Abstract

The present invention relates to a loudspeaker enclosure with high airflow efficiency. The loudspeaker enclosure has a hollow shell and a lid. An opening is set in front of the hollow shell. Two corresponding sidewalls of the hollow shell extend to a backside wall of the hollow shell respectively from a periphery of the opening in a convergent manner with a wavy shape. The other two corresponding sidewalls of the hollow shell extend in parallel to the backside wall respectively from the periphery of the opening. The backside wall has a wall with backward convergence. The size of the lid could fix the periphery of the opening. At least one woofer and a bass reflex hole are disposed on the lid. When a drumhead of the woofer generates a vibration, a gas within the hollow shell is guided and gathered to an inside of the backside wall which corresponds to a position of the bass reflex hole through the two sidewalls with the wavy shape and the backside wall with backward convergence. The gas is then discharged to an outside via the bass reflex hole. Therefore, the compressed gas within the hollow shell and the vibration of the drumhead influenced by the negative pressure may not only be reduced substantially, but may be able to improve bass quality and volume for the woofer.

Description of the invention (4) Evenly bounced to the inside of the cover 12, only a small part of it is reflected out through the bass reflection hole 1 2 2 and the rest is not only unnecessary for the cover 12 The vibration of the bass and the tympanic membrane of the bass 1 2 0 1 negatively affects the phenomenon of bass distortion, which makes the traditional bass speaker structure in the quality and quantity of bass output is always difficult breakthrough. SUMMARY OF THE INVENTION In view of the foregoing tradition. Many Insufficient Designs of the Eight Speaker Structure Design 'The inventor has developed one of the eighth speaker structure with high airflow efficiency of the present invention based on many years of practical experience and research experience. One object of the present invention is to design the corresponding side wall of one of the hollow shells of one of the loudspeakers and speakers to be wavyly extended from the opening periphery to the back side wall in a tapered manner. The two side walls, which are designed to be wavy and tapered backward, make the ratio between the cross-sectional area adjacent to the opening and the cross-sectional area adjacent to the back side wall large, so as to vibrate and oscillate the tympanic membrane of the bass. When a backward pushing force is applied to the gas in the hollow shell, the gas in the hollow shell can be caused to rapidly flow backward along the two side walls designed to be wavy and tapered backward, and adjacent to the The inner side of the back side wall generates an airflow with higher kinetic energy, which makes the speaker ' s loudspeaker produce a stronger low-frequency co-vibration effect, and the gas that bounces back toward the opening when it hits the back side wall, because the two side walls present The wavy design gradually shrinks backwards, and bounces back to the position of at least one bass reflection hole designed on the cover, and smoothly bounces the gas that bounces back through the bass reflection hole to the outside, making the hollow shell Inside Gas flow more smoothly, so as to effectively reduce the secondary sound waves ^

Description of the invention (5) Probability of shooting. Another object of the present invention is to design the tie wall by a design in which the flat peripheral side wall of the opening is adjacent to the oblique wall surface adjacent to the other two corresponding side walls and each of the other two correspondingly tapered backwards. Gas application-smoothly guided to the position of the back. In this way, when the gases bounce back, they can bounce more concentratedly through the bass reflection hole and smoothly reduce the amplitude of the compressed gas in the hollow shell. The tympanic membrane vibration causes a negative effect. With another object of the present invention, the rear edge of the bass reflection hole in the hollow casing can be sequentially passed through the two wavy-shaped back side walls and passed through the hollow casing. Due to the negative pressure in the body, the hole 'smoothly introduces the hollow shell, which greatly reduces the negative impact of the compressed gas in the hollow shell, and can therefore effectively stiffen the other side of the hollow shell. Extending to the back side wall, the position of the back is connected with an arc or inclined side wall, respectively, and when the drum wall of the back side wall is oscillated, the gas is caused by the force of the backward push. The inside of the side wall corresponds to the Reflection sound hole of the back side wall and across to the direction of opening to the position of the bass reflex apertures to bounce back through the gas is emitted to the outside, a large negative effect on the body and a bass σ barbed Α reduce the distortion of the bass phenomenon. When the tympanic membrane of the bass beta 8 vibrates, the corresponding side wall and the compressed gas designed to be tapered backwards are smoothly guided to the bass reflection hole and emitted outward, or the outside air is passed through the bass reflection body. This structural design can not only cause the body and negative pressure to cause the eardrum to vibrate, but also improve the bass quality and sound of the bass system.

The eight-speaker structure 20 produces a stronger low-frequency co-vibration effect. In addition, it is particularly important to note that when the gas flowing rapidly along the two side walls 2 11 which is designed to be tapered backwards gradually hits the back side wall 2 1 2 and bounces back in the direction of the opening 2 10, due to the The arc surface on the two side walls 2 1 1 which is adjacent to the back side wall 2 1 2 is bent outward from the hollow shell 2 1, so the rebounded gas will bounce back to the sink along the tangent line 2 11 1 of the arc surface.该盖 The cover

Description of the invention (9) The airflow with higher kinetic energy is concentrated on the inner side of the back side wall 2 1 2 corresponding to the bass reflection hole 2 2 2. In this way, these gases are hitting the back When the side wall 212 bounces back in the direction of the opening 210, it can be concentrated and bounced back to the rear edge of the bass reflection hole 2222, and the bounced gas can be smoothly emitted through the bass reflection hole 222 'to the outside. In summary, the horn speaker structure 2 of the present invention, when the tympanum 2 2 0 1 of the woofer 2 2 0 is vibrated, the corresponding side walls 2 11 and the rearward side of the wave-shaped design can be sequentially used. The tapered design of the back side wall 2 1 2 smoothly guides and condenses the gas in the hollow casing 21 to the inside of the back side wall 2 1 2 corresponding to the trailing edge position of the bass reflection hole 222 and passes through the bass The reflection holes 2 2 2 are emitted to the outside, or the negative pressure in the hollow casing 21 is used (when the eardrum 220 1 is moved forward), and the outside air is passed through the bass reflection holes 2 2 2 to guide smoothly. Introduced into the hollow casing 21, this structural design can not only make the air flow in the hollow casing 21 smoother, effectively reduce the probability of secondary reflection of the bass waves', but also significantly slow down the hollow casing 21 Compressed gas and negative pressure have a negative effect on the vibration of the tympanum 220 1 of the bass π π 220 to effectively reduce the phenomenon of bass distortion, and therefore can effectively improve the bass quality and volume of the bass speaker. The above description is only a preferred embodiment of the present invention, but the scope of rights claimed by the present invention is not limited to this. According to the technical content disclosed by the person skilled in the art based on the present invention, one can easily think about it. And equivalent changes, all should not depart from the protection scope of the present invention.
