Problems solved by technology

Its goal is to control the angle of the sound wave at 6° flat, and the width is within the range of a flat and wide triangle shape of 120°, so the angle is too large, and the low-frequency effect is not good.

Abstract

The invention discloses a high-frequency sound wave focuser. The high-frequency sound wave focuser comprises a cone core, a truncated cone core and a horn, wherein the diameter of the larger end of the truncated cone core is equal to the diameter of the bottom face of the cone core, and the larger end of the truncated cone core is connected with the bottom face of the cone core; the cone core is arranged in a cavity of the horn; and intervals are set between the horn and the cone core. The invention further provides a sound focusing unit. The sound focusing unit is composed of the high-frequency sound wave focuser and a coaxial loudspeaker. The high-frequency sound wave focuser is arranged on a high pitch outlet of the coaxial loudspeaker, and the horn is connected with the coaxial loudspeaker. According to the invention, frequency division between the high pitches and low pitches is available, interference of different frequencies are overcomed, and the timbre is accurate; high pitch and low pitch loudspeakers can be selected and matched freely to ensure a high fidelity effect of the timbre; and the output power and the sound pressure level are substantially promoted, and both the high-frequency sound wave focuser and the sound focusing unit are high in work efficiency.

Description

technical field [0001] The invention relates to a high-frequency sound wave focuser. Background technique [0002] At present, the application of tweeters in the market requires sound waves to be used at a certain projection angle. There is a loudspeaker using planar magnetic technology that can control the angle of high-frequency sound waves to a small size. But its sound quality is poor, and the sound pressure of UHF and ULF is low. The reason is that a planar magnetic speaker works with a large diaphragm, and all sound frequencies are emitted on one diaphragm. Therefore, the superposition and cancellation of different frequencies will occur on the diaphragm to affect the sound quality. [0003] There is also a product that installs a horn on a coaxial horn. A horn is installed on the paper cone bass, and an ax-like core is installed in the treble horn. Its goal is to control the sound wave angle to be 6° flat and 120° wide within a flat and wide triangular shape rang...
