Related Art

[0002] Nowadays, due to progress of computer technology and internet, much audio and video broadcasting is realized on the computer via the internet. Therefore, many peripheral multimedia apparatuses are highly needed, and more and more high-level speakers are sold, which are 2.0, 5.1 or 7.1 sound channels speakers. Nevertheless, the performances of such 5.1 or 7.1 sound channels speakers are not always needed in any time. That is, in case of phoning internet call, it merely needs single sound channel or dual sound channels speakers, but in case of watching TV/movie or playing electronic games, the single sound channel or dual sound channels speakers should be switched to 5.1 or 7.1 sound channels speakers correspondingly. Even though many speakers capable of switching different sound channels are sold, but a press button is still needed specially to control the different sound channels switching.

[0003] Please refer to Japan published patent no. 2006/033077. The speaker unit comprises a body having a wireless communication section for transmitting acoustic signals of a plurality of channels outputted from a sound source section to speakers corresponding to respective channels while converting them into wireless signals, and a plurality of speakers outputting the wireless signals received from the body section while converting them into voice signals. The body comprises a speaker arrangement position determining section generating arrangement information indicative of the arranging position of each speaker detected with reference to the arranging position of a center speaker, and a section for generating channel set information assigning the channel of acoustic information corresponding to the arranging position of each speaker indicated by the arrangement information wherein the wireless communication section transmits the channel of the acoustic signal to each speaker based on the channel set information.

[0004] Please also refer to US issued patent no. 4,151,470. An acoustic apparatus comprising a detachable combination of a stereophonic radio set and monaural tape recorder is disclosed. The tape recorder operates as a monaural element when decoupled from the stereophonic radio but includes a stereophonic head which cooperates with stereophonic elements in the stereophonic radio to produce a stereophonic output when the tape recorder and radio are coupled together.

[0005] However, the different sound channels are unable to be switched rapidly by utilizing the press button. Therefore, this disclosure discloses a multiple channel speaker system which switches different sound channels rapidly and instinct to overcome the prior art defect.

BRIEF DESCRIPTION OF THE DRAWINGS

[0010] This disclosure can be more fully understood by referring to the following detailed description and examples with references made to the accompanying drawings, wherein:

Fig.1a and 1b is the schematic diagram of a preferred embodiment of a multiple channel speaker system according to this disclosure.

Fig.2a and 2b is the schematic diagram of another embodiment of a multiple channel speaker system according to this disclosure.

DETAIL DESCRIPTION OF THE INVENTION

[0011] The following description is of the best-contemplated mode of carrying out this disclosure. This description is made for the purpose of illustrating the general principles of this disclosure and should not be taken in a limiting sense. The scope of this disclosure is best determined by reference to the appended claims.

[0012] Fig.1a is the schematic diagram of a preferred embodiment of a multiple channel speaker system according to this disclosure. As shown in Fig.1a, the multiple channel speaker system 100 is an integrally multiple channel speaker system 100, which essentially comprises a first speaker 102, at least one second speaker 104, a plurality of sensing switches 106 and an audio decoder 108. The first speaker 102 is adjacent to the second speaker 104, and the first speaker 102 is wired connected to the second speaker 104, or the first speaker 102 is wirelessly connected to the second speaker 104. The sensing switch 106 is disposed between the first speaker 102 and the second speaker 104, wherein the sensing switch 106 is a mechanical trigger device or a touched sensing device, and to be emphasized is that this disclosure is not limited to the disclosed embodiments. The audio decoder (Audio Codec IC) 108, electrically connected to the sensing switch 106, is used for judging switching condition of the sound channels by means of receiving an output signal form the sensing switch 106. Generally, the first speaker 102 and the second speaker 104 are connected together to form a single sound channel or dual sound channels speaker. As shown in Fig.1b, when the first speaker 102 is separated from the second speaker 104, the sensing switch 106, disposed between the first speaker 102 and the second speaker 104, outputs a signal to the audio decoder 108. Therefore, the audio decoder 108 switches the multiple channel speaker system 100 from a single sound channel or dual sound channels speaker to a 2.1 sound channels speaker, and switches the two second speakers 104 to left and right sound channels speakers respectively, and further switches the first speaker 102 to a low-sounding speaker.

[0013] Fig.2a is the schematic diagram of another embodiment of a multiple channel speaker system according to this disclosure. As shown in Fig.2A, the multiple channel speaker system 200 essentially comprises at least one first speaker 202, at least one second speaker 204, at least one third speaker 206, a plurality of sensing switches 208 and an audio decoder 210. The first speaker 202 is adjacent to the second speaker 204, and the second speaker 204 is adjacent to the third speaker 206, hence the first speaker 202, the second speaker 204 and the third speaker 206 are wired connected or wirelessly connected to each other. For instance, the wireless transmitted technologies include but not limited to infrared wireless transmission or blue tooth wireless transmission. The sensing switches 208 are disposed between the first speaker 202 and the second speaker 204, and between the second speaker 204 and the third speaker 206 respectively, wherein the sensing switches 208 are mechanical trigger devices or touched sensing devices, and to be emphasized is that this disclosure is not limited to the disclosed embodiments. The audio decoder 210, electrically connected to the sensing switches 208, is used for judging switching condition of the sound channels by means of receiving output signals form the sensing switches 208. Generally, the first speaker 202, the second speaker 204 and the third speaker 206 are connected together. Besides, when the second speaker 204 is separated from the third speaker 206, the sensing switch 208, disposed between the second speaker 204 and the third speaker 206, outputs a signal to the audio decoder 210. Therefore, the audio decoder 210 switches the multiple channel speaker system 200 from a single sound channel or dual sound channels speaker to a 2.1 sound channels speaker, and switches two third speakers 206 to left and right sound channels speakers respectively, and further switches the first speaker 202 and second speaker 204 to low- sounding speakers.

[0014] In addition, as shown in Fig.2B, when the second speaker 204 is separated from the first speaker 202, the sensing switch 208, disposed between the first speaker 202 and the second speaker 204, also outputs a signal to the audio decoder 210. Thus, the multiple channel speaker system 200 switches from a 2.1 to 5.0 sound channels speaker, wherein the first speaker 202 is the main sound channel speaker, the second speakers 204 are the left-front and right-front sound channels speakers, and the third speakers 206 are the left-rear and right-rear sound channels speakers correspondingly. Accordingly, when the above mentioned speakers are separated from each other, the sensing switches 208, disposed among those speakers, drive the audio decoder 210 to switch sound channels correspondingly, so as to use no any press button. In detail, the above mentioned embodiments of this disclosure does not limit to merely switch a single sound channel speaker to a 2.1 or 5.0 sound channels speaker, said single sound channel or dual sound channels speakers can be further switched to 2.0, 5.0 or 7.1 sound channels speakers by adding or removing the speakers correspondingly. On the other hand, the switching sequence of those speakers is to separate the first speaker 202 from the second speaker 204 first, then separate the second speaker 204 from the third speaker 206, such that the purpose of switching a dual channel speaker system to a multiple channel speaker system could be achieved on the same way.

[0015] In sum, one of the objectives of this disclosure can be achieved to switch sound channels directly and instinct when said speakers are separated from each other by means of the sensing switches, which is convenient and efficient because it is not necessary for the user to switch the sound channels by utilizing a manual switch.

[0016] While the invention has been described by way of example and in terms of the preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments. To the contrary, it is intended to cover various modifications and similar arrangements. Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
