Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic equipment, and in particular to an immersive earphone. BACKGROUND

[0002] The immersive earphone is favored by users because it has a noise reduction function and can switch between transmission and noise reduction functions. The immersive earphone in the prior art is roughly divided into two types: one is to control the opening and closing of the noise reduction function by identifying the key sound of the external environment, and the second is to switch between transmission and noise reduction functions by flipping, replacing the sound insulation shell, and opening or blocking the sound hole with earplugs.

[0003] However, the first type of earphone described above causes users to be unable to switch between transmission and noise reduction functions autonomously, and there are problems with voice recognition accuracy. The second type of earphone described above causes users to be too cumbersome in switching between transmission and noise reduction functions, and the user experience is not good.

[0004] In addition, the two types of earphones described above only have a switchable noise reduction function, i.e., they can only switch between the two extreme functions of transmission and noise reduction, and cannot adjust the degree of noise reduction.

DETAILED DESCRIPTION

[0040] In order to make the technical solution of the present application better understood by those skilled in the art, the present application will be described in detail below in combination with the drawings and specific embodiments.

[0041] As shown in the drawings, the embodiment of the present application discloses an immersive earphone 100 which is assembled in pairs by arc-shaped elastic members 200 so that both sides of the user's ears are worn at the same time. Each immersive earphone 100 comprises a first component 10, a second component 20 and a speaker 30. Figures 1 to 6 As shown in the drawings, the first component 10 and the second component 20 cooperate to jointly define a sound passage hole 40 leading to the speaker 30, which functions to allow external environmental sound to enter the user's ear. If the cross section of the sound passage hole 40 is increased, the proportion of external environmental sound entering the user's ear will increase (the proportion of internal environmental sound emitted by the speaker 30 will decrease), until reaching a completely transparent state. If the cross section of the sound passage hole 40 is reduced, the proportion of external environmental sound entering the user's ear will decrease (the proportion of internal environmental sound emitted by the speaker 30 will increase), until reaching a completely noise reduction state.

[0042] Figure 2 The first component 10 and the second component 20 can define the sound passage hole 40 through various structures and cooperation, for example, the first component 10 and the second component 20 define the sound passage hole 40 through two parallel and opposite planes (not shown in the drawings), at this time the sound passage hole 40 can be regarded as a sound passage gap, by changing the gap between the first component 10 and the second component 20 to change the distance between the two planes, and then change the sound passage gap.

[0043] In some preferred embodiments, as shown in the drawings, the first component 10 and the second component 20 are connected by a sound insulation ring 50, which is a hollow ring with a sound passage hole 40 in the center. The sound passage hole 40 is connected to the speaker 30, and the sound insulation ring 50 is connected to the first component 10 and the second component 20 through a telescopic rod 63 and a retaining member 64.

[0044] In some preferred embodiments, as shown in the drawings, the first component 10 and the second component 20 are connected by a sound insulation ring 50, which is a hollow ring with a sound passage hole 40 in the center. The sound passage hole 40 is connected to the speaker 30, and the sound insulation ring 50 is connected to the first component 10 and the second component 20 through a telescopic rod 63 and a retaining member 64. Figures 2 to 4 ​As shown, the sound hole 40 is defined by a mating conical bore surface 11 and a conical cylindrical surface 21. Specifically, the conical bore surface 11 is formed at the center of the first component 10, and the conical cylindrical surface 21 is formed on the outer peripheral surface of the second component 20. The first component 10 is fitted over the second component 20, and the gap between the conical bore surface 11 and the conical cylindrical surface 21 forms the sound hole 40. Thus, by moving the first component 10 and the second component 20 axially relative to each other, the gap between the conical bore and the conical cylindrical surface 21 is adjusted, thereby adjusting the cross-section of the sound hole 40.

[0045] In this invention, the first component 10 and the second component 20 are axially moved relative to the first component 10 by means of an adjustment mechanism constructed between them.

[0046] In some preferred embodiments of the present invention, two types of adjustment mechanisms are provided.

[0047] First type of regulating mechanism:

[0048] like Figure 2 As shown, this adjustment mechanism is a threaded engagement mechanism 70 constructed between the first component 10 and the second component 20. Specifically, a threaded hole 71 is opened on the inner side of the center of the first component 10, and a stud with an external thread 72 is formed on the inner side of the second component 20. The stud extends into the threaded hole 71, allowing the first component 10 to rotate only and the second component 20 to move only axially. For example, the axial movement of the first component 10 can be restricted by a limiting structure, allowing only rotation, and the rotation of the second component 20 can be restricted by a guide post, allowing only axial movement. Thus, when the first component 10 is rotated, the second component 20 moves axially relative to the first component 10 through the engagement of the threaded hole 71 and the stud, thereby adjusting the cross-section of the sound hole 40 defined by the conical hole surface 11 and the conical cylinder surface 21, thereby adjusting the volume of the external environment entering the human ear to change the ratio of internal ambient sound to external ambient sound.

[0049] Based on the above description, when a user wants to adjust the level of immersion, for example, when a user wants to increase the external ambient sound, the first component 10 can be manually turned to increase the cross-section of the sound hole 40; when a user wants to increase the internal ambient sound, the first component 10 can be manually turned in the opposite direction to decrease the cross-section of the sound hole 40.

[0050] The second type of regulating mechanism:

[0051] like Figure 3 and Figure 4As shown, the adjusting mechanism is an electric driving mechanism constructed between the first part 10 and the second part 20, which is used to drive the second part 20 to move axially relative to the first part 10, thereby changing the cross section of the sound hole 40. Specifically, the adjusting mechanism comprises a retaining member 64, a motor 61, and a telescopic rod 63. The retaining member 64 is formed on the inner side of the second part 20; the motor 61 is installed on the second part 20, and a positioning shell 68 is formed at the output end of the motor 61, which has a guide hole facing the retaining member 64; the telescopic rod 63 is arranged in the guide hole of the positioning shell 68; the output shaft of the motor 61 is provided with a gear, which is engaged with the teeth formed on the outer side of the telescopic rod 63 to drive the telescopic rod 63 to extend or retract in the guide hole, so as to push the retaining member 64 to make the second part 20 move axially to change the cross section of the sound hole 40.

[0052] The above-mentioned electric driving mechanism is controlled by a control assembly. Specifically, the control assembly comprises a control switch 69 installed on the outside of the earphone body (for example, at the root of the arc-shaped elastic member 200) and a control module 62 installed inside the earphone body (for example, inside the second part 20). By operating the control switch 69, for example, pressing the control switch 69, pushing the control switch 69, etc., the control module 62 sends an electric signal to the motor 61, and finally controls the motor 61 to move the second part 20 axially.

[0053] In some preferred embodiments, a sliding resistance adjusting mechanism 65 is also connected in the above-mentioned adjusting mechanism, and the control module 62 can change the electric signal to control the motor 61 and the loudspeaker 30 through the sliding resistance adjusting mechanism 65. Specifically, the first part 10 is arranged in a split structure, i.e., the first part 10 comprises a main body part 12 with a cylindrical surface and a screw ring 13 sleeved outside the main body part 12, which can rotate relative to the main body part 12. The sliding resistance adjusting mechanism 65 is arranged between the screw ring 13 and the main body part 12, for example, a contact is arranged on the inner wall of the screw ring 13, and a resistance strip is arranged on the outer periphery of the main body part 12. By rotating the screw ring 13, the position of the contact on the resistance strip can be changed, thereby changing the size of the connected resistance, and different resistances will produce different electric signals. The control module 62 connected with the sliding resistance adjusting mechanism 65 controls the motor 61 and the loudspeaker 30 based on the electric signal changed by the sliding resistance adjusting mechanism 65. The specific configuration is as follows:

[0054] When the rotating ring 13 is rotated in one direction, the resistance connected to the sliding rheostat mechanism 65 decreases (or increases), and the control module 62 controls the motor 61 to drive the second component 20 to reduce the cross-section of the sound hole 40. The control module 62 then controls the speaker 30 to increase the volume of the internal environment. When the rotating ring 13 is rotated in the opposite direction, the resistance connected to the sliding rheostat mechanism 65 increases (or decreases), and the control module 62 controls the motor 61 to drive the second component 20 to increase the cross-section of the sound hole 40. The control module 62 then controls the speaker 30 to decrease the volume of the internal environment.

[0055] Thus, when noise reduction is needed, rotating the knob 13 will decrease the volume of external ambient sound entering the ear, while increasing the volume of internal ambient sound entering the ear. When pass-through is needed, rotating the knob 13 in the opposite direction will increase the volume of external ambient sound entering the ear, while decreasing the volume of internal ambient sound entering the ear.

[0056] like Figure 5 and Figure 6 and combined Figure 3 and Figure 4 As shown, in some preferred embodiments, the speaker 30 and the control module 62 are connected by an electrical connection part; the electrical connection part includes a conductive sleeve and a conductive post 66 passing through the sleeve; the control module 62 is electrically connected to the outside of the conductive sleeve by a wire, and the end of the conductive post 66 is in contact with the contact point of the speaker 30 to make the control module 62 electrically connected to the speaker 30.

[0057] In some preferred embodiments, such as Figures 2 to 4 As shown, sound-absorbing rings 50 are provided on the conical cylindrical surface 21 and / or the conical hole surface 11. For example, there are two sound-absorbing rings 50; both sound-absorbing rings 50 are provided on the conical cylindrical surface 21; both sound-absorbing rings 50 are made of sound-absorbing cotton; the thickness of the inner sound-absorbing ring 50 is greater than the thickness of the outer sound-absorbing surface. The two sound-absorbing rings 50 with different thicknesses can effectively block external ambient noise from entering the human ear through the sound hole 40, thereby allowing the headphones to switch to a fully noise-canceling state.

[0058] In some preferred embodiments, a display module 67 is also mounted on the surface of the outer side of the second component 20, which can be used to display the state of the earphone, and can provide a prompt according to the state of the earphone. For example, when the earphone is in a full noise reduction state, the display module 67 provides the prompt "inhear". When the earphone is in a full transmission state, the display module 67 provides the prompt "hear". When the earphone is in an intermediate state of noise reduction and transmission, the display module 67 provides the prompt "faintly hear". In this way, the state of the earphone (immersive state) is associated with the display module 67, and in different states, the state of the user is informed to the surrounding people through the display module 67 of the earphone, so that the communication is smoother, and the misunderstanding caused by the user not responding during the surrounding people talking to the user is avoided, and the surrounding people pause speaking and delay communication because they think the user cannot hear.

[0059] The immersive earphone 100 provided by the present application has the following advantages:

[0060] 1. The immersive earphone 100 provided by the present application can be actively adjusted by the user according to needs.

[0061] 2. The immersive earphone 100 provided by the present application can be steplessly adjusted by the user.

[0062] 3. The present application provides two kinds of adjustment modes (manual active adjustment and electric active adjustment) of the immersive earphone 100.

[0063] 4. The display module 67 displays the immersive state and the prompt, so that the user and the surrounding people establish effective communication.
