The invention relates to a device for switching sound tracks according to horizontal or vertical arrangement of a loudspeaker box. The device of the invention is a portable loudspeaker box accessory product which uses an integration design of a miniature loudspeaker monomer array, and in the method and device, the output positions of a left sound track and a right sound track are switched according to the horizontal or vertical arranging direction of the device, thereby ensuring that no matter the loudspeaker box accessory product is horizontally or vertically arranged by a user, the left sound track and the right sound track can output good sound for hearing.
Description
Technical field
The present invention proposes a kind of loudspeaker array audio amplifier placing direction anyhow of utilizing, and can carry out the method and apparatus that the left and right acoustic channels outgoing position switches.
Background technology
In recent years, along with the continuous development and progress of storage medium technology, built-in multimedia play-back technology, mp3, PMP (portable media player) product is used by everybody in a large number.Buy a mp3 or PMP equipment, use earphone cord, just can listen long music, watch the video of the small screen.Same mobile phone has also had the function of playing back music and video.
The portable audio frequency and video main process equipment of a part when supporting earpiece audio output, the function that also provides audio frequency to put outward, the user can use just listoning music easily of earphone.But because portable audio frequency and video main process equipment is all more portable small and exquisite, the boombox monomer of its use is little, the operatic tunes is little, power limited, and causing raising one's voice to its utmost outside self, sound is little, Hz-KHz is limited, tonequality is not good.
Use portable audio frequency and video main process equipment to obtain the demand that high-quality is put outward in order to satisfy the user, the custom-designed audio amplifier accessory product of portable audio frequency and video main process equipment occurred being.These audio amplifier accessory product configuration designs are bigger, and suitable operatic tunes size is arranged, and independent macrocell or power supply are powered, and can play the music of big volume, wideband sound scope, high tone quality.
Present known audio amplifier accessory product, stereo audio interface and the tone frequency channel wire that 3.5 cun or 2.5 cun only are provided that have, this all can be suitable for for most portable audio frequency and video main process equipment, and versatility is relatively good; But the shortcoming of this mode is audio amplifier accessory product and portable audio frequency and video main process equipment to link together by tone frequency channel wire, and globality is poor, uses inconvenient.
So audio amplifier accessory product occurred with the integrated design of portable audio frequency and video main process equipment.Portable audio frequency and video main process equipment can be embedded among the audio amplifier very easily, perhaps can be inserted in the slot of audio amplifier, and there are the connector of portable audio frequency and video main process equipment private definition or 3.5 cun/2.5 cun stereo audio interface in both contact positions.A lot of audio amplifier accessory product can be carried out special harmony design, good integrity according to the appearance characteristics of portable audio frequency and video main process equipment.
Most existing audio amplifier accessory product all can be used bigger loudspeaker monomer, and all more than 30mm, in order to reach good performance, operatic tunes volume is big for diameter, and power consumption is big, and power supply is powered or needed the polylith battery.The audio amplifier accessory product outward appearance that designs like this is bigger, not too meets portable requirement, carries very inconvenient.
The Microspeaker monomer array portable loudspeaker box product that the present invention uses, it is known equipment, put it briefly, be to use the loudspeaker monomer of diameter 16mm or 12mm, by the loudspeaker monomer array that a plurality of loudspeaker monomer devices are formed, reach the characteristics of small size, the little operatic tunes, low-power, big volume in audio amplifier.
Similarly, as Fig. 1, in the portable loudspeaker box accessory product of the integrated design of this use Microspeaker monomer array, portable audio frequency and video main process equipment can be embedded among the audio amplifier accessory product, and a plurality of Microspeaker monomers are positioned at four extensions of audio amplifier.The user might vertically place the audio amplifier accessory product when listening to the music, and also might laterally place; Can laterally or vertically switch the ground displaying video back and forth according to user's placement direction and the portable audio frequency and video main process equipment that video playback is provided has.
Under the situation as indicated above, just need a kind of method and apparatus, satisfy the sense of hearing demand of user left and right acoustic channels audio frequency outgoing position.Realize promptly no matter the audio amplifier accessory product is laterally to place or vertically place, and the loudspeaker monomer on the left side is always exported the L channel audio frequency, and the loudspeaker monomer on the right is always exported right audio channel.
Summary of the invention
Part or all of intention of the present invention and enforcement will be embodied in the following description, perhaps can obtain in specific embodiments.
The object of the present invention is to provide a kind of according to the audio amplifier method and apparatus of the changeable sound channel of placing direction anyhow.
For achieving the above object, the present invention uses the portable loudspeaker box accessory product of the integrated design of Microspeaker monomer array, utilize its placing direction anyhow, carry out the method and apparatus that the left and right acoustic channels outgoing position switches, guarantee the user when laterally or vertically putting the audio amplifier accessory product, good left and right acoustic channels output sense of hearing is all arranged.
Described Microspeaker monomer is diameter 16mm, 12mm or other acceptable small sizes; A plurality of Microspeaker monomers are formed loudspeaker monomer array, for example 4,8,12 or other acceptable numbers.Microspeaker monomer array has the characteristics of small size, the little operatic tunes, low-power, big volume, uses the audio amplifier accessory product of Microspeaker monomer array, can make smaller and more exquisitely, can meet portable requirement.
Described audio amplifier accessory product and portable audio frequency and video main process equipment are incorporate designs, portable audio frequency and video main process equipment is embedded in the middle of the audio amplifier accessory product, the connector of the local with good grounds portable audio frequency and video main process equipment private definition of both contacts or 3.5 cun/2.5 cun stereo audio interface pass to stereo audio signal in the audio amplifier accessory product from portable audio frequency and video main process equipment.
Described audio amplifier accessory product uses acceleration transducer to detect the horizontal or vertical placing direction of self.This is that judge to use at the inclination angle of acceleration transducer, and is special, and described acceleration transducer can be lower range (0～10G) the acceleration transducer of three or diaxon.
