Abstract

The utility model provides a full-range loudspeaker, includes magnet, iron core, basin frame, centering support piece, voice coil loudspeaker voice coil, tapered cone, book ring sum dust cap, the top of dust cap is equipped with the high pitch cup cap, the high pitch cup cap includes a tapered section of thick bamboo and arc lid, and the arc lid is established at the osculum end of a tapered section of thick bamboo, the arc lid covers on the dust cap. When the common horn is only provided with the dustproof cap, the horn body generates segmentation resonance, so that a wave trough appears on a frequency response curve of about 8K; when the treble cup cap and the dust cap are used simultaneously, the frequency response of 8K to 20K is made relatively flat and smooth. Therefore, the utility model discloses can be by ordinary loudspeaker through simply reforming transform full frequency loudspeaker.

Description

Full-frequency loudspeaker

Technical Field

The utility model belongs to the technical field of the stereo set and specifically relates to a full loudspeaker of frequency.

Background

For a cone full range speaker, a wide and flat frequency response should be desired, but in practice this is difficult to achieve due to material property limitations; because the diaphragm can generate segmentation vibration in a high-frequency section, irregular peaks and valleys are superposed on the frequency response; therefore, the improvement of the high-frequency response of the cone-shaped full-frequency loudspeaker is mainly started from the improvement of the vibration division of the vibrating diaphragm; the traditional method for improving the segmentation vibration starts from the vibrating diaphragm, and improves the high-frequency response by improving the shape and the material of the vibrating diaphragm; however, the reason that the loudspeaker generates the segmentation vibration is complex, and the shape and the material of the diaphragm can not be improved completely and effectively by improving the shape and the material of the diaphragm; furthermore, since the material of the diaphragm of the loudspeaker is limited by the state of the art and the technology of new materials, it is difficult to improve the split vibration by improving the material of the diaphragm.

Disclosure of Invention

The utility model aims to solve the technical problem that a full frequency loudspeaker is provided, simple structure, and can keep higher full-frequency sound effect.

In order to solve the technical problem, the technical scheme of the utility model is that: the utility model provides a full-range loudspeaker, includes magnet, iron core, basin frame, centering support piece, voice coil loudspeaker voice coil, tapered cone, book ring sum dust cap, the top of dust cap is equipped with the high pitch cup cap, the high pitch cup cap includes a tapered section of thick bamboo and arc lid, and the arc lid is established at the osculum end of a tapered section of thick bamboo, the arc lid covers on the dust cap. When the common horn is only provided with the dustproof cap, the horn body generates segmentation resonance, so that a wave trough appears on a frequency response curve of about 8K; when the treble cup cap and the dust cap are used simultaneously, the frequency response of 8K to 20K is made relatively flat and smooth. Therefore, the utility model discloses can be by ordinary loudspeaker through simply reforming transform full frequency loudspeaker.

As an improvement, the cone-shaped cylinder and the arc-shaped cover are integrally formed by punching and molding paper sheets.

As an improvement, the arc-shaped cover completely covers the dust cap.

As an improvement, the bottom surface of the arc-shaped cover is attached to the top surface of the dustproof cap.

Compared with the prior art, the utility model the beneficial effect who brings is:

when the common horn is only provided with the dustproof cap, the horn body generates segmentation resonance, so that a wave trough appears on a frequency response curve of about 8K; when the treble cup cap and the dust cap are used simultaneously, the frequency response of 8K to 20K is made relatively flat and smooth. Therefore, the utility model discloses can be by ordinary loudspeaker through simply reforming transform full frequency loudspeaker.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1, the full-frequency loudspeaker includes a magnet 2, an iron core 1, a cone frame 5, a centering support 3, a voice coil 4, a cone-shaped cone 7, a folded ring 8, and a dust cap 6. The utility model discloses can be reformed transform into full frequency loudspeaker through high pitch cup cap 9 by ordinary loudspeaker.

As shown in fig. 2, the tweeter cap 9 comprises a cone 91 and an arc cover 92, the cone 91 and the arc cover 92 are integrally formed by punching and molding paper sheets, the material price is low, and the manufacturing process is simple and the manufacturing cost is low by punching and molding; the two ends of the conical cylinder 91 are open, and the size of the conical cylinder 91 is determined according to the size of the horn; the arc-shaped cover is arranged at the small opening end of the cone-shaped cylinder 91 and seals the small opening end, the shape of the arc-shaped cover 92 is similar to that of the dust cap 6, and when the cone-shaped cylinder is assembled, the arc-shaped cover 92 completely covers the dust cap 6 and is bonded together by glue, so that the high-pitch cup cap 9, the dust cap 6 and the cone are coaxial.

The arc-shaped cover 92 covers the dustproof cap 6, so that the dustproof effect of the dustproof cap 6 is improved, the air leakage prevention effect is achieved, and the sound effect of high pitch is improved; in addition, the arc-shaped cover 92 is approximately in a spherical crown shape, and the arc-shaped bulge of the arc-shaped cover is beneficial to taking out the high-pressure suction nozzle and carrying out automatic assembly.

As shown in fig. 3, when the common horn is provided with only the dust cap, the horn body generates split resonance, so that a wave trough appears on a frequency response curve of about 8K; as shown in fig. 4, when the tweeter cap 9 and the dust cap 6 are used simultaneously, the frequency response of 8K to 20K becomes relatively flat and smooth. Therefore, the utility model discloses can be by ordinary loudspeaker through simply reforming transform full frequency loudspeaker.
