Description

Technical Field

[0001] This invention relates to the field of loudspeaker technology, and more particularly to a wearable audio enhancement device and its control method. Background Technology

[0002] Modern society contains a wide variety of electronic devices. Speakers, as one of the most important functions of electronic devices, are limited by the design of wearable devices, which affects the user experience. Among wearable devices, smart headphones occupy most of the market share. Similar neckband devices provide technological inspiration for wearable devices.

[0003] Research on wearable devices has revealed the following problems:

[0004] Wearable devices include smart glasses. In the smart glasses, the current from the speaker passes through a coil in a magnetic circuit composed of magnets, generating a driving force in the up and down directions to make the vibrator vibrate, which in turn makes the air vibrate and produce sound. The sound travels through the air to the area around the ear, through the external auditory canal to the eardrum. The vibration of the air causes the eardrum to vibrate, which is then transmitted to the ossicles. The ossicles are composed of three bones that form the ossicular chain, which can continue to conduct the vibration of the eardrum and transmit the sound to the inner ear. During the process of the speaker in the smart glasses transmitting sound to the ear, the sound will diffuse in all directions, causing the volume of the sound to decrease when it reaches the ear, making it difficult to hear the speaker's sound clearly.

[0005] This invention primarily addresses the problem that sound diffuses outwards during the transmission of sound from a loudspeaker to the human ear, causing the volume to decrease and making the sound inaudible. Summary of the Invention

[0006] To address the aforementioned technical problems, the present invention provides a wearable audio enhancement device and its control method to solve the problems described in the background section.

[0007] The purpose and effect of the wearable audio enhancement device and its control method of the present invention are achieved by the following specific technical means: A wearable audio enhancement device includes a frame, a lens is installed at the bottom of the frame, and a storage component for enhancing audio is provided inside the frame. The storage component includes a sleeve rod, a return spring, a push rod, a speaker base and a limiting block.

[0008] The sleeve has a return spring inside, a push rod is installed at one end of the return spring, a speaker base is installed at one end of the push rod, and a limit block is installed on the inner side of the speaker base.

[0009] Furthermore, the temples of the frame have through holes on the side facing the ear when the user is using the glasses.

[0010] Furthermore, the push rod is smaller than the opening on one side of the sleeve rod, and the end of the push rod away from the return spring is attached to the inner side of the speaker base.

[0011] Furthermore, the speaker base is mounted in the through hole of the frame via a pivot. The speaker base is semi-circular with a concave surface. A vibration transmission component is installed in the concave area. An arc-shaped through hole is formed at the edge of the semi-circular speaker base. The length of the arc-shaped through hole is two-thirds of the arc of the semi-circle of the speaker base. The remaining one-third is hollow inside. Two circular through holes are formed on the upper surface. The side near the arc-shaped through hole is open. A limit block is installed at the top edge of the opening. The bottom of the edge of the arc-shaped through hole of the speaker base is arc-shaped.

[0012] Furthermore, the vibration assembly includes a transmission block, an auxiliary plate, a hammer, a torsion spring, and a pad. An auxiliary plate is installed on the outer side of the transmission block, a pad is installed on one side of the auxiliary plate, a torsion spring is installed on the top of the pad, and a hammer is installed on one end of the torsion spring.

[0013] Furthermore, the surface of the conductive block is provided with sound transmission holes.

[0014] Furthermore, the auxiliary plate is embedded in the arc-shaped through hole at the semi-circular edge of the speaker base. The auxiliary plate is gradually inclined, and a groove is opened on its longer side near the limiting block. The size of the groove is matched with that of the limiting block.

[0015] Furthermore, the hammer is inclined, and the size of its top spherical part is smaller than the circular through hole on the upper surface of the speaker base.

[0016] Furthermore, the pad is installed at the edge of the groove in the auxiliary plate, and the pad is matched with the hollow part inside the speaker base.

[0017] Furthermore, the specific operation steps of the wearable audio enhancement control method are as follows:

[0018] S1: The frame is worn on the user's ears. The built-in sensor detects the wearing status and transmits a signal to the control module, which controls the rotating shaft to drive the speaker base to perform circular motion.

[0019] S2: The speaker base rotates through the bottom of the arc-shaped through hole edge, causing the reset spring to push the push rod and push the auxiliary plate through its own elasticity;

[0020] S3: The auxiliary plate is pushed by the force to make the conductive block gradually detach from the speaker base and fit against the user's skull. After the auxiliary plate moves, it is limited by the groove on one side and the limiting block.

[0021] S4: The pad moves outward along with the auxiliary plate to the outside of the speaker base. At this time, the pad pushes the hammer through the through hole on the upper surface of the speaker base and fits against the outer side of the conductive block.

[0022] S5: Vibration is generated during the sound production process. This vibration drives the hammer to shake. When the hammer shakes, it strikes the outer side of the transmission block at a high frequency through the torsion spring.

[0023] S6: The pressure on the push rod is intermittent while the transmission block vibrates, causing the push rod to be continuously squeezed and relaxed through the return spring, thus generating vibration;

[0024] S7: Vibrations are generated by the continuous striking of the conduction block by the push rod and the hammer and transmitted to the user's skull, thus forming bone conduction.

[0025] Beneficial effects:

[0026] 1. During the movement of the conduction block, the auxiliary plate simultaneously drives the pad to move to the outside of the speaker base. At this time, the pad pushes the torsion spring to drive the hammer to move to the outside through the through hole on the upper surface of the speaker base. The hammer is set at an angle so that it fits against the outer side of the conduction block after passing through the through hole on the upper surface of the speaker base.

[0027] 2. The current passes through the coil in the magnetic circuit composed of magnets, generating a driving force in the upward and downward directions to make the vibrating body vibrate, which in turn makes the air vibrate and produce sound. This sound is transmitted through the through hole on the surface of the conducting block. Since the conducting block is attached to the user's skull after being separated from the speaker base, it prevents the sound volume from spreading too much in all directions and reduces the sound volume when it reaches the human ear.

[0028] 3. Vibration occurs during sound generation, which drives the hammer to shake. This shaking, via a torsion spring, causes the hammer to strike the outer surface of the conduction block at a high frequency. As the conduction block vibrates, the pressure on the push rod is intermittent, causing the push rod to continuously compress and relax via the return spring, thus generating vibration. Since forces are reciprocal, the conduction block vibrates as well. This vibration, along with the vibration from the hammer striking the outer surface of the conduction block, is transmitted to the user's skull, achieving bone conduction and thus increasing audio power and improving the user experience.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0041] As attached Figure 1 To be continued Figure 9 As shown:

[0042] Example 1

[0043] A wearable audio enhancement device includes a frame 1, with a lens 101 mounted on the bottom of the frame 1. The frame 1 has an internal storage component for enhancing audio, which includes a sleeve rod 102, a return spring 103, a push rod 104, a speaker base 2, and a limiting block 201.

[0044] The sleeve rod 102 is equipped with a return spring 103 inside. A push rod 104 is installed at one end of the return spring 103. A speaker base 2 is installed at one end of the push rod 104. A limit block 201 is installed on the inner side of the speaker base 2.

[0045] Among them, the temple of the eyeglass frame 1 has a through hole on the side of the ear facing the cheek when the user is using it;

[0046] The sleeve 102 has an opening on the side near the speaker base 2, and its return spring 103 is disposed inside the opening of the sleeve 102;

[0047] Push rod 104, the size of push rod 104 is smaller than the size of the opening on one side of sleeve rod 102, and the end of push rod 104 away from return spring 103 is attached to the inner side of speaker base 2;

[0048] The speaker base 2 is mounted in the through hole of the frame 1 via a pivot. The speaker base 2 is semi-circular with a concave surface. A vibration transmission component is installed in the concave area. An arc-shaped through hole is provided at the edge of the semi-circle of the speaker base 2. The length of the arc-shaped through hole is two-thirds of the arc of the semi-circle of the speaker base 2. The remaining one-third is hollow inside. Two circular through holes are provided on the upper surface. The side near the arc-shaped through hole is open. A limit block 201 is installed at the top edge of the opening. The bottom of the edge of the arc-shaped through hole of the speaker base 2 is arc-shaped.

[0049] Wearing the frame 1 on the ear, the built-in sensor inside the frame 1 controls the rotating shaft to drive the speaker base 2 to move in a circle. The speaker base 2 is installed on the side of the ear facing the cheek, so that the speaker base 2 rotates to the user's skull. The bottom of the speaker base 2 is arc-shaped through the edge of the arc-shaped through hole, so that the return spring 103 gradually pushes the push rod 104 through its own elasticity. At this time, the push rod 104 pushes the vibration component to fit against the user's skull.

[0050] Example 2

[0051] The difference between this embodiment and embodiment 1 is that the vibration assembly includes a transmission block 3, an auxiliary plate 301, a hammer 302, a torsion spring 303, and a pad 304. The auxiliary plate 301 is installed on the outer side of the transmission block 3, the pad 304 is installed on one side of the auxiliary plate 301, the torsion spring 303 is installed on the top of the pad 304, and the hammer 302 is installed on one end of the torsion spring 303.

[0052] Among them, the conductive block 3 has a sound transmission hole on its surface;

[0053] The auxiliary plate 301 is embedded in the arc-shaped through hole at the semi-circular edge of the speaker base 2. The auxiliary plate 301 is gradually inclined, and a groove is opened on its longer side near the limiting block 201. The size of the groove is matched with that of the limiting block 201.

[0054] The hammer 302 is set at an angle, and the size of the spherical part at its top is smaller than the circular through hole on the upper surface of the speaker base 2.

[0055] The pad 304 is installed at the edge of the groove in the auxiliary plate 301. The pad 304 is matched with the hollow part inside the speaker base 2.

[0056] During the rotation of the speaker base 2, the push rod 104 gradually pushes the auxiliary plate 301 through the return spring 103, causing the conduction block 3 to gradually detach from the speaker base 2. When the speaker base 2 has rotated completely, the auxiliary plate 301, driven by the pushing force, moves the transmission block 3 outward. The groove on the longer side of the auxiliary plate 301 cooperates with the limiting block 201 to limit the movement, thereby preventing the conduction block 3 from detaching from the speaker base 2. During the movement of the conduction block 3, the auxiliary plate 301 simultaneously drives the pad 304 to move outward from the speaker base 2. At this time, the pad 304 pushes the torsion spring 303 to drive the hammer 302 to move outward through the through hole on the upper surface of the speaker base 2. The hammer 302 is tilted, so that after passing through the through hole on the upper surface of the speaker base 2, the hammer 302 is attached to the outer side of the conduction block 3. At this time, the current passes through the coil in the magnetic circuit composed of magnets, in the up and down directions. The driving force generates a vibrating body, which in turn vibrates the air, producing sound. This sound is transmitted through the through-holes on the surface of the conduction block 3. Since the conduction block 3 is attached to the user's skull after detaching from the speaker base 2, it prevents the sound volume from spreading too much in all directions, reducing the volume when it reaches the human ear. Vibration is generated during the sound generation process, which drives the hammer 302 to shake. This shaking causes the torsion spring 303 to strike the outer side of the conduction block 3 at a high frequency. While the conduction block 3 vibrates, the pressure on the push rod 104 is intermittent, causing the push rod 104 to be continuously squeezed and relaxed by the return spring 103, thus generating vibration. Since the action of force is mutual, the conduction block 3 will also vibrate at this time. This vibration, along with the vibration of the hammer 302 striking the outer side of the conduction block 3, is transmitted to the user's skull, thereby achieving the purpose of bone conduction, thereby increasing the audio power and improving the user's experience.

[0060] S2: The speaker base 2 rotates through the bottom of the arc-shaped through hole edge, so that the reset spring 103 pushes the push rod 104 to push the auxiliary plate 301 through its own elasticity;

[0061] S3: The auxiliary plate 301 is pushed by the force to make the conductive block 3 gradually separate from the speaker base 2 and fit against the user's skull. After the auxiliary plate 301 moves, it is limited by the groove on one side and cooperates with the limiting block 201.

[0062] S4: The pad 304 moves outward along with the auxiliary plate 301 to the outside of the speaker base 2. At this time, the pad 304 pushes the hammer 302 through the through hole on the upper surface of the speaker base 2 and fits against the outer side of the conductive block 3.

[0063] S5: Vibration is generated during the sound production process. This vibration drives the hammer 302 to shake. When the hammer 302 shakes, it strikes the outer side of the transmission block 3 at a high frequency through the torsion spring 303.

[0064] S6: While the transmission block 3 vibrates, the pressure on the push rod 104 is intermittent, causing the push rod 104 to be continuously squeezed and relaxed through the return spring 103, thereby generating vibration;

[0065] S7: Vibration is generated by the continuous striking of the conduction block 3 by the push rod 104 and the hammer 302 and transmitted to the user's skull, thereby forming bone conduction;
