Description

New tweeter

Technical field:

The utility model relates to the technical field of audio equipment, in particular to a novel tweeter.

Background technique:

In the usual loudspeaker structure, the sound wave formed by the vibration of the sound membrane of the driver assembly is transmitted directly or transmitted through the horn diffraction. The sound wave of the horn speaker radiates sound waves to the sound field space through the diffraction of the horn. Its most prominent advantage is its high efficiency. Its efficiency is dozens of times that of the direct speaker. Very good. The existing horn structure is relatively simple. After connecting with the driver, the sound wave directly enters the input end of the horn, that is, the sound wave directly radiates to the input end surface of the horn, which results in a larger radiation surface, and the energy of the sound wave is not concentrated, that is, the sound load is small. Coupled with the energy consumption of sound waves during propagation, the propagation distance of sound waves is limited, and the effect is not ideal.

Utility model content:

The purpose of the utility model is to overcome the above-mentioned shortcomings of the existing tweeter, and provide a new tweeter structure that can increase the sound load.

The technical solution adopted by the utility model to realize its purpose is: a novel tweeter, including a tweeter driver and a horn, and an equalizer is provided at the junction of the tweeter driver and the horn, and the equalizer includes a first ring body and a second ring body. Two cones, and a circular sound wave input end is formed between the first ring body and the circular bottom of the second cone, the cone part of the second cone has two groups of symmetrical planes and arc surfaces, and the two The plane of symmetry intersects and is located within the horn, the horn has a housing corresponding to the shape of the second cone, which gaps the horn from the surface of the second cone, the housing ending in a rectangular output parallel to the intersection of said planes end; the tweeter driver is installed on the outside of the first ring body.

Through the above equalizer, the radiation surface of the sound wave generated by the treble driver is reduced to a ring, which is equivalent to compressing the sound field, so that the energy of the sound wave is concentrated, and the sound load is increased, and then passes through the gap between the equalizer and the horn. output.

Specifically, the second cone is hollow and includes a detachable cone part and a circular cover plate. Mounting lugs protrude outward from the side of the cone part. The concave part of the ear. This is beneficial to the manufacture, molding and installation of the second cone, and at the same time reduces the weight of the cone and the whole, saving costs.

The circular bottom cover is installed and fixed on the cone part of the second cone through the treble driver, and is coaxially located in the first ring, that is, forms a ring-shaped sound wave input end.

The horn is composed of a symmetrical first group of plates and a second group of plates, and the horn is in the shape of a rectangular tube gradually expanding from the rectangular output end to the end. Due to the special shape of the inner part of the horn, the one-piece molding process is complicated, so the first group of pieces and the second group of pieces are manufactured separately and reassembled, which can simplify the process and facilitate assembly and maintenance.

The outer walls of the first group of pieces and the second group of pieces of the horn are respectively formed with ribs, which have enhanced structural stability and a certain heat dissipation effect.

After adopting the above-mentioned structure, the utility model can effectively increase the sound load, enhance the directional performance of the horn and the loudspeaker, and is beneficial to the long-distance transmission of the sound, so it is suitable for professional speakers and places requiring high-power speakers.

Fig. 2 is a schematic sectional view of the utility model;

Fig. 3 is a schematic cross-sectional view of another angle of the utility model.

Detailed ways:

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figures 1 to 3, the loudspeaker of the present invention includes a tweeter driver 1 and a horn 2, wherein the tweeter driver 1 mainly includes a magnet 11, a T iron 12, a washer 13, a voice coil 14, a sound film 15 and a sound film mounting frame 16 and other parts, and the magnet 11, T iron 12, washer 13, voice coil 14, sound film 15 and sound film mounting frame 16 are all coaxially fixedly installed, and the sound film mounting frame 16 is fixed on the horn 2.

Between the treble driver 1 and the horn 2, an equalizer 3 is also installed, and the equalizer 3 includes a first ring body 31 and a second cone 32. In this embodiment, the first ring body 31 and the aforementioned tone The membrane mounting frame 16 is formed in one body and is installed on the horn 2 , that is, the sound membrane mounting frame 16 is the first ring body 31 . The second cone 32 is hollow and includes a detachable cone part and a circular cover plate 33, and the side of the cone part protrudes outwards with mounting lugs, and the corresponding horn is provided with the mounting lugs of the concave.
