Abstract
Description
Technical Field
[0001] This invention relates to the field of Bluetooth headset technology, and more particularly to a headset case and headset. Background Technology
[0002] With the rapid development of technology, Bluetooth headsets are becoming increasingly popular, widely used in daily life due to their advantages such as wireless transmission and portability. Bluetooth headsets typically consist of the earbuds themselves and a charging case. The charging case serves to store and charge the earbuds, ensuring their proper functioning.
[0003] Existing Bluetooth earphone cases contain conductive springs, while the earphones themselves have conductive contacts. When the earphones are placed in the case, the conductive contacts make contact with the conductive springs, thus charging the earphones. However, to better fit the contours of the human ear and improve wearing comfort, the earphones are typically designed with an irregular curved surface that conforms to the ear. In this case, the conductive springs cannot effectively and stably make contact with the conductive contacts for charging.
[0004] Therefore, there is an urgent need to design an earphone case to solve the aforementioned problems in the existing technology. Summary of the Invention
[0005] The purpose of this embodiment is to provide an earphone case and earphones, which have a contoured contact pin structure adapted to the irregular curved surface of the earphone body, so as to meet the charging needs of the complex-shaped earphone body.
[0006] To achieve this objective, the following technical solution is adopted in this embodiment:
[0007] The headphone case includes:
[0008] The box body is equipped with a charging slot;
[0009] A charging board assembly includes a positive contact pin and a negative contact pin, both of which are disposed in the charging slot, and the axes of the positive contact pin and the negative contact pin are located in different planes.
[0010] When the earphone body is placed in the charging slot, the positive contact pin is configured to abut against the positive contact point of the earphone body, and the negative contact pin is configured to abut against the negative contact point of the earphone body.
[0011] Preferably, the earphone case further includes a cover, which is connected to the case body and can cover the charging slot.
[0012] Preferably, one of the cover and the other of the box is provided with a first magnetic attractor and a magnet, and the first magnetic attractor is attracted to the magnet.
[0013] Preferably, the positive electrode contact pin is retractably disposed in the charging slot and / or the negative electrode contact pin is retractably disposed in the charging slot.
[0014] Preferably, the cross-section at the positive contact on the outer wall of the earphone body is a first tangent plane, and when the positive contact pin abuts against the positive contact, its axis is perpendicular to the first tangent plane; and / or, the cross-section at the negative contact on the outer wall of the earphone body is a second tangent plane, and when the negative contact pin abuts against the negative contact, its axis is perpendicular to the second tangent plane.
[0015] Preferably, the projection of the axis of the positive electrode contact pin onto the XY plane is the first positive electrode projection line, and the projection of the axis of the negative electrode contact pin onto the XY plane is the first negative electrode projection line.
[0016] The angle between the first positive projection line and the X-axis is 90°-135°, and the angle between the first negative projection line and the X-axis is 45°-60°.
[0017] Preferably, the projection of the axis of the positive electrode contact pin onto the YZ plane is the second positive electrode projection line, and the projection of the axis of the negative electrode contact pin onto the YZ plane is the second negative electrode projection line.
[0018] The angle between the second positive projection line and the Y-axis is 10°-20°, and the angle between the second negative projection line and the Y-axis is 20°-45°.
[0019] Preferably, the projection of the axis of the positive electrode contact pin onto the XZ plane is the third positive electrode projection line, and the projection of the axis of the negative electrode contact pin onto the XZ plane is the third negative electrode projection line.
[0020] The angle between the third positive projection line and the Z-axis is 3°-10°, and the angle between the third negative projection line and the Z-axis is 20°-45°.
[0021] The earphones include an earphone body and the aforementioned earphone case, wherein the earphone body is placed in the charging slot of the case.
[0022] Preferably, the charging slot is provided with a second magnetic element, which is attached to the earphone body.
[0023] The beneficial effects of this embodiment are as follows:
[0024] The earphone case provided in this embodiment includes a case body and a charging board assembly. Since the case body has a charging slot, the earphone body can be placed in the charging slot, thus the earphone case can store the earphone body and prevent it from being lost. The charging board assembly includes a positive contact pin and a negative contact pin. Since the positive contact pin and the negative contact pin abut against the positive and negative contacts of the earphone body respectively when the earphone body is placed in the charging slot, the earphone case can realize the normal charging function of the earphone body to ensure the daily use of the earphone body. Since the axis of the positive contact pin and the axis of the negative contact pin are located in different planes, that is, they are set on opposite planes, the flexibility and adaptability of the charging board assembly are greatly improved. This allows the earphone case to form a contoured contact pin structure that adapts to the earphone body, so as to fit the complex and irregular surface of the earphone body, thereby maintaining effective contact with the contacts on the earphone body and meeting the charging performance requirements of the complex-shaped earphone body.
[0025] The earphones provided in this embodiment include an earphone body and the aforementioned earphone case. The earphone body is placed in the charging slot of the case, thus the earphones can serve to store and protect the earphone body. The positive contact pin and the axis of the earphone are arranged opposite to the axis of the negative contact pin, rather than being simply parallel or symmetrical. Therefore, a contoured structure adapted to the earphone body is formed to meet the charging requirements of irregularly shaped earphone bodies. Attached Figure Description

[0038] like Figures 1 to 4As shown, this embodiment provides an earphone case, which includes a case body 1 and a charging board assembly 2. The case body 1 is provided with a charging slot 11. The charging board assembly 2 includes a positive contact pin 211 and a negative contact pin 221. Both the positive contact pin 211 and the negative contact pin 221 are disposed in the charging slot 11, and the axis of the positive contact pin 211 and the axis of the negative contact pin 221 are located in different planes. When the earphone body 100 is placed in the charging slot 11, the positive contact pin 211 is configured to abut against the positive contact point 110 of the earphone body 100, and the negative contact pin 221 is configured to abut against the negative contact point 120 of the earphone body 100. Specifically, since the charging case 1 has a charging slot 11, the earphone body 100 can be placed in the charging slot 11. Therefore, the earphone case can store the earphone body 100 to prevent it from being lost. The charging board assembly 2 includes a positive contact pin 211 and a negative contact pin 221. When the earphone body 100 is placed in the charging slot 11, the positive contact pin 211 and the negative contact pin 221 abut against the positive contact 110 and the negative contact 120 of the earphone body 100, respectively. Therefore, the earphone case can effectively store the earphone body 100. The normal charging function of the earphone body 100 is now ensured to guarantee the daily use of the earphone body 100. Since the axes of the positive contact pin 211 and the negative contact pin 221 are set in opposite directions, the flexibility and adaptability of the charging board assembly 2 are greatly improved. This makes the earphone case form a contoured contact pin structure that is adapted to the earphone body 100, so as to fit the complex and irregular surface of the earphone body 100, thereby maintaining effective contact with the contacts on the earphone body 100, so as to meet the charging performance requirements of the complex-shaped earphone body 100.
[0039] In this embodiment, the charging board assembly 2 has a positive electrode connection portion 21 and a negative electrode connection portion 22. Flexible circuit boards are provided on both the positive electrode connection portion 21 and the negative electrode connection portion 22. Positive electrode contact pin 211 and negative electrode contact pin 221 are electrically connected to the flexible circuit boards of the positive electrode connection portion 21 and the negative electrode connection portion 22, respectively. Both the positive electrode contact pin 211 and the negative electrode contact pin 221 are commonly used elastic contact pins in the art. The positive electrode contact pin 211 is retractably disposed on the positive electrode connection portion 21, and the negative electrode contact pin 221 is retractably disposed on the negative electrode connection portion 22 to achieve elastic contact with the contact point, thereby ensuring effective connection with the earphone body 100. The specific structure and working principle are not detailed here. It can be understood that the housing 1 has two charging slots 11 to realize the charging of the left and right earphone bodies 100, and the two charging slots 11 are symmetrically arranged. Correspondingly, the charging board assembly 2 has two positive electrode connection portions 21 and two negative electrode connection portions 22. Specifically, the charging plate assembly 2 also includes a mounting bracket 23, which connects the positive electrode connection portion 21 and the negative electrode connection portion 22 on both sides into a whole; the box body 1 includes a bottom shell 13 and an upper shell 14 that are snapped together, and there is a mounting cavity between the bottom shell 13 and the upper shell 14. The mounting bracket 23 is disposed in the mounting cavity. The bottom plate of the upper shell 14 is provided with a concave and convex structure to form a charging groove 11. The bottom plate of the upper shell 14 is provided with a through hole at the position corresponding to the charging groove 11, so that the positive electrode contact pin 211 and the negative electrode contact pin 221 are exposed in the charging groove 11 through the upper shell 14, and the positive electrode contact pin 211 and the negative electrode contact pin 221 can elastically extend and retract in the charging groove 11.
[0040] In order to effectively protect the earphone body 100 in the charging slot 11, the earphone case also includes a cover, which is connected to the case body 1 and can cover the charging slot 11.
[0041] Furthermore, on both the cover and the housing 1, one is provided with a first magnetic attractor and the other with a magnet, with the first magnetic attractor adhering to the magnet. In this embodiment, one end of the cover is rotatably connected to the housing 1. The cover is provided with the first magnetic attractor, and the housing 1 is provided with a magnet at the position corresponding to the first magnetic attractor. When the cover is rotated and fastened to the housing 1, the first magnetic attractor will adhere to the magnet, thereby preventing the cover from being easily opened and thus improving the protection of the earphone body 100 in the charging slot 11.
[0042] Furthermore, the cross-section at the positive contact 110 on the outer wall of the earphone body 100 is a first tangential plane, and when the positive contact pin 211 abuts against the positive contact 110, its axis is perpendicular to the first tangential plane; and / or, the cross-section at the negative contact 120 on the outer wall of the earphone body 100 is a second tangential plane, and when the negative contact pin 221 abuts against the negative contact 120, its axis is perpendicular to the second tangential plane. In this embodiment, the positive contact 110 has a first tangential plane, the positive contact pin 211 abuts against the first tangential plane and the axis of the positive contact pin 211 is perpendicular to the first tangential plane; the negative contact 120 has a second tangential plane, the negative contact pin 221 abuts against the second tangential plane and the axis of the negative contact pin 221 is perpendicular to the second tangential plane; the axis of the contact pin is perpendicular to the tangential plane, which ensures that the pressure applied to the contact pin by the contact is located on the axis of the contact pin, thereby reducing the risk of the contact being bent and damaged.
[0043] Furthermore, such as Figure 1 and Figure 2 As shown, the X-axis, Y-axis, and Z-axis form a spatial rectangular coordinate system, where the X-axis is the width direction of the headphone case, the Y-axis is the length direction of the headphone case, and the Z-axis is the height direction of the headphone case. The X-axis and Y-axis form the XY plane, the Y-axis and Z-axis form the YZ plane, and the X-axis and Z-axis form the XZ plane. The projection of the axis of the positive electrode contact 211 onto the XY plane is the first positive electrode projection line, and the projection of the axis of the negative electrode contact 221 onto the XY plane is the first negative electrode projection line. The angle between the first positive electrode projection line and the X-axis is 90°-135°, and the angle between the first negative electrode projection line and the X-axis is 45°-60°. The projection of the axis of the positive electrode contact 211 onto the YZ plane is the second positive electrode projection line, and the projection of the axis of the negative electrode contact 221 onto the YZ plane is the second negative electrode projection line. The angle between the second positive electrode projection line and the Y-axis is 10°-20°, and the angle between the second negative electrode projection line and the Y-axis is 20°-45°. The projection of the axis of the positive electrode contact 211 onto the XZ plane is the third positive electrode projection line, and the projection of the axis of the negative electrode contact 221 onto the XZ plane is the third negative electrode projection line. The angle between the third positive electrode projection line and the Z-axis is 3°-10°, and the angle between the third negative electrode projection line and the Z-axis is 20°-45°.
[0044] Specifically, the angles between each positive and negative projection line and each coordinate axis can be set according to actual conditions, as long as they are perpendicular to the contacts on the earphone body 100. In this embodiment, the angle between the first positive projection line and the X-axis is 103.7°, the angle between the second positive projection line and the Y-axis is 12.8°, and the angle between the third positive projection line and the Z-axis is 4.8°; the angle between the first negative projection line and the X-axis is 50.1°, the angle between the second negative projection line and the Y-axis is 29.2°, and the angle between the third negative projection line and the Z-axis is 24.4°. It can be understood that the positive contact pins 211 and 221 of the same earphone body 100 are asymmetrically arranged, and the tilt directions of the positive contact pins 211 and 221 are different, so as to maintain effective contact with the positive contacts 110 and 120 on the irregular earphone body 100.
[0045] This embodiment also provides an earphone, which includes an earphone body 100 and the aforementioned earphone case. The earphone body 100 is placed in the charging slot 11 of the case 1. In this embodiment, the positive electrode contact pin 211 and its axis are arranged opposite to the axis of the negative electrode contact pin 221, rather than being simply parallel or asymmetrical. Therefore, a contoured structure adapted to the earphone body 100 is formed to meet the charging requirements of the irregularly shaped earphone body 100.
[0046] Furthermore, such as Figure 2 and Figure 3 As shown, a second magnetic element 12 is provided in the charging slot 11, and the second magnetic element 12 is attracted to the earphone body 100. In this embodiment, after the earphone body 100 is placed in the charging slot 11, the second magnetic element 12 will attract the magnet in the earphone body 100, thereby fixing the earphone body 100 in the charging slot 11 and preventing the earphone body 100 from accidentally falling out of the charging slot 11.
[0047] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
