Description

Headset

Technical Field

The invention relates to the technical field of electroacoustic conversion, in particular to a headphone.

Background

The real wireless earphone (TWS) is connected with external equipment (such as a mobile phone, a computer and the like) through the wireless communication module, and an earphone wire is not required to be arranged for transmitting audio signals, so that the interference problem of the earphone wire is avoided.

In the existing wireless headset, two independent headset devices are connected through a wire hidden in the headband body, so that the two headset devices are electrically connected and connected through a signal. The distance between the two earphone bodies cannot be arbitrarily extended due to the connection of the wires.

In addition, such a connection structure makes replacement of the earphone device difficult when one of the earphone devices fails.

In addition, in a normal case, one of the two headphone apparatuses serves as a main headphone including a signal receiving unit, a power supply, and the like, and the other one serves as a sub-headphone, which is not provided. This causes inconsistency in the function and structure of the earphone device, and poor replaceability.

Therefore, a new technical solution is needed to solve the above technical problems.

It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.

According to one embodiment of the present disclosure, a headset is provided. As shown in fig. 1 and 4, the headphone includes a headband body 11 and two headphone devices 12 provided at both ends of the headband body 11, respectively. The two earphone devices 12 are signal-connected through a wireless communication device. The two earphone devices 12 are connected to the headband body 11 through respective quick-release structures, and adjust the relative positions with respect to the headband body 11.

For example, as shown in fig. 2 and 5, the earphone device 12 includes a housing 17, a power supply 28, a wireless communication device, a speaker 29, a PCB30, and the like. A power supply 28, a wireless communication device, a speaker 29 and a PCB30 are provided within the housing 17. The power supply 28, speaker 29, wireless communication device are connected through PCB 30. The wireless communication device may be, but is not limited to, a bluetooth device or an infrared device, etc. Wireless transmission of audio signals, control signals between the two earphone devices 12 can be achieved by the wireless communication device.

For example, in use, one of the earphone devices 12 acts as a primary earphone and the other as a secondary earphone. The main earphone is connected with external equipment through a wireless communication device to receive audio signals, control signals and the like. The main earphone is connected with the auxiliary earphone through a wireless communication device.

The quick release structure enables quick release and attachment between the headphone assembly 12 and the headband body 11.

In the embodiment of the present disclosure, the two independent earphone devices 12 are connected through the wireless communication device, so that no additional connection wire is required, and the development trend of modularization of the electronic device is complied with.

In addition, the distance between the two earphone devices 12 can be adjusted through the quick release device, so that different users can be accommodated. Since there is no interference of the connecting lines, the maximum distance between the two earphone devices 12 is not limited.

In addition, the quick release structure greatly improves the replaceability of the earphone device 12. The earphone device 12 is easily replaced when a malfunction occurs.

Further, as separate electroacoustic conversion means, the functions of the two headphone devices 12 are the same, which makes the headphone device 12 have good versatility. The two earphone devices 12 are manufactured according to one standard. In use, it is not necessary to distinguish between the kinds of earphone devices 12, such as left and right earphones.

In one example, as shown in fig. 2-3, the quick release structure includes a snap fitting 13 provided on the earphone device 12. The headband body 11 is provided with a plurality of clip grooves 14 which are matched with the clip connectors 13. The clamping connector 13 is clamped with the clamping groove 14.

The quick release structure may further include a plurality of clamping grooves 14 provided on the earphone device 12, and a plurality of clamping connectors 13 matched with the clamping grooves 14 are provided on the headband, wherein the clamping connectors 13 are clamped with the clamping grooves 14.

The snap fitting 13 is inserted into the card slot 14 from the side of the card slot 14. An interference fit or clearance fit is formed between the clamping groove 14 and the clamping connector 13, so that the clamping connector 13 is fixed in position in the clamping groove 14. The clamping joint 13 is clamped with different clamping grooves 14, so that the relative positions of the earphone device 12 and the headband body 11 are adjusted, and the distance between the two earphone devices 12 is further adjusted. This connection facilitates connection and disconnection between the headphone device 12 and the headband body 11.

Furthermore, this connection facilitates replacement of the earphone device 12.

In one example, as shown in FIGS. 2-3, the snap-fit connection 13 is T-shaped in configuration. The cross section of the clamping groove 14 is T-shaped. The clamping structure formed by the clamping connector 13 of the T-shaped structure and the clamping groove 14 of the T-shaped structure has the characteristics of balanced stress and firm structure.

Of course, the specific shapes of the snap fitting 13 and the snap groove 14 are not limited thereto, and those skilled in the art can select them according to actual needs.

In one example, as shown in fig. 3, a plurality of card slots 14 are provided on the headband body 11. The extending direction of the plurality of card slots 14 is perpendicular to the extending direction of the headband body 11. When the engagement is performed, the engagement connector 13 is inserted into the engagement groove 14 from both sides in the width direction of the headband body 11, and the engagement groove 14 is easily switched.

Further, the plurality of card slots 14 are arranged at equal intervals. For example, adjacent card slots 14 are spaced 0.5 cm apart. This makes the distance adjustment between the two earphone arrangements 12 more accurate.

In the above-described manner of connection, the adjustment of the distance between the two earphone devices 12 is discontinuous. The applicability of this adjustment is lower than that of continuous adjustment.

In one example, as shown in FIG. 4, the quick release structure includes a base, a resilient member, and a first handle 19. The base comprises a stem 15 and a stop 16 arranged at a first end of the stem 15. For example, the base may have a T-shaped overall configuration. The housing 17 of the earphone arrangement 12 has a through hole 18. The stop 16 is located within a housing 17. The second end of the stem 15 passes out of the through hole 18. The first handle 19 is pivotally connected to the second end. The elastic element is located between the housing 17 and the stop 16. For example, the elastic element is a spring 20. The spring 20 is sleeved outside the stem 15 and is located between the housing 17 and the stopper 16. The headband body 11 is provided with a chute 21. The second end of the stem 15 passes through the runner 21. The headband body 11 is located between the housing 17 and the first handle 19. The quick release structure can slide along the chute 21. The elastic member forms an elastic force, for example, a pretension, when the fixing is performed, so that the headband body 11 is clamped between the housing 17 and the first handle 19. Friction is generated between the headband body 11 and the housing 17 and the first handle 19, thereby locking the position of the earphone device 12

In this example, when it is desired to adjust the position of the earphone arrangement 12, the user pulls the first handle 19 so that the resilient element, e.g. the spring 20, is compressed. At this time, the force with which the headband body 11 is clamped is reduced, the friction is reduced, and the user pulls the first handle 19 along the chute 21 to move the earphone device 12. When the proper position is reached, the user releases the first handle 19, and the headband body 11 is clamped by the housing 17 and the first handle 19 under the driving of the spring 20, thereby fixing the position of the earphone device 12.

The quick release structure enables continuous adjustment of the position of the earphone device 12. The earphone device 12 can be fixed at any position of the chute 21 as needed.

To facilitate adjusting the position of the earphone device 12, in one example, as shown in fig. 5, the first handle 19 includes a support portion 22, a trigger portion 23, and a pivot point 24 between the support portion 22 and the trigger portion 23. The pivot point 24 is pivotally connected to the second end, for example by a pin. One side in the main body direction of the first handle 19 is an adjustment side 25, and the other side is a lock side 26. When the pulling portion 23 is pulled, the adjusting side 25 and the locking side 26 are defined by the support portion 22. As shown in fig. 7-8, the distance from the end of the meter support 22 to the pivot point 24 is L1, the distance from the housing 17 to the pivot point 24 is L2 when the housing 17 is on the lock side 26, and the distance from the housing 17 to the pivot point 24 is L3 when the housing 17 is on the adjustment side 25, L1 > L2 > L3.

As shown in fig. 8, when adjusting the position of the earphone device 12, the user pulls the moving part so that the housing 17 is located at the adjustment side 25 of the first handle 19. At this time, the distance from the housing 17 to the pivot point 24 is L3. The extent to which the resilient element, e.g. the spring 20, is compressed is minimal, even if the spring 20 is relaxed. The headband body 11 is not completely clamped. The earphone arrangement 12 is in an adjustable state. The user can adjust the position of the earphone device 12 along the chute 21 at will.

After being adjusted in place, as shown in fig. 7, the user pulls the trigger 23, the first handle 19 pivots about the pivot point 24 and moves the support 22 over the housing 17 so that the housing 17 is located on the locking side 26 of the first handle 19. Since L2 > L3, the springs 20 are compressed so that the headband body 11 is clamped by the first handle 19 and the housing 17. At this time, the headphone device 12 is fixed at the set position of the headband body 11, and the headphone device 12 is in a locked state.

Since the distance L1 > L2 from the end of the support 22 to the pivot point 24, the first handle 19 does not automatically pass over the support 22 to unlock the earphone device 12. This makes the fixation of the earphone device 12 more secure.

In this example, the position of the earphone device 12 is easily adjusted by pulling the first handle 19 so that the quick release structure is in an adjustable state, in which the spring 20 is not fully compressed. The quick release mechanism is placed in the locked position by pulling the second handle 19 in opposite directions. The earphone device 12 is fixed. This quick release structure makes the position adjustment and the fixed locking of the earphone device 12 very easy.

In one example, as shown in fig. 5-8, the support 22 projects toward the locking side 26. The connection line between the end of the support portion and the pivot point forms an obtuse angle with the main body direction of the pulling portion 23. The angle can be set according to actual needs. In this example, the side surrounded by the first handle 19 is the locking side 26. The side opposite this side is the adjustment side 25. In this arrangement, the first handle 19 is simple in structure and easy to operate in a quick release configuration.

In other examples (not shown), the thickness of the portion of the first handle 19 located on the fixed side to the pivot point 24 is greater than the thickness of the portion located on the adjustment side 25 to the pivot point 24, in a manner that also enables adjustment of the degree of compression of the spring 20, thereby placing the quick release structure in an adjustable or locked state.

In one example, as shown in fig. 6 and 8, the first handle 19 can rotate about the axis of the stem 15. The axis of the stem 15 refers to the virtual center line of the stem 15 in the axial direction. The thickness D1 of the first handle 19 is less than or equal to the width B2 of the chute 21. This thickness is the dimension of the thickest part of the first handle 19. Thus, when the earphone device 12 is mounted, the first handle 19 can pass through the slide groove 21 in the thickness direction, so that the second end also passes through the slide groove 21. The width B1 of the first handle 19 is greater than the width B2 of the chute 21. The first handle 19 is caught by the headband body 11 in the width direction by rotating the handle 19. This facilitates the disassembly and assembly between the earphone device 12 and the headband body.

The material of the first handle 19 is metal, plastic, wood, etc. The elastic element can also be a spring piece, an elastic rubber piece and the like. The stem 15 is a cylinder, a square column, a polygonal column, or the like. Those skilled in the art can make the selection according to actual needs.

In one example (not shown), the quick release structure comprises a resilient member, a second handle 19 and a post provided on the housing 17 of the earphone device 12. Pivoted to the second handle 19 at the end of the column. The headband body 11 is provided with a chute 21. The quick release structure can slide along the chute 21. The elastic element is located between the second handle 19 and the headband body 11. The elastic member forms an elastic force when the fixing is performed so that the headband body 11 is clamped between the housing 17 and the elastic member.

The elastic element may be located between the housing 17 and the headband body 11, and form an elastic force when the headband body 11 is fastened between the second handle 19 and the elastic element.

The working principle of the quick release structure is similar to that of the quick release structure with the elastic element. In this example, the headband body 11 is clamped between the shell 17 and the elastic element or between the second handle 19 and the elastic element. The quick release structure also enables the fixation of the earphone device 12 and the adjustment of the relative position. The second handle 19 may be provided in the same structure as the first handle 19. The elastic element is as described previously. For example, the elastic element is a spring. The spring is sleeved on the main body.

Of course, the quick release structure may be other structures that enable fixing of the earphone device 12 and adjustment of the relative position. For example, the engagement is performed by a spring engagement ball.

While certain specific embodiments of the invention have been described in detail by way of example, it will be appreciated by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the invention. It will be appreciated by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the invention. The scope of the invention is defined by the appended claims.
