[0042] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the drawings and embodiments.
[0043] Please refer to Figures 1 to 9 , a compatible earphone, which includes: an earphone body 1. The earphone body 1 includes an earphone housing 11. A speaker 16 is provided inside the earphone housing 11. The earphone housing 11 is provided with a sound outlet portion 12 disposed opposite to the speaker 16. The sound outlet portion 12 is provided with a sound outlet hole 15; it further includes an in-ear structure 2. Refer to Figure 6 , Figure 7 ; The in-ear structure 2 includes a connecting member 22. One end of the connecting member 22 is detachably connected to the sound outlet portion 12, and the other end of the connecting member 22 is connected with an ear cap 21.
[0044] Preferably, when the connecting member 22 is connected to the sound outlet portion 12, the connecting member 22 covers the sound outlet hole 15 on the sound outlet portion 12.
[0045] In the use of this technical solution, the earphone body 1 can be used as an open earphone. When used as an open earphone, it can be combined with an ear hook, etc. In this embodiment, the combination with an ear hook 3 is adopted; when in use, the earphone body 1 is close to the external auditory canal, and the sound outlet portion 12 partially or completely covers the outer ear auricle; when the speaker 16 plays sound, the sound comes out from the sound outlet portion 12 and enters the ear along the auricle and the external auditory canal; at this time, the earphone body 1 and the in-ear structure 2 are in a separated state.
[0046] When used as in-ear headphones, the connecting member 22 is connected to the sound output portion 12. During use, the ear cap 21 is inserted into the ear. The speaker 16 inside the headphone body 1 emits sound, and the sound is introduced into the ear cap 21 through the sound output portion 12 and the connecting member 22 and then enters the ear. At this time, the sound output portion 12 can be separated from the outer ear auricle of the ear. The entire headphone can be supported by the friction force between the ear cap 21 and the external auditory canal.
[0047] Secondly, it should be noted that: a wireless device, a battery, etc. can be provided inside the headphone body 1, and the wireless device is connected to the internal control circuit board 110; the headphone body 1 can also be provided with a wire, and the wire is connected to the control circuit board 110; these structures are all existing and can be set according to needs. Details are not described here.
[0048] Thirdly, there are various connection methods for detachable connection, such as: plug connection, snap connection, Velcro bonding, adsorption connection, and threaded connection, etc., which can be set according to needs.
[0049] See Figure 2 、 Figure 4 and Figure 6 , the sound output portion 12 includes a convex shell protruding from the surface of the headphone body 1, and the connecting member 22 is provided with a concave hole 221 that matches the convex shell, and the connecting member 22 is sleeved outside the convex shell.
[0050] For the convenience of connection and to allow the sound to be smoothly introduced into the ear cap 21; in this technical solution, the convex shell and the concave hole 221 are used in cooperation. When the connecting member 22 is sleeved on the convex shell, a fit connection or an interference fit connection can be used to make the connection between the connecting member 22 and the convex shell relatively tight.
[0051] See Figure 3 and Figure 8 , the side surface of the convex shell is provided with an L-shaped card slot 13, and the inner side wall of the connecting member 22 is provided with a card block 222, and the card block 222 is snapped into one end of the L-shaped card slot 13.
[0052] The L-shaped card slot 13 includes an entrance section 131 and a clamping section 132. When cooperating with the clamping block 222, the connecting member 22 first gradually approaches the convex shell until the clamping block 222 abuts against the surface of the convex shell. Then, the connecting member 22 is gradually rotated and slightly pressed; until the clamping block 222 completely enters the entrance section 131. At this time, the rotation is stopped and the connecting member 22 is pressed. The connecting member 22 moves relative to the convex shell until the clamping block 222 enters the bottom of the entrance section 131; then the connecting member 22 is rotated again, and the clamping block 222 moves within the clamping section 132 until the clamping block 222 reaches one end of the clamping section 132 far from the entrance section 131. Thus, the clamping block 222 is snapped into one end of the L-shaped card slot 13, and the clamping block 222 cannot move perpendicular to the length direction of the clamping section 132, and the connecting member 22 cannot be separated from the convex shell.
[0053] To facilitate limiting the clamping block 222 in the clamping section 132; a limiting convex point 133 is provided on the side wall of one end of the clamping section 132 close to the entrance section 131.
[0054] When the clamping block 222 is snapped into the clamping section 132, it first abuts against the limiting convex point 133. Since one end of the clamping section 132 close to the entrance section 131 is in a suspended state and has a certain elasticity; the clamping block 222 pushes the limiting convex point 133 upwards, and the clamping section 132 undergoes elastic deformation until the clamping block 222 leaves the limiting convex point 133 and enters the clamping section 132; the clamping section 132 returns to its original state, and the limiting convex point 133 restricts the clamping block 222 within the clamping section 132; when disassembly is required, the connecting member 22 needs to be rotated forcefully, and the clamping block 222 pushes the limiting convex point 133 upwards again, and the end of the clamping section 132 deforms until the clamping block 222 leaves the limiting convex point 133 and enters the entrance section 131.
[0055] As other ways of detachable connection, the following structures can be adopted:
[0056] 1: The side surface of the convex shell is provided with an external thread, and the inner side surface of the inner concave hole 221 is provided with an internal thread, and the connecting member 22 is threadedly connected to the convex shell.
[0057] 2: The outer end of the connecting member 22 is provided with an outwardly turned edge, and the outwardly turned edge adheres to the surface of the earphone body 1; the outwardly turned edge is adhesively connected to the surface of the earphone body 1.
[0058] 3: The side surface of the connecting member 22 is connected with a positioning convex block, and the earphone body 1 is provided with a positioning concave hole that matches the positioning convex block. The positioning convex block is snapped into the positioning concave hole, and the positioning convex block is connected with the positioning concave hole by interference fit or mating connection.
[0059] In the specific setting of the second method, the outwardly turned edge can be made very thin, and the surface of the earphone body 1 is made relatively smooth. By squeezing the outwardly turned edge, the outwardly turned edge is adhesively connected to the earphone body 1.
[0060] See Figure 2 、Figure 3 , Figure 4 and Figure 8 , the sound output part 12 is provided with a main sound pickup hole 14, and the main sound pickup hole 14 faces the diaphragm of the speaker 16 or faces away from the diaphragm ( Figure 9 in the axial direction in
[0061] ). For better noise reduction, a main sound pickup hole 14 facing the diaphragm of the speaker 16 or facing away from the diaphragm is provided on the earphone housing 11, and a main noise reduction microphone cooperating with the main sound pickup hole 14 is provided; the main noise reduction microphone picks up the sound of the speaker 16 and the surrounding sounds, and then through comparison, an application software is used for active noise reduction; using a microphone to pick up sounds for comparison and noise reduction is the prior art and will not be elaborated here.
[0062] Secondly, when setting the main noise reduction microphone, the main noise reduction microphone can be set in the front cavity, between the speaker 16 and the sound output part 12.
[0063] Preferably, the main sound pickup hole 14 is located in the middle of the sound output part 12.
[0064] For better noise reduction, the main sound pickup hole 14 is set in the middle of the sound output part 12, which can well acquire the background sound and the sound of the speaker, and transmit the sound signal back to the control circuit board 110 and then perform noise reduction through the chip.
[0065] Preferably, the sound outlet hole 15 is located at the edge of the sound output part 12, and the sound output part 12 is connected with a dust-proof net 18 cooperating with the sound outlet hole 15.
[0066] The sound outlet hole 15 is set at the edge of the sound output part 12. When the earphone is in use, the sound outlet hole 15 is closer to the external auditory canal. At the same time, for dust prevention, the dust-proof net 18 is provided.
[0067] Among them, the earphone housing 11 is also provided with a plurality of auxiliary sound pickup holes 116, and a plurality of corresponding auxiliary noise reduction microphones 115 are arranged inside the earphone housing 11. The auxiliary noise reduction microphones 115 are electrically connected to the control circuit board 110.
[0068] In order to be able to actively reduce noise when used as an open earphone, a plurality of auxiliary noise reduction microphones are arranged inside the earphone housing 11; specifically designed to be 2 - 6. The auxiliary noise reduction microphones are connected to the internal control circuit board 110, and the control circuit board 110 performs noise reduction processing and sends the noise-reduced audio signal to the earphone.
[0069] The noise reduction microphone can be set on the back surface of the earphone housing 11, that is, the end face facing away from the sound output part 12; or it can be set on the side surface of the earphone housing 11.
[0070] Furthermore, a side sound outlet hole 113 is provided on the side of the earphone housing 11, and a mesh cover 114 is connected to the earphone housing 11 and is matched with the side sound outlet hole 113.
[0071] By providing the side sound outlet hole 113, when used as an open earphone, it can be mixed with external sounds, making the sound more natural. At the same time, it can also assist the secondary noise reduction microphone 115 to obtain the sound emitted by the speaker 16 for sound comparison and assist in noise reduction.
[0072] Secondly, the mesh cover 114 can be used to prevent dust, avoiding external dust from entering and polluting the speaker 16 and the control circuit board 110.
[0073] See Figure 8 、 Figure 9 ; For convenient use, the earphone housing 11 of this technical solution includes an upper housing 111 and a lower housing 112 that are fixedly connected, and an intermediate connector 19 for connecting to the ear hook 3 is connected to one side of the upper housing 111 and the lower housing 112.
[0074] See Figure 6 、 Figure 7 ; One end of the connecting member 22 is provided with a connecting cylinder 23 that is matched with the ear cap 21, and the ear cap 21 is sleeved on the connecting cylinder 23.
[0075] The ear cap 21 can be made of various flexible materials such as soft silicone, rubber, and memory foam. When connected to the connecting member 22, it can be an interference fit connection, a mating connection, etc.
[0076] The ear cap 21 is made of a flexible material and is closely combined with the ear canal of the ear, which can not only prevent external sounds from entering to form noise, but also assist in fixing the earphone.
[0077] Preferably, a circular clamping groove 231 is provided in the middle of the connecting cylinder 23, a hollow connecting column 211 is provided in the middle of the ear cap 21, a thickening ring 212 with an inner side thickening is provided at one end of the connecting column 211, the thickening ring 212 is sleeved on the clamping groove 231, and the end of the connecting cylinder 23 passes through the thickening ring 212 and extends into the inside of the connecting column 211.
[0078] By providing the inner thickening ring 212 and the clamping groove 231, when the connecting column 211 is sleeved on the connecting cylinder 23, a clamping connection is also formed at the same time. Secondly, the hollow connecting column 211 is also a sound guiding column. After the sound enters the connecting member 22, it is exported from the connecting cylinder 23, enters the connecting column 211, and then enters the ear through the connecting column 211.
[0079] The above are only preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for the purpose of explaining the principles of the present invention, and cannot be interpreted as limiting the scope of protection of the present invention in any way.
