Description

Technical Field

[0001] This utility model relates to the field of Bluetooth headset technology, and in particular to a clip-on Bluetooth headset and its charging case. Background Technology

[0002] Clip-on headphones are worn by clipping onto the user's ears, with the sound-emitting part corresponding to the user's ear canal. Clip-on headphones are convenient, lightweight, and comfortable to wear. They mainly consist of a connecting part and sound-emitting components and a power supply component connected to both ends of the connecting part. The sound outlet of the sound-emitting component is aligned with the user's ear canal, and sound waves are transmitted from the outlet into the ear canal. While clip-on headphones are compact, due to their structural limitations, the vibration direction of the speaker diaphragm is not directly opposite the sound outlet. This causes the sound waves generated by the diaphragm vibration to radiate inside the sound-emitting component's housing before being output from the outlet. The sound is reflected inside the housing before exiting, which can easily cause interference, affecting sound quality and reducing the user's listening experience. Utility Model Content

[0003] The purpose of this invention is to provide a clip-on Bluetooth headset and its charging case. By reflecting the sound through a reflective cone, the sound waves will not linger too long inside the shell and cause wave interference. The sound waves are then directed to the sound outlet and transmitted to the user's ear canal, thereby improving sound quality and enhancing the user's listening experience.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: an ear clip Bluetooth headset, including a core assembly, a sound output assembly, and an ear clip connecting the core assembly and the sound output assembly. The sound output assembly includes a speaker housing, a speaker, and a reflector cone. The speaker housing has a sound cavity, and the bottom side of the sound cavity has a sound outlet communicating with the sound cavity. The speaker and the reflector cone are assembled in the sound cavity. The conical surface of the reflector cone is opposite to the speaker, so that the sound waves generated by the speaker vibration are reflected by the reflector cone to the sound outlet for output.

[0005] This invention employs the aforementioned technical solution. The internal mechanism integrates a battery and control circuit, which is electrically connected to a speaker within the sound-producing assembly via wires, driving the speaker to vibrate and produce sound. When the speaker vibrates, most of the sound waves are reflected by the sound-reflecting cone to the sound outlet and output from there. This avoids excessive lingering of sound waves within the speaker housing's acoustic cavity, preventing interference and ensuring the quality of the output sound waves. Furthermore, the sound-reflecting cone is coaxial with the speaker, maximizing the uniform reflection of the sound waves generated by the speaker. The concentrated reflection of sound waves by the sound-reflecting cone avoids sound interference and ensures a uniform output from the sound outlet, resulting in high sound energy and improved listening quality and experience for the user.

[0006] The aforementioned clip-on Bluetooth earphone has a side protrusion on the inner wall of the sound cavity, and a mounting slot on the side wall of the reflector cone that matches the shape of the side protrusion. The reflector cone is assembled onto the side protrusion through the mounting slot. The reflector cone is detachably mounted on the side protrusion through the mounting slot, achieving a quick assembly effect and shaping the reflector cone so that its conical surface is aligned with the speaker.

[0007] The aforementioned clip-on Bluetooth earphones have a sound-conducting cavity inside the speaker housing and a sound-conducting module outside the speaker housing. The sound-conducting module and the sound outlet are located on opposite sides of the sound-reflecting cone. The sound-conducting module is used to conduct sound through the sound cavity, allowing the sound waves inside to diffuse in a timely manner. Sound waves reflected by the sound-reflecting cone in a direction away from the sound outlet are guided out through the sound-conducting module, preventing them from accumulating in the sound cavity and causing a muffled sound, thus improving the sound quality of the earphones.

[0008] The aforementioned clip-on Bluetooth earphones have notches on the sidewalls of the sound cavity and vents on the sidewalls of the speaker housing. The sound guiding module contains an input section, a connecting section, and an output section. These sections connect via notches and vents, forming a sound guiding channel between the sound cavity and the outside of the speaker housing. Some sound waves within the sound cavity can be guided through this channel and discharged promptly, further improving the sound quality.

[0009] The aforementioned clip-on Bluetooth earphones have a silicone pad on the side opposite the sound component and the main body component. The silicone pad fits snugly against the user's ear; its elasticity enhances wearing comfort.

[0010] The aforementioned clip-on Bluetooth earphones have a first magnet on the side opposite the speaker assembly and the mechanism assembly for mutual attraction. The magnet uses magnetic attraction to keep the speaker assembly and mechanism assembly firmly clipped onto the user's ear, ensuring a secure fit.

[0011] The aforementioned clip-on Bluetooth headset has a groove on the speaker housing, an annular cover plate in the groove, a silicone pad in the groove, and a first magnet in the annular cover plate.

[0012] The aforementioned clip-on Bluetooth earphone includes an ear clip comprising an elastic metal wire, rubber plugs at both ends of the elastic metal wire, and an elastic coating cast onto the elastic metal wire and rubber plugs. The sound component and the driving mechanism are respectively connected to both ends of the ear clip and are integrally formed with the elastic coating. The elastic metal wire is elastic; its opening allows the driving mechanism and sound component to better pass through the ear. The elastic metal wire then clamps the driving mechanism and sound component tightly against the user's ear. The integral molding of the sound component and driving mechanism with the elastic coating simplifies the manufacturing process and improves the efficiency of earphone production.

[0013] Another technical solution provided by this utility model is: a charging case, including a charging case body and the above-mentioned clip-on Bluetooth earphones, the charging case body is provided with an earphone slot adapted to the clip-on Bluetooth earphones, the clip-on Bluetooth earphones are housed in the earphone slots, and the charging case body is hinged with an opening and closing cover.

[0014] The aforementioned charging case has a second magnet on both the opening / closing lid and the charging case body for magnetic attraction. The second magnet is used to attract the opening / closing lid, keeping it covering the charging case body.

[0015] The beneficial effects achieved by this utility model are as follows: A reflective cone is set inside the sound-emitting component to reflect the sound waves generated by the speaker vibration to the sound outlet, ensuring that most of the sound waves can be output from the sound outlet in a timely and accurate manner. This avoids excessive lingering of sound waves within the housing, which could lead to interference and improve sound quality. Furthermore, a sound-guiding module is set on the other side of the reflective cone, opposite the sound outlet. This module, consisting of an input section, a connecting section, an output section, a connecting notch, and a sound vent, forms a sound-guiding channel between the sound cavity and the outside of the speaker housing. This promptly guides the sound waves reflected from the reflective cone to this side, preventing sound waves from accumulating within the sound cavity and causing interference. Silicone pads and magnets are placed on the inner sides of the sound-emitting component and the mechanism component, allowing the headphones to clamp snugly to the ears and be cushioned by the silicone pads, improving the secure fit and comfort of the earphone.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] Reference Figures 1 to 7 As shown, a clip-on Bluetooth headset includes a core assembly 1, a sound-generating assembly 2, and an ear clip 3 connecting the core assembly 1 and the sound-generating assembly 2. The sound-generating assembly 2 includes a speaker housing 21, a speaker 22, and a reflector cone 23. The speaker housing 21 has a sound cavity 20 inside, and the bottom side of the sound cavity 20 has a sound outlet 24 communicating with the sound cavity 20. The speaker 22 and the reflector cone 23 are assembled in the sound cavity 20. The conical surface of the reflector cone 23 is opposite to the speaker 22, so that the sound waves generated by the vibration of the speaker 22 are reflected by the reflector cone 23 to the sound outlet 24 for output.

[0030] like Figure 2As shown, the bottom of the reflector cone 23 is mounted on the inner wall of the speaker housing 21, and its conical surface corresponds to the speaker 22. When the speaker 22 is powered and vibrates to produce sound, the generated sound waves are transmitted to the surface of the reflector cone 23. Through the reflection of the conical surface, most of the sound waves are reflected and output in the direction of the sound outlet 24. In this embodiment, the reflector cone 23 is set to be coaxially opposite to the speaker 22. In other embodiments, the setting position of the reflector cone 23 can be selected according to different needs. In order to prevent dust from entering the sound cavity 20, a dustproof mesh 26 is provided at the sound outlet 24.

[0031] like Figure 4 and Figure 5 As shown, in this embodiment, the inner wall of the sound cavity 20 is provided with a side protrusion 201, and the side wall of the reflecting cone 23 is provided with a mounting groove 231 that matches the shape of the side protrusion 201. The reflecting cone 23 is assembled onto the side protrusion 201 through the mounting groove 231. Specifically, the bottom surface of the reflecting cone 23 is provided with the mounting groove 231, and the reflecting cone 23 is hung on the side protrusion 201 on the inner wall of the sound cavity 20 through the mounting groove 231, thus completing the assembly of the reflecting cone 23.

[0032] Continue to refer to Figure 2 As shown, the speaker housing 21 has a sound-conducting cavity 20 inside and a sound-conducting module 25 outside the speaker housing 21. The sound-conducting module 25 and the sound outlet 24 are located on opposite sides of the reflecting cone 23. In some embodiments, the sound-conducting module 25 can be a conduit connecting the sound-conducting cavity 20 and the outside of the speaker housing 21 to guide some of the sound waves in the sound cavity 20 out, preventing them from staying in the sound cavity 20 and causing interference or resonance.

[0033] like Figure 6 As shown, in this embodiment, the side wall of the acoustic cavity 20 is provided with a notch 202, the side wall of the speaker housing 21 is provided with a sound vent 211, and the sound guiding module 25 is provided with an input section 251, a connecting section 252, and an output section 253. The input section 251, the connecting section 252, and the output section 253 connect the notch 202 and the sound vent 211, forming a sound guiding channel 25a that connects the acoustic cavity 20 and the outside of the speaker housing 21. Figure 2As shown, the sound guide module 25 is disposed on one side of the sound cavity 20. The sound guide module 25 and the sound outlet 24 are located on both sides of the reflecting cone 23, preferably radially. When the sound waves generated by the speaker 22 are transmitted in the sound cavity 20, some sound waves that are not output from the sound outlet 24 remain in the sound cavity 20. To avoid excessive retention of these sound waves in the sound cavity 20, which would cause the sound quality to become muffled, the sound guide module 25 is provided. Excess sound waves in the sound cavity 20 enter the sound guide module 25 through the notch 202, pass through the input section 251 in the opposite direction, then pass through the connecting section 252 in a direction perpendicular to the input section 251, and then pass through the output section 253 in the opposite direction to the input section 251, finally exiting from the vent 211 outside the speaker housing 21. By exporting the excess sound waves inside the speaker housing 21, the muffled sound is changed and the sound quality of the headphones is improved.

[0034] Reference Figure 2 and Figure 3 As shown, in this embodiment, a silicone pad 4 is provided on the side of the sound-emitting component 2 opposite to the mechanism component 1. The silicone pad 4 is elastic, improving wearing comfort when clipped onto the user's ear. A first magnet 5 for mutual attraction is provided on the side of the sound-emitting component 2 opposite to the mechanism component 1. The first magnet 5 is provided on the side of the sound-emitting component 2 opposite to the mechanism component 1, and the surfaces of the corresponding magnets maintain opposite polarities. Through the attraction of the magnets, the clamping force of the earphones on the ear is increased, allowing the earphones to be more securely clipped onto the user's ear, ensuring that the earphones remain clamped on the ear and do not fall off during activities such as running.

[0035] In this embodiment, the speaker housing 21 has a groove 212, and an annular cover plate 213 is provided in the groove 212. The silicone pad 4 is disposed in the groove 212, and a first magnet 5 is disposed in the annular cover plate 213. By providing the groove 212, the silicone pad 4 is disposed in the groove 212, which prevents the silicone pad 4 from protruding excessively from the speaker housing 21. Furthermore, the first magnet 5 is disposed in the groove 212, so that the first magnet 5 will not press against the silicone pad 4, resulting in high comfort when the earphone is clipped on the ear.

[0036] like Figure 7As shown, the ear clip 3 includes an elastic metal wire 31, rubber plugs 32 at both ends of the elastic metal wire 31, and an elastic coating 33 cast onto the elastic metal wire 31 and rubber plugs 32. The sound component 2 and the core component 1 are respectively connected to both ends of the ear clip 3 and are integrally formed with the elastic coating 33. A wire 34 passes through the ear clip 3, with both ends extending into the core component 1 and the speaker component 2, connecting the core component 1 and the speaker component 2. The ear clip 3 can be cast by simultaneously placing the elastic metal wire 31 and the wire 34 into a mold. Rubber plugs 32 are first cast into both ends of the elastic metal wire 31 to form an integral shape. Then, the core component 1 and the speaker component 2 are placed into both ends of the elastic metal wire 31, with both ends of the wire 34 passing through the core component 1 and the speaker component 2, respectively. Finally, the elastic coating 33 is cast, so that the core housing 11 of the core component 1 and the speaker housing 21 of the speaker component 2 are integrally formed with the elastic coating 33.

[0037] like Figure 1 , Figure 3 , Figure 4 As shown, the mechanism assembly 1 includes a mechanism housing 11, a control circuit board 12 disposed inside the mechanism housing 11, a battery 13, a battery bracket 14, a touch pin 15, a touch pad 16, and a charging contact 17. The battery 13 is mounted on the battery bracket 14, and the control circuit board 12 is located on the other side of the battery bracket 14. The touch pin 15 is located on the control circuit board 12, and the touch pad 16 is located at the outer end of the touch pin 15 to expand the touch area and facilitate user touch control. The charging contact 17 is located at the bottom of the mechanism housing 11 and is used to contact the charging structure for charging. The two ends of the wire 34 pass through the mechanism housing 11 and the speaker housing 21, respectively, and are connected to the control circuit board 12 and the speaker 22, respectively, to realize the electrical connection between the speaker 22 and the control circuit board 12.

[0038] Reference Figures 8 to 11 As shown, a charging case includes a charging case body 61 and a clip-on Bluetooth earphone 1a as described in the above specific embodiment. The charging case body 61 is provided with an earphone slot 62 adapted to the clip-on Bluetooth earphone 1a, and the clip-on Bluetooth earphone 1a is housed in the earphone slot 62. A hinged cover 63 is hinged to the charging case body 61. The hinged cover 63 is rotatably mounted on the charging case body 61 via a pivot 631. A torsion spring 632 is also provided between the charging case body 61 and the hinged cover 63. The elastic force provided by the torsion spring 632 ensures that the hinged cover 63 remains tightly closed when it is closed on the charging case body 61.

[0039] like Figure 10 As shown, the hinged cover 63 and the charging case 61 are respectively provided with a second magnet 64 for magnetic attraction. The second magnet 64 is used to attract the hinged cover 63, so that the hinged cover 63 remains closed when it is placed on the charging case 61, protecting the earphones from slipping out of the earphone slot 62.

[0040] like Figure 10 , Figure 11 As shown, the charging case 61 contains a charging circuit board 65, a charging pin 66, a USB interface 67, and a rechargeable battery 68. The charging pin 66 is located on the charging circuit board 65, and its tip extends into the earphone slot 62. When the ear-clip Bluetooth earphone 1a is placed in the earphone slot 62, the charging pin 66 contacts and abuts against the charging contact 17 of the earphone 1a. The USB interface 67 is connected to the charging circuit board 65 and is used to connect an external power source to charge the rechargeable battery 68.

[0041] In this embodiment, the charging case 61 includes a base 611 and a silicone shell 612. The silicone shell 612 is fitted onto the base 611. The space formed between the inner wall of the silicone shell 612 and the bottom of the base 611 is used to install the charging circuit board 65, the charging battery 68, and the charging pins 66. A button 69 is provided on the side wall of the base 611 to activate the charging circuit board 65. The button 69 protrudes from the silicone shell 612. A third magnet 613 is provided on the charging circuit board 65. When the earphone 1a is placed into the earphone slot 62, the third magnet 613 firmly attracts the earphone 1a, keeping the charging pins 66 in close contact with the charging contacts 17.

[0042] In a specific implementation, the ear-clip Bluetooth earphone of this utility model is worn on the user's ear. The ear clip 3 provides clamping force, clamping the speaker assembly 2 and the core assembly 1 onto the user's ear, with the speaker assembly 2 aligned with the user's ear canal. Because the inner sides of the speaker housing 21 and the core housing 11 are provided with silicone pads 4 and a first magnet 5, the clamping force is improved, and the cushioning effect of the silicone pads 4 enhances the comfort of wearing the earphone.

[0043] Touching the touch area on the housing 11 activates the headphones. The control circuit board 12 is electrically connected to the speaker 22 via wire 34 and drives the speaker 22 to vibrate and produce sound, allowing the wearer to hear the sound. The battery 13 provides the power required for the control circuit board 12 and the speaker 22 to vibrate.

[0044] After the speaker 22 is powered on and produces sound, sound waves are transmitted inside the sound cavity 20. Part of the sound waves are output directly from the sound outlet 24, and part of the sound waves are output from the sound outlet 24 after being reflected by the reflecting cone 23. The remaining sound waves that do not exit from the sound outlet 24 and remain in the sound cavity 20 are guided by the sound guiding module 25 and exported through the sound guiding channel 25a. This avoids destructive interference caused by too many sound waves remaining in the sound cavity 20, which would affect the sound quality.

[0045] When the earphones are not in use or need charging, place them in the earphone slot 62 of the charging case. The earphones are then attracted by the third magnet 613. The charging pin 66 is in close contact with the charging contact 17. The rechargeable battery 68 inside the charging case 61 provides power to the charging circuit board 65 and to the Bluetooth earphones 1a. During charging, the charging pin 66 connects to the charging contact 17, and the electrical energy stored in the rechargeable battery 68 connects to the control circuit board 12 and the battery 13 of the Bluetooth earphones through the charging contact 17, thus charging the earphones' battery.

[0046] The opening and closing cover 63 is closed onto the charging case 61 by the action of the pivot 631 and the torsion spring 632, and is kept closed onto the charging case 61 by the magnetic attraction of the second magnet 64, protecting the earphones from slipping out of the earphone slot 62.

[0047] In summary, this utility model has been manufactured into actual samples as described in the specification and figures, and has undergone multiple use tests. The results of these tests demonstrate that this utility model can achieve its intended purpose, and its practical value is undeniable. The embodiments described above are merely illustrative examples of this utility model and are not intended to limit it in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in this utility model without departing from its technical features shall also fall within the scope of this utility model's technical features.
