A kind of Combined sound systemTechnical field
A kind of Combined sound system, relates to electroacoustic field, is related specifically to a kind of Combined sound product with Bluetooth data transfer function.
Background technology
The development of sound technique has been achieved for a lot of achievements, fast-developing and whole audio frequency industrial chain perfect along with Internet technology in recent years, traditional sound technique product becomes increasingly abundant, and the change cycle of new product is also very fast, personal consumption level sound equipment common currently on the market divides kind mainly to be had: Bluetooth audio device, plug-in card sounding, WIFI sound equipment, motion sound equipment, domestic acoustics etc.; The composition of product is distinguished, mainly includes: single loudspeaker stereo, sound equipment 2.0, sound equipment 2.1 etc.; From these sound equipments, come into numerous brand acoustic products in market except difference in appearance, functionally there is no too big difference, they maximum features be exactly use be all based on DYN dynamic acoustic technique, loudspeaker send sound Dou Shi omnidirectional propagates, when we use this type of stereo set to listen music time, it is possible to because surrounding enviroment are caused noise jamming by its omnidirectional's sounding, and can be likely to have influence on other people around.
Currently more advanced directional audio product adopts parametric array technology to develop, its feature is by a kind of signal processing algorithm the sound finally sending a kind of orientable propagation in conjunction with a kind of supersonic changer element or piezoelectric film material, related content is referred to the paper " Farfieldperformanceofparametrictransmitters " delivered by H.O.Berktay, the product adopting this technological development not only has the feature of direction propagation sound, and its audio sending sound has very strong telepresenc, the sound that it sends sounds pure, press close to, clearly, the diverse auditory perception of audience can be given. but the current cost developing a set of this product is also higher.
This Combined sound system disclosed in this patent, the design concept of this integrated form not only largely enriches acoustic product function, and reduces the cost of two stand-alone products of exploitation generally. It can provide the play mode that omnidirectional is two kinds different with directed sounding, not only make consumer can enjoy the sound listening tradition acoustic product, the different-effect that directional audio brings can also be experienced in case of need, so can meet consumer's diversified demand in varied situations.
Summary of the invention
It is an object of the invention to provide a sound system being integrated with directional audio module and conventional omnidirectional audio module, so that acoustic product can not only have the transaudient feature of overall space, and have the function that local space is transaudient concurrently, this enriches the function of sound equipment to a great extent, under the premise meeting audience's conventional requirement, also an independent audio space can be provided to audience, the problem that so can avoid the noise jamming because sound leakage causes and secret audio leakage.
For realizing object above, this patent is achieved through the following technical solutions:
The support base of Combined sound, it is provided to whole sound system and supports and have the fixing function put, and is also the linking part of rotary connecting device.
The rotary connecting device of horizontal 360-degree, by designing, at bracket base, the rotation that tumbler regulates the horizontal direction of speaker, what this was rotationally connected that part adopts is, and a kind of spring assembly makes ball roll and is stuck in the mode of groove horizontally rotates.
The part that is rotationally connected of vertical direction is to adopt the fixing axle of one to constitute with twisting solid knob, the sensing of speaker can be made to be fixed on a position of a vertical direction by turning knob.
Speaker module is to be raised one's voice sounding module by orientation and omnidirectional's speaker module is constituted, the array that wherein directed speaker module is made up of the supersonic changer element of more than 1, it is alternatively the panel of raising one's voice that PVDF or EMFi piezoelectric membrane is made, omnidirectional's sounding module is made up of omnidirectional's loudspeaker of 1 omnidirectional's loudspeaker or more than 2, directed speaker module and omnidirectional's speaker module are separately fixed at diverse location or the direction of speaker module, and two modules are connected to two outfans of core control panel by electric wiring.
Hardcore control circuit is for controlling the work of machine system, audio frequency input can be connected by Bluetooth audio frequency or tone frequency channel wire and provide source of sound, after audio signal processes system respectively through two sound passage entrance and does different Audio Processing, the final port assignment at processor goes out directional audio signal output port and omnidirectional audio signal output port, the two outfan is each electrically coupled to directed speaker module and omnidirectional's speaker module, and core control circuit has source of sound switching, time-out, volume adjusting function.
Combined sound disclosed by the invention has omnidirectional and directed loud-speaking function concurrently, not only largely enriches acoustic product function, meets the different consumers different demands to acoustic function, and reduces the cost of two stand-alone products of exploitation generally; Speaker module is in the design-adjustable of level Yu vertical direction, and the use making directed beep pattern is more flexible; Orientation is raised one's voice under mode of operation, makes secret audio-frequency information to reveal, and sound is thrown in local will not form the interference to surrounding enviroment.
