Abstract
The utility model relates to a reflective high-directivity loudspeaker, which comprises a reflector, a driver, a reflecting tube, a reflecting tube support, an inner tube, a reflector regulating device, an inner tube regulating device and a sleeve, wherein the reflecting tube is fixed with the reflecting tube support, the reflecting tube support is fixed with one end of the inner tube, the other end of the inner tube is fixed with the inner tube regulating device, one end of the inner tube regulating device is connected with the reflector regulating device, the reflector regulating device is fixed with the reflector, the reflector is fixed with the sleeve, and the other end of the inner tube regulating device is connected with the driver. The reflective high-directivity loudspeaker has the advantages of increasing efficiency of a loudspeaker system, acquiring higher sound pressure, utilizing space and material more effectively, having higher directivity, achieving higher sound pressure in a forward direction of sound transmission and reducing sound wave scattering to the surrounding by adding the sleeve. To sum up, the reflective high-directivity loudspeaker is simple in structure, far in sound transmission distance, high in expansion, simple in process and adjustable in directivity, and can be widely applied to horn loudspeakers with high requirements upon directivity and performance.
Description
Technical field
The utility model relates to a kind of loud speaker, particularly a kind of reflective highly directive loud speaker that is used for high pitch horn speaker fields such as radar Acoustic antenna, highly directive loud speaker or bicycle-mounted portable formula Acoustic antenna.
Background technology
Along with the development of portable sound reinforcement system and popularize, market is all the more strong to the horn loudspeaker demand that power is big, in light weight, volume is little, price is low, highly sensitive.Lower, the whole assembly technology complexity of horn performance, the directive property of like product are unadjustable at present.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides a kind of reflective highly directive loud speaker.Reached that the sharp-pointed degree, the directive property that increase directive property are adjustable, expansion is convenient in system, be convenient to target such as assembling.
The utility model for achieving the above object, the technical scheme of being taked is: a kind of reflective highly directive loud speaker, comprise reflector, driver, it is characterized in that: also comprise reflection tube, the reflection tube support, interior pipe, reflector adjusting device and interior pipe adjusting device, described reflection tube and described reflection tube support are fixed, reflection tube support and described interior Guan Yiduan fix, the interior pipe other end and described interior pipe adjusting device are fixed, interior pipe adjustable pipe one end is connected with described reflector adjusting device, reflector adjusting device and described reflector are fixed, and the interior pipe adjusting device other end is connected with driver.
A kind of reflective highly directive loud speaker, comprise reflector, driver, it is characterized in that: also comprise reflection tube, the reflection tube support, interior pipe, reflector adjusting device and interior pipe adjusting device and bustle pipe, described reflection tube and described reflection tube support are fixed, reflection tube support and described interior Guan Yiduan fix, the interior pipe other end and interior pipe adjusting device are fixed, pipe adjusting device one end is connected with described reflector adjusting device in described, reflector adjusting device and described reflector are fixed, reflector and described bustle pipe are fixed, and the interior pipe adjusting device other end is connected with driver.
The beneficial effects of the utility model are: 1, adopt reflective horn structure, in limited space, increased the length of horn, thereby increased the efficient of speaker system, thereby obtain higher acoustic pressure.In addition, adopt reflective horn structure, itself has also taken into account the effect of certain supporting construction interior pipe, has more effectively utilized space and material.
2, adopt the camber reflection body, sound wave is adjusted to approximate plane wave, because the characteristic of plane wave itself makes the sound wave of regulating by reflection have stronger directive property, and then reaches higher acoustic pressure in the positive direction of sound transmission by reflection.
3, by pipe adjusting device and reflector adjusting device in adopting, the position of reflective horn can be regulated.In order further to improve the sharp-pointed degree of directive property, increased and enclosed tube, enclose tube by increase simultaneously, can reduce the peripherad diffusion of sound wave.In a word, simple in structure, have the transfer voice distance, autgmentability is strong, technology is easy, the adjustable characteristics of directive property, can be widely used in directive property, performance are had the horn speaker of strict demand.
