Description

Technical Field

[0001] The present disclosure relates to the technical field of earphone adjustment, and in particular to an ear shell rolling adjustment mechanism and a headphone. Background Art

[0002] Headphones can be divided into head-mounted, back-hanging and in-ear types according to different wearing methods. Among them, head-mounted headphones are worn by clamping the headband on the head, and the ear shell can completely wrap the ear. Compared with other types of headphones, they are more firmly worn and have better sound amplification effects, so they are widely used in life.

[0003] At present, traditional headphones usually use buttons to adjust sound parameters such as volume, sound playback progress, and reception frequency. For example, Chinese patent document CN205726255U discloses a headset including a volume button, a frequency knob, a display screen, a headset cover, a first headset body, a connecting mechanism, and a second headset body connected in sequence; the volume button and the display screen are arranged on the second end face of the second cylinder, and the frequency knob is arranged on the side of the second cylinder.

[0004] However, the design of the above-mentioned earphones still has the following problems:

[0005] The above-mentioned earphones can adjust the sound parameters such as the volume and the radio frequency by pressing the volume button or turning the frequency knob. However, since the volume button is installed on the ear shell of the earphone, when the ear shell wraps the entire ear, it will be difficult for the user to distinguish the position of the volume button "+" and the volume button "-" by eyes, which makes it easy for the user to press the wrong volume button. At the same time, since the frequency knob is set on the side of the ear shell, when the radio frequency needs to be adjusted, the user can only turn the frequency knob by one hand, which makes it easy for the ear shell to be unevenly stressed and deviated, causing inconvenience to the user.

[0023] Compared with the prior art, the present invention has at least the following advantages:

[0034] In order to facilitate the understanding of the present disclosure, the present disclosure will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present disclosure are given in the drawings. However, the present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present disclosure more thoroughly and comprehensively understood.

[0035] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present disclosure. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0037] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0038] like Figure 1 and Figure 2As shown, an ear shell rolling adjustment mechanism 100 of an embodiment includes an ear shell body 110, a speaker assembly 120, an encoder 130, a rolling body 140 and a support plate group 150; the speaker assembly 120 is arranged in the ear shell body 110, and the sound-emitting surface 1210 of the speaker assembly 120 is embedded on the ear-adjacent side 1110 of the ear shell body 110, and the ear-adjacent side 1110 of the ear shell body 110 is used to fit the human ear; the support plate group 150 is arranged at the edge of the speaker assembly 120 and is perpendicular to the sound-emitting surface 1210 of the speaker assembly 120. ; A toggle opening 1120 is opened on the ear shell body 110, and the toggle opening 1120 is arranged opposite to the support plate group 150; the encoder 130 is arranged on the support plate group 150 and is electrically connected to the speaker assembly 120; the rolling body 140 is rollingly arranged in the toggle opening 1120, the first end of the rolling body 140 is connected to the sensing end of the encoder 130, and the second end of the rolling body 140 is rotatably connected to the support plate group 150, and the rolling axis O of the rolling body 140 is parallel to the support plate group 150 and the sound-emitting surface 1210 of the speaker assembly 120.

[0039] It can be understood that compared with the earphones in the prior art, the above-mentioned ear shell rolling adjustment mechanism 100 has a support plate group 150 that is perpendicular to the sound-emitting surface 1210 of the speaker assembly 120, and the dial port 1120 on the ear shell body 110 is arranged opposite to the support plate group 150. By making the rolling body 140 roll at the dial port 1120, and making the rolling axis O of the rolling body 140 parallel to the support plate group 150 and the sound-emitting surface 1210 of the speaker assembly 120 respectively, when the rolling body 140 is rotated, the force on the rolling body 140 remains perpendicular to the sound-emitting surface 1210 of the speaker assembly 120. Because the sound-emitting surface 1210 of the speaker assembly 120 is embedded on the ear-contacting side 1110 of the ear shell body 110, when the ear-contacting side 1110 of the ear shell body 110 is in contact with the human ear, the sound-emitting surface 1210 of the speaker assembly 120 can also be attached to the human ear, and then the force of the rolling body 140 can be borne and offset by the human ear, thereby balancing the force of the entire ear shell rolling adjustment mechanism 100, and ultimately reducing the occurrence of overall deviation of the ear shell rolling adjustment mechanism 100 when operated with one hand.

[0040] It can be understood that when the rolling body 140 is rolled and arranged at the dialing mouth 1120, by connecting the first end of the rolling body 140 to the sensing end of the encoder 130 and rotating the second end of the rolling body 140 to the support plate group 150, the rolling body 140 can be tightly accommodated in the dialing mouth 1120, which can not only prevent the rolling body 140 from being dislodged from the dialing mouth 1120 due to excessive force applied by the user, but also enable the rolling body 140 to roll smoothly in the dialing mouth 1120, thereby triggering the encoder 130 to change the sound state of the speaker assembly 120. Compared with the earphones in the prior art, the ear shell rolling adjustment mechanism 100 only needs to rotate the rolling body 140 clockwise or counterclockwise around the rolling axis O to adjust the sound state of the speaker assembly 120, such as adjusting the volume of the earphone, thereby avoiding the situation where the user presses the wrong volume button, and is more convenient for users to use.

[0041] It should be noted that the electrical connection may be a wired connection or a wireless connection, the wired connection may be a wire connection, a circuit board connection, etc., and the wireless connection may be a Bluetooth connection, a Wi-Fi connection, etc. Of course, this is not limited here, and those skilled in the art may also make other choices as needed.

[0042] Combination Figure 3 As shown, in this embodiment, the support plate group 150 includes a bracket 1510, a central control circuit board 1520 and a hanging arm 1530; the bracket 1510 is connected to the speaker assembly 120; the central control circuit board 1520 is arranged on the bracket 1510 and is perpendicular to the sound-emitting surface 1210 of the speaker assembly 120; the hanging arm 1530 and the encoder 130 are respectively arranged at opposite ends of the central control circuit board 1520, and the encoder 130 is electrically connected to the central control circuit board 1520. The central control circuit board 1520 is electrically connected to the speaker assembly 120; the rolling body 140 is arranged between the hanging arm 1530 and the encoder 130, and a bayonet 1531 is opened on the hanging arm 1530. The first end of the rolling body 140 is connected to the sensing end of the encoder 130, and the second end of the rolling body 140 is rotatably inserted into the bayonet 1531. The bayonet 1531, the rolling body 140 and the sensing end of the encoder 130 are coaxially arranged on the rolling axis O of the rolling body 140.

[0043] It can be understood that because the central control circuit board 1520 is perpendicular to the sound-emitting surface 1210 of the speaker assembly 120, by coaxially arranging the bayonet 1531, the rolling body 140 and the sensing end of the encoder 130 on the rolling axis O of the rolling body 140, the force that drives the rolling body 140 to rotate is perpendicular to the sound-emitting surface 1210 of the speaker assembly 120. At the same time, because the hanging arm 1530 and the encoder 130 are respectively arranged at the opposite ends of the central control circuit board 1520, when the rolling body 140 is arranged between the hanging arm 1530 and the encoder 130, by connecting the first end of the rolling body 140 to the sensing end of the encoder 130, and rotating the second end of the rolling body 140 to pass through the bayonet 1531, the forces at both ends of the rolling body 140 are balanced and firmly fixed on the central control circuit board 1520 when the rolling body 140 is turned. The rolling body 140 is less likely to be displaced when turned, and the rotation force of the rolling body 140 can more stably maintain a state perpendicular to the sound-emitting surface 1210 of the speaker assembly 120.

[0044] It can be understood that because the encoder 130 is electrically connected to the central control circuit board 1520, the central control circuit board 1520 is electrically connected to the speaker assembly 120, and the first end of the rolling body 140 is connected to the sensing end of the encoder 130, when the rolling body 140 is rotated by being turned, the first end of the rolling body 140 rotates and triggers the sensing end of the encoder 130, triggering the encoder 130 to sense the rotation angle of the rolling body 140 and adjust the sound parameters such as the volume or the radio frequency of the speaker assembly 120 through the central control circuit board 1520, thereby quickly adjusting the sound state of the speaker assembly 120.

[0045] Combination Figure 4As shown, further, a slide groove 1521 is opened on the central control circuit board 1520, and a pressing handle 1532 is protruded on one side of the hanging arm 1530; the hanging arm 1530 is slidably set in the slide groove 1521 and is clamped on the groove wall of the slide groove 1521; a sliding gap 1533 is formed between the pressing handle 1532 and the central control circuit board 1520, and a micro switch 1540 is arranged in the sliding gap 1533, and the base 1541 of the micro switch 1540 is fixed and electrically connected to the central control circuit board 1520, and the pressing part 1542 of the micro switch 1540 abuts against the pressing handle 1532. It can be understood that by setting a sliding gap 1533 between the pressing handle 1532 and the central control circuit board 1520, by making the hanging arm 1530 slide in the slide groove 1521 and snap-fitted to the groove wall of the slide groove 1521, when the user turns the rolling body 140, the rolling body 140 can drive the hanging arm 1530 to slide along the slide groove 1521, thereby changing the size of the sliding gap 1533. Because the micro switch 1540 is set in the sliding gap 1533, the pressing part 1542 of the micro switch 1540 abuts against the pressing handle 1532. When the sliding gap 1533 is reduced, the pressing handle 1532 will press down to trigger the micro switch. The pressing part 1542 of the switch 1540, because the base 1541 of the micro switch 1540 is fixed and electrically connected to the central control circuit board 1520, and the central control circuit board 1520 is electrically connected to the speaker assembly 120, the micro switch 1540 can adjust the sound parameters such as the volume or the radio frequency of the speaker assembly 120 through the central control circuit board 1520, so that the encoder 130 and the micro switch 1540 can be triggered at the same time by turning the rolling body 140, so that the above-mentioned ear shell rolling adjustment mechanism 100 can adjust two different sound parameters of the speaker assembly 120 at the same time, and the function is more integrated and more convenient to use. Among them, the sound parameters are not limited to the volume or the radio frequency, etc., which are not limited here.

[0046] Combination Figure 4 and Figure 5As shown, specifically, the slide groove 1521 is a through groove; a hook 1534 is provided at one end of the hanging arm 1530; the hook 1534 includes a sliding portion 153a and a hook portion 153b, the sliding portion 153a is slidably arranged in the slide groove 1521, and one end of the sliding portion 153a is connected to the hanging arm 1530; the hook portion 153b is protruded from the other end of the sliding portion 153a and is supported by the notch of the slide groove 1521. It can be understood that because one end of the sliding portion 153a is connected to the hanging arm 1530, when the user moves the rolling body 140, the hanging arm 1530 is driven by the rolling body 140 to push the hook 1534 to move. Because the sliding portion 153a slides through the sliding groove 1521, the pressing handle 1532 can move along the sliding groove 1521 to compress the sliding gap 1533. The pressing handle 1532 presses down to trigger the pressing portion 1542 of the micro switch 1540. When the user has finished moving the rolling body 140, the pressing portion 1542 of the micro switch 1540 will be reset and push up the pressing handle 1532, so that the sliding portion 153a will be reset along the sliding groove 1521. Because the other end of the sliding portion 153a is convexly provided with a hook portion 153b, the hook portion 153b will be pressed against the notch of the sliding groove 1521 after the sliding portion 153a is reset, thereby preventing the hook 1534 from falling out of the sliding groove 1521.

[0047] Combination Figure 3 and Figure 4 As shown, in this embodiment, a protective sleeve 1550 is sleeved on the second end of the rolling body 140, the inner wall of the protective sleeve 1550 is slidably connected to the second end of the rolling body 140, and the outer wall of the protective sleeve 1550 is clamped in the bayonet 1531. It can be understood that by sleeved on the second end of the rolling body 140, because the second end of the rolling body 140 is slidably connected to the inner wall of the protective sleeve 1550, and the outer wall of the protective sleeve 1550 is clamped in the bayonet 1531, when the rolling body 140 is moved, the second end of the rolling body 140 can smoothly rotate in the protective sleeve 1550, so as to avoid the second end of the rolling body 140 from directly contacting with the bayonet 1531 and being worn.

[0048] Combination Figure 3As shown, in one embodiment, the bracket 1510 includes two embedded arms 1511 arranged at intervals, each embedded arm 1511 is perpendicular to the sound-emitting surface 1210 of the speaker assembly 120, and each embedded arm 1511 is respectively provided with a guide groove 151a in the length direction; the central control circuit board 1520 is arranged between the two embedded arms 1511, and the two ends of the central control circuit board 1520 are respectively slidably arranged in the corresponding guide grooves 151a. It can be understood that by making the embedded arms 1511 perpendicular to the sound-emitting surface 1210 of the speaker assembly 120, and making the guide groove 151a open along each embedded arm 1511 in the length direction, when the two ends of the central control circuit board 1520 are respectively installed on the bracket 1510 along the corresponding guide groove 151a, the central control circuit board 1520 will be perpendicular to the sound-emitting surface 1210 of the speaker assembly 120 under the guidance of the guide groove 151a. When the central control circuit board 1520 needs to be removed, the user can quickly remove it by pulling out the two ends of the central control circuit board 1520 along the corresponding guide groove 151a.

[0049] Combination Figure 4 As shown, in one embodiment, the encoder 130 is a magnetic encoder, and the first end of the rolling body 140 is passed through and clamped to the inner rotor 1310 of the encoder 130. It can be understood that because the encoder 130 is a magnetic encoder, by making the first end of the rolling body 140 pass through and clamped to the inner rotor 1310 of the encoder 130, when the rolling body 140 rotates, the first end of the rolling body 140 can synchronously drive the inner rotor 1310 of the encoder 130 to rotate to generate a magnetic field change, thereby enabling the encoder 130 to accurately sense the rotation angle of the rolling body 140, and finally more accurately adjust the sound state of the above-mentioned ear shell rolling adjustment mechanism 100.

[0050] It should be particularly noted that the method of controlling the speaker assembly 120 or the central control circuit board 1520 through the encoder 130, the method of controlling the speaker assembly 120 through the central control circuit board 1520, and the method of sensing the rotation angle of the rolling body 140 through the encoder 130 are all prior arts and are not within the scope of protection of the present disclosure. The present disclosure only protects the components of the ear shell rolling adjustment mechanism 100 of this embodiment and their positions and connection relationships.

[0051] Combination Figure 2 and Figure 3As shown, in this embodiment, the rolling body 140 includes a first shaft 1410, a capsule-shaped roller 1420 and a second shaft 1430 connected in sequence; the first shaft 1410 and the second shaft 1430 are respectively arranged at opposite ends of the capsule-shaped roller 1420; the capsule-shaped roller 1420 is arranged in the dialing port 1120 and slidably abuts against the inner wall of the dialing port 1120; the first shaft 1410 is connected to the sensing end of the encoder 130, and the second shaft 1430 is rotatably connected to the support plate group 150. It can be understood that by arranging the capsule-shaped roller 1420 in the dialing port 1120, because the capsule-shaped roller 1420 slidably abuts against the inner wall of the dialing port 1120, the surface of the capsule-shaped roller 1420 is smooth and flat, so that the user can dial the capsule-shaped roller 1420 more smoothly. At the same time, the first shaft 1410 is connected to the sensing end of the encoder 130, and the second shaft 1430 is rotatably connected to the support plate group 150, so that the capsule-shaped roller 1420 can be tightly connected to the encoder 130 and the support plate group 150, and is less likely to deflect or slip out of the dialing mouth 1120 when the user dials it.

[0052] Combination Figure 1 As shown, in this embodiment, the ear shell rolling adjustment mechanism 100 further includes a cushion ear ring 160; the cushion ear ring 160 is arranged on the ear-contacting side 1110 of the ear shell body 110, and abuts and seals against the edge of the sound-emitting surface 1210 of the speaker assembly 120. It can be understood that by arranging the cushion ear ring 160 on the ear-contacting side 1110 of the ear shell body 110, when the user wears the above-mentioned ear shell rolling adjustment mechanism 100, the cushion ear ring 160 can be pressed against the human ear, and the force generated by moving the rolling body 140 will act on the cushion ear ring 160 and offset it more quickly, thereby reducing the force of the sound-emitting surface 1210 of the speaker assembly 120 on the human ear, making the user more comfortable to wear. At the same time, by making the cushion ear ring 160 abut against the edge of the sound-emitting surface 1210 of the sealed speaker assembly 120, the sound leakage emitted by the sound-emitting surface 1210 of the speaker assembly 120 is reduced, thereby improving the sound insulation effect of the above-mentioned ear shell rolling adjustment mechanism 100.

[0053] like Figure 6As shown, the present disclosure further provides a headset 10, comprising a headband 200 and two ear shell rolling adjustment mechanisms 100 of any of the above-mentioned embodiments; the two ear shell rolling adjustment mechanisms 100 are respectively arranged at both ends of the headband 200, and the headband 200 is used to be clamped on the head; the ear-contacting sides 1110 of the ear shell main bodies 110 of the two ear shell rolling adjustment mechanisms 100 are relatively arranged and respectively fit the corresponding human ears. It can be understood that by making the headband 200 be clamped on the human head and making the ear-contacting side 1110 of the ear shell main body 110 of the ear shell rolling adjustment mechanism 100 correspond to the human ear, the above-mentioned headphone 10 can be worn securely. When the user pushes the rolling body 140 of the ear shell rolling adjustment mechanism 100 on one side of the human head inward, the force of the rolling body 140 can be borne and offset by the corresponding human ear. When the user pushes the rolling body 140 of the ear shell rolling adjustment mechanism 100 on one side of the human head outward, because the headband and the other ear shell rolling adjustment mechanism 100 are jointly in contact with the human head, the force of the rolling body 140 can also be offset, so that the ear shell rolling adjustment mechanism 100 always maintains balance when adjusting the sound parameters, and finally reduces the occurrence of overall deviation of the headphone 10 when operated with one hand.

[0054] Compared with the prior art, the present invention has at least the following advantages:

[0055] 1) Compared with the earphones in the prior art, the ear shell rolling adjustment mechanism 100 has a support plate group 150 that is perpendicular to the sound-emitting surface 1210 of the speaker assembly 120, and a dial opening 1120 on the ear shell body 110 is arranged opposite to the support plate group 150. By making the rolling body 140 roll at the dial opening 1120, and making the rolling axis O of the rolling body 140 parallel to the support plate group 150 and the sound-emitting surface 1210 of the speaker assembly 120 respectively, when the rolling body 140 is rotated, the force on the rolling body 140 remains perpendicular to the sound-emitting surface 1210 of the speaker assembly 120. Because the sound-emitting surface 1210 of the speaker assembly 120 is embedded on the ear-contacting side 1110 of the ear shell body 110, when the ear-contacting side 1110 of the ear shell body 110 is in contact with the human ear, the sound-emitting surface 1210 of the speaker assembly 120 can also be attached to the human ear, and then the force of the rolling body 140 can be borne and offset by the human ear, thereby balancing the force of the entire ear shell rolling adjustment mechanism 100, and ultimately reducing the occurrence of overall deviation of the ear shell rolling adjustment mechanism 100 when operated with one hand.

[0056] 2) When the rolling body 140 is rolled and arranged at the dialing mouth 1120, by connecting the first end of the rolling body 140 to the sensing end of the encoder 130 and rotating the second end of the rolling body 140 to the support plate group 150, the rolling body 140 can be tightly accommodated in the dialing mouth 1120, which can not only prevent the rolling body 140 from being dislodged from the dialing mouth 1120 due to excessive force applied by the user, but also enable the rolling body 140 to roll smoothly in the dialing mouth 1120, thereby triggering the encoder 130 to change the sound state of the speaker assembly 120. Compared with the earphones in the prior art, the above-mentioned ear shell rolling adjustment mechanism 100 only needs to make the rolling body 140 rotate clockwise or counterclockwise around the rolling axis O to adjust the sound state of the speaker assembly 120, such as adjusting the volume of the earphone, thereby avoiding the situation where the user presses the wrong volume button, and is more convenient for users to use.

[0057] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be based on the attached claims.
