To ensure the stability of the ear hook structure, open-back headphones are typically ergonomically designed for practicality. They also do not block or cover the ears, transmitting sound through the air unlike in-ear headphones which directly block the ear canal. This allows for better awareness of ambient sound, making them safer for outdoor activities like running or cycling. However, they tend to have weaker bass response, are more prone to sound leakage, and offer less privacy.

[0003] Therefore, this application provides an open-back headphone with improved sound leakage to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an open-back headphone that improves sound leakage. By placing the speaker cover and the rear speaker cover at a suitable angle, and by adjusting the angle of the speaker inside the speaker cover, the sound outlet is precisely aligned with the ear canal, thereby improving the problem of excessive sound leakage.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An open-back headphone designed to improve sound leakage includes a connecting strap, a control terminal fixed to one end of the connecting strap, two ear straps, and a body respectively mounted to one end of each of the two ear straps. Both bodies are connected to the control terminal via coils and connecting wires. Each body consists of a speaker back cover, a speaker, and a speaker cover.

[0006] Furthermore, the control terminal includes a volume up / down button, a previous / next track switch button, and a pause button, and the control terminal includes a control housing and an internal control circuit board.

[0007] Furthermore, the other end of the connecting strap is symmetrically provided with a symmetrical shell, and the two auricular straps are respectively connected and combined with the symmetrical shell and the control end.

[0008] Furthermore, a sound outlet is provided at the center of the front end of the speaker cover.

[0009] Furthermore, the angular deviation between the horn cover and the horn rear cover is 18 degrees.

[0010] Furthermore, the horn is embedded inside the horn cover and the horn rear cover, and the horn cover and the horn rear cover are fixed together by a first buckle and a second buckle.

[0011] This utility model has the following beneficial effects: This utility model proposes an open-back headphone that improves sound leakage. By placing the speaker cover and the speaker back cover at a suitable angle, and by adjusting the angle of the speaker inside the speaker cover, the sound outlet is precisely aligned with the ear canal, allowing the sound to be accurately transmitted to the ear canal, reducing sound diffusion, improving sound leakage, and enhancing privacy. This can thus improve the problem of excessive sound leakage. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Reference Figures 1-4 The present invention provides an embodiment of an open-back headphone that improves sound leakage, comprising a connecting strap 2, a control terminal 1 fixed to one end of the connecting strap 2, two ear straps 5, and a body 3 respectively installed at one end of the two ear straps 5. Both bodies 3 are connected to the control terminal 1 through coils and connecting wires. The body 3 is composed of a speaker back cover 301, a speaker 302, and a speaker cover 303.

[0016] Specifically, the main body 3, as the main structure of the entire open-back headphone, contains multiple structural components such as the speaker 302, which is consistent with the structure of traditional headphones to ensure the propagation of sound. The coil and connecting wires are used to connect to the control terminal 1 to ensure the communication transmission after the electrical signal conversion. The connecting strap 2 is used to hang it around the neck for auxiliary installation, and the ear strap 5 can better hang the main body 3 on the ears.

[0017] Reference Figures 1-4 The control terminal 1 includes a volume control button, a previous and next track switch button, and a pause button. The control terminal 1 also includes a control housing and an internal control circuit board. Specifically, the multi-functional button structure of the control terminal 1 can meet all the operation functions of the headphones in daily use, ensuring the convenience and practicality of operation. At the same time, the built-in control circuit board has the same function as the circuit board of commonly used Bluetooth headphones in the existing technology.

[0018] Reference Figures 1-4 The other end of the connecting strap 2 is symmetrically provided with a symmetrical shell 8, and the two ear straps 5 are connected and combined with the symmetrical shell 8 and the control end 1 respectively. The symmetrical shell 8 adopts the same structure as the control end 1 and is formed with the shell of the connecting strap 2 and the shell of the control end 1 using an integrated molding technology. The design of symmetrical shell 8 at the other end can achieve the symmetry of both ends of the entire open-back headphone and improve the comfort of wearing the ear.

[0019] Reference Figure 1 The speaker cover 303 has a sound outlet port 4 at the center of the front end; the angular deviation between the speaker cover 303 and the speaker rear cover 301 is 18 degrees. Specifically, the speaker cover 303 and the back cover are an upper and lower structure; the angle deviation between the speaker cover 303 and the back cover is approximately 18 degrees; during assembly, in order to ensure that the sound outlet can be better aligned with the ear canal, the angle deviation between the speaker cover 303 and the back cover can be 18 degrees or 10 degrees, but the angle of the speaker cover 303 and the back cover cannot be adjusted after assembly; at the same time, the internal speaker 302 can be adjusted in angle according to actual needs within the speaker cover 303 during assembly; finally, the speaker cover 303 and the back cover are fixed with snap fasteners; through the above steps, the sound can be accurately transmitted to the ear canal, reducing sound diffusion, improving sound leakage, and enhancing confidentiality; Specifically, in this embodiment, the speaker is generally assembled perpendicular to the parting surface. When the mold cannot be ejected normally in the perpendicular direction, the angle needs to be adjusted to facilitate ejection. When sound quality adjustment is required, the speaker angle can also be adjusted.

[0020] Reference Figures 1-4The speaker 302 is embedded inside the speaker cover 303 and the speaker rear cover 301. The speaker cover 303 and the speaker rear cover 301 are fixed together by the first buckle 6 and the second buckle 7. The buckle connection method enables quick installation and fixed use.

[0021] Working principle: During installation, the speaker 302 is embedded inside the speaker cover 302 and then fixed. The speaker cover 303 and the speaker back cover 301 are then combined. After the entire open-back headphone structure is assembled, the headphone's connecting strap 2 is hung around the user's neck. After the ear strap 5 is hung on the outer contour of the ear, the sound output port 4 of the main body 3 can be directly aligned with the user's ear canal. By precisely aligning the sound output nozzle with the ear canal, i.e., aligning the sound output hole on the headphone with the ear canal hole, the problem of excessive sound leakage can be improved.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
