BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention generally relates to a surround acoustic box system; in particular, it relates to a surround acoustic box system enabling speaker detachments in order to achieve desired surround channel effects.

2. Description of Related Art

As the world advances in every aspects, acoustic equipments have now become a sort of entertainment tools comprehensively applied in human daily lives. Also, in recent years, thanks to significant progresses and breakthrough in computer technologies, computers and acoustic apparatuses can be far better combined than before, thus allowing computer users to improvise various applications in conjunction with such acoustic devices, accordingly further facilitating the popularity thereof.

In order to completely express a variety of sounds through the acoustic apparatuses, the acoustic host can be enabled to output several channels and a corresponding number of speakers can be configured such that a speaker deals with the output of a specific channel. Hence so-called “surround acoustic equipments” featuring 4 channels, 5 channels, 5.1 channels and 7.1 channels etc. have been developed and come out. With more speakers, greater number of original channels can be presented.

Lately, people further proposed certain designs and technologies concerning single-unit surround acoustic apparatuses, which essentially focuses on using the sound bouncing back from the wall to let the outputted sounds achieve the effects provided by the conventional multi-pieced surround acoustic apparatuses; however, due to differences in terms of application environments, the efficiency of such a sound bouncing approach may vary; on the other hand, integrating all of the speakers into a single entity may not allow the user to autonomously construct the intended speaker combination and desired sound field effects.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Other technical contents, aspects and effects in relation to the present invention can be clearly appreciated through the detailed descriptions concerning the preferred embodiments of the present invention in conjunction with the appended drawings.

Refer first toFIGS. 1A-1D and 2A, wherein an overall architecture diagram, an architecture diagram for the first separable acoustic box, an architecture diagram for the second separable acoustic box, an architecture diagram for the host acoustic box body of the surround acoustic box system and overall structure diagram for the surround acoustic box system according to the present invention are respectively shown, and the illustrated surround acoustic box system comprises at least a first separable acoustic box1, at least a second separable acoustic box2, a host acoustic box body3and a bass speaker acoustic box4.

As shown inFIG. 1B, the first separable acoustic box1includes at least a first positioning connection part11, at least a first charging connection part12and a wireless transmission circuit module15, in which it is possible to input the electric power required by the first separable acoustic box1via the first charging connection part12, and on the forward surface13of the first separable acoustic box1there installs at least a forward speaker unit131for providing forward channels, and also on the upward surface14of the first separable acoustic box1there further obliquely installs at least an upward speaker unit141for providing upward channels; moreover, the wireless transmission circuit module15can be utilized to receive and transfer wireless signals.

Similarly, as shown inFIG. 1C, the second separable acoustic box2includes at least a second positioning connection part21, at least a second charging connection part22and a wireless transmission circuit module25, in which it is possible to input the electric power required by the second separable acoustic box2via the second charging connection part22, and on the forward surface23of the second separable acoustic box2there installs at least a forward speaker unit231for providing forward channels, and also on the upward surface24of the second separable acoustic box2there further obliquely installs at least an upward speaker unit241for providing upward channels; moreover, the wireless transmission circuit module25can be utilized to receive and transfer wireless signals.

Furthermore, as shown inFIG. 1D, herein the host acoustic box body3is a bar-like acoustic box and comprises a console circuit module31, a power supply circuit module32, a front speaker set331installed on the forward surface33, a top speaker set341obliquely installed on the upward surface34, a wireless transmission circuit module35, at least a first positioning sensor part361, at least a first power supply output part362, at least a second positioning sensor part371and at least a second power supply output part372.

Herein the console circuit module31controls the operations of the host acoustic box body3and is able to perform wireless signal transmissions with the wireless transmission circuit module15in the first separable acoustic box1as well as the wireless transmission circuit module25in the second separable acoustic box2by way of the wireless transmission circuit module35, and the power supply circuit module32is electrically connected to the console circuit module31thereby providing electric power required by the host acoustic box body3.

In order to facilitate the attachment of the first separable acoustic box1and the second separable acoustic box2to the host acoustic box body3, a combination baseboard36,37can respectively extend from each of the two sides on the host acoustic box body3, in which the first separable acoustic box1can be adjoined onto the combination baseboard36while the second separable acoustic box2adjoined onto the combination baseboard37, respectively.

Moreover, the first positioning sensor part361is installed on the combination baseboard36and electrically connected to the console circuit module31and the power supply circuit module32, in which the first positioning connection part11in the first separable acoustic box1is connected to the first positioning connection part361such that the console circuit module31can verify and confirm the attachment of the first separable acoustic box1onto the host acoustic box body3.

Analogously, the second positioning sensor part371is installed on the combination baseboard37and electrically connected to the console circuit module31and the power supply circuit module32, in which the second positioning connection part21in the second separable acoustic box2is connected to the second positioning connection part371such that the console circuit module31can verify and confirm the attachment of the second separable acoustic box2onto the host acoustic box body3.

Besides, the first charging connection part12may be a contact endpoint or a USB port; in case it is a contact endpoint, as shown inFIG. 2B, since the first power supply output part362is installed on the combination baseboard36, after adjoining the first separable acoustic box1onto the combination baseboard36, the first power supply output part362can output electric power to the first charging connection part12in the first separable acoustic box1; on the other hand, if the first charging connection part12is a USB port, then the first power supply output part362needs not to be installed on the combination baseboard36, but contrarily, as shown inFIG. 2C, it is possible to directly connect the first charging connection part12of the USB port to a power line6having a USB plug for supplying electric power.

In order to achieve the precise engagement between the first charging connection part12and the first power supply output part362, the bottom of the first separable acoustic box1is further installed with a first positioning frame bar16capable of encompassing the first positioning connection part11(if the first charging connection12is a contact endpoint, the first positioning frame bar16can also encompass the first charging connection part12), and the host acoustic box body3further includes a first positioning frame hole363corresponding to the first positioning frame bar16, and the first positioning frame hole363can at least encompass the first positioning sensor part361, in which the first positioning frame bar16can be inserted into the first positioning frame hole363such that the first positioning connection part11can then be precisely connected to the first positioning sensor part361(in case that the first charging connection part12is a contact endpoint, the first positioning frame bar16can also make the first charging connection part12electrically connect to the first power supply output part362precisely.)

In addition to the aforementioned structure, the first separable acoustic box1further includes a first frame17and the host acoustic box body3further has a first groove364corresponding to the first frame14, in which, after inserting the first frame17into the first groove364, the first positioning connection part11can be precisely connected to the first positioning sensor part361(suppose the first charging connection part12is a contact endpoint, the first frame17can also let the first charging connection part12electrically connect to the first power supply output part362precisely.)

Herein the first positioning frame bar16may be installed in a tilted fashion (e.g., on the slant towards left side) and the first positioning frame hole363may be located correspondingly to the first positioning frame bar16(e.g., also on the slant towards left side), while the installation position of the second separable acoustic box2encompassing the second positioning frame hole of the second positioning sensor part371may be otherwise oblique to the other side (e.g., towards right side), thus preventing potential installation errors such as erroneously inserting the second separable acoustic box2configured on the left side into the first positioning frame hole363.

It should be noticed that the second charging connection part22may be also a contact endpoint or a USB port, and since the structure thereof is the same as the first charging connection part12, its figure and illustrations are herein omitted for brevity; moreover, the combination structure formed by the second separable acoustic box2and the combination baseboard37is identical to the one formed by the first separable acoustic box1and the combination baseboard36, so its figure and illustrations are herein omitted accordingly for brevity as well.

Additionally, as shown inFIG. 1B, the inside of the first separable acoustic box1further includes a first charging battery18electrically connected to the first charging connection part12(herein the first charging battery18may be a lithium battery or other types of charging batteries), so it is possible to charge the first charging battery18by way of the first charging connection part12; in case the first separable acoustic box1is separated from the host acoustic box body3, the first charging connection part12can provide electric power required by the first separable acoustic box1by means of the first charging battery18without charging power. Similarly, as shown inFIG. 1C, the inside of the second separable acoustic box2further includes a second charging battery26electrically connected to the second charging connection part22, so it is possible to charge the second charging battery26by way of the second charging connection part22; hence, in case the second separable acoustic box2is separated from the host acoustic box body3, the second charging connection part22can provide electric power required by the second separable acoustic box2by means of the second charging battery26without charging power.

The front speaker set331includes four front speaker units3311,3312,3313and3314(or two front speaker units3313and3314), and such front speaker units3311,3312,3313and3314are respectively and electrically connected to the console circuit module31and the power supply circuit module32thereby outputting to provide the right channel effects, left channel effects and central straight channel effects.
