Description

Technical Field

[0001] This application relates to the technical field of headphones, and particularly to a wireless over-ear headphone. Background Art

[0002] Compared with in-ear headphones, wireless over-ear headphones can provide better sound quality and cause less harm to hearing. Therefore, they occupy a large market share among groups with high quality requirements.

[0003] To meet the need for communication, wireless over-ear headphones usually come with a talk microphone. To avoid the constant external influence of the talk microphone on people, Chinese Invention Patent CN108419165A discloses a wireless over-ear headphone. An accommodation hole is fixedly installed inside the headphone main body, and the talk microphone is slidably arranged through the accommodation hole. When a call is needed, the talk microphone can be slowly pulled out from the sliding groove provided in the accommodation hole. When not in use, the talk microphone can be put back into the accommodation hole. However, limited by the width of the headphone main body, the length of the talk microphone is short, and there is a certain distance between the pulled-out talk microphone and the mouth, resulting in unsatisfactory sound collection effect of the microphone. Utility Model Content

[0004] In view of this, the present utility model provides a wireless over-ear headphone to solve the problem in the prior art that, limited by the width of the headphone main body, the length of the talk microphone is short, there is a certain distance between the pulled-out talk microphone and the mouth, and the sound collection effect of the microphone is unsatisfactory.

[0005] The wireless over-ear headphone provided by the present utility model includes two headphone main bodies arranged opposite to each other on the left and right. The two headphone main bodies are connected by a telescopic headband. The headphone main body includes a housing and an ear cup arranged on the inner side surface of the housing. The talk microphone is arranged at the lower part of the front side surface of the housing through a two-stage stretching mechanism. The two-stage stretching mechanism includes:

[0006] Two slide rails, which are arranged parallel to each other up and down along the width direction of the housing, and both ends of the slide rails are fixed to the inner side wall of the housing;

[0007] A bracket, which is slidably arranged on the slide rails. An opening adapted to the bracket is provided on the side wall of the housing. The bracket has a sliding cavity with an open front end, and the talk microphone is slidably inserted and arranged in the sliding cavity.

[0008] For the above wireless over-ear headphone, the talk microphone is arranged at the lower part of the front side surface of the housing of the headphone main body through a two-stage stretching mechanism. When in use, the talk microphone can be pulled out to a longer length, closer to the user's mouth, improving the sound collection effect.

[0009] In the above technical solution, preferably, the intercom microphone is composed of a head and a tail connected together to form an integral structure. The tail is adapted to the sliding cavity and has a thickness smaller than that of the head. Thus, the thickness of the tail of the intercom microphone can be reduced, and further the thickness of the headphone body can be reduced.

[0010] In the above technical solution, preferably, a convex block is provided at the tail end of the tail, and a stop block matching the convex block is provided on the inner wall of the open end of the sliding cavity. Thus, the bracket can be extended by driving the intercom microphone, with a simple structure and convenient use.

[0011] In the above technical solution, preferably, a sliding seat is provided on the top surface of the tail of the bracket, and through holes adapted to the two sliding rails are provided on the sliding seat, and the two sliding rails respectively penetrate through the through holes. This solution arranges the sliding rails in the height direction, reducing the thickness.

[0012] In the above technical solution, preferably, the tail is in the shape of a rectangular plate, with a height greater than the thickness. The rectangular fit avoids torsion when the intercom microphone is pulled out and avoids damaging the cable.

[0013] In the above technical solution, preferably, the sliding rails are inclined downward and inward from the rear to the front, so that after the intercom microphone is pulled out, it is closer to the user's mouth, improving the sound collection effect.

[0014] As can be seen from the above technical solution, the head-mounted wireless headphone provided by the present invention solves the problems that the length of the intercom microphone pulled out in the prior art is short and the sound collection effect is not ideal. Compared with the prior art, the present invention has the following beneficial effects:

[0015] The intercom microphone is arranged at the lower part of the front side of the outer shell of the headphone body through a two-stage stretching mechanism. The two-stage stretching mechanism includes two sliding rails fixed in the outer shell of the headphone body. A bracket with a sliding cavity having an open front end is slidably provided on the sliding rails, and the intercom microphone is slidably inserted into the sliding cavity. When in use, the intercom microphone and the bracket can be pulled out to form two-stage extension, which can pull out a longer length, be closer to the user's mouth, and improve the sound collection effect.

Obviously, the following described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0026] In order to make a clearer explanation and description of the technical solutions and implementation manners of the present utility model, the following introduces several preferred specific embodiments for implementing the technical solutions of the present utility model.

[0027] It should be noted that the orientation words such as "inside, outside", "front, back", and "left, right" in this article are expressed based on the product use state as the reference object. Obviously, the use of the corresponding orientation words does not limit the protection scope of this solution.

[0028] As Figure 1 shown, a head-mounted wireless headphone provided by the present utility model includes two headphone main bodies 10 arranged opposite to each other on the left and right. The two headphone main bodies 10 are connected by a telescopic headband 20 to meet the needs of different users. A telescopic intercom microphone 30 is provided at the lower part of the front side of one of the headphone main bodies 10 for communication. The headphone main body 10 includes an outer shell 11, and an ear cup 12 is provided on the inner side surface of the outer shell 11. The ear cup 12 is made of a soft material to provide a comfortable wearing experience.

[0029] The following description will be made by taking the intercom microphone 30 as being provided on the headphone main body 10 corresponding to the right ear.

[0030] As shown in Figure 2 , Figure 3 As shown in FIGS. Figure 2 and Figure 3 , a two-stage stretching mechanism 13 is provided inside the housing 11 of the earphone main body 10. The two-stage stretching mechanism 13 includes a bracket 131 and two slide rails 132. The two slide rails 132 are respectively arranged in parallel up and down along the width direction of the housing 11. The two ends of the slide rails 132 are respectively fixed to the inner side walls of the housing 11. The bracket 131 is slidably arranged on the slide rails 132.

[0031] Specifically, a slide seat 133 is provided on the top surface of the tail of the bracket 131. Through holes adapted to the two slide rails 132 are provided on the slide seat 133, and the two slide rails 132 respectively penetrate through the through holes.

[0032] The bracket 131 has a slide cavity 134 with an open front end. The intercom microphone 30 is slidably inserted into the slide cavity 134. An opening adapted to the bracket 131 is provided on the side wall of the housing 11.

[0033] The intercom microphone 30 is composed of a head 31 and a tail 32 connected together as an integral structure. The tail 32 is adapted to the slide cavity 134 and has a thickness smaller than that of the head 31. This design can prevent the head 31 from being pushed into the slide cavity 134, making it more convenient to pull out the intercom microphone 30. In this embodiment, the tail 32 is in the shape of a rectangular plate with a height greater than the thickness, reducing the size in the thickness direction and correspondingly reducing the thickness of the earphone main body 10.

[0034] A convex block 33 is provided at the tail end of the tail 32, and a stop block matching the convex block 33 is provided on the inner wall of the open end of the slide cavity 134. By pulling the stop block with the convex block 33, the bracket 131 can be pulled out.

[0035] In the solution of the present utility model, the two-stage stretching of the intercom microphone 30 is realized through the two-stage stretching mechanism 13. Without changing the width of the earphone main body 10, a longer length can be stretched out, making the head of the intercom microphone 30 closer to the mouth, thereby improving the sound collection effect.

[0036] In addition, in the present utility model, the slide rails 132 are inclined downward and inward from back to front. Thus, after the intercom microphone 30 is pulled out, it is closer to the mouth, resulting in a better sound collection effect.

[0037] Based on the description of the above specific embodiments, compared with the prior art, the over-ear wireless earphone provided by the present utility model has the following advantages:

[0038] First, a two-stage stretching mechanism is provided inside the housing of the earphone main body, and the intercom microphone can be stretched out to a longer length, making the head of the intercom microphone closer to the mouth and improving the sound collection effect.

[0039] Second, the thickness of the tail of the intercom microphone is smaller than that of the head, which is convenient for stretching and can prevent the head from being pushed into the slide cavity, making it convenient to use.

[0040] Thirdly, the bracket can be pulled out by the cooperation of the convex block at the tail of the microphone and the stop block on the inner wall of the sliding cavity of the bracket. The structure is simple and convenient to use.

[0041] Finally, it should also be noted that the term "comprising", "including" or any other variant thereof used in this text is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising said element.

[0042] The present utility model is not limited to the above-mentioned optimal implementation manner. Anyone should know that structural changes made under the inspiration of the present utility model, as long as they have the same or similar technical solutions as the present utility model, all fall within the protection scope of the present utility model.
