Description

Technical Field

[0001] The present invention relates to the field of audio, and more particularly to an active aging structure of a spring wave and a suspension edge of an audio speaker. Background Art

[0002] Burn-in of audio refers to the process of conducting electrical signals for a long time to accelerate the maturation of the diaphragm (suspension) and make it reach the best working state as soon as possible, thus achieving a more pleasant sound. Since the newly purchased audio is a brand new product, the diaphragm (suspension) of the speaker unit is tightly folded, so the sound of the new audio will be dry, cold, hard, and even a little burr-like, and the low frequency is loose and lacking in volume. Therefore, it is particularly important to burn in the newly purchased audio regularly.

[0003] Since the existing speakers lack a corresponding burn-in mechanism, the existing speakers can only be burned in by playing music during the burn-in operation, so that the voice coil inside the speaker frequently hits the spring and the cone, thereby achieving the effect of aging the suspension edge at the connection of the cone, and the volume needs to be turned up as much as possible. This burn-in operation mode is not only inefficient, but also the music played for a long time during the burn-in process may generate noise and interfere with people's normal life. Therefore, we propose an active aging structure of the spring and suspension edge of the speaker to solve the above problems. Summary of the invention

[0004] 1. Technical problems to be solved

[0040] The loudspeaker 2 also includes a basin frame 201 fixedly mounted on the sound box 1, a T-iron 202 is provided at the bottom of the basin frame 201, a washer 204 is fixedly mounted on the top of the T-iron 202 via a magnet 203, a gap is provided between the T-iron 202 and the magnet 203, and a voice coil 205 is sleeved inside the gap, the top of the washer 204 is fixedly mounted to the bottom of the basin frame 201 via a connecting tube 206, a spring 207 is provided at the bottom of the inner wall of the basin frame 201, and a sound cone 209 is fixedly mounted on the inner edge of the top of the basin frame 201 via a hanging edge 208; the top of the voice coil 205 extends to the inner hole position of the spring 207 via a top tube 14 located on the lower amplitude mechanism 5 and the upper amplitude mechanism 4, and the outer edge of the top of the voice coil 205, the inner hole of the spring 207 and the inner hole at the bottom of the sound cone 209 are fixedly bonded.

[0041] (1) The burn-in principle of the active aging structure of the elastic wave and suspension edge of this type of audio speaker is:

[0042] First, the driving motor 604 of the driving mechanism 6 is powered on so that it can drive the connecting gears 10 of the upper amplitude mechanism 4 and the lower amplitude mechanism 5 to rotate at the same time, and then the two connecting gears 10 respectively drive the outer tooth edges 9 and the rotating ring 8 of the upper amplitude mechanism 4 and the lower amplitude mechanism 5 to rotate, and then a group of top columns 11 on the rotating ring 8 are driven to rotate, and through the contact connection of the ball 12 and the influence of the wavy shape structure of the wave ring 13, the top tubes 14 of the upper amplitude mechanism 4 and the lower amplitude mechanism 5 are respectively caused to vibrate up and down. At this time, the top of the top tube 14 on the upper amplitude mechanism 4 can directly contact the impact elastic wave 207, driving the sound basin 209 and the voice coil 205 to move up and down together, thereby achieving the folding and maturation effect of the hanging edge 208 at the connection of the sound basin 209, and at the same time, the top tube 14 on the lower amplitude mechanism 5 is The connection of the L-shaped connecting rod 17 drives the upper amplitude mechanism 4 to move up and down as a whole, which improves the vibration effect and can also increase the distance that the top tube 14 of the upper amplitude mechanism 4 moves up and down (it should be noted that when a group of top columns 11 of the lower amplitude mechanism 5 and the upper amplitude mechanism 4 are both rotated to the bottom of the wave crest of the corresponding wave ring 13, the top of the top tube 14 on the upper amplitude mechanism 4 is not in contact with the bottom of the elastic wave 207, so as to prevent interference with the normal music playing of the elastic wave 207 when in contact; when a group of top columns 11 of the lower amplitude mechanism 5 and the upper amplitude mechanism 4 are both rotated to the bottom of the wave trough of the corresponding wave ring 13, the top of the top tube 14 on the upper amplitude mechanism 4 is in contact with the bottom of the elastic wave 207, and the elastic wave 207 can be lifted up to achieve the effect of lifting up reciprocating vibration), which is beneficial to improving the folding and maturation effect of the hanging edge 208;

[0043] The distance between the bottom of the top column 11 and the top of the ball 12 is greater than the distance between the top of the wave crest and the bottom of the wave trough of the wave ring 13, so as to prevent the top column 11 from failing to contact the bottom of the wave crest of the wave ring 13 through the connection of the ball 12.

[0044] (2) The principle of the speaker with active spring and suspension structure is as follows:

[0045] When it is necessary to play music, the driving motor 604 of the driving mechanism 6 is first started, forcing it to drive a group of top columns 11 of the upper amplitude mechanism 4 and the lower amplitude mechanism 5 to rotate through the connection of the connecting gear 10, and controlling the group of top columns 11 of the lower amplitude mechanism 5 and the upper amplitude mechanism 4 to rotate to the bottom of the wave crest of the corresponding wave ring 13, so that the top of the top tube 14 on the upper amplitude mechanism 4 does not contact the bottom of the elastic wave 207, so as to prevent the elastic wave 207 from interfering with the normal music playing when in contact. At this time, the power supply to the driving motor 604 can be stopped, and the driving mechanism 6 stops working;

[0046] Then the voice coil 205 of the speaker 2 is connected to the circuit to generate a magnetic field, and the magnetic field of the magnet 203 causes the voice coil 205 to vibrate inside the gap, and then transmits the vibration to the elastic wave 207 and the sound cone 209, and music can be played at this time.

[0047] Embodiment 2:

[0048] In view of the above embodiment 1, for further description, refer to Figure 3 , Figure 4 as well as Figure 8 The driving mechanism 6 includes a gear box 601, one side of the bottom of the outer wall of the gear box 601 is fixedly connected to the other side of the outer wall of the base ring 7 on the lower amplitude mechanism 5, and the other side of the outer wall of the gear box 601 is fixedly installed with the other side of the inner wall of the connecting tube 206 by screws; the gear box 601 is internally rotatably connected with a transmission shaft 602, the top of the transmission shaft 602 penetrates to the outside of the top of the gear box 601, and the end of the top of the transmission shaft 602 is fixedly installed with a gear roller 1 603, the connecting gear 10 located on the upper amplitude mechanism 4 is meshed with the gear roller 1 603, and the transmission The bottom of the moving shaft 602 passes through to the outside of the bottom of the gear box 601, and a driving motor 604 is fixedly installed at the bottom of the gear box 601, and the driving shaft at the top of the driving motor 604 is connected to the bottom of the transmission shaft 602 through a coupling; a gear roller 2 605 is fixedly installed on the outer wall of the transmission shaft 602 located inside the gear box 601, and a through opening 6011 is opened on the outer wall of the gear box 601 at the position of the connecting gear 10 of the lower amplitude mechanism 5, and one side of the connecting gear 10 is meshed with one side of the corresponding gear roller 2 605 through the through opening 6011.

[0049] (3) The driving mechanism of the active aging structure of the elastic wave and suspension edge of the audio speaker works as follows:

[0050] When the driving motor 604 is started, it can drive the transmission shaft 602 to rotate. At this time, the top of the transmission shaft 602 can drive the connecting gear 10 of the upper amplitude mechanism 4 to rotate through the connection with the gear roller 1 603, and the bottom of the transmission shaft 602 can drive the connecting gear 10 of the lower amplitude mechanism 5 to rotate through the connection with the gear roller 2 605, thereby providing driving force for the rotation of the outer tooth edges 9 of the upper amplitude mechanism 4 and the lower amplitude mechanism 5.

[0051] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
