Description

Technical Field

[0002] Speakers are a crucial component of audio equipment. Their fundamental principle is to convert electrical signals into sound waves using the electromagnetic effect. During speaker operation, the voice coil is a key component in producing sound.

DETAILED DESCRIPTION

[0033] The present invention is further described with reference to the following examples.

[0034] Depend on Figures 1 to 7 It can be seen that the loudspeaker with voice coil horizontal deviation correction described in this embodiment includes a bracket 11; the bracket 11 is provided with an opening; a diaphragm 2 is provided at the opening; an annular voice coil 3 is provided at the bottom of the diaphragm 2; a coil 31 is wound around the annular voice coil 3; an annular magnet 41 is provided at the bottom of the bracket 11; a T-shaped yoke 42 is provided at the bottom of the annular magnet 41; a cylindrical limiter 5 is provided at the middle of the T-shaped yoke 42; the cylindrical limiter 5 protrudes into the annular magnet 41; the annular voice coil 3 is movable between the annular magnet 41 and the cylindrical limiter 5; the annular voice coil 3, the annular magnet 41 and the cylindrical limiter 5 are arranged concentrically;

[0035] The outer wall of the cylindrical limiter 5 is provided with a plurality of upper air vents 51 at equal angles along the circumference; the outer wall of the cylindrical limiter 5 is provided with a plurality of lower air vents 53 at equal angles along the circumference; the plurality of upper air vents 51 are interconnected; the plurality of lower air vents 53 are interconnected; the loudspeaker with corrected voice coil horizontal deviation also includes an air supply mechanism for providing gas to the upper air vents 51 and the lower air vents 53; wherein the plurality of upper air vents 51 are at the same height, and the plurality of lower air vents 53 are at the same height.

[0036] Specifically, the loudspeaker with corrected voice coil horizontal deviation described in this embodiment, when in use, ventilates all the upper vent holes 51 and / or the lower vent holes 53 through the air supply mechanism. Since the plurality of upper vent holes 51 are arranged at equal angles and heights around the outer wall of the cylindrical limiter 5, and the plurality of lower vent holes 53 are arranged at equal angles and heights around the outer wall of the cylindrical limiter 5, when the annular voice coil 3 does not deviate in the horizontal direction and is lifted and lowered in the vertical direction, that is, the inner wall of the annular voice coil 3 is at the same distance from the cylindrical limiter 5 at each position, the air ejected from the cylindrical limiter 5 The force can be uniformly applied to the circumferential direction of the annular voice coil 3; when the annular voice coil 3 deviates in the horizontal direction, part of the inner wall of the annular voice coil 3 will be closer to the cylindrical limiter 5, and part of the inner wall of the annular voice coil 3 will be farther away from the cylindrical limiter 5, so that the gas ejected by the cylindrical limiter 5 exerts a greater force on the inner wall of the annular voice coil 3 that is closer, and the gas ejected by the cylindrical limiter 5 exerts a smaller force on the inner wall of the annular voice coil 3 that is farther away, thereby driving the annular voice coil 3 to move in the horizontal direction and correcting the horizontal position deviation of the annular voice coil 3.

[0037] In the speaker with corrected voice coil horizontal deviation described in this embodiment, the diaphragm 2 includes a vibrating portion 21 and a fixing portion 22 disposed around the vibrating portion 21; the fixing portion 22 is connected to the opening of the bracket 11. Specifically, the above arrangement makes the overall structure stable and reliable.

[0038] In the loudspeaker with corrected voice coil horizontal deviation described in this embodiment, the air supply mechanism includes a housing 6 and an upper annular sleeve 7; the upper annular sleeve 7 is disposed between the bottom of the T-shaped yoke 42 and the bottom of the housing 6;

[0040] Specifically, in this embodiment, a piston 67 is provided. During the movement of the piston 67 in the air cavity, the volume of the upper air cavity 61 and the lower air cavity 62 is changed, thereby supplying air to the upper air vent 51 and the lower air vent 53 .

[0041] The present embodiment describes a loudspeaker for correcting horizontal deviation of a voice coil, wherein the shell 6 is provided with an upper air inlet 63 connected to an upper air cavity 61 and a lower air inlet 64 connected to a lower air cavity 62; the cylindrical limiter 5 is provided with a plurality of upper air ducts 52 connected to the upper air vents 51 and a plurality of lower air ducts 54 connected to the lower air vents 53; the upper air vents 51 and the upper air ducts 52 are arranged in a one-to-one correspondence; the lower air vents 53 and the lower air ducts 54 are arranged in a one-to-one correspondence; an upper cavity 71 is provided in the upper annular sleeve 7; the upper air duct 52 and the upper air cavity 61 are respectively connected to the upper cavity 71; a lower annular sleeve 8 is provided in the lower air cavity 62; a lower cavity 81 is provided in the lower annular sleeve 8; the lower air duct 54 and the lower air cavity 62 are respectively connected to the lower cavity 81.

[0042] Specifically, in the loudspeaker with voice coil horizontal deviation correction described in this embodiment, when the piston 67 moves downward, the volume of the upper cavity 71 increases and the pressure decreases, and the volume of the lower cavity 81 decreases and the pressure increases; at this time, the first valve plate 65 opens, the third valve plate 73 closes, and the external gas enters the upper air cavity 61 through the upper air inlet 63; at the same time, the second valve plate 66 is closed, the fourth valve plate 83 is opened, and the gas in the lower air cavity 62 enters the lower cavity 81 through the lower inlet 82, and is evenly ejected from the lower air vent 53 after passing through the lower air duct 54.

[0043] When the piston 67 moves upward, the volume of the upper cavity 71 is smaller and the pressure increases, and the volume of the upper cavity 71 increases and the pressure decreases; at this time, the first valve plate 65 is closed, and the third valve plate 73 is opened. The gas in the upper air cavity 61 enters the upper cavity 71 through the upper inlet 72, and is evenly ejected from the upper air vent 51 after passing through the upper air duct 52; at the same time, the second valve plate 66 is opened, and the fourth valve plate 83 is closed, and the external gas enters the lower air cavity 62 through the lower air inlet 64.

[0044] In the speaker with corrected voice coil horizontal deviation described in this embodiment, the lower annular sleeve 8 is provided with an air pipe 84 connected to the lower cavity 81; the air pipe 84 passes through the piston 67 and the housing 6 and is connected to the lower air channel 54. This arrangement makes the overall structure stable and reliable.

[0045] In the loudspeaker with corrected voice coil horizontal deviation described in this embodiment, a push rod 68 is provided after the piston 67 passes through the shell 6; the push rod 68 passes through the cylindrical limiter 5 and is connected to the middle of the diaphragm 2; the push rod 68 is passed through the upper annular sleeve 7; wherein the push rod 68 passes through the cylindrical limiter 5 and is connected to the middle of the vibration part 21.

[0046] Specifically, through the above-mentioned arrangement, when the annular voice coil 3 vibrates, the diaphragm 2 is driven to move up and down, so that when the diaphragm 2 moves downward, the piston 67 is driven downward by the push rod 68; and when the diaphragm 2 moves upward, the piston 67 is driven upward by the push rod 68; through the above-mentioned arrangement, this embodiment enables the annular voice coil 3 to alternately eject gas from the upper air vent 51 and the lower air vent 53 during operation without the need for an additional driving source.

[0047] In the loudspeaker for correcting the horizontal deviation of the voice coil described in this embodiment, the height of the upper air vent 51 is higher than the height of the lower air vent 53; the inner wall of the annular voice coil 3 is provided with a plurality of upper guide blocks 91 along the circumferential direction; the inner wall of the annular voice coil 3 is provided with a plurality of lower guide blocks 93 along the circumferential direction; the plurality of upper guide blocks 91 are arranged in a one-to-one correspondence with the plurality of upper air vents 51; the plurality of lower guide blocks 93 are arranged in a one-to-one correspondence with the plurality of lower air vents 53; the bottom of the upper guide block 91 is provided with an upper inclined surface 92 inclined upward toward the direction of the cylindrical limiter 5; the top of the lower guide block 93 is provided with a lower inclined surface 94 inclined downward toward the direction of the cylindrical limiter 5; the upper inclined surface 92 is arranged opposite to the upper air vent 51; and the lower inclined surface 94 is arranged opposite to the lower air vent 53.

[0048] Specifically, through the above arrangement, when the annular voice coil 3 moves downward, the diaphragm 2 is driven to move downward, and the piston 67 is driven downward by the push rod 68; the volume of the upper cavity 71 increases and the pressure decreases, and the volume of the lower cavity 81 decreases and the pressure increases; at this time, the first valve plate 65 is opened and the third valve plate 73 is closed, and the external gas enters the upper air cavity 61 through the upper air inlet 63; at the same time, the second valve plate 66 is closed and the fourth valve plate 83 is opened, and the gas in the lower air cavity 62 enters the lower cavity 81 through the lower inlet 82, and is evenly ejected from the lower air vent 53 after passing through the lower air channel 54; since the lower inclined surface 94 is arranged opposite to the lower air vent 53, the gas ejected from the lower air vent 53 acts on the lower inclined surface 94, thereby generating a downward force on the annular voice coil 3, which can increase the amplitude of the annular voice coil 3, which enables the speaker to reduce its working power input without reducing the sound quality while meeting the playback effect.

[0049] When the annular voice coil 3 moves upward, it drives the diaphragm 2 to move upward, and drives the piston 67 upward through the push rod 68; the volume of the upper cavity 71 is smaller and the pressure increases, and the volume of the upper cavity 71 increases and the pressure decreases; at this time, the first valve plate 65 is closed and the third valve plate 73 is opened, and the gas in the upper air cavity 61 enters the upper cavity 71 through the upper inlet 72, and is evenly ejected from the upper air vent 51 after passing through the upper air channel 52; at the same time, the second valve plate 66 is opened and the fourth valve plate 83 is closed, and the external gas enters the lower air cavity 62 through the lower air inlet 64; since the upper inclined surface 92 is arranged opposite to the upper air vent 51, the gas ejected from the upper air vent 51 acts on the upper inclined surface 92, thereby generating an upward force on the annular voice coil 3, which can increase the amplitude of the annular voice coil 3, which enables the speaker to reduce its working power input without reducing the sound quality while meeting the playback effect.

[0051] In this embodiment of a speaker with corrected voice coil horizontal deviation, a diaphragm 12 is disposed between the bracket 11 and the annular voice coil 3. The speaker also includes a housing 1. The bracket 11, annular magnet 41, T-yoke 42, shell 6, and upper annular sleeve 7 are all disposed within the housing 1. This arrangement protects the speaker components.
