[0039] REFERENCE Figures 1 to 8 As shown in the figure, a head-mounted earphone with a reflection sound cone comprises a headgear 1, ear cover assemblies 2 connected at both ends of the headgear 1, and a sound emitting unit 3, wherein the ear cover assembly 2 comprises an earphone main body 21a and the sound emitting unit 3, and the sound emitting unit 3 comprises a loudspeaker front cavity support 301, a bass loudspeaker 302, a PCBA main board 303, and a loudspeaker rear cavity support 304; the bass loudspeaker 302 is arranged between the loudspeaker front cavity support 301 and the loudspeaker rear cavity support 304; the PCBA main board 303 is arranged on the loudspeaker rear cavity support 304; the inside center of the loudspeaker front cavity support 301 is provided with a reflection sound cone 305, which is coaxially arranged with the bass loudspeaker 302 and extends outward towards the bass loudspeaker 302. In this embodiment, the reflection sound cone 305 is in the shape of a whole cone, with a smooth transition at the tapered tip, so that sound waves can be diffused in all directions around the cone.

[0040] As Figure 7As shown, the horn front cavity support 301 in the embodiment includes an annular base plate 311, and a connecting plate 312 connected to the surface of the annular base plate 311, the connecting plate 312 is provided with four, arranged at intervals, one end of the connecting plate 312 is connected to the annular base plate 311, and the other end converges towards the shaft and is connected as one. The reflecting sound cone 305 is arranged at the end of the connecting plate 312 that is integrated, and the reflecting sound cone 305 extends outward in the direction of the bass horn 302. Among them, the end of the reflecting sound cone 305 connected with the connecting plate 312 is integrally formed and extends in the direction of the bass horn 302 to form an integrated structure. The integrally formed reflecting sound cone 305 can be formed by cold pressing during processing, and the reflecting sound cone 305 is formed into a cylindrical body by cold pressing from the end connected to the connecting plate 312. In other embodiments, the reflecting sound cone 305 can also be in a split structure and is fixedly installed at the converging part of the connecting plate 312. The reflecting sound cone 305 is in the shape of a cone, and when its surface diffuses the sound waves transmitted from the bass horn 302, it can more uniformly radiate the sound waves to the surrounding.

[0041] The horn rear cavity support 304 is assembled as one with the horn front cavity support 301, the bass horn 302, and the PCBA mainboard 303 are assembled therein to form a sound unit 3. The horn front cavity support 301 is fixed on the earphone main body inner shell 212, the earphone main body outer shell 211 and the earphone main body inner shell 212 can be connected by screws to form an earphone main body 21a of the ear cover assembly 2, and the sound unit 3 is assembled in the containing frame 213 of the earphone main body inner shell 212.

[0042] A reflecting sound cone 305 is arranged at the center of the inner side of the horn front cavity support 301, the reflecting sound cone 305 protrudes in the direction of the bass horn 302, the reflecting sound cone 305 is in the shape of a cone and coaxial with the center line of the bass horn 302. The bass horn 302 sounds, and the sound waves propagate forward, when the sound waves at the center pass through the reflecting sound cone 305, they are reflected by the surface of the reflecting sound cone 305 and spread to the surrounding. The surface of the containing frame 213 is distributed with sound holes 2131 for passing sound waves, the sound waves reflected by the conical surface of the reflecting sound cone 305 spread to the surrounding and pass out of the sound holes 2131. The sound is reflected by the surface of the reflecting sound cone 305 and spreads to the surrounding 360 degrees through the reflecting sound cone 305, which reduces the impact of the sound wave center on the eardrum when it propagates to the eardrum, making the sound heard more soft. The sound waves emitted by the bass horn 302 spread to the surrounding in the direction of the reflecting sound cone 305, and in the process of propagating into the human ear, the low-frequency sound waves can be transmitted inward along the ear canal wall, reducing the direct impact on the center part of the eardrum of the human ear, making the sound heard more soft.

[0043] Specifically, the bass speaker 302 vibrates to emit sound waves, and the sound waves propagate towards the front cavity support 301. The sound waves located at the periphery are reflected by the outer periphery of the reflection cone 305, and then pass through the sound holes 2131 of the accommodating frame 213 to enter the user's ear canal. Another part of the sound waves located at the center is reflected by the surface of the reflection cone 305, and then radiates to the periphery through the conical surface of the reflection cone 305. A part of the sound waves directly passes through the sound holes 2131 of the accommodating frame 213. The reflection cone 305 is arranged to make the bass sound emitted by the bass speaker 302 enter the ear canal in a way of being diffused to the periphery with the reflection cone 305 as the center. The sound holes of the accommodating frame 213 are arranged in a ring shape with the reflection cone 305 as the center, and no sound hole is arranged at the center of the accommodating frame 213. In this way, the bass sound waves are transmitted along the surface of the ear canal more, and the direct radiation to the center of the eardrum is reduced, so that the listening experience is more comfortable.

[0044] As Figure 6 , the edge of the front cavity support 301 extends towards the rear cavity support 304 to form a screw column 313, and the edge of the rear cavity support 304 is provided with a connecting lug 341 corresponding to the position of the screw column 313. A through hole is arranged on the connecting lug 341, and the rear cavity support 304 is connected to the front cavity support 301 by screwing a screw through the through hole. An installation column 342 is arranged on the rear side of the rear cavity support 304, and the PCBA main board 303 can also be fixed and installed on the installation column 342 by screwing.

[0045] In the assembly process, the front cavity support 301 is first glued to the accommodating frame 213 of the earphone main body inner shell 212, and then the bass speaker 302 is glued to the front cavity support 301. Then, the rear cavity support 304 is attached to the front cavity support 301, and the assembly of the front cavity support 301 and the rear cavity support 304 is completed by screwing a screw through the through hole of the connecting lug 341 and screwing it on the screw column 313. After the rear cavity support 304 is assembled on the front cavity support 301, the edge of the bass speaker 302 is clamped between the front cavity support 301 and the rear cavity support 304. Then, the PCBA main board 303 is assembled on the installation column 342 by screwing, and the lead wire of the bass speaker 302 is welded on the corresponding pad of the PCBA main board 303. Finally, the earphone main body outer shell 211 is connected to the earphone main body inner shell 212 by screwing and gluing, and the assembly of the ear cover 2 is completed. Embodiment

[0046] Referring to Figures 1-14As shown, the second embodiment is further improved in structure based on the first embodiment. The earphone comprises a headgear 1, ear cover assemblies 2 connected at both ends of the headgear 1, and a sound emitting unit 3. The ear cover assembly 2 comprises an earphone main body 21a and the sound emitting unit 3. The earphone main body 21a is connected to the sound emitting unit 3 through a connecting arm 21b. The sound emitting unit 3 is located at the center of the ear cover assembly 2. The sound emitting unit 3 and the inner side periphery of the ear cover assembly 2 form an open release hole 201 that penetrates the ear cover assembly 2 axially. The release hole 201 is in the shape of a curved U. Correspondingly, a rear cover 202 for covering the release hole 201 is detachably arranged at the rear side of the ear cover assembly 2. The rear cover 202 is adapted to the shape and size of the release hole 201.

[0047] Referring to Figure 1 , Figure 2 In use, the headgear is worn on the head of a user, and the ear cover assemblies 2 cover the user's ears. When the rear cover 202 is assembled on the ear cover assembly 2, the rear cover 202 covers the release hole 201, so that when the ear cover assembly 2 wraps the user's ears, an enclosed listening space is formed between the ear cover assembly 2 and the user's ear canal, sound is transmitted to the eardrum, and the user's listening immersion is improved. After the rear cover 202 is assembled, the sound insulation effect is achieved, and the rear cover 202 can be assembled to prevent sound leakage when privacy protection is needed. After the rear cover 202 is assembled, it is suitable for use in Internet cafes, e-sports, professional audio production, and other occasions.

[0048] When the earphone is used for a long time, the enclosed listening space formed between the ear cover assembly 2 and the user's ears can cause discomfort. At this time, the rear cover 202 is removed, the listening space is connected to the outside world, the sound pressure is released, and the discomfort is improved. After the rear cover 202 is opened, the user can not only hear the sound emitted by the earphone, but also hear the sound of the surrounding environment. This is suitable for scenarios that require timely perception of the surrounding environment, such as outdoor activities. After the rear cover 202 is removed, the inner side of the ear cover assembly 2 is connected to the outside world through the release hole 201, allowing air to circulate, the ear to cool down quickly, and not to sweat easily. More sound waves escape from the back of the sound emitting unit 3, reducing the reflection and echo of sound around the ear, and the sound is natural.

[0049] Referring to Figures 3 to 4As shown, the earphone body 21a includes an earphone body outer shell 211 and an earphone body inner shell 212, and a space enclosed between the earphone body outer shell 211 and the earphone body inner shell 212 is arranged to accommodate the sound unit 3.

In other embodiments, the rear cover outer shell 203 and the rear cover inner shell 204 can also be connected by other forms, such as bonding, screw connection, etc. A first magnetic attraction magnet 205 is arranged on the rear cover inner shell 204, and a second magnetic attraction magnet 206 is arranged in a magnet slot 207 of the earphone body outer shell 211. The first magnetic attraction magnet 205 and the second magnetic attraction magnet 206 are opposite to each other, and the polarities of the opposite end faces are opposite, so that when the first magnetic attraction magnet 205 approaches the second magnetic attraction magnet 206, the first magnetic attraction magnet 205 is attracted by the magnetic attraction force, thereby attracting and fixing the ear cover rear cover 202 to the outside of the earphone body outer shell 211, realizing the assembly of the ear cover rear cover 202. The first magnetic attraction magnet 205 and the second magnetic attraction magnet 206 are used to install the ear cover rear cover 202 by mutual attraction, and the user can more conveniently disassemble and assemble the ear cover rear cover 202 from and on the earphone body outer shell 211. Among them, the ear cover rear cover 202 is arranged to include the rear cover outer shell 203 and the rear cover inner shell 204, which is used to assemble the first magnetic attraction magnet 205 inside the ear cover rear cover 202 without exposure when the rear cover outer shell 203 and the rear cover inner shell 204 are assembled to form the ear cover rear cover 202.

[0050] In other embodiments, the ear cover rear cover 202 and the ear cover assembly 2 can also be fixedly connected by buckling connection, for example, a buckle is arranged on the earphone body outer shell 211, a buckle hole or a buckle slot is arranged on the ear cover rear cover 202, and the ear cover rear cover 202 and the earphone body outer shell 211 are detachably connected by the buckle. The ear cover rear cover 202 and the earphone body outer shell 211 can also be detachably connected by screw connection, for example, a screw hole is arranged on the outside edge of the earphone body outer shell 211, a through hole for passing through a screw is arranged on the ear cover rear cover 202 at a position corresponding to the screw hole, and a locking screw is threadedly connected to the screw hole of the earphone body outer shell 211 after passing through the through hole of the ear cover rear cover 202, thereby completing the connection of the ear cover rear cover 202 and the ear cover assembly 2. The connection between the ear cover rear cover 202 and the ear cover assembly 2 can be selected according to actual use requirements.

[0051] Referring to Figures 9 to 14 As shown, the ear cover assembly 2 and the headgear 1 are connected by the ear cover connecting piece 11.

[0063] Reference Figures 17 to 23As shown, in this embodiment, based on the above embodiments one, two and / or three, the sound unit 3 can move relative to the earmuff assembly 2, so that the sound units 3 located at both ends of the headband 1 can adjust their relative distance, thereby adjusting the distance between the sound unit 3 and the ear canal when worn.

[0064] like Figure 17 As shown, the sound unit 3 also includes a speaker component upper shell 307 and a speaker component bottom shell 308. The earphone main body outer shell 211 is connected to the speaker component upper shell 307 via a first connecting arm 215, and the earphone main body inner shell 212 is connected to the speaker component bottom shell 308 via a second connecting arm 216. The mid-high frequency speaker 306 is mounted on the speaker mounting base 314, and the woofer 302 is mounted on the annular base 311 of the speaker front cavity bracket 301. Then, the speaker rear cavity bracket 304 is fixedly connected to the speaker front cavity bracket 301. The PCBA main board 303 is mounted on the rear side of the speaker rear cavity bracket 304, and the leads of the mid-high frequency speaker 306 and the woofer 302 are soldered to the PCBA main board 303. After assembling the speaker front cavity bracket 301 and the speaker rear cavity bracket 304, the sound unit 3 is assembled on the front and rear speaker component upper shells 307 and speaker component bottom shells 308.

[0065] Reference Figure 17 and Figure 18 The upper shell 307 of the speaker component is slidably connected to the first connecting arm 215, allowing the upper shell 307 to slide relative to the first connecting arm 215, thereby adjusting the relative position of the two upper shells 307 of the speaker components located at both ends of the headband 1, and thus adjusting the distance between the sound unit 3 and the ear canal. A mounting hole 217 is provided at the contact point between the first connecting arm 215 and the upper shell 307 of the speaker component, and a ball-head plunger 218 is provided in the mounting hole 217. A stop spring 371 is provided on the upper shell 307 of the speaker component. The ball-head plunger 218 contacts and cooperates with the stop spring 371, allowing the upper shell 307 of the speaker component to slide relative to the end of the first connecting arm 215. The ball-head plunger 218 presses against the stop spring 371 to fix the position of the sound unit 3, thereby adjusting the distance of the sound unit 3 relative to the ear. By adjusting the distance of the sound unit 3 relative to the ear, users can experience different listening effects.

[0066] like Figure 19 The diagram shown illustrates the position of the ball plunger 218 mounted on the first connecting arm 215 in this embodiment. Specifically, the end of the first connecting arm 215 that connects to the upper housing 307 of the horn component is provided with an assembly hole 217, in which the ball plunger 218 is assembled.

[0067] Reference Figure 20As shown, specifically, the ball head plunger 218 comprises a plunger body 2181, a spring 2182 and a plunger rod 2183, the plunger body 2181 is provided with a semi-closed plunger groove 2184, one end of the plunger rod 2183 extends into the plunger groove 2184 and forms a hemispherical end 2185 at the outer end, the slot opening of the plunger groove 2184 extends radially inwardly and is provided with a radial inner edge 2186, the inner side of the hemispherical end 2185 forms a radial outer edge 2187, and the spring 2182 is arranged in the plunger groove 2184 and abuts against the bottom wall of the plunger groove 2184 and the inner side of the hemispherical end 2185 at both ends. Through the cooperation of the radial outer edge 2187 and the radial inner edge 2186, the hemispherical end 2185 and the plunger rod 2183 cannot run out of the plunger groove 2184. In other embodiments, the end of the plunger rod 213 can also be provided as a spherical end with a diameter greater than the inner diameter of the plunger groove slot opening to prevent the plunger rod 2183 from running out of the plunger groove 2184.

[0068] Referring to Figure 21 and Figure 22 As shown, the surface of the gear elastic sheet 371 is spaced apart and provided with positioning grooves 372 adapted to the surface of the hemispherical end 2185. The spring 2182 pushes the hemispherical end 2185 of the plunger rod 2183 to extend outwardly, and when the hemispherical end 2185 of the plunger rod 2183 abuts against the gear elastic sheet 371 between the positioning grooves 372, at this time the plunger rod 2183 and the spring 2182 are compressed into the plunger groove 2184, and the sound unit 3 can still be moved; when the hemispherical end 2185 of the plunger rod 2183 abuts against the positioning groove 372, the spring 2182 pushes the plunger rod 2183 to extend and clamp the gear elastic sheet 371, thereby fixing the position of the sound unit 3.

[0069] Since the hemispherical end 2185 of the plunger rod 2183 abuts against the positioning groove 372 of the gear elastic sheet 371 to complete the clamping and fixing of the sound unit 3, the pressure is mainly provided by the elastic force of the spring 2182. When the force for moving the sound unit 3 is relatively large and can overcome the elastic force of the spring 2182, the hemispherical end 2185 of the plunger rod 2183 moves inwardly into the plunger groove 2184 through the extrusion of the gear elastic sheet 371, and the spring is compressed to accumulate elastic force, the position of the sound unit 3 is continuously moved, so that the sound unit 3 can move relative to the first connecting arm 215, and after the sound unit 3 moves to the required position, the positioning groove 372 corresponds to the plunger rod 2183, the spring 2182 pushes the plunger rod 2183 to extend outwardly and abut against the gear elastic sheet 371, thereby realizing the adjustment of the position of the sound unit 3.

Specifically, when connecting the first connecting arm 215 to the upper shell 307 and the lower shell 308 of the speaker component, the locking flange 2151 of the first connecting arm 215 first engages with the upper shell 307 of the speaker component, and then the lower shell 308 is assembled onto the upper shell 307. After assembly, the first connecting arm 215 cannot be separated from the mounting groove 309.

[0071] like Figure 22 As shown, the back of the shift spring 371 has inwardly extending metal barbs 373. These barbs 373 penetrate the rubber surface of the speaker component upper housing 307, thereby fixing the shift spring 371 to the speaker component upper housing 307. This prevents the shift spring 371 from detaching from the surface of the speaker component upper housing 307 during the movement of the sound unit 3. By fixing the shift spring 371 by inserting the barbs 373 into the surface of the mounting groove 309 of the speaker component upper housing 307, pressure can be applied using a tool to force the barbs 373 of the shift spring 371 into the surface of the mounting groove 309, resulting in a secure connection and simplified manufacturing process.

[0072] During assembly, the mid-high frequency speaker 306 and the woofer 302 are respectively mounted on the speaker mounting base 314 and the annular chassis 311.

Then, the speaker front cavity bracket 301 and the speaker rear cavity bracket 304 are installed together into the speaker component bottom shell 308. When installing the speaker front cavity bracket 301 and the speaker rear cavity bracket 304 into the speaker component bottom shell 308, they can be fixed with glue. Press the stop spring 371 into the speaker component upper shell 307 to make the stop spring 371 and the speaker component upper shell 308 firmly connected. The ball-head plunger 218 is fitted into the mounting hole 217 of the first connecting arm 215, and then the first connecting arm 215 is inserted into the mounting groove 309. The locking flange 2151 of the first connecting arm 215 is engaged in the mounting groove 309, thus completing the connection between the first connecting arm 215 and the sound unit 3. Alternatively, the end of the first connecting arm 215 can be placed in the mounting groove 309 on the upper shell 307 of the speaker component, and then the upper shell 307 of the speaker component is assembled. The upper shell 307 of the speaker component is connected to the bottom shell 307 of the speaker component with glue, thereby positioning the first connecting arm 215 in the mounting groove 309. Finally, the earphone body shell 211 and the earphone body inner shell 212 are assembled into one piece using screws.
