Sound box capable of enhancing sound kinetic energy

Abstract

The utility model discloses a sound box capable of realizing sound kinetic energy enhancement, comprising a box body and a box body front plate, the box body front plate is symmetrically provided with two tweeters and a mid-bass horn; a ventilation pipe independent cavity partition plate is arranged in the box body, the interior of the box body is divided into independent cavities through the partition plate, and U-shaped ventilation pipes are installed in the cavities. According to the utility model, the trend of air flow is controlled through the cooperation of the components, and a side opening or a reverse opening is reserved at the ventilation pipe by using a partition plate or enclosing the ventilation pipe. In this way, the airflow on the corners of the sound box and the middle airflow can impact the wall opposite to the inner ventilation pipe opening for approximate time and reversely impact (to form nearly doubled speed) to discharge air from the inner ventilation pipe opening, so that the kinetic energy of air movement is superposed and improved, and the low frequency is increased.

Description

Technical Field

[0001] This utility model relates to the field of audio technology, and in particular to a speaker that can enhance sound kinetic energy. Background Technology

[0002] Traditional speaker enclosures typically increase sound volume by adding straight or curved ventilation ducts (such as bass reflex designs). This enhances sound wave propagation efficiency by circulating air between the inside and outside of the enclosure. However, this existing technology has significant drawbacks:

[0003] Insufficient sound boosting power: The straight pipe structure causes the airflow to move linearly in one direction, which cannot effectively superimpose sound wave energy, resulting in weak low-frequency extension;

[0004] Decreased sound purity: There is a time difference between the airflow in the corner area and the airflow in the center reaching the ventilation opening, which produces phase interference and causes the sound quality to become muddy;

[0005] Low sound energy utilization: A large amount of air kinetic energy is lost due to disordered diffusion and cannot be converted into effective sound pressure output.

[0006] To overcome the above-mentioned defects, there is an urgent need for an innovative structure that can directionally guide airflow to counteract the flow and improve the efficiency of sound energy conversion. Utility Model Content

[0007] In order to overcome the shortcomings of the existing technology, one of the objectives of this utility model is to provide a speaker that can enhance sound kinetic energy.

[0008] One of the objectives of this utility model is achieved through the following technical solution:

[0009] A speaker capable of enhancing sound kinetic energy includes a cabinet and a front panel. Two tweeters and one mid-bass driver are symmetrically arranged on the front panel. The cabinet interior has an independent ventilation chamber partition, which divides the interior into separate chambers, each containing a U-shaped ventilation duct. A plastic panel is fixed to the side of the cabinet, integrating: track up / down and pause buttons, treble / bass / master volume control knobs, a power switch, a USB flash drive input port, a 5V DC power input port, and an Aux audio input port.

[0010] Furthermore, the two tweeters are located on the left and right sides of the front panel of the enclosure, respectively, and the mid-bass speaker is located in the center between the two tweeters.

[0011] Furthermore, the ventilation duct independent chamber partition and the inner wall of the box form a sealed chamber, and the openings at both ends of the U-shaped ventilation duct both penetrate the chamber and extend to the outside of the box.

[0012] Furthermore, the USB flash drive input port, DC 5V power input port, and Aux audio input port on the plastic panel are arranged horizontally side by side, the previous / next track and pause buttons and the power switch are located at the bottom of the panel, and the treble / bass / master volume control knob is located in the middle of the panel.

[0013] Furthermore, the bottom of the box is equipped with cushioning pads.

[0014] Furthermore, a motherboard is fixed inside the housing, and the motherboard is electrically connected to the various functional components on the plastic panel.

[0015] Furthermore, the plastic panel is securely connected to the housing via panel fixing screws.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention controls the direction of airflow through the cooperation between components. The ventilation duct is enclosed by a partition or a side opening or a reverse opening. This allows the airflow at the corners and the airflow in the middle to impact the wall opposite the inner ventilation duct opening at approximately the same time and then impact it back (resulting in a near doubling of speed) to exit from the inner ventilation duct opening. This superimposes and enhances the kinetic energy of the air movement, thereby increasing the intensity of low frequencies.

[0018] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings.
