Description

Technical Field

[0001] This utility model relates to an earphone, and more particularly to the structure of a Bluetooth earphone. Background Technology

[0002] Currently, open-back Bluetooth headphones on the market generally use either clip-on or ear-hook styles as the wearing method.

[0003] First, the ear clip-on style, which clips onto the ear with a curved arm, can put pressure on the ear if worn for extended periods, leading to discomfort such as pain and redness, especially for people with sensitive ear skin. Furthermore, compared to other wearing styles, the earphones are more prone to loosening and falling out during exercise or significant head movement, requiring frequent adjustments during strenuous activities like running or jumping.

[0004] Secondly, for people with unique ear shapes or contours, the ear hook style may not fit the ear well, potentially causing localized pressure and ear pain or discomfort after prolonged wear. Furthermore, if the ear hook is made of a stiff material, it can also increase discomfort. Utility Model Content

[0005] The purpose of this invention is to provide a structure for a Bluetooth headset to solve the technical problems existing in the prior art.

[0006] According to one aspect of the present invention, a structure for a Bluetooth headset is provided, including a sound cavity, a curved arm, and a rear side. The curved arm and the sound cavity together form an ear clip. The sound cavity can enter the concha cavity. The curved arm can rest against the back of the ear. The curved arm and the rear side together form an ear hook. The rear side can be located on the front of the ear. The ear hook has a hooking force on the ear, and the rear side has a resisting force on the front of the ear.

[0007] In some embodiments, one end of the curved arm is connected to the acoustic cavity. When the acoustic cavity, curved arm, and rear side are worn on the ear, the curved arm extends downward from the front of the ear and bends to the back of the ear, then extends upward from the lower back of the ear to the upper back of the ear and bends to the upper front of the ear. One end of the rear side is connected to the other end of the curved arm, and the rear side can rest against the front of the ear. Thus, with this structure, the curved arm can rest against the back of the ear, and the curved arm and acoustic cavity can together form an "ear clip" to be clipped onto the ear, while the rear side can rest against the front of the ear, and the curved arm and rear side can together form an "ear hook" to be hung on the ear.

[0008] In some embodiments, one end of the acoustic cavity is provided with a first connector that can be inserted into one end of the curved arm, and the other end of the curved arm is provided with a second connector that can be inserted into the rear side portion. Thus, the curved arm portion and the acoustic cavity portion can be connected together by the first connector, and the curved arm portion and the rear side portion can be connected together by the second connector.

[0009] In some embodiments, the rear portion is inverted triangular in shape. This allows the rear portion of this shape to fit into the ear.

[0010] In some embodiments, a cavity and a charging pin hole are formed on the rear side, and the charging pin hole is connected to the cavity. Therefore, since a cavity is formed on the rear side, components such as a power supply and a circuit board can be housed within the cavity, and the end of the charging pin can be positioned at the charging pin hole, allowing the power supply of this invention to be charged via the charging pin.

[0011] In some embodiments, a memory wire is also included, which is disposed in the curved arm portion and has a shape consistent with the shape of the curved arm portion. Therefore, by incorporating the memory wire, the curved arm portion can always maintain a certain shape, preventing deformation of the curved arm portion from affecting its performance.

[0012] In some embodiments, the acoustic cavity is provided with a sound outlet, which is located at the front of the acoustic cavity. Therefore, because the sound outlet is located at the front of the acoustic cavity, the acoustic cavity can be inserted into the ear in a slightly in-ear manner. Compared to open-back Bluetooth headphones, the acoustic cavity 1 has a small contact area with the tragus, and the center of gravity of the slightly in-ear acoustic cavity 1 falls within the concha, achieving a stable wearing effect in this slightly in-ear configuration. It is less likely to fall out even during exercise, making it more comfortable to wear and less likely to cause fatigue during prolonged use.

[0013] In some embodiments, the sound cavity is also provided with a sound vent, located at the upper rear part of the sound cavity. This sound vent helps to maintain a stable internal air pressure within the sound cavity.

[0014] The beneficial effects of this utility model are as follows: To solve the problems existing in the prior art, this utility model adopts a wearing method that combines an ear clip and an ear hook. The rear part can rest against the front of the ear, and the ear hook provides a certain degree of support for the ear, reducing the pressure caused by the ear clip. It can also remain stable and secure without displacement during exercise or significant head movement. The ear clip part makes the acoustic cavity more adaptable to a wider range of people, increasing both wearing comfort and the range of applicable users. Furthermore, the curved arm is embedded with a memory wire, which enhances the elasticity of the curved arm, making it easier and more convenient to wear, and resulting in a more comfortable and snug fit.

[0015] Because the sound outlet is located at the front of the sound cavity, the sound cavity can be inserted into the ear in a slightly in-ear manner. Compared with traditional open-ear Bluetooth headphones, the center of gravity of the sound cavity in the slightly in-ear design falls inside the concha, achieving a stable wearing effect in the slightly in-ear shape. It is not easy to fall off even during exercise, making it more comfortable to wear and less likely to cause fatigue during long-term wear. Attached Figure Description

[0021] 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.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] Figures 1-4 The diagram schematically illustrates the structure of a Bluetooth headset according to one embodiment of the present invention.

[0024] like Figures 1-4 As shown, a Bluetooth headset structure includes a sound cavity 1, a curved arm 2, and a rear side 3.

[0025] Combination Figures 1-4 As can be seen, in this embodiment, the curved arm 2 and the acoustic cavity 1 together form the ear clip 4. The acoustic cavity 1 can enter the concha cavity, and the curved arm 2 can rest against the back of the ear. When this utility model is worn on the ear, the curved arm 2 has a certain clamping force on the back of the ear, so the curved arm 2 can be clamped on the back of the ear. Therefore, the curved arm 2 and the acoustic cavity 1 are clamped together on the ear as the ear clip 4. The curved arm 2 and the rear side 3 together form the ear hook 5. The rear side 3 can be located on the front of the ear. The ear hook has a hanging force on the ear, and the rear side 3 has a resisting force on the front of the ear. The ear hook 5 can be hung on the ear to form a supporting function. Because a supporting function is formed, the clamping force of the curved arm 2 can be reduced to prevent the clamping force of the curved arm 2 from being too large and resulting in poor wearing comfort.

[0026] The structure of the curved arm section 2 and the rear side section 3 is described in detail below, with reference to... Figures 1-3 As shown, one end of the curved arm 2 is connected to the sound cavity 1, from... Figure 3 As can be seen, when the acoustic cavity 1, the curved arm 2, and the posterior side 3 are worn on the ear, the acoustic cavity 1 is located in the concha cavity. The curved arm 2 extends downward from the front of the concha cavity and bends to the back of the ear, then extends upward from the back of the ear to the top of the back of the ear and bends to the top of the front of the ear. One end of the posterior side 3 is connected to the other end of the curved arm 2, and the posterior side 3 can rest against the front of the ear. Through this structure, the curved arm 2 can rest against the back of the ear, and the curved arm 2 and the acoustic cavity 1 can together form an "ear clip" form, i.e., the ear clip part 4, which is clipped onto the ear. The posterior side 3 can rest against the front of the ear, and the curved arm 2 and the posterior side 3 can together form an "ear hook" form, i.e., the ear hook part 5, which is hung on the ear. Since the ear hook part 5 formed by the curved arm 2 and the posterior side 3 can provide some support to the ear, the clamping force of the curved arm 2 can be reduced.

[0027] In this embodiment, as Figure 4 As shown, one end of the acoustic cavity 1 can be integrally formed with a first insertion part 13, which can be inserted into one end of the curved arm 2. The other end of the curved arm 2 can be integrally formed with a second insertion part 21, which can be inserted into the rear side part 3. The curved arm 2 and the acoustic cavity 1 can be connected together through the first insertion part 13, and the curved arm 2 and the rear side part 3 can be connected together through the second insertion part 21. Of course, the acoustic cavity 1, the curved arm 2, and the rear side part 3 can also be separated.

[0028] like Figure 1 As shown, in this embodiment, the rear side portion 3 is inverted triangular in shape. This shape of the rear side portion 3 can cooperate with the ear, and when the present invention is arranged as shown... Figure 3When worn on the ear as shown, the back part 3 has a large contact area with the ear, which can improve the wearing comfort.

[0029] In this embodiment, a cavity and a charging pin hole 31 are formed on the rear side 3. The charging pin hole 31 is connected to the cavity. Components such as a power supply and a circuit board can be installed in the cavity. The end of the charging pin can be located at the charging pin hole 31, and the power supply of this utility model can be charged through the charging pin.

[0030] To maintain the shape and strength of the curved arm portion 2, this invention also includes a memory steel wire 6, which is integrally installed in the curved arm portion 2, and the shape of the memory steel wire 6 is consistent with the shape of the curved arm portion 2. By setting the memory steel wire 6, the curved arm portion 2 can always maintain a certain shape, preventing deformation of the curved arm portion 2 from affecting its performance.

[0031] like Figure 2 As shown, a sound outlet 11 is integrally formed on the sound cavity 1. The sound outlet 11 is located at the front of the sound cavity 1. Since the sound outlet 11 is located at the front of the sound cavity 1, the sound cavity 1 can be inserted into the ear in a slightly in-ear manner. Compared with open-back Bluetooth headphones, the sound cavity 1 has a small contact area with the tragus. The center of gravity of the slightly in-ear sound cavity 1 is located in the concha cavity, which achieves a stable wearing effect in the slightly in-ear form. It is not easy to fall off even during exercise, making it more comfortable and easy to wear, and it is not easy to cause fatigue when wearing it for a long time.

[0032] In this embodiment, as Figure 4 As shown, a sound vent 12 can also be integrally formed on the sound cavity 1, located at the upper rear part of the sound cavity 1. The sound vent 12 can keep the internal air pressure of the sound cavity 1 stable.

[0033] This invention employs an ear clip portion 4 and an ear hook portion 5 for wearing. The rear portion 3 rests against the front of the ear, and the ear hook portion 1 provides support to the ear, reducing pressure from the ear clip portion 4. It remains stable and secure even during movement or significant head shaking. The ear clip portion 4 expands the fit of the ear hook portion 1 to a wider range of people, increasing both wearing comfort and applicability. Furthermore, the curved arm portion 2 incorporates a memory wire 6, enhancing its elasticity and making it easier and more convenient to wear, resulting in a more comfortable and snug fit.

[0034] Since the sound outlet 11 is located at the front of the sound cavity 1, the sound cavity 1 can be inserted into the ear in a micro-in-ear manner. Compared with traditional open-ear Bluetooth headphones, the center of gravity of the micro-in-ear sound cavity 1 is located in the concha cavity, achieving a stable wearing effect in the micro-in-ear shape. It is not easy to fall off even during exercise, making it more comfortable to wear and less likely to cause fatigue during long-term wear.

[0035] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that falls within the scope of the claims of this utility model shall be protected by this utility model.
