Abstract
The utility model discloses separable 2.1-channel digital sound equipment. The digital sound equipment comprises two satellite box bodies, a subwoofer host and a power adapter; after the two satellite box bodies are connected together in series through an audio line, an output end is jointly led out and connected to a standard stereo plug; besides, the two satellite box bodies are further connected with a USB (universal serial bus) power supply connecting joint; a synchronous volume amplitude output interface used for being connected with the stereo plug of the satellite box bodies and a USB interface used for being connected with the USB power supply connecting joint of the satellite box bodies are correspondingly arranged on the subwoofer host; the two satellite box bodies and the subwoofer hose can be combined and used as the 2.1-channel sound equipment; and the two satellite box bodies can also be independently used as 2.0-channel sound equipment. The satellite box bodies and the subwoofer host can be detached and combined, so that the use is convenient.
Description
Technical field
The utility model belongs to the sound technique field, relates in particular to a kind of 2.1 sound channel digital acousticses.
Background technology
Along with the development of multimedia audio-video equipment such as notebook computer, mp3, mp4, stereo mobile phone, the development of miniature digital acoustics is very rapid.More popular miniature digital acoustics is mainly 2.0 and 2.1 sound channel digital acousticses at present.2.1 the sound channel sound equipment can better satisfy the requirement of user for tonequality, but portable not enough with respect to 2.0 sound channel digital acousticses.The user need a not only can be at the stereo set of working under 2.0 patterns but also can under 2.1 patterns, work.
The utility model content
At the deficiencies in the prior art, the purpose of this utility model is to provide a kind of detachable 2.1 sound channel digital acousticses, and solving same set of stereo set not only can be in the problem of working under 2.0 patterns but also can work under 2.1 patterns.
For achieving the above object, the utility model adopts following technical scheme:
A kind of detachable 2.1 sound channel digital acousticses, comprise two satellite casings, a subwoofer main frame and a power supply adaptor, draw an output jointly after described two satellite casings are serially connected by tone frequency channel wire and be connected on the standard stereo plug; Described two satellite casings also are connected with a USB power supply connector; Described subwoofer main frame correspondingly is provided with a sync tone discharge amplitude output interface, is used to connect the stereo plug of satellite casing; Described subwoofer main frame correspondingly is provided with USB interface, is used to connect the USB power supply connector of satellite casing; Described subwoofer main frame is provided with a stereo input interface and connects external sound source equipment or earphone by tone frequency channel wire.
The USB power supply interface of described subwoofer main frame has two.
Described subwoofer main frame is provided with SD interface or FM audio signal reception device.
The interface of described power supply adaptor power output end is a USB interface.
Described audiogenic device comprises desktop computer or notebook or MP3 player or stereo mobile phone.
Described two satellite casings, one of them has power amplifier.
The beneficial effect that the utility model produces:
Use detachable 2.1 sound channel digital acousticses described in the utility model, be applicable to multimedia equipments such as desktop computer, notebook, MP3 player, stereo mobile phone, the satellite casing can take apart independent use from the subwoofer main frame, satisfied user's multiple suitable requirement.
Description of drawings
Fig. 1 is that 2.1 sound channels of the present utility model constitute and connection layout.
Embodiment:
As shown in Figure 1, the utility model mainly comprises band power amplifier satellite casing 1, is not with power amplifier satellite casing 2, the main frame 3 and the power supply adaptor 6 of band subwoofer.Draw an output jointly after satellite casing 1,2 is serially connected by tone frequency channel wire and be connected on the standard stereo plug 4, and any one is drawn a power line and is connected on their common USB power supply connectors 5 in satellite casing 1,2.There is an adaptor power supplies interface lower left, subwoofer main frame 3 upper end, by adapter the USB power output interface of power supply adaptor 6 is transferred into the circuit output interface, connect by circuit then, subwoofer main frame 3 and power supply adaptor 6 are linked together, realized the power supply of 6 pairs of subwoofer main frames 3 of power supply adaptor, subwoofer main frame upper end middle position has two to be the USB power supply interface of arranging up and down 7,8 simultaneously, connect the USB power supply connector 5 of satellite casing 1,2, be mainly used in to satellite casing 1,2 and power.And also have two audio signal interfaces 9,10 in the lower right of subwoofer main frame 3 upper ends, audio signal interface 9 is a sync tone discharge amplitude output interface, the stereo plug 4 that connects satellite casing 1,2, mainly audio signal is sent on the satellite casing 1,2, and realizes the synchronizing function of the audio signal of satellite casing 1,2 and subwoofer main frame 3; Audio signal interface 10 is stereo input interface, connects the external sound source equipment by tone frequency channel wire 11, as desktop computer, and notebook, MP3, stereo mobile phone or be connected to and listen to music signal on the earphone.In addition, the subwoofer main frame also has SD interface and FM audio signal reception device.The FM audio signal reception device need not the said external referenced device and does input, directly detects radio signals and plays the radio station broadcast signal that subwoofer main frame 3 receives by subwoofer main frame 3 and satellite casing 1,2 again.
In addition, band power amplifier satellite casing 1,2 can independently use and constitute 2.0 sound channel public address, can cooperate subwoofer main frame 3 to make up 2.1 sound channel public address again.And therefore subwoofer main frame 3 can not independently use because built-in loudspeaker unit is a bass unit, must just can use constituting under the situation of 2.1 sound channels with satellite casing 1,2, and embodiment is as indicated above.And satellite casing 1,2 uses the execution mode that constitutes 2.0 sound channels to have separately:
1, satellite casing 1,2 and notebook: in this case, because power supply adaptor is contained in the notebook computer the inside, so only the common USB power supply of satellite casing 1,2 connectors 5 need be connected on the USB interface of notebook computer and just can obtain the electric weight supply, and the earphone output that the standard stereo plug 4 of satellite casing 1,2 is connected to notebook computer obtained audio signal from notebook computer, just can realize 2.0 sound channel public address.The volume of satellite casing 1,2 is controlled by notebook computer.
2, satellite casing 1,2 and stereo mobile phone: because the use of stereo mobile phone is storage battery, can not directly power to satellite casing 1,2, so satellite casing 1,2 must be powered with power supply adaptor 6, concrete operation method is the USB interface that satellite casing 1,2 common USB power supply connectors 5 is connected to power supply adaptor 6, and the standard stereo plug 4 of satellite casing 1,2 is connected to the handset earphone output obtains audio signal from stereo mobile phone, just can realize 2.0 sound channel public address.The volume of satellite casing 1,2 is controlled by stereo mobile phone.
3, satellite casing 1,2 and MP3 player: the same with stereo mobile phone, the MP3 player all is to adopt battery to power, therefore can not be directly to satellite casing 1,2 be powered, so satellite casing 1,2 must be powered with power supply adaptor 6, concrete operation method is the USB interface that the common USB power supply of satellite casing 1,2 connectors 5 is connected to power supply adaptor 6, thereby and will and the standard stereo plug 4 of satellite casing 1,2 be connected to the audio signal that MP3 earphone output obtains from the MP3 player and realize 2.0 sound channel public address.The volume of satellite casing 1,2 is controlled by the MP3 player.
