Description

Technical Field

[0001] The present disclosure generally relates to the field of electronic product technology. More specifically, the present disclosure relates to a headset. Background Art

[0002] With the development of wireless communication technology, headphones are becoming increasingly popular among consumers due to their portability and wireless freedom. Headphones can generally be divided into two types: open wearable stereo headphones (OWS) and true wireless stereo headphones (TWS).

[0003] While the design of headphones has become increasingly sophisticated, their size has also been shrinking. This has led to a shrinking internal space, which in turn has reduced the available space for various components. In particular, the space for the antenna inside the headphone has been squeezed ever smaller, posing significant challenges to antenna design. Specifically, as the antenna area shrinks, its radiation efficiency and directionality are affected, potentially resulting in Bluetooth connection failures or weak signal conditions.

[0004] Due to structural space limitations, OWS and TWS earphones can only have one antenna designed for each left and right earphone. Furthermore, the placement of the antenna is also affected by the earphone chip and other components, which limits the antenna performance. Furthermore, especially for OWS earphones, because the wearing angle is related to the shape of the human ear, the position or angle at which each person wears the earphones varies more significantly from consumer to consumer. This results in different effects on the antenna when worn, leading to significant differences in antenna performance or radiation direction. Ultimately, different people experience different effects when using the earphones in the same environment. For example, in the same environment, some people may experience audio freezes and disconnections due to interference, while others may not experience these issues.

[0005] In view of this, there is an urgent need to provide a solution for headphones to improve the antenna radiation range of the headphones, thereby reducing problems such as sound freezes and connection disconnections. Utility Model Content

[0033] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0034] Example application scenarios

[0035] Figure 1a Figure 2 shows a schematic diagram of the structure of the human ear. Figure 1a As shown, the visible area of the ear may include the helix 101, the scaphoid 102, the cavum concha 103, the antihelix 104, the earlobe 105, the tragus 106, the cavum concha 107, and the triangular fossa 108. In some embodiments, the earphones may be supported by one or more parts of the human ear to ensure stable wearing.

[0036] Figure 1b A schematic diagram showing headphones according to some embodiments of the present disclosure being worn on a human ear is shown. Figure 2 An exemplary structural diagram of an earphone according to an embodiment of the present disclosure is shown.

[0037] like Figure 1b as well as Figure 2 As shown, in some embodiments, the earphone may include: an earphone main body 10; a power supply component 20; a connecting component 30 and a first antenna 40, wherein, when worn, the earphone main body 10 is located in the concha cavity 107 area of the ear, the first end of the connecting component 30 is connected to the earphone main body 10 and extends from the earphone main body 10 to the area between the ear and the head, and is connected to the power supply component 20 at the second end of the connecting component 30; and the power supply component 20 is arranged in a first accommodating cavity formed by the earphone shell 21, and the first antenna 40 is arranged on the earphone shell 21 constituting the first accommodating cavity.

[0038] In some embodiments, the earphone body 10 can be connected to the connecting component 30. The earphone body 10 can have a stepped shape. The earphone body 10 can include a lower portion and an upper portion. The lower portion can be cylindrical, and the upper portion can be an elongated cylindrical shape. It should be understood that the bottom surface of the elongated cylindrical shape can be composed of two parallel long sides and two arcs connecting the two parallel long sides.

[0039] In some embodiments, when worn, the earphone body 10 can be positioned in the cavum concha 107 region of the ear. The first end of the connecting component 30 can be connected to the earphone body 10, extending from the earphone body 10 to the region between the ear and the head. The second end of the connecting component 30 is connected to the power supply component 20. It will be appreciated that, when worn, one end of the lower portion of the earphone body can face the cavum concha 107, the other end of the lower portion can be connected to one end of the upper portion of the earphone body, the other end of the upper portion can be connected to the first end of the connecting component, and the second end of the connecting component 30 can be connected to the power supply component 20. In some embodiments, the outer shell of the earphone body 10 can be transparent to enhance the aesthetics of the earphone.

[0040] In some embodiments, the earphone body 10 may be internally provided with components such as a chip, a speaker, and a microphone. The chip may be provided with a Bluetooth module, a control module, an audio decoding module, etc. The speaker may convert electrical signals into sound signals, and the microphone may be used to capture sound.

[0041] In some embodiments, the power supply component 20 can be connected to the connecting component 30, and the power supply component 20 can include a built-in battery. The built-in battery can be a rechargeable built-in battery or a non-rechargeable built-in battery. If the built-in battery is a non-rechargeable battery, it can be powered by replacing the built-in battery; if the built-in battery is a rechargeable battery, it can be charged by wired charging or wireless charging. Specifically, when using wired charging, the built-in battery can be placed in a charging box, and the charging box can be connected to an external power source via a micro Universal Serial Bus (USB) or Type-C interface for charging. When using wireless charging, a wireless charging receiver module can be integrated into the headset to charge the built-in battery. When the built-in battery is a rechargeable battery, the headset can also be powered by replacing the built-in battery. In some embodiments, the headset housing 21 can form a first accommodating cavity, the power supply component 20 can be placed in the first accommodating cavity, and the first antenna 40 can be placed on the headset housing 21 constituting the first accommodating cavity.

[0042] In some embodiments, the earphone housing 21 may include a shell of the power supply component 20. The shell of the power supply component 20 may form the first antenna 40 in its entirety or in part. The larger the area of the first antenna 40, the higher the radiation efficiency of the first antenna 40. In some embodiments, a first circuit 41 may be provided in the first accommodating cavity, and the first antenna 40 may be connected to the power supply component 20 via the first circuit 41. By placing the first antenna 40 and the first circuit 41 in the first accommodating cavity instead of the earphone body 10, connection costs and the volume of the earphone body 10 can be reduced. Furthermore, signal loss, especially high-frequency signal loss, can be reduced.

[0043] It should be understood that the earphone housing 21 is at least partially metal, forming the radiating portion of the first antenna. The metal portion of the earphone housing 21 can be configured as the first antenna 40. When the earphone housing 21 is entirely metal, the entire earphone housing 21 can serve as the first antenna 40, and the entire metal housing can form the radiating portion of the first antenna, thereby increasing the radiation efficiency of the first antenna 40.

[0044] In some embodiments, the power supply component 20 can be located outside the earphone housing 21. It should be understood that in this case, the power supply component 20 can be an element that receives power externally from the earphones. In this case, the interior of the first housing cavity formed by the earphone housing 21 can be empty to reduce battery interference with the first antenna. A chip can also be placed inside the first housing cavity to reduce the volume of the earphone body 10.

[0045] In some embodiments, one end of the connecting component 30 can be connected to the earphone body 10, and the other end of the connecting component 30 can be connected to the power supply component 20. The connecting component 30 can be provided with a memory wire, a power line, a signal line, etc.

[0046] By disposing the aforementioned first antenna 40, the radiation direction of the antenna can be increased and the volume of the earphone can be reduced.

[0047] In some embodiments, a first filtering circuit 42 may be connected between the aforementioned first antenna 40 and the power supply component 20, or a magnetic isolation sheet may be provided between the first accommodating cavity and the battery core of the power supply component 20, which may be used to reduce the interference of the power supply component 20 on the first antenna 40. In some embodiments, when the operating frequency band of the first antenna 40 is relatively high, for example, 2.4 GHz or higher, the operating frequency of the power supply component is relatively low, and the power supply component has less influence on the first antenna 40 at this time. When the operating frequency band of the first antenna 40 is relatively low, the interference of the power supply component 20 on the first antenna 40 may be reduced by providing a first filtering circuit 42 or a magnetic isolation sheet. In some embodiments, the aforementioned filtering circuit 42 may include an LC filtering circuit or a filter, wherein the aforementioned filter may be a surface acoustic wave filter (SAW), a low-pass filter, a high-pass filter, a band-pass filter or a band-stop filter. Preferably, a surface acoustic wave filter may be selected, which has the characteristics of small size, light weight, stable performance, and good manufacturing repeatability. In some embodiments, the aforementioned magnetic isolation sheet may be used to isolate the magnetic field and reduce magnetic interference.

[0048] In some embodiments, the aforementioned earphone may also include a first circuit 41 connected to the first antenna 40, and the aforementioned first circuit 41 may be set in the earphone shell 21; the aforementioned first circuit 41 may be set in the earphone body 10 and connected to the first antenna 40 through the connecting component 30; or the aforementioned first circuit 41 may be set outside the earphone shell 21 and the earphone body 10.

[0049] In some embodiments, when the first circuit 41 is disposed within the earphone housing 21, the first antenna 40 may be connected to the first circuit 41 via a feed point and / or a feed point. The feed point and / or feed point may be connected in the form of a spring. It will be appreciated that locating the first circuit 41 and the power supply component 20 together can reduce the size of the earphone and reduce signal loss during signal transmission.

[0050] In some embodiments, the first circuit 41 is disposed in the earphone body 10, and when connected to the first antenna 40 via the connecting component 30, the location where the connecting component 30 is connected to the earphone body 10 can be a feeding point and / or a feeding ground. In some embodiments, the first circuit 41 can also be disposed outside the power supply component 20 and the earphone body 10. For example, the first circuit 41 can be disposed inside the connecting component 30. By separating the first circuit 41 and the first antenna 40, interference with the first antenna 40 by electronic components can be reduced, and the gain performance of the first antenna can also be increased.

[0051] In some embodiments, the headset may further include a second antenna 50, which may be disposed within the headset body 10. The second antenna 50 may be disposed within the headset body 10 or on the housing of the headset body 10. Specifically, when the second antenna is disposed within the headset body 10, the headset body 10 may include an antenna bracket, on which the second antenna 50 may be disposed, and the antenna bracket may be connected to the second circuit. When the second antenna 50 is disposed on the housing of the headset body 10, the housing may include a metal area, which may form the second antenna 50.

[0052] In some embodiments, the first antenna 40 can operate in the 1.8 GHz, 2.1 GHz, 2.4 GHz, or 5 GHz frequency bands; the second antenna 40 can operate in the 1.8 GHz, 2.1 GHz, 2.4 GHz, or 5 GHz frequency bands. When the first antenna 40 and the second antenna 50 operate simultaneously, the operating frequency bands are different. In some embodiments, when only the first antenna is operating, the operating frequency band of the first antenna 40 can be the 2.4 GHz frequency band, in which case it can be used for Bluetooth. The operating frequency band of the first antenna 40 can be the 5 GHz frequency band, which can be used for wireless local area networks.

[0053] In some embodiments, the headset may further include a first switch 70, which may be connected to the first antenna 40 and the second antenna 50 and configured to switch the operating states of the first antenna 40 and the second antenna 50. In some embodiments, the first switch 70 may be a switch circuit, a mechanical switch, a button switch, a relay switch, a transistor switch, or the like.

[0054] In some embodiments, the first switch 70 may be indirectly connected to the first antenna 40, and the first switch 70 may also be indirectly connected to the second antenna 50. Specifically, a first end of the first switch 70 may be connected to one end of the first antenna circuit 41, a second end of the first antenna circuit 41 may be connected to one end of the second antenna circuit 51, the other end of the first antenna circuit 41 may be connected to the first antenna 40, and the other end of the second antenna circuit 51 may be connected to the second antenna 50.

[0055] It is understood that when the first switching switch 70 is connected to the first antenna circuit 41 and disconnected from the second antenna circuit 51, the first antenna 40 can be in an operating state and the second antenna 50 can be in a disconnected state. In this case, the operating frequency band of the first antenna can be the 1.8 GHz band, the 2.1 GHz band, the 2.4 GHz band, or the 5 GHz band. Specifically, when the operating frequency band is the 2.4 GHz band, the first antenna can function as Bluetooth. When the first switching switch 70 is connected to the second antenna circuit 51 and disconnected from the first antenna circuit 41, the second antenna 50 can be in an operating state and the first antenna 40 can be in a disconnected state. In this case, the operating frequency band of the second antenna can be the 1.8 GHz band, the 2.1 GHz band, the 2.4 GHz band, or the 5 GHz band.

[0056] In some embodiments, the first antenna 40 and the second antenna 50 can be in operation simultaneously. In this case, the operating frequency bands of the first antenna 40 and the second antenna 50 can be different. For example, the operating frequency band of the first antenna 40 can be the 2.4 GHz band, which can be used for Bluetooth, and the operating frequency band of the second antenna 50 can be the 5 GHz band, which can be used for wireless local area networks. It should be understood that when the first antenna 40 is connected, the radiation direction of the first antenna 40 can be different from the radiation direction of the second antenna 50 when it is connected. The radiation direction of the first antenna 40 and the radiation direction of the second antenna 50 will be described in detail later.

[0057] In some embodiments, the headset may further include a first signal comparator 71, which may be connected to the first switch 70. The first signal comparator 71 may be configured to receive signal states from the first antenna 40 and the second antenna 50, and control switching of the first switch 70 based on the signal states. In some embodiments, a first end of the first switch 70 may be connected to the first antenna 40, a second end of the first switch 70 may be connected to the second antenna 50, and a third end of the first switch 70 may be connected to the first signal comparator 71.

[0058] In some embodiments, the first signal comparator 71 may include a first detection module and a first control module, wherein the first detection module may be used to receive the signal status of the first antenna 40 and the second antenna 50, and the first control module may be used to control the switching of the first switch 70 based on the signal status. In some embodiments, the signal status may include the strength of the antenna signal.

[0059] In some embodiments, the first control module may control the first switch 70 to switch after a preset time interval. For example, the first control module may connect the first switch 70 to the first antenna 40, at which point the first detection module may detect the antenna signal strength of the first antenna 40. After a preset time interval, the first control module may connect the first switch 70 to the second antenna 50, at which point the first detection module may detect the antenna signal strength of the second antenna 50.

[0060] After obtaining the signal strength of the first antenna and the second antenna, the first control module can control the first switching switch 70 based on the antenna signal strength of the first antenna 40 and the antenna signal strength of the second antenna 50. When the antenna signal strength of the first antenna 40 is greater than the antenna signal strength of the second antenna 50, the first control module controls the first switching switch 70 to be connected to the first antenna 40; when the antenna signal strength of the first antenna 40 is less than the antenna signal strength of the second antenna 50, the first control module controls the first switching switch 70 to be connected to the second antenna 50.

[0061] In some embodiments, when worn, the earphone body 10 can be located in the concha area of the ear, and the first end of the connecting component 30 can be connected to the earphone body, extending from the earphone body 10 to the area between the ear and the head, and connected to the power supply component 20 at the second end of the connecting component 30; the radiating portion of the first antenna 40 is arranged in the direction toward the open area clamped between the head and the ear; the radiating portion of the second antenna is arranged in the direction of the earphone body away from the concha.

[0062] In some embodiments, since the radiating portion of the first antenna 40 is positioned toward the open area between the head and the ear, when in operation, the radiation direction of the first antenna 40 may include directions toward the open area between the head and the ear, such as toward the rear, above, or below the ear. The second antenna 50 may be positioned on the earphone body 10, and its radiation direction may include directions from the earphone body away from the cavum concha, such as toward the front, above, or below the ear. It should be noted that the aforementioned radiation directions are merely exemplary.

[0063] like Figure 1b As shown, in some embodiments, the radiation direction of the first antenna 40 can be toward the open area between the head and the ear. The radiation direction of the first antenna 40 can include radiation direction 1 and radiation direction 2. Radiation direction 1 can include the direction toward the back of the ear in the open area between the head and the ear, and radiation direction 2 can include the direction from the ear to the foot when the person is standing. In some embodiments, the radiation direction of the second antenna 50 can be various directions from the earphone body to the cavum concha away from the ear. The radiation direction of the second antenna 50 can include radiation direction 3 and radiation direction 4. Radiation direction 3 can include the direction from the earphone body to the front of the ear away from the cavum concha, and radiation direction 4 can include the direction from the ear to the foot when the person is standing. It is understood that radiation direction 1 and radiation direction 3 can be different, and radiation direction 2 and radiation direction 4 can be the same. The configuration of the first antenna 40 and the second antenna 50 can increase the radiation range of the earphone antenna.

[0064] It should be understood that when worn, the radiation direction of the first and second antennas can both be downward. In some embodiments, the energy radiated downward by the first and second antennas can be greater than the energy radiated toward the surroundings and toward the sky. It should be understood that when worn, the downward radiation direction of the first and second antennas can be toward the feet of a person standing.

[0065] It can be understood that by setting the aforementioned first antenna and the second antenna, the radiation direction of the aforementioned first antenna 40 can be different from the radiation direction of the aforementioned second antenna 50, which can increase the radiation range of the headphone antenna and solve the problem of connection jams and disconnections caused by different wearing methods or changes in the surrounding environment when different users use headphones.

[0066] In some embodiments, the aforementioned earphones may only have the first antenna 40. It is understandable that, since there is no antenna inside the earphone body 10, the interior of the earphone body 10 can have more design space than if the antenna were set inside the earphone body 10. Other components can be added inside the earphone body 10, thereby increasing the functionality of the earphones. It should be understood that since there is no antenna inside the earphone body 10, when designing the interior of the earphones, requirements such as clearance requirements, RF routing requirements, metal device requirements, and matching device layout requirements caused by the installation of an antenna can be avoided, thereby increasing the design options inside the earphone body 10 and increasing diversity. In addition, when designing the antenna, since the antenna is not inside the earphone body, restrictive antenna designs due to internal space limitations of the earphone body can be avoided.

[0067] In some embodiments, in addition to the first antenna 40, a portion of the housing of the power supply component 20 may also be formed into a connecting component 30. The housing of the power supply component 20 and the connecting component 30 may be integrally formed. In some embodiments, antennas may be provided on both the housing of the power supply component 20 and the housing of the connecting component 30. This allows the antennas to be unaffected by the motherboard and maximizes the utilization of the motherboard's area, thereby covering more frequency bands and ultimately achieving better antenna radiation effects.

[0068] In some embodiments, a first antenna 40 may be provided on the housing of the power supply component 20, and a chip may be provided in the power supply component 20, and the chip and the first antenna 40 may be connected. This arrangement reduces wiring usage compared to placing the chip inside the earphone body 10 and connecting it to the first antenna 40. Furthermore, the chip can be made independent of the earphone body, thereby simplifying the design.

[0069] In some embodiments, the first antenna 40 can be set on the housing of the power supply component 20. When worn, the orientation of the aforementioned first antenna 40 can include a downward direction, which is more conducive to radiation to an electronic device equipped on the body (for example, a mobile phone equipped in a pocket). Compared with the direction of the earphone body 10, setting the antenna on the housing of the power supply component 20 is more conducive to the connection between the earphone and the device, wherein the aforementioned downward direction can include the direction from the head to the feet of the human body when the human body is standing.

[0070] Figure 3a A circuit schematic diagram of the first antenna and the second antenna of some embodiments of the present disclosure is shown.

[0071] like Figure 3aAs shown, the earphone may include a first antenna 40 , a first antenna circuit 41 , a first filtering circuit 42 , a second antenna 50 , a second antenna circuit 51 , a first switch 70 and a first signal comparator 71 .

[0072] In some embodiments, the aforementioned first antenna 40 can be connected to the first end of the first antenna circuit 41, the second end of the aforementioned first antenna circuit 41 can be connected to the first end of the first filter circuit 42, the second end of the aforementioned first filter circuit 42 can be connected to the first end of the aforementioned first switching switch 70, the aforementioned second antenna 50 can be connected to the first end of the second antenna circuit 51, the second end of the aforementioned second antenna circuit 51 can be connected to the second end of the aforementioned first switching switch 70, and the third end of the aforementioned first switching switch 70 can be connected to the aforementioned first signal comparator 71.

[0073] In some embodiments, when the first switch 70 is connected to the first antenna circuit 41 and disconnected from the second antenna circuit 51, the first antenna 40 can be in an active state and the second antenna 50 can be in a disconnected state. In this case, the operating frequency band of the first antenna can be 1.8 GHz, 2.1 GHz, 2.4 GHz, or 5 GHz. When the operating frequency band is 2.4 GHz, the first antenna can function as Bluetooth. When the first switch 70 is connected to the second antenna circuit 51 and disconnected from the first antenna circuit 41, the second antenna 50 can be in an active state and the first antenna 40 can be in a disconnected state. In this case, the operating frequency band of the second antenna can be 1.8 GHz, 2.1 GHz, 2.4 GHz, or 5 GHz.

[0091] In some embodiments, when the earphones are worn, the connecting member 30 extends from the front of the ear, along the earphone body 10, to the back of the ear, and is mounted on the ear.
