High-fidelity multipurpose loudspeaker box system

Abstract

The invention discloses a high-fidelity multipurpose loudspeaker box system which comprises a low-pitch loudspeaker, a full-frequency loudspeaker, a low-pitch box body, a middle-high-pitch loudspeaker, a low-pitch frequency divider and a loudspeaker box base. The low-pitch loudspeaker and the low-pitch frequency divider are connected through a circuit, the low-pitch frequency divider is arranged in the loudspeaker box base, and the low-pitch loudspeaker and the full-frequency loudspeaker are both connected with a binding post on the loudspeaker box base. The low-pitch box body is provided with a straight through cavity, one end of the cavity is open, the other end of the cavity is connected to the loudspeaker box base, and the low-pitch loudspeaker is arranged at the opening formed one end of the cavity. The middle-high-pitch loudspeaker comprises a semi-circular bent pipe and a conical pipe, one end of the semi-circular bent pipe is connected with the upper portion of the low-pitch loudspeaker, the other end of the semi-circular bent pipe is communicated with the opening formed in the smaller end of the conical pipe arranged horizontally, the conical pipe is located above the opened end of the low-pitch box body, and the full-frequency loudspeaker is arranged at the opening formed in the large end of the conical pipe. The high-fidelity multipurpose loudspeaker box system reduces the influence of environmental acoustic conditions on a listening effect and is suitable for usage in a home environment on which strict acoustic treatment is not conducted.

Description

technical field [0001] The invention relates to the field of audio processing and playback, in particular to a high-fidelity multipurpose sound box system. Background technique [0002] In the prior art, the loudspeaker speakers of the home audio-visual entertainment system can basically be divided into two categories: one is a two-channel Hi-Fi stereo speaker, mainly for listening to music, and the users of this type of speaker are mostly music or audio equipment For audiophiles, they often have very strict requirements on sound quality. Because this kind of speakers mainly pursue high-fidelity and pleasant timbre in music expression, most of them are lacking in presence and low-frequency dynamic performance. Watching movies in home theater is often unsatisfactory; the other type is multi-channel AV home theater speakers. Because this kind of speakers are mainly for watching movies, they often cannot meet the requirements for high sound quality when listening to music. Dem...

Problems solved by technology

[0008] However, the Pluto speaker system still has the following obvious defects: 1) The 5.5 o'clock woofer used in the Pluto audio system is an aluminum alloy vibrating basin, while the 2 o'clock full-range speaker uses a titanium alloy vibrating basin, which plays human voices. 2) The upper limit of the frequency response of the full-range speaker responsible for mid-high frequency playback is only 15kHz, and the high-frequency extension is obviously insufficient, so its high-frequency details, brightness, and transparency are lacking; 3) Because the rated power of the full-range speaker selected by Pluto is low, the caliber of its woofer is not large enough, the lower limit of low frequency is not deep enough, and the power is relatively not large enough, its application range is relatively limited; 4) Since Pluto uses electronic frequency division (also It is called the pre-stage crossover), the power amplifier must be bundled with the speaker (that is, the active speaker), and cannot be connected to other power amplifiers, thus limiting the compatibility of the speaker system with other power amplifier systems, and also limiting the user's ability to seek More freedom of choice for a richer tone-changing experience
