Abstract
The utility model relates to a twin loudspeaker, which comprises an outer tube, a rear magnetic circuit panel mounted in the inner cavity of the tail section, a magnetic loop, an outer pole shoes, an inner pole palm, a vibrating membrane, a voice coil and a master acoustic horn comprising a reflection acoustic duct tube mounted in the inner cavity of the fore part, an interior acoustic duct tube and a positive vibratory cavity. The utility model is characterized in that the tail section of the master acoustic horn passes through a voice tube 10 and is provided with an auxiliary acoustic horn back to back, which can effectively enlarge broadcasting range.
Description
The utility model relates to a kind of broadcasting equipment, particularly relates to a kind of Twin loudspeaker.
Traditional Horn loudspeaker also claims loudspeaker, by the nickname pipe, be contained in the back magnetic circuit plate of its afterbody inner chamber, magnet ring, the outer utmost point palm, inner polar palm, vibrating membrane and voice coil loudspeaker voice coil, be contained in the reflected sound deferent of its anterior inner chamber, interior sound conduit tube and forward vibration cavity are formed, because back magnetic circuit plate and inner polar palm are round pie, like this, only can partly export by the acoustic energy that voice coil loudspeaker voice coil produced from the nickname pipe, voice coil loudspeaker voice coil is toward the energy of after vibration, and then the air of enclosing because of voice coil loudspeaker voice coil is when voice coil loudspeaker voice coil vibrates, and air is compressed and expands energy dissipation has been fallen.
The purpose of this utility model is to provide a kind of Twin loudspeaker that effectively utilizes the acoustic energy of former and later two directions of voice coil loudspeaker voice coil and then enlarge the broadcast scope.
The purpose of this utility model is to realize like this, that is: this Twin loudspeaker, comprise by the nickname pipe, be contained in back magnetic circuit plate, magnet ring, the outer utmost point palm, inner polar palm, vibrating membrane and the voice coil loudspeaker voice coil of its afterbody inner chamber, be contained in the main loudspeaker that the reflected sound deferent of its anterior inner chamber, interior sound conduit tube and forward vibration cavity are formed, its key is: at main loudspeaker afterbody, by voice tube is back-to-back secondary loudspeaker are housed.
Described secondary loudspeaker are made of nickname pipe, reflected sound deferent, interior sound conduit tube and bonnet.
Described back magnetic circuit plate and inner polar palm are equipped with a hole for sound wave output.
The utility model compared with prior art because the sound wave that voice coil loudspeaker voice coil produces can be from two nickname pipes outputs of installing back-to-back, the broadcast scope that is doubled, acoustic efficiency doubles.
Accompanying drawing is a general structure schematic diagram of the present utility model.
Hereinafter with reference to accompanying drawing concrete structure of the present utility model is further described.
Referring to accompanying drawing, the utility model Twin loudspeaker, by nickname pipe 5, be contained in back magnetic circuit plate 1, magnet ring 2, the outer utmost point palm 3, inner polar palm 9, vibrating membrane and the voice coil loudspeaker voice coil 4 of its afterbody inner chamber, be contained in main loudspeaker and secondary loudspeaker of installing back-to-back by voice tube 10 and main loudspeaker of reflected sound deferent 6, interior sound conduit tube 7 and forward vibration cavity 8 compositions of its anterior inner chamber.Described secondary loudspeaker are made of nickname pipe 5, reflected sound deferent 6, interior sound conduit tube 7 and bonnet 11.The axial line of major and minor loudspeaker both can be same axis, also can bend certain angle to adapt to the needs of different occasions by voice tube.In addition,, only need be folded down voice tube and secondary loudspeaker, install a lid additional at main loudspeaker afterbody and promptly constitute traditional Horn loudspeaker in occasion that must not two-way broadcast.It is convenient to have the dress folding, uses flexibly practical characteristics.
Claims (3)
1, a kind of Twin loudspeaker, comprise by the nickname pipe, be contained in back magnetic circuit plate, magnet ring, the outer utmost point palm, inner polar palm, vibrating membrane and the voice coil loudspeaker voice coil of its afterbody inner chamber, be contained in the main loudspeaker that the reflected sound deferent of its anterior inner chamber, interior sound conduit tube and forward vibration cavity are formed, it is characterized in that: by voice tube (10) is back-to-back secondary loudspeaker are housed at main loudspeaker afterbody.
2, according to the described Twin loudspeaker of claim 1, it is characterized in that: secondary loudspeaker are by nickname pipe (5), and reflected sound deferent (6), interior sound conduit tube (7) and bonnet (11) constitute.
