Description

Technical Field

[0001] The present application relates to the field of earphone technology, and in particular to a multifunctional bone conduction earphone and a method of using the same. Background Art

[0002] At present, bone conduction is a sound conduction method that converts sound into mechanical vibrations of different frequencies and transmits sound waves through the human skull, bony labyrinth, inner ear lymph, spiral organ, and auditory center. Compared with the classic sound conduction method that generates sound waves through the diaphragm, bone conduction saves many steps in sound wave transmission and can achieve clear sound restoration in a noisy environment. Moreover, the sound waves will not affect others because they spread in the air.

[0003] The existing, general bone conduction headphones include an ear hook connection frame and a bone conduction vibrator. There are two bone conduction vibrators, which are respectively installed at the two ends of the ear hook connection frame. When worn, the ear hook connection frame forms a clamping force to make the transmission surface of the bone conduction vibrator fit the surface of the temple cartilage. At this time, the ear hook connection frame fits the back of the head. When the bone conduction headphones are working, you can listen to music through the transmission surface of the bone conduction vibrator. In actual situations, bone conduction headphones are not very suitable in noisy environments, and the user experience is poor, especially when enjoying wonderful music. The interference of noise often makes people feel unhappy, and even makes people more irritable. Noise refers to a sound with chaotic pitch and intensity changes and sounds disharmonious. It is caused by irregular vibrations of the sound-producing body (different from "musical sound").

[0004] With respect to the above-mentioned related technologies, the inventor believes that there is a defect that bone conduction headphones have a poor user experience in noisy environments. Summary of the invention

[0005] In order to facilitate users to enjoy wonderful music in a noisy environment and thus improve user experience, the present application provides a multifunctional bone conduction headset and a method of using the same.

[0006] In a first aspect, the present application provides a multifunctional bone conduction headset using the following technical solution:

[0007] A multifunctional bone conduction headset comprises an ear hook connection frame and a bone conduction vibrator, wherein the bone conduction vibrator is mounted on the ear hook connection frame for transmitting music, and the transmission surface of the bone conduction vibrator is attached to the cartilage in front of the auricle. The present invention is characterized in that: the bone conduction vibrator is rotatably connected to a rotating device, and a noise reduction earphone head adapted to the inner wall of the user's auricle is rotatably connected to the rotating device, and the noise reduction earphone head is electrically connected to the ear hook connection frame and used for playing music, and the ear hook connection frame is electrically connected to a control device, and the control device is used to switch the working states of the noise reduction earphone head and the bone conduction vibrator.

[0008] By adopting the above technical solution, when noise reduction is needed, the noise reduction earphone head is rotated to the inside of the auricle. At the same time, the control device controls the noise reduction earphone head to work and makes the bone conduction vibrator not work. Since the music sound played by the noise reduction earphone head is directly aimed at the ear, it is very convenient for the user to listen to the music sound and avoid noise interference. In addition, when noise reduction is not needed, the noise reduction earphone head is directly turned away from the auricle. At this time, the music can be listened to only through the bone conduction earphone. In this way, the noise reduction effect can be achieved very conveniently, and at the same time, the user's sense of use can be indirectly improved.

[0010] By adopting the above technical solution, when the knob part rotates on the bone conduction vibrator, it can indirectly drive the position of the noise reduction earphone head to move, so that the user can adjust the position of the bone conduction vibrator and improve the applicability of the bone conduction earphone. At the same time, when the noise reduction earphone head rotates on the rotating part, the angle and position of the noise reduction earphone head can be easily adjusted according to actual needs, so that the noise reduction earphone head can be more suitable for the user's auricle.

[0015] Preferably, the noise reduction earphone headphone reduces noise through ENC, and microphones are provided in the shell and the ear hook connecting frame.

[0016] By adopting the above technical solution, ENC (Environmental Noise Cancellation) can effectively suppress 90% of the reverse environmental noise, thereby reducing the environmental noise by up to 35dB, allowing users to communicate more freely. When there are multiple microphones, the direction of the caller's speech can be accurately calculated, while protecting the target voice in the main direction, removing various interference noises in the environment.

[0018] By adopting the above technical solution, the control device can conveniently control the bone conduction vibrator and the noise reduction earphone to transmit or release music sound, and at the same time, it is also convenient to control the volume of the music. The setting of the ear hook body makes it easier for the transmission surface of the bone conduction vibrator to fit in the appropriate position, thereby facilitating the bone conduction vibrator to transmit sound.

[0019] Preferably, a locking rod is provided on the knob portion, and an end of the locking rod is threadedly connected to the positioning portion through the knob portion.

[0020] By adopting the above technical solution, the locking rod can further stabilize the stable rotation of the knob part, and can prevent the knob part from accidentally deviating from the position due to external force.

[0022] By adopting the above technical solution, the clip-fitting mode of the convex edge and the rib groove can further stabilize the position of the knob block, and at the same time, it is also convenient to stably rotate the knob block, further improving the stability during rotation.

[0023] Preferably, the clamping portion is a circular ring block, the circular ring block is mounted on a knob block, and the knob block is made of elastic material.

In this way, it is very convenient to drive the support frame to rotate, and further facilitate the rotation of the noise reduction earphone head.

[0025] In the second aspect, the present application provides a method of use, which adopts the following technical solution:

[0026] A method of use includes: obtaining a switch signal, and judging whether a working circuit of a noise reduction earphone head is turned on based on the switch signal; if the working circuit of the noise reduction earphone head is turned on, outputting a control signal to make the noise reduction earphone head play music, and simultaneously outputting a pause signal to make a bone conduction vibrator stop working; if the working circuit of the noise reduction earphone head is not turned on, the noise reduction earphone head does not work.

[0027] By adopting the above technical solution, the working state of the noise reduction earphone head and the bone conduction vibrator can be conveniently controlled through the switch signal. This control method is simple and easy to implement.

[0028] In summary, the present application includes at least one of the following beneficial technical effects of a multifunctional bone conduction headset and a method of using the same:

DETAILED DESCRIPTION

[0043] The following is combined with Figure 1-11 This application is described in further detail.

[0044] Embodiment 1:

[0045] The present application discloses a multifunctional bone conduction earphone, which can make the bone conduction vibrator 2 and the noise reduction earphone head 3 work alone. When noise reduction is needed, the noise reduction earphone head 3 can be worn to achieve noise reduction. Figure 1It includes a noise reduction headphone head 3, an ear hook connection frame 1 and a bone conduction vibrator 2. Two bone conduction vibrators 2 are provided, which are respectively installed at the two ends of the ear hook connection frame 1. In actual situations, the ear hook connection frame 1 relies on its own clamping force to make the transmission surface of the bone conduction vibrator 2 fit the front cartilage of the auricle. The noise reduction headphone head 3 is rotatably connected to the bone conduction vibrator 2. In this embodiment, the noise reduction headphone head 3 is an in-ear noise reduction headphone head 3. Figure 2 The noise reduction earphone head 3 can also be a flat-ear type noise reduction earphone head 3.

[0046] Reference Figure 3 The ear hook connecting frame 1 includes a control device 4 and an ear hook body. The ear hook connecting frame 1 is U-shaped as a whole and is made of elastic material, specifically composite rubber or silicone. In order to facilitate the user to wear, an ear hook connecting frame 1 is provided on the ear hook connecting frame 1, which is integrally connected to the ear hook connecting frame 1. The ear hook 11 is used to hang on the user's ear to further stabilize the position of the ear hook connecting frame 1 and reduce the burden on the ear hook connecting frame 1.

[0047] Reference Figure 4 The control device 4 includes a control box 41, a control switch 42, a controller 43 and a music playing module 44. Figure 3 , the control box 41 is installed on the ear hook body, the music playing module 44 and the controller 43 are installed in the control box 41, the music playing module 44 is electrically connected to the bone conduction vibrator 2 and the noise reduction earphone head 3, and the music playing module 44 is used for the bone conduction vibrator 2 to transmit music sound, and for the noise reduction earphone head 3 to play music. The control switch 42 is coupled to the music playing module 44, and is used to connect the working circuit where the noise reduction earphone head 3 or the bone conduction vibrator 2 is located, so that the noise reduction earphone head 3 or the bone conduction vibrator 2 works. The control switch 42 includes a single-pole double-throw analog switch with a model number of TS3A44159PWR. When the control switch 42 is turned on, the control switch 42 outputs a switch signal to the controller 43, and the controller 43 includes a main control chip with a model number of ATS3015. After receiving the switch signal, the main control chip outputs a conduction signal to the working input end of the noise reduction earphone head 3. At this time, the working circuit where the noise reduction earphone head 3 is located is turned on, and music starts to play.

[0048] Reference Figure 4 The control box 41 is also equipped with an active noise reduction ENC circuit 47 and a charging module 46. The active noise reduction ENC circuit 47 can effectively suppress 90% of the reverse environmental noise, allowing the user to communicate more freely. In order to further improve the noise reduction effect, refer to Figure 3The control box 41 and the noise reduction headphone head 3 are provided with an environmental microphone 45 and a call microphone 33 respectively. The environmental microphone 45 can collect the environmental sounds from the side and rear of the user, and can separate the user's voice content by comparing it with the sound signal received by the front call microphone 33, thereby effectively reducing the interference caused by the surrounding noise. In other embodiments, the active noise reduction ENC circuit 47 can also be an active noise reduction ANC circuit. The ANC noise reduction technology is to analyze the sound waves of the noise and send reverse sound waves for superposition and neutralization, thereby achieving the effect of eliminating noise.

[0049] In order to make the active noise reduction ENC circuit 47 cooperate with the rotation of the noise reduction earphone head 3 to achieve further noise reduction effect, a sensing switch 48 coupled to the main control chip is provided in the control box 41. The sensing switch 48 is a touch switch, such as an infrared sensor. When the noise reduction earphone head 3 is rotated into the ear, the sensing switch 48 is touched by hand. At this time, the sensing switch 48 connects the active noise reduction ENC circuit 47 loop (the active noise reduction ENC circuit 47 is not working at this time) and outputs a sensing signal to the main control chip. After receiving the sensing signal, the main control chip controls the active noise reduction ENC circuit 47 to work to achieve the purpose of noise reduction. In other embodiments, the sensing switch 48 may also be a micro switch, which is installed in the noise reduction earphone headphone 3 and coupled to the main control chip. When the noise reduction earphone headphone 3 is rotated into the ear, the micro switch can sense it in time and transmit the sensing signal to the main control chip. After receiving the signal, the main control chip controls the circuit where the active noise reduction ENC circuit 47 is located to be turned on, so that the active noise reduction ENC circuit 47 can work. In this way, the noise reduction earphone headphone 3 can automatically reduce noise when in use.

[0050] Reference Figure 5 The charging module 46 includes a charging port 8 electrically connected to the controller 43. The charging port 8 is installed on the control box 41 and is used for external power supply to power the controller 43. The charging port 8 is a TYPC charging port 8. In other embodiments, it can also be a USB charging port 8. In order to protect the charging port 8 from damage, a protective cover 81 is clamped on the charging port 8, and the protective cover 81 is made of rubber material.

[0051] Reference Figure 6 In order to facilitate flexible wearing of the noise reduction earphone headphone 3, in the present embodiment, the noise reduction earphone headphone 3 is rotatably connected to the bone conduction vibrator 2 through a rotating device, the rotating device includes a positioning portion 51, a knob portion 52 and a rotating portion, the positioning portion 51 is mounted on the bone conduction vibrator 2, the knob portion 52 is rotatably connected to the positioning portion 51, the rotating portion is rotatably connected to the knob portion 52, the noise reduction earphone headphone 3 is mounted on the rotating portion and coupled to the bone conduction vibrator 2 through the knob portion 52.

[0052] Reference Figure 6The positioning part 51 is a mounting block, which is mounted on the side wall of the bone conduction vibrator 2 facing away from the transmission surface of the bone conduction vibrator 2, and a rotation slot 511 is provided in the mounting block. The knob part 52 includes a support frame 521 and a knob block 522, and the knob block 522 is rotationally matched with the rotation slot 511. One end of the support frame 521 is mounted on the knob block 522, and the other end is connected to the noise reduction headphone head 3. In this embodiment, the knob block 522 is made of an elastic material, such as a composite plastic or silicone. The cross section of the knob block 522 is circular, and for this reason, it is convenient to rotate with the rotation slot 511.

[0053] Reference Figure 6 In order to further stabilize the position of the knob block 522 after rotation, a slide groove 512 connected to the rotation groove 511 is provided in the rotation groove 511, and a clamping part is installed on the knob block 522, and the clamping part and the slide groove 512 are slidably matched. In this embodiment, the clamping part is a circular ring block 61, which is surrounded by the outer wall of the knob block 522 and slidably matched with the slide groove 512. Figure 7 A locking rod 7 is rotatably connected to the knob block 522. Specifically, a through hole 525 is opened in the knob block 522, and the locking rod 7 passes through the through hole 525. An external thread is provided on the outer wall of the end of the locking rod 7 close to the rotating groove 511, and an internal thread is opened on the bottom wall of the rotating groove 511, and the internal thread cooperates with the external thread.

[0054] Reference Figure 6 When in use, the locking rod 7 is rotated, and when the internal thread and the external thread are tightened, the knob block 522 can be effectively stabilized in the rotation groove 511, referring to Figure 7 When the support frame 521 needs to be rotated, the internal thread and the external thread are unscrewed so that the end of the locking rod 7 is disengaged from the rotating groove 511. At this time, the rotating knob block 522 can easily drive the support frame 521 to rotate. The sliding cooperation between the annular block 61 and the slide groove 512 can also easily drive the support frame 521 to rotate. In addition, the rotation range of the locking rod 7 is between 0°-120°, and the user can rotate the locking rod 7 according to actual needs. The support frame 521 includes an assembly block 523 and a connecting rod 524. The assembly block 523 is mounted on the knob block 522. The cross section of the assembly block 523 is circular, and the radius is larger than that of the knob block 522. The connecting rod 524 is connected to the assembly block 523. The axis of the connecting rod 524 is perpendicular to the axis of the assembly block 523, and the radius of the connecting rod 524 is smaller than that of the assembly block 523.

[0055] Reference Figure 7 In order to facilitate the rotation of the noise reduction earphone head 3, the rotating part is the housing 31. Figure 8A slot 34 is provided in the housing 31, and the radius of the slot 34 is larger than that of the connecting rod 524. The connecting rod 524 is rotatably connected to the slot 34. In order to further stabilize the rotation of the noise reduction earphone head 3, an elastic pad 35 is provided on the side wall of the slot 34 that fits the connecting rod 524. The elastic pad 35 is a rubber pad made of rubber material, and the cross section of the rubber pad is O-shaped. In this embodiment, the rotation angle of the noise reduction earphone head 3 is between 0° and 180°.

[0056] Reference Figure 7 In order to cooperate with the rotation of the noise reduction earphone head 3 to indirectly switch the working state of the noise reduction earphone head 3, that is, in order to enable the noise reduction earphone head 3 to automatically play music after wearing the noise reduction earphone head 3, refer to Figure 8 , the signal input contact 32 of the noise reduction earphone headphone 3 is installed in the shell 31, and the signal access contact 9 of the control switch 42 is installed on the side wall of the connecting rod 524. When the noise reduction earphone headphone 3 rotates to a predetermined position following the shell 31, so that the signal input contact 32 of the noise reduction earphone headphone 3 abuts against the signal access contact 9 of the control switch 42, the control switch 42 is turned on and outputs a switch signal. At this time, the noise reduction earphone headphone 3 plays music. At the same time, the bone conduction vibrator 2 stops vibrating. When the noise reduction earphone headphone 3 deviates from the auricle position, that is, the signal input contact 32 of the noise reduction earphone headphone 3 is separated from the signal access contact 9 of the control switch 42, the control switch 42 is disconnected. At this time, the noise reduction earphone headphone 3 does not work, and the bone conduction vibrator 2 starts to work.

[0057] The implementation principle of a multifunctional bone conduction headset in an embodiment of the present application is: when a noise reduction headphone head is needed to achieve noise reduction, the noise reduction headphone head 3 is rotated so that the signal input contact 32 of the noise reduction headphone head 3 is abutted against the signal access contact 9 of the control switch 42. At this time, the noise reduction headphone head 3 is in the ear. When the noise reduction headphone head 3 is stably in the ear, the sensing switch 48 is touched by hand to allow the active noise reduction ENC circuit 47 to form a working loop to be turned on.

[0058] When the signal input contact 32 contacts the signal access contact 9, the control switch 42 is turned on and outputs a switch signal to the main control chip. At the same time, the induction switch 48 also outputs a sensing signal to the main control chip due to the induction of the hand. After the main control chip receives the switch signal and the sensing signal, it outputs a conduction signal to the working input end of the noise reduction headphone 3, and outputs a noise reduction signal to the active noise reduction ENC circuit 47. When the working input end of the noise reduction headphone 3 and the active noise reduction ENC circuit 47 receive the conduction signal and the noise reduction signal respectively, the working circuit where the noise reduction headphone 3 is located is turned on, and music starts to play, and the active noise reduction ENC circuit 47 achieves the purpose of noise reduction. At the same time, the main control chip outputs a pause signal to stop the bone conduction vibrator 2 from vibrating.

[0059] When noise reduction is not needed, the noise reduction earphone head 3 is moved away from the auricle, that is, the signal input contact 32 of the noise reduction earphone head 3 is separated from the signal access contact 9 of the control switch 42. At this time, the control switch 42 is disconnected, the noise reduction earphone head 3 does not work, and the bone conduction vibrator 2 starts to work. By rotating the noise reduction earphone head 3, the noise reduction effect can be achieved, and it is also convenient for the user to switch the working state of the noise reduction earphone head 3, thereby improving the user experience.

[0060] In addition, when it is necessary to rotate the knob block 522 to indirectly drive the noise reduction earphone head 3 to rotate, first rotate the locking rod 7 to separate the internal thread and the external thread from each other, and then rotate the knob block 522. After the knob block 522 is rotated to a suitable position, rotate the locking rod 7 again to lock the internal thread and the external thread together again. In this way, the position of the noise reduction earphone head 3 can be indirectly changed very conveniently, and the position of the noise reduction earphone head 3 can also be indirectly stabilized.

[0061] Similarly, when the noise reduction earphone headphone 3 needs to be rotated, the position of the noise reduction earphone headphone 3 can be manually rotated so that the noise reduction earphone headphone 3 is in a suitable position in the auricle. When the noise reduction earphone headphone 3 is in a suitable position for the user, the rotation can be stopped. By default, when the noise reduction earphone headphone 3 is rotated in the auricle, the signal input contact 32 of the noise reduction earphone headphone 3 and the signal access contact 9 of the control switch 42 are always in contact.

[0062] Embodiment 2:

[0063] Reference Fig. 9 The clamping part is a sliding block 64, and the cross-section of the sliding block 64 is circular. The sliding block 64 slides in the sliding groove 512. There are six sliding blocks 64, which are equidistantly arranged on the side wall of the knob block 522. The sliding cooperation between the sliding block 64 and the sliding groove 512 can effectively reduce the friction force, thereby facilitating the rotation of the knob block 522. In this way, the convenience of rotation can be effectively improved, thereby facilitating the improvement of the rotation efficiency.

[0064] Embodiment 3:

[0065] Reference Fig.10 The clamping part includes a ridge 62 and a magnetic sheet 63. The ridge 62 is provided with six ridges, which are equidistantly arranged on the knob block 522. The cross section of the ridge 62 is a semicircle, and the axis of the ridge 62 itself is parallel to the axis of the knob block 522. In order to further stabilize the position of the knob block 522 after rotation, a ridge groove 513 that is clamped with the ridge 62 is provided in the slide 512. In this embodiment, the ridge 62 is made of an elastic material, such as composite silicone or silicone. In order to further stabilize the position of the knob block 522, an iron sheet 514 is attached to the side wall of the slide 512. The iron sheet 514 is arranged opposite to the ridge groove 513. The iron sheet 514 and the magnetic sheet 63 attract each other. The magnetic sheet 63 is attached to the surface of the knob block 522 and has the same size as the iron sheet 514.

[0066] When the knob block 522 rotates in the rotation groove 511, the ridge 62 will also slide in the ridge groove 513, and the snap-fitting manner of the ridge 62 and the ridge groove 513 can further stabilize the position of the knob block 522. At the same time, it is also convenient to stably rotate the knob block 522, further improving the stability during rotation.

[0067] The present application also discloses a method of use. The method of use includes:

[0068] Obtain a switch signal, and determine whether the working circuit where the noise reduction headphone head is located is conductive based on the switch signal;

[0069] If the working circuit of the noise reduction earphone is turned on, a control signal is output to make the noise reduction earphone play music, and a pause signal is output to stop the bone conduction vibrator from working;

[0070] If the working circuit of the noise reduction earphone head is not conductive, the noise reduction earphone head will not work.

[0071] The implementation principle of a method of using an embodiment of the present application is as follows: when a switch signal is obtained, the main control chip outputs a control signal to turn on the working circuit of the noise reduction earphone head. At this time, the noise reduction earphone head plays music. When the switch signal is not obtained, the bone conduction earphone transmits the music sound through the bone conduction vibrator, and the noise reduction earphone head does not work.

[0072] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
