Description

Technical Field

[0001] This utility model belongs to the field of sound transmission devices, specifically relating to an integrated air duct earphone. Background Technology

[0002] In daily life, headphones are frequently used as a sound transmitter in electronic devices such as mobile phones, music players, and computers. Headphones, as common electronic products, are divided into wired and wireless headphones. Whether wired or wireless, the speakers in existing headphones are located inside the earbuds, and sound is emitted from the speakers and enters the ear. Prolonged wear can cause discomfort due to the magnetic radiation generated by the speakers. Furthermore, the connection points at both ends of the headphone cable are prone to bending, tangling, or knotting, which can cause the internal copper wires to break, leading to headphone damage and shortening its lifespan. Utility Model Content

[0003] The purpose of this invention is to provide an integrated air duct earphone to solve the problem of short earphone lifespan.

[0004] The integrated air duct earphone of this utility model is implemented as follows:

[0005] An integrated air duct earphone includes a speaker, an earpiece, and at least one air duct. The speaker is connected to an electronic device and has a speaker installed inside. One end of the air duct is detachably connected to the speaker, and the other end is detachably connected to the earpiece.

[0006] Furthermore, the air duct is provided with one or two.

[0007] Furthermore, the air duct includes a flexible hollow duct body and a braided sleeve fitted over the hollow duct body.

[0008] Furthermore, the braided sleeve and the hollow conduit body are designed separately;

[0009] The two ends of the braided sleeve are fixed to the outer wall of the hollow conduit body with glue.

[0010] Furthermore, the end of the hollow conduit body extends from or is flush with the end of the braided sleeve.

[0011] Furthermore, the sound generator is provided with a first conduit connection hole that communicates with the cavity where the speaker is located, and one end of the air conduit is installed in the first conduit connection hole.

[0012] Furthermore, the earplug is provided with a second conduit connection hole, and one end of the air conduit is fitted into the second conduit connection hole.

[0013] Furthermore, detachable metal tubes are installed at both ends of the air duct;

[0014] A dustproof net is installed inside the end of the metal tube away from the air duct.

[0015] Furthermore, the sound generator is equipped with a connector.

[0016] Furthermore, the sound generator is connected to a connector via a wire.

[0017] After adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0018] This invention utilizes an air duct to transmit sound, which not only keeps the speaker away from the user's head, reducing the adverse effects of electromagnetic radiation, but also prevents the copper wires inside the headphone cable from breaking due to bending, thus reducing the likelihood of headphone failure and extending its lifespan. If any end of the air duct breaks during use, the damaged part can be cut off, and the remaining part can still be used, thereby reducing operating costs and minimizing resource waste.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0035] Example 1

[0036] like Figure 1-6As shown, an integrated air duct earphone includes a speaker 1, an earplug 2 and at least one air duct 3. The speaker 1 is connected to an electronic device and has a speaker 4 installed inside it. One end of the air duct 3 is detachably connected to the speaker 1 and the other end is detachably connected to the earplug 2.

[0037] In this embodiment, an air duct 3 is provided.

[0038] One end of the air duct 3 is connected to the speaker 1, and the other end is connected to the earplug 2. The sound emitted by the speaker 4 is transmitted to the ear through the air duct 3 and the earplug 2 so that it can be received by the user.

[0039] To reduce the chance of damage to the air duct 3, the air duct 3 includes a flexible hollow duct body 3-1 and a braided sleeve 3-2 that is fitted over the hollow duct body 3-1.

[0040] The braided sleeve 3-2 is used to protect the hollow conduit body 3-1. It is wrapped around the outside of the hollow conduit body 3-1 and can effectively reduce the wear and tear on the hollow conduit body 3-1 during use.

[0041] Using the braided sleeve 3-2 as a protective sleeve for the hollow duct body 3-1 not only improves the comfort of using the air duct 3, but also has good wear resistance and better protection.

[0042] The hollow conduit body 3-1 can be made of, but is not limited to, PE or silicone material.

[0043] The braided sleeve 3-2 and the hollow conduit body 3-1 are designed separately.

[0044] The braided sleeve 3-2 and the hollow conduit body 3-1 are designed to be separate. When the braided sleeve 3-2 is severely worn, it can be replaced, so that the internal hollow conduit body 3-1 can be reused, reducing resource waste and lowering the cost of use.

[0045] To prevent the braided sleeve 3-2 from moving around freely outside the hollow conduit body 3-1 during use, both ends of the braided sleeve 3-2 are fixed to the outer wall of the hollow conduit body 3-1 with glue 5.

[0046] Preferably, quick-drying adhesive can be used for adhesive 5.

[0047] The braided sleeve 3-2 and the hollow conduit body 3-1 are not limited to a separate design. The braided sleeve 3-2 can be completely fixed to the outer wall of the hollow conduit body 3-1 using glue 5, so that the two form a whole. This can better fix the braided sleeve 3-2.

[0048] To facilitate the connection of the hollow tube body 3-1 to the earplug 2 and the sound generator 1, the end of the hollow tube body 3-1 extends from the end of the braided sleeve 3-2.

[0049] In order to transmit the sound in the speaker 1 to the earplug 2 through the air duct 3, the speaker 1 is provided with a first duct connection hole 6 that communicates with the cavity where the speaker 4 is located, and one end of the air duct 3 is installed in the first duct connection hole 6.

[0050] In this embodiment, the sound generator 1 includes a housing, a speaker 4 is disposed inside the housing, a first conduit connection hole 6 is disposed on the housing, and one end of the hollow conduit body 3-1 is fitted into the first conduit connection hole 6.

[0051] In this embodiment, in order to ensure the firm connection between the hollow duct body 3-1 and the sound generator 1, a neck is provided at the end of the sound generator 1 connected to the air duct 3, and a first heat shrink sleeve 7 is fitted on the neck. At the same time, the first heat shrink sleeve 7 is fitted on the outside of the air duct 3. In this way, the first heat shrink sleeve 7 can be used to ensure the firm connection between the sound generator 1 and the air duct 3.

[0052] In order to transmit sound into the earplug 2, the earplug 2 is provided with a second conduit connection hole 8, and one end of the air conduit 3 is fitted into the second conduit connection hole 8.

[0053] In this embodiment, the end of the earplug 2 connected to the air duct 3 is provided with a necked section, and a second heat-shrink sleeve 9 is fitted on the necked section. At the same time, the second heat-shrink sleeve 9 is fitted on the outside of the air duct 3, which can be used to ensure the firmness of the connection between the earplug 2 and the air duct 3.

[0054] Preferably, the end of the air duct 3 body is hardened with hardening glue, which makes it easy to assemble with the speaker 1 and the earplug 2.

[0055] This embodiment discloses four shapes of earplug 2, but the shape of earplug 2 is not limited to these.

[0056] To facilitate connection to electronic devices, the speaker 1 is equipped with a connector 10.

[0057] In this embodiment, the connector 10 is directly disposed on the housing of the speaker 1 and is electrically connected to the speaker 4, thereby transmitting the electrical signal of the electronic device to the speaker 4 and converting it into a sound signal using the speaker 4, which is then transmitted to the earplug 2 and into the ear via the air duct 3.

[0058] When any end of the air duct 3 is damaged, taking the end connected to the sound generator 1 as an example, first cut open the first heat shrink tubing 7 outside the sound generator 1, then pull the air duct 3 out of the first duct connection hole 6. At this time, the damaged part of the air duct 3 can be cut off, and one end of the hollow duct body 3-1 at this end can be extended from the braided sleeve 3-2. The end of the braided sleeve 3-2 can be fixed to the outer wall of the hollow duct body 3-1 with glue 5. Then, the end of the hollow duct body 3-1 can be hardened with hardening glue 5. After the treatment is completed, the end of the hollow duct body 3-1 can be assembled into the first duct connection hole 6, and then fixed with a new first heat shrink tubing 7.

[0059] This invention uses an air duct 3 for sound transmission. When any end of the air duct 3 is damaged, the damaged part can be cut off, and the remaining part can be reassembled with the corresponding parts. The headphones can then be used normally. The whole process is convenient and can effectively improve the service life of the headphones and reduce resource waste.

[0060] Example 2

[0061] like Figure 7 As shown, based on Embodiment 1, this embodiment also provides an integrated air duct earphone, whose structure is roughly the same as that of Embodiment 1, except that...

[0062] The first conduit connection hole 6 is a slit structure, that is, a silicone plug 11 is provided at the end where the sound generator 1 is connected to the air conduit 3, and the first conduit connection hole 6 is set on the silicone plug 11. When the air conduit 3 is not installed in the first conduit connection hole 6, the first conduit connection hole 6 is slit-shaped, which can prevent dust from entering the interior of the sound generator 1. When connecting, the end of the air conduit 3 can be directly inserted into the first conduit connection hole 6.

[0063] In this connection method, the sound generator 1 does not need to be fitted with a neck, and therefore the first heat shrink tubing 7 does not need to be installed. Since the silicone plug 11 is made of a flexible material, it has a certain degree of elasticity, which can ensure the stability of the connection between the two after the air duct 3 is assembled.

[0064] Example 3

[0065] like Figure 8 As shown, based on Embodiment 1, this embodiment also provides an integrated air duct earphone, whose structure is roughly the same as that of Embodiment 1, except that...

[0066] There are two air ducts 3.

[0067] Correspondingly, the outer shell of the speaker 1 is provided with two first conduit connection holes 6. The same side ends of the two air conduits 3 are respectively fitted into the two first conduit connection holes 6, while the other end is fitted with an earplug 2, so that both ears can use the headphones at the same time.

[0068] In this embodiment, the two air ducts 3 can be fixed using the same first heat shrink tubing 7.

[0069] Example 4

[0070] like Figure 9 As shown, based on Embodiment 1, this embodiment also provides an integrated air duct earphone, whose structure is roughly the same as that of Embodiment 1, except that...

[0071] The end of the hollow conduit body 3-1 is flush with the end of the braided sleeve 3-2.

[0072] After the end of the braided sleeve 3-2 is fixed to the hollow conduit body 3-1 using glue 5, the ends on the same side of the two can be assembled as a whole into the first conduit connection hole 6 or the second conduit connection hole 8.

[0073] Example 5

[0074] like Figure 10-11 As shown, based on Embodiment 1, this embodiment also provides an integrated air duct earphone, whose structure is roughly the same as that of Embodiment 1, except that...

[0075] The air duct 3 is fitted with detachable metal tubes 12 at both ends.

[0076] In this embodiment, the end of the hollow conduit body 3-1 does not need to be treated with hardening glue, and a metal tube 12 can be installed separately to facilitate connection with the earplug 2 and the sound generator 1.

[0077] The metal tube 12 and the hollow conduit body 3-1 can be connected in the following three ways:

[0078] The first method is to match the outer diameter of the metal tube 12 with the inner diameter of the hollow conduit body 3-1. The metal tube 12 can be directly inserted into the end of the hollow conduit body 3-1 to achieve the connection between the two. This connection method allows for easy disassembly of the metal tube 12.

[0079] The second method involves a third heat-shrinkable sleeve 14 at the connection between the metal tube 12 and the hollow conduit body 3-1. After the metal tube 12 is inserted into the hollow conduit body 3-1, the third heat-shrinkable sleeve 14 can be used to fix the connection between the two. This connection method can ensure the firmness of the connection between the metal tube 12 and the hollow conduit body 3-1. This embodiment adopts this connection method.

[0080] The third option is to use a metal tube 12 with an outer diameter slightly larger than the inner diameter of the hollow conduit body 3-1, since the hollow conduit body 3-1 is a flexible tube with a certain degree of elasticity. In this way, after the metal tube 12 is connected to the hollow conduit body 3-1, the elasticity of the tube wall of the hollow conduit body 3-1 can increase the stability of the connection between it and the metal tube 12.

[0081] To prevent dust from entering the hollow duct body 3-1 and affecting the sound transmission effect, a dustproof net 13 is installed inside the end of the metal tube 12 away from the air duct 3.

[0082] The dustproof net 13 can be directly welded into the metal pipe 12, or it can be installed in the metal pipe 12 in a detachable manner, making it convenient to disassemble and clean the dustproof net 13.

[0083] In this embodiment, if any end of the air duct 3 is damaged, the metal tube 12 can be removed from the hollow duct body 3-1 before cutting. After cutting, the metal tube 12 is then assembled back onto the hollow duct body 3-1 and fixed with the third heat shrink tubing 14. Then it can be connected to the earplug 2 or the speaker 1.

[0084] Example 6

[0085] like Figure 12 As shown, based on Embodiment 1, this embodiment also provides an integrated air duct earphone, whose structure is roughly the same as that of Embodiment 1, except that...

[0086] The sound generator 1 is connected to the connector 10 via a wire 15.

[0087] In this embodiment, the speaker 1 and the connector 10 are connected by a wire 15. That is, the wire 15 connects the connector 10 and the speaker 4 inside the speaker 1. After the connector 10 is connected to the electronic device, the electrical signal is transmitted to the speaker 1 through the connector 10 and the wire 15. The speaker 4 converts the electrical signal into a sound signal, which is then transmitted through the air duct 3 and the earplug 2.
