Description

Technical Field

[0001] This application belongs to the field of wearable device technology, and in particular relates to a pair of headphones. Background Technology

[0002] The continuous evolution of headphones has provided people with an increasingly superior listening experience. Early headphone devices relied on physical buttons to determine whether they were being worn. With the development of related technologies, headphones can now accurately identify whether they are being worn by sensing pressure on the auricle and changes in ear canal temperature. This not only avoids manual operation but also reduces headphone power consumption through intelligent start / stop.

[0003] Modern headphones employ ergonomic designs that fit the ear more closely to improve wearing comfort. However, the internal space of headphones is limited. To improve battery life, noise cancellation, and other performance aspects, the internal components need to be more compact to provide space for the main components and reduce costs.

[0035] Please see Figure 1 and Figure 3 The present application provides an earphone 100, which includes a first housing 10 and a vibrator metal bracket 20.

[0036] The vibrator metal bracket 20 is installed in the first housing 10. The vibrator metal bracket 20 is provided with a detection interface 24. The voltage of the detection interface 24 is different when the earphone 100 is worn and not worn.

[0037] The detection interface 24 is used for wearing detection. When the vibrator metal bracket 20 moves from away from the human body (such as the ear) to contact the human body, the capacitance of the air medium between the vibrator metal bracket 20 and the human skin suddenly increases from its original fixed capacitance value, which will cause a sudden change in the voltage of the detection interface 24 (such as an increase). Based on the value of the voltage of the detection interface 24, it can be determined whether the earphone 100 is being worn.

[0038] For example, when the earphone 100 is worn, the voltage of the detection interface 24 is within a first preset voltage range; when the earphone 100 is not worn, the voltage of the detection interface 24 is within a second preset voltage range. By periodically acquiring the voltage of the detection interface 24 and determining whether the acquired voltage is within the first or second preset voltage range, it is possible to accurately determine whether the earphone 100 is being worn.

[0039] The first preset voltage range is different from the second preset voltage range because the voltage range is set according to the electrical system inside the corresponding earphone 100.

[0040] In this way, wear detection can be accurately achieved, avoiding repeated alternation in determining whether the earphone 100 is worn or not, thus improving the stability and safety of the earphone 100.

[0041] Optionally, the edge shape of the oscillator metal bracket 20 can be a ring-shaped composite shape (similar to a racetrack shape), an open C-shaped shape, an I-shaped shape, or a shape that matches other components. The material of the oscillator metal bracket 20 can be phosphor bronze, beryllium bronze, austenitic stainless steel, aluminum alloy, etc. This application embodiment does not limit this.

[0042] By reusing the vibrator metal bracket 20, wear detection can be accurately achieved, and additional wear detection sensors can be avoided, saving internal space of the earphone 100 and reducing production costs.

[0043] In some embodiments, please refer to Figure 2 The earphone 100 also includes a second housing 30 and a wear detection circuit 31; the wear detection circuit 31 is disposed in the second housing 30, the wear detection circuit 31 is connected to the detection interface 24, and the wear detection circuit 31 is used to detect the voltage of the detection interface 24 for wear detection.

[0044] The wear detection circuit 31 can detect the voltage value of the detection interface 24 at regular intervals (e.g., 0.1ms), and compare the voltage value obtained at regular intervals with the first preset voltage and the second preset voltage to accurately determine whether the earphone 100 is in the wearing state.

[0045] Optionally, the wear detection circuit 31 can be set in the first housing 10 to improve the detection speed of wear detection and reduce the space occupied by the second housing 30.

[0046] In some embodiments, please refer to Figure 3 The oscillator metal bracket 20 includes a sensing area 21 and a support area 22. The support area 22 is arranged around the sensing area 21 and is at least partially hollowed out.

[0047] The sensing area 21 is located in the central area of ​​the oscillator metal bracket 20 and is the main wear detection area. The larger the area of ​​the sensing area 21, the greater the capacitance value and the greater the change, and the better the wear detection effect.

[0048] Optionally, the sensing area 21 can be Figure 3The rectangular area represented by the dashed line in the figure can also be a polygon or an irregular polygon, such as an equilateral triangle or a parallelogram. This application does not limit this.

[0049] The hollowed-out support area 22 surrounds the sensing area 21, which can enhance the sound effect of the headphones 100, reduce the resonance interference of the vibrator metal bracket 20 and the metal shielding effect, and also improve the heat dissipation speed of the headphones 100 during charging, avoid high-temperature aging of internal components, and enhance the service life of the headphones 100.

[0050] Furthermore, the partially hollowed-out support area 22 can reduce the weight of the earphone 100, reduce the pressure of the earphone 100 on the ear canal, and improve the wearing comfort of the earphone 100.

[0051] Optionally, the hollow pattern of the support area 22 can be a combination or splicing of geometric patterns, biomimetic patterns, random patterns, etc., while ensuring the continuity of the sensing area 21, reasonable structural mechanics, and complete acoustic path. This application embodiment does not limit this.

[0052] The detection interface 24 is connected to the edge of the support area 22 via a wire to avoid affecting the wearing detection effect.

[0053] In some embodiments, please refer to Figure 1 , 4 5. The first housing 10 includes a bottom wall 11 and a side wall 12 disposed around the bottom wall 11. The earphone 100 also includes a bracket assembly 40 disposed on the bottom wall 11, and a vibrator metal bracket 20 disposed on the bracket assembly 40.

[0054] The bottom wall 11 and the side wall 12 form an open receiving space to protect various internal components (such as the bracket assembly 40, the oscillator metal bracket 20, etc.). The center of the face of the bracket assembly 40 and the oscillator metal bracket 20 opposite to the bottom wall 11 is on the same straight line as the center of the face of the bottom wall 11 to ensure the regularity and stability of the first housing 10.

[0055] Optionally, the bottom wall 11 and the side wall 12 can be made of materials such as PC plastic, aluminum alloy, ceramic, glass fiber reinforced plastic, etc., and this application embodiment does not limit this.

[0056] The material of the support assembly 40 can be engineering plastics (such as polyoxymethylene, liquid crystal polymer), thermoplastic polyurethane, glass fiber reinforced plastic, etc., and this application embodiment does not limit it.

[0057] The shape of the support assembly 40 ensures that it can be located in the receiving space formed by the bottom wall 11 and the side wall 12. For example, it can be a double semi-circular straight-edged column, etc. This application embodiment does not limit this.

[0058] In some embodiments, please refer to Figure 3 , 4 5. The bracket assembly 40 includes a support member 50 and a fixing member 60. The support member 50 is disposed on the bottom wall 11 and has a mounting hole 70. The fixing member 60 passes through the mounting hole 70 to fix the first housing 10, the support member 50 and the vibrator metal bracket 20 together.

[0059] Optionally, the support member 50 has two mounting holes 70, which are formed on the surface of the support member 50 parallel to the bottom wall 11, and both holes penetrate the entire support member 50 and are symmetrical about the face center of the support member 50. This enhances symmetry and installation flexibility, allows the support member 50 to be subjected to uniform force, and improves overall stability.

[0060] Optionally, the mounting holes 70 of the support member 50 can be one or more, and the mounting holes 70 are all opened on the plane of the support member 50 and the bottom wall 11, and penetrate the entire support member 50. The relationship between the mounting holes 70 and the face center of the support member 50 is not limited.

[0061] The shape of the mounting hole 70 can be a circular hole, a square hole, or other shapes, and this application embodiment does not limit this.

[0062] In some embodiments, please refer to Figure 4 , 7 The earphone 100 also includes a cover 80 and a vibrator 90; the cover 80 is disposed in the first housing 10; the bottom wall 11, the side wall 12, the outer wall 55 of the support member 50 and the inner wall of the cover 80 form a vibration space, and the vibrator 90 is disposed in the vibration space.

[0063] The cover 80 and the bottom wall 11 are arranged on two opposing surfaces of the support member 50. The outer wall 55 of the support member 50 and the side wall 12 are in close contact, with a certain distance between them. The vibrator 90 is arranged in the vibration space formed by the bottom wall 11, the side wall 12, the outer wall 55 of the support member 50 and the inner wall of the cover 80.

[0064] Optionally, the overall shape of the cover 80 matches the bottom wall 11 and can be tightly integrated with the side wall 12 to ensure the stability of the vibration space. The overall shape of the cover 80 can be a ring-shaped composite shape (similar to a runway shape), etc., and this embodiment does not limit it.

[0065] In some embodiments, please refer to Figure 8 The oscillator 90 is in the shape of a ring and is arranged around the support member 50.

[0066] The shape of the oscillator 90 matches the vibration space formed by the bottom wall 11, the side wall 12, the outer wall 55 of the support member 50 and the inner wall of the cover 80, and can vibrate in the vibration space. The shape of the oscillator 90 can be ring, polygon, etc., and the material of the oscillator 90 can be copper, aluminum, silver-plated copper, etc. The embodiments of this application do not limit this.

[0067] Optionally, please refer to Figure 2 The oscillator 90 includes a positive interface 91 and a negative interface 92, and the second housing 30 also includes a sound-generating circuit 32. Both the positive interface 91 and the negative interface 92 are physically connected to the sound-generating circuit 32. The audio electrical signal generated by the sound-generating circuit 32 is accurately transmitted to the oscillator 90 through the positive interface 91 and the negative interface 92, so that the oscillator 90 can convert the received audio electrical signal into corresponding mechanical vibration to ensure accurate sound reproduction and stereo effect.

[0068] In some embodiments, please refer to Figure 7 and 9 The inner wall of the cover 80 is provided with an annular protrusion 82, and the vibrator 90 is located between the annular protrusion 82 and the bottom wall 11. The distance between the annular protrusion 82 and the bottom wall 11 is less than the distance between the vibrator metal support 20 and the bottom wall 11.

[0069] The annular protrusion 82 separates the oscillator 90 and the oscillator metal bracket 20 to prevent the electrical signals in the oscillator 90 from interfering with the electrical parameters in the oscillator metal bracket 20, thereby ensuring that the reused oscillator metal bracket 20 can achieve accurate wear detection.

[0070] In some embodiments, please refer to Figure 1 , 2 6 and 9, the cover 80 has multiple through holes, and the wires of the detection interface 24, the positive interface 91 and the negative interface 92 pass through the corresponding through holes to connect with the corresponding circuits in the second housing 30.

[0071] Optionally, the through holes may include three or more, with shapes and sizes that allow wires to pass through, to ensure the wires of the detection interface 24, the positive interface 91, and the negative interface 92, without limitation.

[0072] In some embodiments, please refer to Figure 3 , 4 5. The oscillator metal bracket 20 includes a sensing area 21 and a support area 22. The bottom wall 11 has a first fixing hole 13 and the support area 22 has a second fixing hole 23. The fixing member 60 passes through the first fixing hole 13, the mounting hole 70 and the second fixing hole 23 in sequence.

[0073] The shapes of the first fixing hole 13 and the second fixing hole 23 match the mounting hole 70 to ensure that the fastener 60 can pass through the first fixing hole 13, the mounting hole 70 and the second fixing hole 23 appropriately and stably. This enhances the connection stability between the bottom wall 11, the support area 22 and the vibrator metal bracket 20.

[0074] Furthermore, the number of the first fixing hole 13 and the second fixing hole 23 is greater than or equal to the number of mounting holes 70.

[0075] In some embodiments, please refer to Figure 4 and 5 The outer diameter of the fastener 60, the inner diameter of the first fixing hole 13, the inner diameter of the mounting hole 70, and the inner diameter of the second fixing hole 23 are the same.

[0076] This ensures the stability of the fastener 60 as it passes through the first fixing hole 13, the mounting hole 70, and the second fixing hole 23 in sequence, preventing movement between components and thus avoiding component damage.

[0077] In some embodiments, please refer to Figure 4 and 5 The fastener 60 includes a body 61 and a first lug 62 and a second lug 63 located at both ends of the body 61. The outer diameter of the body 61, the inner diameter of the first fixing hole 13, the inner diameter of the mounting hole 70 and the inner diameter of the second fixing hole 23 are the same. The outer diameters of the first lug 62 and the second lug 63 are both larger than the outer diameter of the body 61. The first lug 62 abuts against the surface of the bottom wall 11 opposite to the support member 50, and the second lug 63 abuts against the surface of the vibrator metal bracket 20 opposite to the support member 50.

[0078] This makes the combination of the bottom wall 11, the support 50 and the oscillator metal bracket 20 more stable.

[0079] Optionally, the outer diameters of the first lug 62 and the second lug 63 are appropriately larger than the outer diameter of the body 61 to avoid the second lug 63 being too large, which would excessively obstruct the sensing area 21 and the support area 22 of the vibrator metal bracket 20 and affect the accuracy of the wear detection.

[0080] Optionally, the outer wall of the fastener 60 may be threaded, and the inner walls of the corresponding first fixing hole 13, mounting hole 70 and second fixing hole 23 may have matching threads; the fastener 60 tightly combines the first fixing hole 13, mounting hole 70 and second fixing hole 23 together by screwing.

[0081] In some embodiments, please refer to Figure 4 , 57. Support member 50 includes a first support member 51 and a second support member 54. The second support member 54 is disposed on the first support member 51. The orthographic projection of the second support member 54 on the surface of the first support member 51 is located inside the first support member 51. Mounting hole 70 includes a first mounting hole 71 and a second mounting hole 74. The first support member 51 has the first mounting hole 71, and the second support member 54 has the second mounting hole 74. The central axes of the first mounting hole 71 and the second mounting hole 74 coincide.

[0082] The first support member 51 and the second support member 54 have similar overall shapes, both being ring-shaped composites (similar to the shape of a runway).

[0083] The size of the surface parallel to the second support member 54 and the bottom wall 11 is smaller than the size of the surface parallel to the first support member 51 and the bottom wall 11.

[0084] The first mounting hole 71 and the second mounting hole 74 are matched (the inner diameters are equal and the central axes coincide).

[0085] Optionally, the overall shape of the second support 54 and the first support 51 may be different, but the first mounting hole 71 and the second mounting hole 74 are matched (the inner diameters are equal and the central axes coincide).

[0086] In some embodiments, please refer to Figure 4 , 5 7. The first support member 51 includes a first sub-support member 52 and a second sub-support member 53.

[0087] The second sub-support 53 is disposed on the first sub-support 52, and the first sub-support 52 is matched with the second sub-support 53. The orthographic projection of the second sub-support 53 onto the surface of the first sub-support 52 is located in the first sub-support 52. The first mounting hole 71 includes a first sub-mounting hole 72 and a second sub-mounting hole 73. The first sub-support 52 has the first sub-mounting hole 72, and the second sub-support 53 has the second sub-mounting hole 73. The inner diameters of the first sub-mounting hole 72 and the second sub-mounting hole 73 are equal, and their central axes coincide.

[0088] Optionally, the thickness of the first sub-support member 52 in the direction perpendicular to the bottom wall 11 is less than, equal to, or greater than the thickness of the second sub-support member 53 in the direction perpendicular to the bottom wall 11, which is not limited here.

[0089] Optionally, the first support member 51 may include a plurality of matching sub-support members.
