Description

Technical fields:

[0001] This utility model relates to the field of headphone product technology, and specifically to a light-emitting structure for a Bluetooth headphone. Background technology:

[0002] Most Bluetooth headsets nowadays have indicator lights that display the headset's working status through color and flashing. Taking common in-ear or semi-in-ear headphones as an example, these headsets typically have a head and a stem. The head houses the speaker and battery components, while the stem houses the circuit board. The indicator light is usually located on the surface of the stem's housing. The method used is as follows: an LED is directly mounted on the circuit board, and a light-transmitting hole is made on the stem's housing corresponding to the position of the LED, allowing light from the LED to shine through the hole.

[0003] Due to the limited area of ​​the circuit board in headphones, LED lights typically use LED chips to create a point-like lighting effect. Therefore, the light-transmitting holes are usually small round or oval-shaped, resulting in a monotonous lighting effect for the headphone indicator lights. To create a larger area of ​​illumination, larger light panels or strips are needed. However, these light panels or strips cannot usually be directly mounted on the circuit board; they need to be connected via wires and require a corresponding positioning and mounting structure within the headphone stem's cavity. Since the cavity within the headphone stem is small, a mounting plate is already required. Adding a positioning and mounting structure, along with the light panel or strip, further restricts the already limited installation space within the headphone stem. The current common approach is to increase the size of the headphone stem, resulting in an excessively large stem that negatively impacts the overall aesthetics of the headphones.

[0004] The inventors propose the following improved technical solutions to address the above-mentioned problems. Utility Model Content:

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a light-emitting structure for headphones. This light-emitting structure sets the light-emitting component in the cavity of the head of the headphones and can produce a light-emitting effect with a large area and a certain shape.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a light-emitting structure for headphones, comprising a headphone shell composed of a main body, a front cover, and a rear cover. The main body includes an integrally formed front shell and a rear shell. The front shell and the front cover cooperate to form the head of the headphones, and the rear shell and the rear cover cooperate to form the stem of the headphones. The headphone speaker and battery are installed in the cavity of the head of the headphones, and the headphone circuit board is installed in the cavity of the stem of the headphones. A front cavity is formed inside the front shell, and a rear cavity is formed inside the rear shell. The front cavity and the rear cavity are connected by a connecting hole. The rear cover seals the opening of the rear cavity. A light-emitting hole is provided on the rear shell of the main body, and the front cavity penetrates to the outside through the light-emitting hole. A mounting position is formed near the light-emitting hole in the front cavity, and a light-emitting component is installed at the mounting position. The light-emitting component includes a light-emitting body with a light-emitting surface larger than the light-emitting hole. The light emitted by the light-emitting body shines out through the light-emitting hole, causing the rear shell of the headphones to form a light-emitting area corresponding to the shape of the light-emitting hole.

[0007] Furthermore, in the above technical solution, a rear side surface is formed on the rear housing above the opening end of the rear cavity, and the light-emitting hole is opened on the rear side surface.

[0008] Furthermore, in the above technical solution, the light-emitting component includes: a light-emitting body and a positioning seat, wherein the positioning seat is snapped into the mounting position, and the light-emitting body is pressed tightly against the bottom surface of the mounting position by the positioning seat.

[0009] Furthermore, in the above technical solution, the mounting position includes: a groove formed along the front cavity to the rear, and a positioning groove formed on the side wall of the groove; a light-emitting hole is opened on the bottom surface of the groove.

[0010] Furthermore, in the above technical solution, the shape of the positioning seat matches the groove, and the positioning seat is formed with positioning protrusions corresponding to the positioning groove.

[0011] Furthermore, in the above technical solution, the light-emitting component also includes an elastic isolator, and the light-emitting body, the positioning seat, and the elastic isolator are arranged sequentially from back to front.

[0012] Furthermore, in the above technical solution, the elastic isolator is frame-shaped, and a positioning boss is formed on the front side of the positioning seat to position the elastic isolator.

[0013] Furthermore, in the above technical solution, the elastic insulating element is made of foam or sponge material.

[0014] Furthermore, in the above technical solution, the connecting hole is located on the lower side of the mounting position, the upper end of the circuit board extends to the position of the connecting hole, and the battery in the front cavity is electrically connected to the circuit board through the connecting hole via an electrical connector provided on the upper end of the circuit board. The light-emitting element in the light-emitting component is electrically connected to the circuit board through the connecting hole.

[0015] The present invention, by adopting the above technical solution, has the following advantages:

[0016] 1. The light-emitting component in this utility model is not set in the stem cavity of the earphone, but is set in the cavity of the earphone head. Since the earphone head cavity has a large space, the mounting position for installing the light-emitting component can be conveniently set in the front cavity.

[0017] 2. The light-emitting component of this utility model adopts a light-emitting body with a large light-emitting surface, and at the same time, the light-emitting hole can be used to form an indicator light effect with a specific shape.

[0018] This utility model has a simple structure, is easy to install, and can create a specific indicator light effect, which can significantly enhance the product's market competitiveness. Attached image description:

[0025] The present invention will now be described in detail with reference to the accompanying drawings. In the description of the present invention, the terms "front," "rear," "upper," and "lower" are used to indicate... Figure 5 To express orientation or positional relationship based on a reference point, where "front" is... Figure 5 To the left, "back" is Figure 6 The direction to the right. These are for ease of description only and are not intended to indicate or imply that the device or element referred to must have a specific orientation.

[0026] This utility model relates to a light-emitting structure for headphones, see... Figures 1 to 6 As shown, this utility model can be divided into a head and a stem in terms of shape. The entire earphone shell is composed of a main body 1, a front cover 2, and a rear cover 3. That is, after the main body 1, the front cover 2, and the rear cover 3 are processed separately, they are fixed together by means of snap-fit ​​connection, buckle connection, etc.

[0027] The main body 1 includes a front shell 11 and a rear shell 12 integrally molded from plastic material. A front cavity 110 is formed within the front shell 11, with the opening of the front cavity 110 facing forward. The front shell 11 and the front cover 2 cooperate to form the head of the earphone. The earphone speaker (not shown) and battery 5 are installed in the cavity of the earphone head. The front cover 2 is provided with a sound outlet, and for in-ear earphones, an ear cap 20 is also provided.

[0028] The rear housing 12 of the main body 1 has a rear cavity 120 formed inside, and the opening of the rear cavity 120 faces rearward. The rear housing 12 and the rear cover 3 cooperate to form the stem of the earphone. The circuit board 3 of the earphone is installed in the cavity of the earphone stem along the axial direction of the stem.

[0029] The rear cover 3 is sealed at the opening end of the rear cavity 120. A rear side surface 121 is formed on the rear housing 12 above the opening end of the rear cavity 120. A light-emitting hole 100 is provided on the rear side surface 121. The rear cover 3 does not cover the light-emitting hole 100, allowing the front cavity 110 to penetrate to the outside through the light-emitting hole 100.

[0030] The light-emitting hole 100 can be configured into a certain shape. For example, in this embodiment, the light-emitting hole 100 is crescent-shaped, and the light-emitting hole 100 ultimately produces a crescent-shaped indicator light effect.

[0031] This utility model includes a light-emitting component 6, which comprises a light-emitting body 61, a positioning seat 62, and an elastic isolation member 63, arranged sequentially from back to front. The light-emitting body 61 is an LED light-emitting panel with a large light-emitting surface, and the light-emitting surface of the light-emitting body 61 is larger than the light-emitting hole 100. Thus, when the light-emitting body 61 is attached to the front end of the light-emitting hole 100, the light generated by the light-emitting body 61 shines out through the light-emitting hole 100, causing the rear shell 12 of the earphone to form a light-emitting area corresponding to the shape of the light-emitting hole 100.

[0032] In this invention, the light-emitting component 6 is not located within the rear cavity 120, meaning it does not occupy the mounting space of the circuit board 3. Specifically, a mounting position 13 is formed in the front cavity 110 near the light-emitting hole 100. The light-emitting component 6 is mounted at this mounting position 13. The mounting position 13 includes: a groove 131 formed rearward along the front cavity 110, and a positioning groove 132 formed on the side wall of the groove 131; the light-emitting hole 100 is formed on the bottom surface of the groove 131.

[0033] The light-emitting element 61 is fitted to the bottom surface of the groove 131. The positioning seat 62 is shaped to match the groove 131, and a positioning protrusion 621 corresponding to the positioning groove 132 is formed on the positioning seat 62. The positioning seat 62 is engaged and installed in the mounting position 13 through the positioning protrusion 621 and the positioning groove 132. The light-emitting element 61 is pressed tightly against the bottom surface of the mounting position 13 by the positioning seat 62.

[0034] Since the light-emitting component 6 is installed in the front cavity 110 of the front housing 11, combined with Figure 2 As shown, a battery 5 and a circuit board 51 for circuit connection are also installed inside the front cavity 110. The elastic isolator 63 is used to isolate the light-emitting component 6 from the circuit board 51 in front. The elastic isolator 63 is frame-shaped, and a positioning boss 622 for positioning the elastic isolator 63 is formed on the front side of the positioning seat 62. The elastic isolator 63 is made of foam or sponge material. After assembly, the battery 5 and the circuit board 51 can form a lateral pressure on the elastic isolator 63, thereby pressing against the positioning seat 62 and the light-emitting body 61 through the elastic isolator 63, realizing the lateral positioning of the entire light-emitting component 6.

[0035] The front cavity 110 and the rear cavity 120 are connected by a connecting hole 101. The connecting hole 101 is located on the lower side of the mounting position 13. The circuit board 4 located in the rear cavity 120 extends to the position of the connecting hole 101. It is electrically connected to the battery 5 and circuit board 51 in the front cavity 110 through the connecting hole 101 via an electrical connector provided at the upper end of the circuit board 4. At the same time, the light-emitting element 61 in the light-emitting component 6 is also electrically connected through the connecting hole 101.

[0036] During installation, first connect the light-emitting element 61 electrically to the upper end of the circuit board 4; then, pass the light-emitting element 61 through the connecting hole 101 from the rear cavity 120 into the front cavity 110 and place it at the mounting position 13, while the circuit board 4 is still in the rear cavity 120. Finally, assemble the other components.

[0037] This invention can be used not only in headphones but also in other electronic products. Of course, the above description is merely a specific embodiment of this invention and is not intended to limit its scope. All equivalent changes or modifications made to the structure, features, and principles described in the claims of this invention should be included within the scope of this invention.
