Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, in particular to a loudspeaker with a double-folded ring structure. Background Art

[0002] An electromagnetic speaker is an electroacoustic transducer that converts electrical signals into sound signals. When current passes through the voice coil of the speaker, the voice coil generates a magnetic field. This magnetic field interacts with the magnetic field generated by the permanent magnet inside the speaker, causing the voice coil to move under force. The movement of the voice coil drives the movement of the cone, and the vibration of the cone causes the surrounding air to vibrate, thereby generating sound waves.

[0003] The cone of an existing electromagnetic speaker is usually only equipped with a folding ring. The folding ring is located at the top edge of the cone and is glued to the cone frame, while the bottom of the cone is glued to the voice coil. This single folding ring structure can only provide support at the top of the cone. When the speaker is working, the voice coil and the cone move up and down together. The single folding ring structure has poor control over the concentricity of the voice coil. The voice coil may rub: the voice coil becomes eccentric during the up and down reciprocating motion and rubs against the center column of the speaker; the voice coil may also swing left and right: the voice coil swings horizontally during the up and down motion; thus affecting the sound effect and service life of the speaker. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a loudspeaker with a double folded ring structure, which can ensure the concentricity of the voice coil, the sound cone and the loudspeaker when the voice coil and the sound cone reciprocate up and down together.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A loudspeaker with a double fold ring structure, comprising a magnetic circuit system, a voice coil, a basin frame and a sound cone;

[0007] The magnetic circuit system includes a T-iron, which includes a chassis and a center column;

[0008] The voice coil is mounted on the center column;

[0009] The basin frame is installed on the magnetic circuit system;

[0010] The sound cone is arranged in the basin frame, the bottom edge of the sound cone is bonded and fixed to the voice coil, and the top edge and the inner side of the bottom of the sound cone are respectively surrounded by a first rubber edge fold ring and a second rubber edge fold ring, the first rubber edge fold ring is bonded and fixed to the basin frame, and the second rubber edge fold ring is bonded and fixed to the upper part of the center column.

[0011] In some embodiments, a tweeter assembly is also included, which includes a horn and a tweeter PCB board, a diaphragm seat and a tweeter voice coil installed in the horn. The horn is coaxially arranged with the center column and fixed to the upper part of the center column by a screw; the second rubber edge folding ring is bonded and fixed to the horn.

[0012] In at least one embodiment, a first through hole is provided on the chassis and the center column; a screw hole is provided on the diaphragm seat, and a second through hole connected to the first through hole and the screw hole is provided at the lower part of the horn; the screw passes through the first through hole and the second through hole in sequence and is threadedly connected to the screw hole.

[0013] Compared with the prior art, the present invention achieves at least the following beneficial effects:

[0014] When the speaker is working, the voice coil and the sound cone reciprocate up and down together. The first rubber edge fold ring and the second rubber edge fold ring are respectively arranged around the top edge and the inner side of the bottom of the sound cone. The first rubber edge fold ring can provide support for the sound cone, and the second rubber edge fold ring can provide support for the sound cone. The dual structure of the first rubber edge fold ring and the second rubber edge fold ring controls the up and down movement of the voice coil and the sound cone. Compared with the single structure control of the existing speaker, it can improve the stability of the voice coil and the sound cone, ensure the concentricity of the voice coil, the sound cone and the speaker, and make the central axis of the voice coil, the sound cone and the center column in the same straight line, greatly reducing the occurrence of the voice coil rubbing and swaying from side to side.

[0023] like Figures 1 to 4As shown, a loudspeaker with a double folding ring structure includes a magnetic circuit system 1, a voice coil 2, a basin frame 3 and a sound cone 4; the magnetic circuit system 1 includes a T iron 11, an annular magnet 12 and a washer gasket 13, the T iron 11 includes a chassis 111 and a center column 112, the annular magnet 12 and the washer gasket 13 are sequentially mounted on the center column 112 from bottom to top; the voice coil 2 is mounted on the center column 112; the basin frame 3 is mounted on the washer gasket 13 through a threaded connector, and a damper 30 is mounted inside the basin frame 3 and outside the voice coil 2; the sound cone 4 is arranged in the basin frame 3, the bottom edge of the sound cone 4 is bonded and fixed to the voice coil 2, and the top edge and the inner side of the bottom of the sound cone 4 are respectively surrounded by a first rubber edge folding ring 5 and a second rubber edge folding ring 6, the first rubber edge folding ring 5 is bonded and fixed to the basin frame 3, and the second rubber edge folding ring 6 is bonded and fixed to the upper part of the center column 112.

[0024] Preferably, the first rubber edge fold ring 5 is provided with two arched portions, which can more effectively control the vibration of the sound cone 4 and help to maintain the balance of the sound cone 4 during the vibration process.

[0025] The working principle of the present invention is as follows: when the loudspeaker is working, the voice coil 2 is energized to generate a magnetic field that interacts with the annular magnet 12, and the voice coil 2 and the sound cone 4 reciprocate up and down together. A first rubber edge fold ring 5 and a second rubber edge fold ring 6 are respectively arranged around the top edge and the bottom inner side of the sound cone 4. The first rubber edge fold ring 5 and the second rubber edge fold ring 6 can provide support for the sound cone 4. The dual structure of the first rubber edge fold ring 5 and the second rubber edge fold ring 6 controls the up and down movement of the voice coil 2 and the sound cone 4. Compared with the single structure control of the existing loudspeaker, the stability of the voice coil 2 and the sound cone 4 can be improved, the concentricity of the voice coil 2 and the sound cone 4 with the loudspeaker can be ensured, and the central axis of the voice coil 2, the sound cone 4 and the center column 112 are in the same straight line, which greatly reduces the occurrence of the voice coil 2 rubbing and swaying from side to side.

[0026] In some embodiments of the present invention, the speaker further comprises a tweeter assembly 7, comprising a horn 71, a tweeter PCB 72, a diaphragm seat 73, and a tweeter voice coil 74 mounted within the horn 71. The horn 71 is coaxially arranged with the center column 112 and fixedly connected to the upper portion of the center column 112 via a screw 8. The second rubber edge fold 6 is adhesively secured to the horn 71. The tweeter PCB 72 is the electrical connection center of the tweeter assembly 7 and processes the treble signal. The audio signal passes through the tweeter PCB 72 and is transmitted to the tweeter voice coil 74. The tweeter voice coil 74 vibrates under the influence of the magnetic field, driving the diaphragm of the diaphragm seat 73 to vibrate, thereby producing the treble. The horn 71 provides directionally transmitted and diffused treble.

[0027] Specifically, a first through hole 9 is provided on the chassis 111 and the center column 112; a screw hole 10 is provided on the sound membrane seat 73, and a second through hole 20 connected to the first through hole 9 and the screw hole 10 is provided at the lower part of the horn 71; the screw 8 passes through the first through hole 9 and the second through hole 20 in sequence, and is threadedly connected to the screw hole 10.

[0028] It should be noted that the voice coil 2 of the present invention is coaxially mounted on the center column 112, and the horn 71 of the tweeter assembly 7 is coaxially fixed on the center column 112. The tweeter assembly 7 and the voice coil 2 are combined on the same axis and share the same sound-emitting point. They can emit treble and bass components at the same time, thereby improving the bandwidth of the single speaker, eliminating the disadvantage that the single speaker can only emit one sound, and making the sound propagation more concentrated, thereby producing a more natural and realistic sound effect.

[0029] It should be understood that all the above embodiments are illustrative rather than restrictive. Any modifications, equivalent changes and modifications made by those skilled in the art to the specific embodiments described above under the concept of the present invention are still within the scope of the technical solution of the present invention.
