Referring to fig. 1 and 5, an external earphone 10 according to one embodiment of the present application is mainly composed of a lower cover 11, a bass intensifying apparatus 12, a horn 13, and an upper cover 14. The lower cover 11 has an accommodating space 111, and the bass enhancement device 12 is disposed in the accommodating space 111 of the lower cover 11. The bass enhancement device 12 has a speaker accommodating cavity 123 and a sound guiding channel 125, and the speaker 13 is disposed in the speaker accommodating cavity 123 of the bass enhancement device 12, and divides the speaker accommodating cavity into a front cavity 1231 and a rear cavity 1232. The upper cover 14 covers the upper end of the bass enhancement apparatus 10 to close the upper part of the rear chamber 1232 and the sound guide passage 125 (see fig. 5). The bass enhancement device 12 is provided with a horn sound outlet 124 communicating with the front chamber 1231 and a bass sound outlet 126 communicating with the sound guide passage 125 at a position facing the ear when the headphone 10 is worn, and the lower cover 11 is provided with a through hole 112 corresponding to the horn sound outlet 124 and the bass sound outlet 126. The sound emitted from the front cavity 1231 by the speaker 13 is guided out from the speaker sound outlet 124, and the bass sound generated from the rear cavity 1232 by the speaker 13 is guided out from the bass sound outlet 126 through the sound guiding channel 125 and overlapped with the bass sound guided out from the speaker sound outlet 124, so as to generate a superposition effect and enhance the bass sound effect of the open-type earphone 10.

Referring specifically to fig. 2 and 3, the bass enhancing apparatus 12 includes a housing 121 and an annular wall 122 formed inside the housing 121, the annular wall 122 dividing an internal space of the housing 121 into two portions independent of each other. That is, the annular wall 122 is eccentrically disposed in the housing 121, and surrounds a portion of the inner side surface of the housing 121 to form the horn receiving cavity 123, and the sound guide channel 125 is formed between the annular wall 122 and the housing 121. The annular wall 122 has a step 1221 formed on an inner side surface thereof, and the horn 13 is supported and mounted on the step 1221 in a manner that the diaphragm 131 faces downward, so as to divide the horn accommodating chamber 123 into a front chamber 1231 below the horn diaphragm 131 and a rear chamber 1232 above the horn 13 (see fig. 5). A notch 1222 is formed in the upper end of the annular wall 122 to communicate the rear chamber 1232 with the sound guide channel 125. As further shown in fig. 2 and 3, the bass enhancement apparatus 12 is also provided with a horn sound outlet 124 and a bass sound outlet 126, which are disposed adjacent to each other at a position where the housing 121 faces the ears. The horn outlet 124 communicates between the front chamber 1231 and the outside of the housing 121, and guides out the sound generated in the front chamber 1231 by the horn 13. The bass sound outlet 126 communicates between the sound guide passage 125 and the outside of the housing 121, and guides the bass sound generated by the speaker 13 in the rear chamber 1232 out through the sound guide passage 125. Further, an inner ear-hanging connection portion 128 is disposed outside the casing 121 of the bass enhancing apparatus 12, and a wire hole 127 is further disposed in the casing 121 corresponding to the inner ear-hanging connection portion 127 for leading a wire passing through the inner ear-hanging connection portion 128 into the casing 121 to connect with the loudspeaker 13. Correspondingly, the lower cover 11 is provided with an external ear connection portion 113 for the internal ear connection portion 128 to penetrate through, and the internal ear connection portion 128 and the external ear connection portion 113 can be used for penetrating through a wire and connecting the external earphone 10 to a corresponding earphone device.

Referring further to fig. 4 in conjunction with fig. 5, the upper cover 14 covers the upper end of the bass enhancing apparatus 12 through a positioning structure cooperating with the bass enhancing apparatus 12, and closes the upper portion of the rear cavity 1232 and the sound guide channel 125, so as to guide out the bass sound in the rear cavity 1232 from the bass sound outlet 126 as much as possible. As shown in fig. 4 and fig. 5, a ring of annular ribs 141 is formed on the lower surface of the upper cover 14 for being inserted into the upper end of the horn receiving cavity 123 of the bass enhancing device 12. The lower surface of the upper cover 14 is further provided with positioning ribs 142 at the outer sides of the annular ribs 141 for being engaged and positioned with

positioning grooves

1211 and 1223 respectively formed at the upper ends of the casing 121 and the annular wall 122 of the bass intensifying apparatus 12. Further, three tuning holes 144 penetrating the upper and lower surfaces are formed in the middle of the upper cover 14, and a mounting groove 143 is formed in the tuning hole area of the lower surface for attaching a tuning net (not shown) to cover the tuning holes 144. The three tuning holes 144 communicate the rear cavity 1232 with the outside for adjusting the air output of the horn 13, thereby adjusting the bass effect of the horn 13. The tuning nets with different densities are attached to the inner sides of the three tuning holes 144, the air output of the rear cavity 1232 can be adjusted, the density of the tuning nets is small, the air output is large, and bass is heavy.

The external earphone 10 according to the above embodiment of the present application uses the special bass enhancement device 12 to lead out the bass generated by the speaker 13 in the rear cavity 1232 from the bass outlet 126 through the sound leading channel 125, and to overlap the bass led out from the speaker outlet 124, so as to generate a superposition effect, and enhance the bass effect of the open earphone 10. The external earphone 10 according to the above-described embodiment of the present application may be applied to various external earphone application scenarios, such as bluetooth earphones, bluetooth glasses, and the like.
