technical field

The utility model relates to the field of audio technology, in particular to a long-range road show sound box.

Background technique

With the continuous progress of the times, speakers have become one of the indispensable products for people. The existing speakers are large and small, and their functions are not the same. Most of the existing speakers are fixed speakers, and there are mobile speakers. Form. However, for small mobile performance groups, it is impossible to have too many speakers due to the limitations of transportation means, personnel and stage, generally they are traditional speakers, so it is very important to have a speaker with long-range sound pressure. It is imperative to study a roadshow speaker with long range and high pressure suitable for small roadshows.

Utility model content

The purpose of this utility model is to provide a long-range roadshow sound box to solve the problems raised in the above-mentioned background technology.

In order to achieve the above purpose, the utility model provides the following technical solutions: a long-range road show speaker, including a box and a common horn for mid- and high-pitched sounds, a bass horn is installed on the bottom of the front of the box, and a bass horn is installed on the back of the bass horn Speaker, the back of the woofer horn is provided with an inverter hole, the woofer is provided with two, and the inverter hole is located between the woofers, the top of the woofer horn is fixedly bonded with a connecting plate, and the middle and high-pitched The horn is set above the front of the box body, and the common horn for the middle and high pitch is fixedly bonded to the upper surface of the connecting plate. A high-pitched horn is fixedly bonded to the back of the common high-pitched horn, and a tweeter is fixedly bonded to the top of the high-pitched horn. A partition plate is installed on the side of the public high-pitched horn, and the other end of the partition plate is fixedly bonded to the box. in vivo.

Preferably, the numbers of the tweeter horns and the midrange speakers are two and four respectively.

Preferably, two phase-inversion holes are designed, and the phase-inversion holes are located on both sides between the woofers.

Preferably, a midrange cavity is formed between the partition plate and the side of the cabinet and the common midrange horn.

Preferably, a bass cavity is formed between the partition plate and the upper surface of the cabinet and the common horn for the middle and high pitch.

Compared with the prior art, the beneficial effect of the utility model is that the structure of the long-range road show speaker is simple:

1. The cabinet adopts the continuation technology of double treble horns and common mid-range horns. The mid-range horn is used as a continuation of the treble horns, thus achieving a long range;

2. The high-middle-bass speaker units have been arranged in the best mode, so that the positive superposition of each speaker has been carried out, and the sound pressure level has been improved.
