As shown, it should be noted that, in some embodiments, the first chamber 110 is located in front of the speaker 200, and the second chamber 120 is located behind the speaker 200. The first chamber 110 is also called the front chamber of the speaker, and the second chamber 120 is also called the rear chamber of the speaker. The first component 300 is a noise reduction microphone; the second component 400 is a main control board.

[0050] It is understandable that the noise reduction microphone is usually set in the front cavity of the speaker to achieve noise reduction; and the main control board is usually set in the rear cavity of the speaker, utilizing the space in the rear cavity of the speaker, while also reducing the impact on acoustic performance.

[0051] It should be noted that the first component 300 and the second component 400 may also be other components. Similarly, the number of the connectors 210 provided on the speaker 200 is not limited to one, and a plurality of connectors 210 may be provided on the speaker 200 to meet the electrical connection of the plurality of components respectively located in the first cavity 110 and the second cavity 120.

[0052] Combination Figure 4 and Figure 5 In some embodiments, the first component 300 is connected to a conductive column 310 , and the conductive column 310 abuts against one end of the connector 210 .

[0053] It is understandable that the conductive column 310 abuts against one end of the connector 210 to achieve electrical connection between the conductive column 310 and the connector 210. At the same time, the conductive column 310 abuts against the connector 210 to achieve electrical connection between the two without the aid of other fixings, which can reduce the assembly process.

[0054] The first component 300 is connected to the conductive member 320 , and the conductive column 310 is connected to the conductive member 320 , thereby achieving electrical connection between the first component 300 and the conductive column 310 .

[0055] Combination Figure 6 and Figure 7 Furthermore, the connector 210 is inserted into the assembly hole 201 and is limited by the hole wall of the assembly hole 201. The hole wall of the assembly hole 201 is used to limit the connector 210 from moving toward the second chamber 120 under the pressure of the conductive column 310.

[0056] It is understandable that when the conductive column 310 abuts against the connector 210, a force will be applied to the connector 210 toward the second chamber 120. By limiting the connector 210 by using the hole wall of the assembly hole 201, the connector 210 can be prevented from moving toward the second chamber 120 due to the pressure of the conductive column 310.

[0057] Specifically, a limiting step 202 is formed at one end of the assembly hole 201 close to the first chamber 110, and the connecting member 210 includes a main body 211 and a limiting portion 212 connected to one end of the main body 211. The main body 211 is inserted into the assembly hole 201 and the limiting portion 212 is limitedly matched with the limiting step 202.

[0058] It can be understood that the limiting portion 212 is connected to the side wall of the main body 211 and protrudes from the side wall of the main body 211. The limiting portion 212 and the main body 211 are an integrally formed structure. The limiting portion 212 is used to abut against the limiting step 202. The limiting step 202 is used to prevent the connector 210 from moving toward the second chamber 120 due to the pressure of the conductive column 310.

[0059] Of course, in other embodiments, the main body 211 and the limiting portion 212 may also be fixed by welding.

[0060] Furthermore, the limiting portion 212 is connected to the side wall of the main body 211 and protrudes from the side wall of the main body 211. It can be understood that under the action of the limiting portion 212, the surface area of ​​the end of the connector 210 close to the first chamber 110 is increased. In this way, the conductive column 310 can have a larger range to adapt to the position error of the connector 210, ensuring that the conductive column 310 can have good contact with the connector 210.

[0061] It should be noted that, in some other embodiments, the conductive column 310 and the connector 210 may be pre-welded together, and then the speaker 200 and the first component 300 are respectively installed in the ear shell 100 .

[0062] Combination Figure 7 and Figure 8 In some embodiments, a first limiting plane 213 is provided on the side wall of the connecting member 210, and a second limiting plane is provided on the hole wall of the assembly hole 201. The first limiting plane 213 and the second limiting plane are arranged in close contact with each other, and the first limiting plane 213 and the second limiting plane cooperate to form a limiting structure for limiting the rotation of the connecting member 210 around the axis of the assembly hole 201.

[0063] It can be understood that after the connector 210 is assembled into the assembly hole 201, the connector 210 is restricted from rotating relative to the assembly hole 201, which can reduce the risk of failure of the connection between the earphone and the first component 300 and / or the second component 400 due to vibration causing the connector 210 to rotate; at the same time, it can also prevent the connector 210 from being worn due to rotation relative to the assembly hole 201, reducing the risk of the sealing effect between the connector 210 and the wall of the assembly hole 201.

[0064] like Figure 4 As shown, in some embodiments, one end of the connector 210 away from the first cavity 110 extends out of the assembly hole 201 , and the second component 400 has a connecting terminal 410 , which is electrically connected to the end of the connector 210 away from the first cavity 110 .

[0065] The connection terminal 410 and the connection member 210 can be fixed by welding. One end of the connection member 210 away from the first chamber 110 extends out of the assembly hole 201, which can facilitate the connection operation between the connection member 210 and the connection terminal 410.

[0066] In the earphone of the present application, the first component 300 is arranged in the first chamber 110, and the second component 400 is arranged in the second chamber 120. By using the connector 210 that is inserted through the speaker 200, the electrical connection between the first component 300 and the second component 400 can be achieved. Among them, the connector 210 is inserted through the speaker 200. Compared with the traditional solution, the wire bypasses the retaining wall to achieve the connection between the first component 300 and the second component 400, which makes it easier to achieve sealing. Specifically, before the speaker 200 is assembled to the ear shell 100, the connector 210 can be assembled to the speaker 200 first, and the assembly process will not be limited by the narrow operating space inside the ear shell 100; in addition, the connector 210 is fixed to the speaker 200 by inserting the speaker 200. Whether it is achieved by glue, a sealing ring, or an interference fit between the connector 210 and the speaker 200, it is easier to achieve the purpose of effective sealing.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0068] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
