Problems solved by technology

[0002] Loudspeaker, also known as "horn", is a commonly used electroacoustic transducer. It can be seen in electronic and electrical equipment that emits sound. The loudspeaker is also an indispensable component of audio equipment. The performance of the loudspeaker directly affects the The sound quality of audio equipment; there are many types of speakers, among which we are more common for electric cone cone speakers, which are the most mature and widely used technology; it includes permanent magnets, core columns, paper cones, sound Ring, centering bracket, basin frame and other components, its working principle is to make the voice coil move back and forth through the change of current in the magnetic field, and then drive the paper cone to vibrate, thereby producing sound; during the sounding process, it is necessary to keep the paper cone on the axis of the stem To reciprocate vibration, so it needs the support of centering bracket, basin frame and other components; but these components themselves will form certain restrictions on the movement of the paper cone, which is easy to cause interference to the axial movement of the paper cone; especially in the process of use, Structures such as the centering bracket will age and deform. Since the aging degree of the centering bracket in all directions cannot be guaranteed to be consistent, the support strength of the centering bracket to the paper cone will change in multiple directions, which will further affect the paper cone. Vibration; at this time, the sound effect of the speaker will be greatly reduced, and serious distortion will appear

Abstract

The invention relates to an anti-disturbance loudspeaker, which comprises a shell, a permanent magnet ring, a core column, a voice coil, a paper cone and a protective cover. The guide column and the core column are coaxially arranged. Permanent magnet strips are arranged on the cylindrical surface of the guide column at equal intervals. A guide cylinder is connected between the voice coil and thepaper cone, a guide ring is arranged on the inner wall of the guide cylinder, permanent magnets are arranged on the guide ring at equal intervals, and the permanent magnets and the permanent magnets repel each other in a homopolar mode and are matched in position. The guide column also comprises a magnetism isolating ring which is close to the joint of the voice coil and the guide cylinder. The protective cover comprises a plate body and a flexible film, the plate body is arranged at the end of the guide column, and the flexible film is connected between the plate body and the guide cylinder.The loudspeaker is novel in structure and unique in principle, disturbance of parts to vibration of the paper cone can be effectively reduced, the sound production effect of the paper cone is guaranteed, the sound quality of the loudspeaker is effectively improved, and meanwhile the service life of the loudspeaker is prolonged.
