Description

Technical Field

[0001] This utility model relates to the field of headphone technology, and in particular to a waterproof button structure for headphones and a bone conduction headphone. Background Technology

[0002] Bone conduction headphones convert sound into vibrations of different frequencies, which are then transmitted through the human body. With the increasing popularity of bone conduction headphones, people are increasingly enjoying using them, for example, while running, exercising, or even diving. This places higher demands on the waterproofing performance of bone conduction headphones. Currently, bone conduction headphones typically use sealant or additional sealing components to achieve a waterproof seal in the button area, but this often fails to meet the desired waterproofing requirements. Gaps exist between the button area and the shell, resulting in inadequate sealing and making it difficult to achieve a high level of waterproofing. Utility Model Content

[0003] The purpose of this utility model is to provide a waterproof button structure for headphones and a bone conduction headphone. The button part is integrally formed with the core housing in a secondary process, which reduces assembly steps, ensures waterproof sealing between the button part and the core housing, and improves the waterproof level of the headphone product.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a waterproof button structure for headphones, including a core housing and a button part. The core housing is integrally formed and has a button groove. A button hole is provided in the middle of the button groove. The button part includes a button body, which is disposed in the button groove and integrally formed with the core housing by secondary injection molding. A button protrusion extends from the inner side of the button body and extends into the interior of the core housing.

[0005] This utility model adopts the above-mentioned technical solution. After the mechanism housing is integrally injection molded, the button body and the mechanism housing are then integrally molded, so that the button body and the mechanism housing are injection molded as one piece. The button body can fit tightly into the button groove, ensuring the sealing and waterproofing of the button part and the mechanism housing. The use of a secondary molding process simplifies the process of assembling the button part onto the mechanism housing and improves production efficiency. The button body extends into the interior of the mechanism housing through an extended button protrusion for pressing the internal switch button to realize the press control function.

[0006] The waterproof button structure of the aforementioned headphones features a sealing ring extending from the periphery of the button body corresponding to the button protrusion. The outer wall of the sealing ring tightly fits against the wall of the button hole. This sealing ring seals each button hole, enhancing the waterproof effect.

[0007] The aforementioned waterproof button structure of the headphones features a button body surface flush with the inner casing surface, and button protrusions extending from the outer side of the button body corresponding to the button pillars. These button protrusions allow users to directly press the corresponding buttons. The flush surface of the button body with the inner casing prevents uneven steps after injection molding, thus improving the sealing and waterproofing effect.

[0008] The aforementioned waterproof button structure of the headphones features buttons made of silicone material, with the button protrusion, sealing ring, and button bump integrally molded with the button body. This integrated molding of the silicone button protrusion, sealing ring, and button bump provides elasticity, ease of pressing, and excellent waterproof performance.

[0009] This utility model also provides another technical solution: a bone conduction headphone, including the waterproof button structure of the headphone described above.

[0010] The aforementioned bone conduction headphones include a rear-hook assembly and ear hook assemblies connected to both ends of the rear-hook assembly. Each ear hook assembly includes a headphone mechanism, ear hooks, and a sound-generating module. The headphone mechanism and the sound-generating module are connected via the ear hooks. The ear hooks are used to hang the headphones on the user's ears. The headphone mechanism drives the sound-generating module to vibrate. When the headphone module vibrates against the user's skin, it transmits sound to the body through mechanical vibration, allowing the user to hear the sound.

[0011] The aforementioned bone conduction headphones include a headphone mechanism comprising a mechanism housing and a side cover mounted on the side of the mechanism housing. Inside the mechanism housing are a circuit board and a switch button. The switch button is located on the circuit board, with the inner end of a button protrusion corresponding to the switch button. Pressing the button protrusion causes the button protrusion to move inward, pressing the switch button and activating its function.

[0012] The aforementioned bone conduction headphones include an ear hook body and a silicone cover. The ear hook body has a cable channel connecting the sound module and the core housing, and the silicone cover covers the cable channel. During assembly, the vibrator inside the sound module is connected to the circuit board inside the core housing via wires. The wires pass through the cable channel for easy wiring. After wiring is completed, the silicone cover is placed over the cable channel. The connection can be achieved through injection molding or sealing with glue, facilitating wiring between the sound module and the circuit board. The silicone cover also provides good waterproofing.

[0013] The aforementioned bone conduction headphones have a battery housed within the core housing. The battery is connected to a circuit board via wires. The circuit board has a charging pin and a magnetic magnet. The magnetic magnet is used to hold the charging device in place, ensuring a tight contact between the charging pin and the charging connector of the device, thus charging the battery. The battery provides power for the headphones to operate normally.

[0014] The aforementioned bone conduction headphones include a speaker base and a speaker cover as the sound-generating module. The speaker cover is sealed to the speaker base, and a vibrator is located inside the speaker base. The mechanism housing, ear hook body, and speaker base are integrally molded. This integral molding of the mechanism housing, ear hook body, and speaker base forms a single unit, which helps to ensure the overall sealing of the headphone product. Furthermore, this integral molding allows for rapid production and improves production efficiency.

[0015] The beneficial effects of this utility model are: the button part is integrally formed with the mechanism housing by a secondary molding process, which simplifies the processing steps and ensures the sealing and waterproof performance of the button and the mechanism housing.
