Description

Hi-Fi loudspeaker without basin stand

Technical Field

The utility model relates to an audio equipment field specifically indicates a high-fidelity loudspeaker of no basin frame.

Background

The loudspeaker box can also be used as a loudspeaker, and the loudspeaker box is widely used in the current market as an electrodynamic loudspeaker. When the voice coil serving as the current-carrying conductor inputs alternating audio current, the voice coil can generate alternating motion by an alternating driving force, so that the cone is driven to vibrate, the cone vibrates to drive air to vibrate, and finally, the audio electric signal is converted into sound waves. The cone speaker among the electro-dynamic speakers is the most produced speaker in the world.

However, most of the existing paper cone type speakers (speakers) mainly mount components (such as voice coils, elastic waves and drum paper) for generating vibration on a cone frame for supporting, but most of the existing cone frames are only provided with 4 cone frame windows, when the voice coils are subjected to magnetic force division in a magnetic field to drive the drum paper to generate up-and-down vibration, the waveform of sound waves caused by the vibration of the drum paper is transmitted to the periphery and the front end along the bonding part of the voice coils and the drum paper, when the sound waves meet the wall of the cone frame, the sound waves are reflected back to interfere with other waveforms, and the windows of the cone frame are small, so that the natural circulation of air flow is obstructed, and the existence of the cone frame can cause serious distortion of the speakers.

When the loudspeaker converts the audio electrical signal into the sound wave signal, when the voice coil moves up and down due to vibration, the drum paper mounted on the voice coil is also subjected to downward or upward pulling force, the bowl opening of the drum paper can be distorted and deformed due to insufficient rigidity, the drum paper can be distorted and twisted into a twist shape severely, and the loudspeaker with the deformed drum paper can output abnormal sounds such as serious distortion or confusion.

Therefore, based on the background, the utility model provides a high-fidelity loudspeaker of no basin frame.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome the defect of above-mentioned technique, provide one kind and can avoid the basin frame to lead to the high-fidelity loudspeaker of loudspeaker sound distortion to the sound wave reflection.

A high fidelity type loudspeaker without a basin frame has the technical scheme that:

It is right to the utility model discloses further describe, the drum paper has an annular non-deformable's ring towards the one side rigid coupling of the siding wall of audio amplifier, and the distortion that upwards or decurrent power that the design of ring can avoid the drum paper to receive along with the upper and lower vibration of voice coil loudspeaker voice coil arouses, and this can avoid the sound distortion that leads to because of the drum paper warp or mix the appearance of the unusual circumstances such as unclear, can further improve loudspeaker's fidelity effect.

To further describe the present invention, the hard ring is close to the lower edge of the rim of the drum paper.

As a further description of the present invention, the hard ring is made of one of iron wire, hard plastic or hard paper.

To the utility model discloses further describe, the iron core is T shape iron core or U-shaped iron core.

By adopting the technical scheme, the beneficial effects are as follows:

the utility model discloses a loudspeaker simple structure, it is with low costs, and have the effect of high-fidelity.

The utility model eliminates the structure of the basin frame, on one hand, the problem of loudspeaker sound distortion caused by unsmooth circulation of air flow due to the reflection of sound waves generated by the vibration of the drum paper by the basin frame wall of the basin frame and the small window of the basin frame can be avoided, and the fidelity effect of the loudspeaker is improved; on the other hand, the cost of the loudspeaker frame can be saved by eliminating the frame, and the manufacturing cost of the loudspeaker is reduced; just the utility model discloses the hard circle that increases on the drum paper can avoid receiving the distortion that upwards or decurrent power leads to because of the drum paper serious distortion of sound or mix the appearance of the unusual circumstances such as unclear, its fidelity effect that can further strengthen loudspeaker.
