Abstract

The present invention relates to a speaker system with a wide horizontal coverage angle. As shown in fig. 1 and 2, the small-sized tweeter unit 1 is arranged in front of the woofer unit 2 in a number N, the left and right sides of the woofer unit 2 are provided with the acoustic covers 3, and as can be seen from fig. 2, a gap for vibrating the diaphragm is left between the covers 3 and 2, and the cover and the horn rim are sealed, so that the sound wave can radiate only from the inside of the cover.

Claims (3)

  1. 1. A speaker system with a wide horizontal coverage angle is characterized in that a total of N small-sized tweeters are vertically arranged in front of a single mid-bass unit.
  2. 2. The left side and the right side of the vibrating diaphragm of the middle bass unit are provided with covering pieces for covering, and enough gaps are reserved between the covering pieces and the vibrating diaphragm of the loudspeaker so that the loudspeaker cannot collide with the covering pieces when vibrating.
  3. 3. The outside of the cover is closed so that sound waves can only propagate out of the inside of the cover.

Description

Horizontal coverage angle wide loudspeaker system Technical Field The invention relates to the field of sound box equipment, in particular to a background technology of a loudspeaker system with wide horizontal coverage angle In a typical speaker system, a relatively compact layout is obtained by using a configuration in which the high-pitched sound is distributed on two sides of the opening of the high-pitched sound, and the middle-pitched sound is distributed on 2 or more sides of the opening of the high-pitched sound, which causes a problem in that two units distributed on two sides of the high-pitched sound are horizontally spaced apart from each other relatively far, resulting in a narrowing of the horizontal coverage angle of the middle frequency, and a wider coverage angle is required by means of a lower crossover frequency or by adding a separate middle-pitched sound speaker, thereby increasing the structural complexity and cost. Disclosure of Invention The present invention provides a simple and very compact acoustic solution, in which a plurality of small-sized treble units, 1 in fig. 1 and 2, are arranged vertically right in front of only one mid-bass unit 2, The left and right sides of the mid-bass unit are provided with acoustic covering pieces 3 which cover the positions of the diaphragms at the left and right sides, and enough gaps are left between the covering pieces and the diaphragms so that the diaphragms can not strike the covering pieces when the mid-bass unit works, The outside of the cover is sealed so that sound waves can only be emitted from the middle of the loudspeaker. Drawings Fig. 1 is a front view of the present invention, i.e. the distribution of loudspeakers as seen from the front of the listener; Fig. 2 is a plan view of the present invention, showing the front-rear positional relationship of a small-sized high-pitched unit, a medium-pitched unit, and an acoustic cover.
