Barrel-shaped directional speaker structure

The invention relates to a barrel-shaped multi-directional horn speaker structure, in particular, a accommodating space is formed in a hollow casing, a horn is arranged in the accommodating space, and a concave surface is formed on the outer edge of the hollow casing. a plurality of directional grooves are provided, and the directional grooves are connected to the accommodating space, so that the sound generated by the horn in the accommodating space can be oriented through the directional grooves surrounding the barrel respectively. A speaker structure that is transmitted to a peripheral space other than the front end of the hollow casing.

According to the rapid growth of various industrial technologies, various multimedia products continue to innovate, greatly satisfying people's enjoyment in sight and hearing. In general, in order to make full use of the resonance effect of sound waves to achieve a good sound field effect, the manufacturer will set a bass or tweeter in a speaker to use the cavity inside the speaker as a resonance chamber.

Referring to FIG. 1 , a speaker structure 10 is known. The speaker structure 10 mainly includes a hollow casing 11 and a cover body 12 . The hollow casing 11 is provided with an opening 110 on the front side thereof. The two corresponding side walls 111 of the housing 11 are linearly extended from the circumference of the opening 110 to the back side wall 112 in a tapered manner, and the other corresponding side walls 113 of the hollow housing 11 are respectively surrounded by the opening 110. Parallelly extending rearwardly to the back side wall 112 thereof, the mounting frame 16 can be pivotally connected to the hollow housing 11 to be mounted and fixed to a proper position. The hollow housing 11 is located at the back side wall 112. On the inner side, a sound source control circuit 13 is provided for receiving the sound source signal from the sound amplifier (not shown) and performing sound source control processing thereon; the cover body 12 is provided with a woofer 120, a tweeter 121 and at least one bass reflex hole 122, the cover body 12 is sized to be fixed to the periphery of the opening 110, so that the high frequency and low frequency sound source signals generated by the sound source control circuit 13 Can be separately transmitted to the woofer 120 and the tweeter 121, stimulating the tympanic membrane vibration of each of the horns 120, 121 to generate high frequency and low frequency sound effects, respectively. Generally speaking, the cover 12 of the speaker structure 10 and the sound source control circuit 13 A sound absorbing material 14 made of non-woven fabric or foam is placed between the sound absorbing material 14 to absorb the bass amplitude, and the signal line and the power line on the sound source control circuit 13 are prevented from generating low frequency resonance, which causes poor bass sound. In addition, a dust-proof cover 15 in the form of a grid may be added to the outer side of the cover 12 for protecting the speakers 120 and 121 and preventing dust and other debris from floating into the speaker structure 10. .

In the speaker structure 10 of the prior art, the two corresponding side walls 111 of the hollow casing 11 are linearly extended from the periphery of the opening 110 to the back side wall 112 in a tapered manner, and the main purpose thereof is The tympanic membrane of the woofer 120 generates an instantaneous vibration, and applies a backward pushing force to the gas in the hollow casing 11 (when the tympanic membrane of the woofer 120 is displaced backward), the hollow casing can be made The gas in the eleventh, the two side walls 111 which are designed to be tapered backwards in a straight line, flows backward, and causes the speaker to produce a low frequency resonance effect. The helium gas flows backward along the two side walls 111 which are tapered backward in a straight line, and after hitting the back side wall 112, the gas in the hollow casing 11 will rebound toward the opening 110 due to the characteristics of gas compression. Thus, the tympanic membrane vibration of the woofer 120 is adversely affected. Therefore, in order to avoid the foregoing problems, in the speaker structure 10, at least one or more bass reflex holes 122 are designed on the cover body 12 to smoothly pass the bounced gas through the bass reflex hole 122 to the outside. Shoot out.

Referring to FIG. 1 , although the design of the bass reflex hole 122 is designed on the cover 12, the rebounding gas in the hollow casing 11 can be avoided, and the tympanic membrane vibration of the woofer 120 is adversely affected. However, since the gas rebounded in the hollow casing 11 can be emitted only to the outside through the opening 110 on the front side of the hollow casing 11, a part of the gas can be emitted to the outside through the bass reflex hole 122. The remaining part will still generate unnecessary vibration to the cover 12, and negatively affect the tympanic vibration of the woofer 120, thereby causing a phenomenon of bass distortion; further, in the conventional speaker structure 10, due to all The sound waves are emitted to the outside by the opening 110 on the front side of the hollow casing 11. Therefore, the reflected sound waves and the sound waves directly emitted from the opening 110 without being reflected are mutually interfered, causing the beat frequency. The frequency of offsetting each other seriously degrades the sound quality of the playback, so that the sound quality of the speaker structure 10 in actual application is always difficult to make a significant breakthrough; in addition, since all sound waves are caused by the hollow shell The front side 11 of the exit opening 110 outwardly, significantly limiting the scope of sound transmission, this phenomenon also causes the speaker 10 of the conventional structure, in the use of difficult to achieve a good sound field effect.

In summary, it is known that the conventional speaker structure still has some defects in design, so that it is difficult to provide a very good sound field effect in practical applications. Therefore, how to design a speaker structure, in addition to avoiding the rebound of the gas in the hollow casing, negatively affecting the tympanic membrane vibration of the woofer, it is also possible to prevent all sound waves from being emitted from the same opening on the front side of the hollow casing. Causes the sound waves to cancel each other out, and degrades the sound quality of the playback. In addition, the sound can be transmitted to a wider range (ie, the space beyond the sound transmitted by the opening) in a multi-directional manner. Furthermore, it is possible to simulate an excellent and extremely accurate range or sound field effect, which is an important subject of the present invention.

In view of the above-mentioned many disadvantages of the conventional speaker structure, the inventor has finally developed a barrel-shaped multi-directional speaker structure of the present invention after repeated research and testing by virtue of his practical experience in serving related industries for many years.
