For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0037] As Figure 1 shown, an ear shell unit provided by an embodiment of the present utility model, wherein the ear shell unit can be applied to a headphone. Among them, the headphone can be a head-mounted headphone, an in-ear headphone, or an ear-hook headphone; the headphone can be configured with a call noise reduction function and / or an artificial intelligence noise reduction function; at the same time, it can also be configured with functions such as stereo surround.

[0038] Combined with Figure 2 and Figure 3 , the ear shell unit includes an ear shell 100, a light source assembly 200, a display assembly 300, and a light leakage prevention buffer member 400.

[0039] Combined with Figure 3 and Figure 4 , the ear shell 100 is provided with a light passing port 110.

[0040] Specifically, the ear shell 100 is a hollow structure, and the ear shell 100 is provided with a light passing port 110 communicating with its internal space. The ear shell 100 is used to protect the components arranged inside it.

[0041] Combined with Figure 4 and Figure 5, the light source assembly 200 includes a circuit board 210 disposed inside the ear shell 100 and opposite to the light passing port 110, and a light source 220 disposed on a side of the circuit board 210 close to the light passing port 110. The light source 220 is located within the light passing port 110.

[0042] It can be understood that the light source 220 is disposed on the circuit board 210, and the circuit board 210 can distribute electric energy to the light source 220, so that the light source 220 emits light. Among them, the source of electric energy can be an external power source or a battery disposed within the ear shell unit. The light source 220 can be an LED lamp. In addition, since the light source 220 is located within the light passing port 110, the light emitted by the light source 220 can propagate outward through the light passing port 110.

[0043] In some other embodiments, the light source 220 is located inside the light passing port 110 and is oriented towards the light passing port 110. In other words, the light source 220 is located inside the ear shell 100 and does not extend into the light passing port 110. Similarly, the light emitted by the light source 220 can propagate outward through the light passing port 110.

[0044] Combined Figure 3 with Figure 4 , the display assembly 300 includes a light guiding member 310 covering the light passing port 110 and located outside the light source 220.

[0045] It can be understood that the light guiding member 310 can be a semi-transparent member or a fully transparent member. The light guiding member 310 is made of a light guiding material and can conduct light. The light emitted by the light source 220 can enter the light guiding member 310 and exit from the light guiding member 310. Among them, at least a part of the light guiding member 310 can be set in the shape of a LOGO. In this way, the LOGO can achieve a light emitting effect and improve the viewing effect of users.

[0046] Furthermore, the number of the light sources 220 is multiple, and the multiple light sources 220 are distributed within the light passing port 110, which can improve the uniformity of the display brightness of the light guiding member 310.

[0047] It should be noted that the circuit board 210 is disposed inside the ear shell 100 and opposite to the light passing port 110. The circuit board 210 can play a light shielding effect, preventing the light emitted by the light source 220 from directly propagating to the side of the circuit board 210 opposite to the light source 220, thereby reducing the risk of light leakage caused by the light passing through other gaps on the ear shell 100 and emitting out.

[0048] Furthermore, the light leakage prevention buffer member 400 is disposed on the side of the circuit board 210 close to the light passing port 110, and the light leakage prevention buffer member 400 abuts against the inner wall of the ear shell 100. Among them, the light leakage prevention buffer member 400 surrounds the light source 220 and is arranged around the inner end of the light passing port 110. In this way, the light leakage prevention buffer member 400 can seal the gap between the circuit board 210 and the ear shell 100, thereby reducing the risk of light leakage caused by light diffusing into the ear shell 100 through this gap and then passing through other gaps on the ear shell 100 and emitting out. Among them, the light leakage prevention buffer member 400 can be made of light-impermeable materials or can be coated with a light-impermeable coating on its surface, such as a black coating.

[0049] In addition, the light leakage prevention buffer member 400 is made of an elastic material, such as silica gel, rubber or foam, and can also play a buffering effect, reducing the risk of damage caused by hard collision between the circuit board 210 and the ear shell 100 due to the vibration of the ear shell unit.

[0050] As Figure 4 shown, further, the light leakage prevention buffer member 400 is provided with a first assembly hole, the circuit board 210 is provided with a second assembly hole 211 opposite to the first assembly hole, and the inner wall of the ear shell 100 is provided with a connecting column 140 passing through the first assembly hole and the second assembly hole 211; among them, the connecting column 140 is provided with an installation hole 141, and a fastener (not shown) passes through the installation hole 141 and abuts against the side of the circuit board 210 away from the light leakage prevention buffer member 400.

[0051] It can be understood that the connecting column 140 can simultaneously position the circuit board 210 and the light leakage prevention buffer member 400, and after the fastener passes through the installation hole 141 and abuts against the side of the circuit board 210 away from the light leakage prevention buffer member 400, the circuit board 210 and the light leakage prevention buffer member 400 can be fixed.

[0052] Among them, the fastener can be a bolt, and the installation hole 141 is a threaded hole.

[0053] Furthermore, in order to improve the positioning effect of the light leakage prevention buffer member 400 and the circuit board 210, a plurality of connecting columns 140 can be provided to jointly position the light leakage prevention buffer member 400 and the circuit board 210.

[0054] It should be noted that in other embodiments, the circuit board 210 can also be fixed to the ear shell 100 by means of a buckle.

[0055] Combined Figure 3 with Figure 4, in some embodiments, the light guide member 310 includes a main body portion 311 and a display portion 312 disposed on the main body portion 311. The main body portion 311 and the display portion 312 are integrally connected. The main body portion 311 covers the light passing port 110, and the display portion 312 protrudes from the side of the main body portion 311 away from the light source 220; the display assembly 300 further includes a light shielding member 320. The light shielding member 320 is disposed on the side of the main body portion 311 away from the light source 220, and the light shielding member 320 is provided with an avoidance opening 321 for the display portion 312 to pass through.

[0056] It can be understood that the display portion 312 can be set into different shapes as needed. For example, the display portion 312 can be set into a corresponding LOGO shape. The light emitted by the light source 220 can first enter the main body portion 311 and then be emitted through the display portion 312. Among them, since the light shielding member 320 is disposed on the side of the main body portion 311 away from the light source 220, and the display portion 312 can pass through the avoidance opening 321 on the light shielding member 320, the light shielding member 320 can shield the main body portion 311, and the display portion 312 is exposed. In this way, when the light source 220 emits light, the effect of the LOGO emitting light can be achieved.

[0057] It should be noted that the light shielding member 320 can be made of a light-impermeable material or a light-impermeable coating can be applied to its surface, such as a black coating, so as to achieve the light shielding effect.

[0058] Furthermore, at least a part of the display portion 312 passes out of the avoidance opening 321, and a light shielding layer is provided on the side of the display portion 312 away from the main body portion 311. In other words, the display portion 312 protrudes from the light shielding member 320, and the front surface 3121 of the display portion 312 is coated with a light shielding layer, such as a black coating. In this way, when the light source 220 emits light, the side surface 3122 of the part of the display portion 312 that passes out of the avoidance opening 321 can emit light, so that the light surrounds the headphone LOGO.

[0059] It should be noted that the wall of the avoidance opening 321 and the side wall of the display portion 312 can be attached together, so that it can prevent external pollutants from entering the avoidance opening 321 through the gap between the wall of the avoidance opening 321 and the side wall of the display portion 312. For example, the light guide member 310 can be made of an elastic material. After the display portion 312 of the light guide member 310 passes through the avoidance opening 321, it has an interference fit with the wall of the avoidance opening 321, so as to realize the sealing between the wall of the avoidance opening 321 and the side wall of the display portion 312. At the same time, this fitting method can also fix the light guide member 310 and the light shielding member 320 together.

[0060] Of course, in other embodiments, there can also be a certain gap between the wall of the avoidance opening 321 and the side wall of the display portion 312, which is convenient for the assembly of the light shielding member 320 and the light guide member 310.

[0061] As Figure 4 shown, further, the auricle 100 defines a first positioning groove 120. The first positioning groove 120 is located outside the light passing port 110 and is arranged around the outer end of the light passing port 110. The main body portion 311 is arranged in the first positioning groove 120, and the first positioning groove 120 is used for positioning the main body portion 311. Moreover, the main body portion 311 is arranged in the first positioning groove 120, and can also cover the light passing port 110, so that the light propagating outward through the light passing port 110 can be as much as possible injected into the main body portion 311, reducing the risk of light leakage caused by the light propagating outward through the light passing port 110 emitting from the side of the main body portion 311.

[0062] Furthermore, the auricle 100 further defines a second positioning groove 130. The second positioning groove 130 is located outside the first positioning groove 120 and is arranged around the outer end of the first positioning groove 120. The light shielding member 320 is arranged in the second positioning groove 130, and the second positioning groove 130 is used for positioning the light shielding member 320.

[0063] It should be noted that the light shielding member 320 is in sealing fit with the groove wall of the second positioning groove 130. That is, the light shielding member 320 abuts against the groove wall of the second positioning groove 130. Thus, when the light emitted by the light source 220 irradiates on the main body portion 311, the risk of light leakage caused by the light in the main body portion 311 propagating through the gap between the second positioning groove 130 and the light shielding member 320 can be reduced. Of course, the light shielding member 320 abutting against the groove wall of the second positioning groove 130 can also reduce the risk of external pollutants entering the interior of the auricle 100 through the gap between the light shielding member 320 and the groove wall of the second positioning groove 130, improving the waterproof and dustproof effects.

[0064] Wherein, a sealing glue can also be coated between the light shielding member 320 and the second positioning groove 130, so as to realize the fixation of the light shielding member 320 and the auricle 100.

[0065] In the ear shell unit of the present utility model, the light emitted by the light source 220 can enter the light guide member 310 and exit from the light guide member 310, improving the viewing effect of the user. In addition, the circuit board 210 is disposed inside the ear shell 100 and is disposed opposite to the light passing port 110. The circuit board 210 can achieve a light shielding effect, preventing the light emitted by the light source 220 from directly propagating to the side of the circuit board 210 opposite to the light source 220, thereby reducing the risk of light leakage caused by the light passing through other gaps on the ear shell 100. Moreover, the light leakage prevention buffer member 400 is disposed on the side of the circuit board 210 close to the light passing port 110, and the light leakage prevention buffer member 400 abuts against the ear shell 100. Among them, the light leakage prevention buffer member 400 surrounds the light source 220 and is disposed around the inner end of the light passing port 110. In this way, the light leakage prevention buffer member 400 can seal the gap between the circuit board 210 and the inner wall of the ear shell 100, thereby reducing the risk of light leakage caused by the light diffusing into the ear shell 100 through this gap and then passing through other gaps on the ear shell 100. In addition, the light leakage prevention buffer member 400 can also achieve a buffering effect, reducing the risk of damage caused by a hard collision between the circuit board 210 and the ear shell 100 due to the vibration of the ear shell unit.

[0066] The present utility model also provides a headset, including the ear shell unit of the above embodiment. Among them, the headset can be a head-mounted headset, an in-ear headset or an ear-hook headset; the headset can be configured with a call noise reduction function and / or an artificial intelligence noise reduction function; at the same time, functions such as stereo surround can also be configured.

[0067] The above-mentioned earphone has the earphone housing unit of the above-mentioned embodiment. In the earphone housing unit, a light source 220 is arranged on a circuit board 210, and the circuit board 210 can distribute electrical energy to the light source 220, so that the light source 220 emits light. Wherein, the light emitted by the light source 220 can enter the light guide member 310 and exit from the light guide member 310. Wherein, the light guide member 310 can be arranged in the shape of a LOGO. In this way, the LOGO can achieve a light-emitting effect and improve the viewing effect of users. In addition, the circuit board 210 is arranged inside the earphone housing 100 and is arranged opposite to the light passing port 110. The circuit board 210 can play a light-shielding effect, preventing the light emitted by the light source 220 from directly propagating to the side of the circuit board 210 opposite to the light source 220, thereby reducing the risk of light leakage caused by the light passing through other gaps on the earphone housing 100. And, a light-leakage prevention buffer member 400 is arranged on the side of the circuit board 210 close to the light passing port 110, and the light-leakage prevention buffer member 400 abuts against the earphone housing 100. Wherein, the light-leakage prevention buffer member 400 surrounds the light source 220 and is arranged around the inner end of the light passing port 110. In this way, the light-leakage prevention buffer member 400 can seal the gap between the circuit board 210 and the inner wall of the earphone housing 100, thereby reducing the risk of light leakage caused by the light diffusing into the earphone housing 100 through this gap and then passing through other gaps on the earphone housing 100. Wherein, the light-leakage prevention buffer member 400 can be made of a light-impermeable material, or an impermeable coating can be coated on its surface, such as a black coating. In addition, the light-leakage prevention buffer member 400 can also play a buffering effect, reducing the risk of damage caused by a hard collision between the circuit board 210 and the earphone housing 100 due to the vibration of the earphone housing unit.
