[0025] In order to make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0026] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" 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 an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0027] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0028] like Figure 1-Figure 6As shown, this embodiment provides an open-type earphone, comprising: a shell 1, a light source 2, a light-guiding film 3, a light-reflecting film 4 and a light-blocking film 5, wherein the light source 2 is installed in the shell 1, and the light source 2 emits light toward the outside of the shell 1, the light-guiding film 3 is installed on the light-emitting side of the light source 2, the light-reflecting film 4 is attached to the side of the light-guiding film 3 facing the light source 2, and the light-guiding film 3 and the light-reflecting film 4 are both provided with through holes 15 corresponding to the light source 2, so that the light emitted by the light source 2 can be transmitted into the light-guiding film 3, and the light-blocking film 5 is correspondingly arranged on the through holes 15 to prevent the light emitted by the light source 2 from directly irradiating the shell 1.

[0029] Based on the above scheme, the light source 2, the light-guiding film 3, the reflective film 4 and the light-blocking film 5 are all installed inside the shell 1, and the luminous side of the shell 1 is defined as the light-emitting surface 1011, that is, the side of the shell 1 opposite to the light source 2; the through hole 15 opened on the light-guiding film 3 corresponds to the light source 2, and the light emitted by the light source 2 will pass through the through hole 15, and in order to avoid the light emitted by the light source 2 directly hitting the light-emitting surface 1011 of the shell 1, resulting in uneven light emission, the unevenness here means that the light directly transmitted without passing through the light-guiding film 3 will be brighter than the light transmitted through the light-guiding film 3, so that the light emission appears uneven from the overall point of view, so a light-blocking film 5 is arranged at the position of the through hole 15, and the function of the light-blocking film 5 is to block the light from the light source 2 from directly hitting the shell 1, to ensure the uniformity of light emission, and at the same time to ensure that the light will diffuse into the light-guiding film 3 through the side wall of the through hole 15, so as to form a uniform surface light source in the light-guiding film 3, and since the light-blocking film 5 is not arranged at other positions of the light-guiding film 3, it will not affect the light source on the light-guiding film 3. The diffusion of the light source 2 of the light-guiding film 3 can be evenly transmitted through the shell 1, while the light on the light-guiding film 3 is diffused downward. The above and below mentioned here are defined with reference to the light-emitting direction of the light source 2. The light-emitting direction of the light source 2 is upward, and vice versa. Therefore, in order to avoid unnecessary diffusion and waste of light, a reflective film 4 is arranged below the light-guiding film 3. The reflective film 4 can reflect the light diffused downward on the light-guiding film 3 to the upper side, thereby improving the brightness of the light-emitting surface 1011 of the shell 1, making the lighting effect of the earphone clearer and more obvious; here, the sizes of the reflective film 4 and the light-guiding film 3 need to be consistent, and the reflective film 4 is located below the light-guiding film 3. In order to avoid the reflective film 4 from blocking the light, a through hole 15 needs to be opened at the corresponding position of the reflective film 4, that is, the through holes 15 opened on the reflective film 4 and the light-guiding film 3 are through, and the position and size are consistent, so that the light emitted by the light source 2 can diffuse to the light-guiding film through the side wall of the through hole 15. In the present solution, the light-guiding film group composed of the reflective film 4, the light-guiding film 3 and the light-blocking film 5 enables the light-emitting surface 1011 of the shell 1 to emit light evenly, and the thickness of the entire light-guiding film group is not large, and the thickness does not change much compared to the thickness of the headphones without adding lighting effects. In this way, it is possible to add a differentiated selling point to the headphones while still maintaining the exquisite appearance of the headphones, thereby improving the user experience of the headphones and thus increasing the market competitiveness of the product.

[0030] like Figure 6 As shown, in order to improve the uniformity of the surface light source formed on the light-guiding film 3, a plurality of concave points 301 are arranged on the light-guiding film 3. By setting the concave points 301, light can be gathered at the concave points 301 to form light spots. The plurality of light spots formed by the plurality of concave points 301 can form a complete and uniform surface light source. Compared with the light-guiding film 3 with a flat surface, the surface light source formed by the light-guiding film 3 with the concave points 301 will be more uniform and bright.

[0031] Furthermore, the concave points 301 provided on the light guide film 3 have at least two arrangements. The first is that the concave points 301 are evenly spaced and distributed on the side of the light guide film 3 facing the light source 2. This arrangement is for the case where the light is normally emitted only through the housing 1. In simple terms, a uniform surface light source is directly formed on the light guide film 3. The second is that the distribution of the concave points 301 on the light guide film 3 can be used to connect all the concave points 301 to form different shapes, that is, animals or words, or other patterns are presented after the complete connection. The production distribution of the concave points 301 can be carried out according to different design requirements. The concave points 301 are designed and produced during the production process of the light guide film 3, so that the light content can be directly presented after assembly, so that the headset can better interact with the user when in use, and the presented content is more diverse and interesting.

[0032] In order to prevent the light emitted by the light source 2 from being wasted, the installation position of the light source 2 is preferably set in the through hole 15. When the light source 2 is set in the through hole 15, since the top of the through hole 15 is blocked by the light-blocking film 5, most of the light emitted by the light source 2 will be diffused into the light-guiding film 3 through the side wall of the through hole 15. In this way, the waste rate of resources is very low, and the light emitted by the light source 2 can be effectively and reasonably used.

[0033] As an optional embodiment, the light source 2 is arranged below the through hole 15, that is, the light source 2 is not arranged in the through hole 15, and a certain gap is left between the light source 2 and the through hole 15. The specific value of the gap can be adjusted according to the power of the light source 2. If the power of the light source 2 is large, the gap can be appropriately increased, otherwise it can be reduced. The reason why the light source 2 and the through hole 15 are arranged at intervals is that the light source 2 will generate heat when emitting light. If the light source 2 continues to emit light, the heat generated will be continuously transferred to the light guide film 3, which will damage the light guide film 3 and thus its light guide performance in the long run. In other words, the gap between the light source 2 and the through hole 15 can be infinitely reduced. Specifically, when the heat generated by the light source 2 does not affect the light-guiding film 3, the light source 2 and the light-guiding film 3 can be infinitely close, and even the light source 2 can be placed in the through hole 15 as described in the above scheme. The specific installation method needs to be adjusted according to different design requirements and performance requirements. If the brightness requirement is not high, the light source 2 can be placed in the through hole 15. However, if the lighting effect of the earphone is required to be high and the brightness requirement is high, the power of the selected light source 2 must be relatively large. In this case, the light source 2 cannot be set too close to the light-guiding film 3, because the light emitted by the high-power light source 2 is brighter and can be well diffused to the light-guiding film 3 through the side wall of the through hole 15. Therefore, when the light can be well diffused and utilized, the problem of heating safety needs to be considered to avoid accidental burning.

[0034] Preferably, the light-blocking film 5 is sealed on the side of the through hole 15 away from the light source 2, and the upper and lower ends of the through hole 15 are open. The light emitted by the light source 2 enters from the lower side. In order to more effectively diffuse the light source 2 from the side wall of the through hole 15 to the light-guiding film 3, the light-blocking film 5 is directly sealed at the upper end of the through hole 15, which is equivalent to sealing the through hole 15 into a semi-open form. This can most effectively prevent light from passing through the upper end of the through hole 15 directly to the light-emitting surface 1011 of the shell 1, and such a setting of the light-blocking film 5 will be more stable and reliable, making the entire light-guiding film group integrated.

[0035] It is worth mentioning that the light-guiding film group consisting of the light-guiding film 3, the reflective film 4 and the light-blocking film 5 can be integrally formed in the production process. This can reduce the assembly steps of the light-guiding film group when assembling the earphones, save assembly time, and at the same time ensure the reliability and stability of the entire light-guiding film group.

[0036] At the same time, the materials of the light-guiding film 3, the light-reflecting film 4 and the light-blocking film 5 are selected as follows: the light-guiding film 3 is made of PC (polycarbonate) or PMMA (polymethyl methacrylate), the light-reflecting film 4 is made of PET (polyethylene terephthalate), and the light-blocking film 5 is also made of PET. PC material is a high-performance engineering plastic with many excellent properties, such as: PC material has high strength and rigidity, much higher than ordinary plastics such as ABS and PVC, which makes PC an ideal choice for manufacturing parts requiring high durability and impact resistance; PC material performs well at high temperatures and can withstand temperatures up to 160°C (290°F). If the light guide film 3 is made of PC material, the light source 2 can be preferably placed in the through hole 15 to ensure that the light can be effectively diffused; PC material also has good transparency and glossiness, and can be modified to obtain different colors and surface effects; in addition, PC material has good wear resistance and good processability. The wear resistance enables it to resist friction and wear to a certain extent, and the processability enables it to be manufactured into products of various shapes and sizes by injection molding, extrusion, blow molding and other methods, which can well adapt to the use requirements of small electronic devices such as headphones; at the same time, PC material also has good sound absorption performance, and can be used to manufacture products such as sound insulation boards and shock absorbers to reduce noise transmission. The light guide film 3 made of PC material can play a good sound insulation role to prevent the headphones from making sounds from the light outlet surface 1011 of the shell 1.

[0037] Compared with PC materials, PMMA materials are easy to process, highly transparent, light and strong. PMMA materials can be processed in many ways. They can be processed into acrylic products by PMMA plastic molding methods such as blow molding and extrusion, and can be cut, drilled, hot bent, polished, etc. by machines. They can also be bonded into acrylic products by chloroform or acrylic glue. PMMA materials are the most widely used and the best transparent materials in our lives. With its light transmittance of more than 92%, it is much stronger than glass. In some fields, PMMA is used to replace glass. Therefore, when the lighting effect of headphones is required to be high, light guide films made of PMMA materials can be used first.

[0038] PET material is a milky white or light yellow highly crystalline polymer with a smooth and shiny surface, good creep resistance, fatigue resistance, friction resistance and dimensional stability, low wear and high hardness, and the greatest toughness among thermoplastics: good electrical insulation performance, and little effect of temperature. The light-blocking film 5 is made of PET material, and the degree of light transmittance of the light source 2 can be adjusted by adjusting the color of the light-blocking film 5. The reflective film is made of white PET material, which can achieve better light reflection effect, thereby improving the brightness of the light-emitting surface 1011.

[0039] At the same time, the light emitting surface 1011 of the shell 1 can also be made of transparent PC material or PMMA material with diffusion powder added, and the inside of the shell 1 can be sandblasted and atomized to ensure uniform light emission from the light emitting surface 1011 of the shell 1.

[0040] In some embodiments, the housing 1 includes a lower housing 102 and an upper housing 101, the upper housing 101 is detachably mounted on the lower housing 102, the light source 2 is mounted on the lower housing 102 and emits light toward the upper housing 101, and the reflective film 4, the light guide film 3, and the light blocking film 5 are sequentially mounted between the light source 2 and the upper housing 101. The upper housing 101 and the lower housing 102 can be connected by snap-fitting or by fastening with screws, so that the two components can be easily disassembled and the internal parts can be easily maintained and repaired. The lower shell 102 is mainly used to install some other internal components such as the main control board 14, while the upper shell 101 is mainly used to install the light-guiding film group. A cavity is opened in the upper shell 101 relative to the light source 2, and the entire light-guiding film group is embedded in the cavity, which plays a role in stabilizing the installation of the light-guiding film group. At the same time, since the cavity is opened on the upper shell 101, the shell wall of the upper shell 101 can be designed to be relatively thin to improve its light transmittance.

[0041] Furthermore, the lower shell 102 includes a horizontal portion 1021, and a head portion 1022 and a tail portion 1023 protruding from both ends of the horizontal portion 1021 in a direction away from the upper shell 101, and an ear clamping position 1024 that can be clamped on the ear is defined between the head portion 1022 and the tail portion 1023. When the earphone is clamped on the ear through the ear clamping position 1024, the head portion 1022 is located on the inner side of the ear and the tail portion 1023 is located on the outer side of the ear. Therefore, a sound outlet hole 6 needs to be opened on the head portion 1022 corresponding to the inner side of the ear. At the same time, an installation cavity is opened inside the head 1022, and a magnet 10, a speaker 11, a battery 12, and a charging pin 7 are installed in the installation cavity. The specific installation positions are as follows: the magnet 10 is installed at the bottom of the installation cavity, and is used to be magnetically fixed to the earphone box. The speaker 11 is installed above the magnet 10. The speaker 11 needs to be connected to the sound outlet 6 so that the sound of the speaker 11 can be transmitted to the ear through the sound outlet 6. The battery 12 is installed above the speaker 11. The battery 12 is mainly used to provide power support for other components. Part of the charging pin 7 is exposed on the head 1022, and the charging pin 7 is connected to the battery 12 through a guide plate, so as to charge the battery 12.

[0042] It should be noted that the sound hole 6 is arranged at a position diagonally below the side of the head portion 1022 away from the tail portion 1023 . This position allows the sound hole 6 to be relatively closer to the inside of the ear, ensuring that the ear can clearly hear the sound emitted by the earphone through the sound hole 6 .

[0043] In addition, a sound leakage hole 8 is provided on one side of the head 1022 near the tail 1023. The sound leakage hole 8 is located in the ear clamping position 1024. The sound leakage hole 8 allows air to flow freely in the speaker 11 to prevent pressure accumulation and change in sound quality. The sound leakage hole 8 can also produce better sound quality and bass effect. A waterproof film is also integrated on the sound leakage hole 8 to improve the waterproof ability of the sound leakage hole 8, while making the sound quality clearer and the bass effect unaffected.

[0044] Preferably, a bracket 9 is installed in the horizontal portion 1021, and a main control board 14 is installed on the bracket 9. The light source 2 is arranged above the main control board 14 and connected to the main control board 14. The main control board 14 can control the light source 2 to emit light in the form of a marquee or in the form of breathing. In this scheme, the bracket 9 plays the role of fixing the main control board 14. The main control board 14 is mainly used to control the light emission form of the light source 2. The main control board 14 is also electrically connected to the speaker 11, and the sound and light synchronization control is realized by synchronously controlling the light source 2 and the speaker 11. Specifically, the lighting effects required to be presented by the headphones in different application scenarios are different. In order to better match the headphones with the current usage scenario, it is necessary to control the light emission form of the light source 2 through the main control board 14, such as controlling the light source 2 to display light in a wave-like manner, which can be applied to the seaside or a more romantic scene; or controlling the light source 2 to be presented in the form of one breath, so that the light emission rhythm of the light source 2 can follow the user's breathing frequency, which can be applied to sports scenes, giving users a smart interactive and novel use experience.

[0045] At the same time, a microphone 13 for receiving sound is also provided on the main control board 14 to realize the combination of receiving sound and emitting sound. The position of the microphone 13 needs to be closer to the mouth to improve the quality of receiving sound. In addition, the microphone 13 can obtain voice information to switch the lighting effect, that is, the user sends a lighting switching command, and transmits the signal to the main control board 14 through the microphone 13. After receiving the corresponding command signal, the main control board 14 sends the corresponding lighting command to the light source 2. After receiving the corresponding lighting command, the light source 2 emits light according to the command mode.

[0046] Based on the solution of providing a number of evenly spaced concave dots 301 on the light guide film 3, when the earphones need to present different lighting effects, a shading piece with a hollow pattern can be provided on the upper shell 101. For example, if the company's logo needs to be displayed, a logo pattern can be hollowed out on the shading piece so that only the hollowed-out position of the shading piece can transmit light. In this way, the surface light source formed on the light guide film 3 that transmits through the shading piece is the luminous logo. Of course, the pattern hollowed out on the shading piece is not limited to a logo, but can also be text or other shapes, which will not be elaborated here.

[0047] Specifically, the shading member can be a shading film. In addition to setting a shading member on the upper shell 101, the shading effect can be achieved by silk-screening black on the upper shell 101, such as blocking the middle area or other areas of the upper shell 101 to achieve a local luminous effect.

[0048] Optionally, the light source 2 is an RGB lamp bead, at least two of which are provided, and each of which is evenly spaced. The number of RGB lamp beads provided is not fixed, and can be adjusted according to different lighting requirements, such as providing three RGB lamp beads, and respectively located at the front, middle and rear positions of the light guide film 3, so that the light emitted by the RGB lamp beads can be diffused to every position of the light guide film 3.
