Description

A kind of Novel outdoor speaker

Technical field

The utility model relates to speaker technology field, specially a kind of Novel outdoor speaker.

Background technique

Speaker refers to a kind of equipment that audio signal can be transformed to sound.Popular saying just refers to speaker host cabinet or low Power amplifier is carried in sound receiver body, audio signal is amplified, sound is played back out by speaker itself after handling, make its sound The change of tune is big.Speaker is the terminal of entire sound system, and effect is audio electric energy to be converted into corresponding sound energy, and it is radiated It is gone to space.It is the extremely important component part of sound system, is responsible for the ear that electric signal is transformed into acoustical signal for people Directly listening to for task.

The purpose why there is cabinet of speaker --- primarily to preventing the sound of diaphragm of loudspeaker obverse and reverse Wave signal is directly formed into a loop, and causes the high intermediate frequency sound of only wavelength very little that can propagate from, and other voice signals It is applied and balances out.The physical model of speaker is that a hole is opened on one block of infinitely great rigid baffle, installs loudspeaker, this Sample causes sound wave circuit it is ensured that the voice signal of loudspeaker obverse and reverse will not be formed into a loop.But in actual use, sound Case can not be made into infinity, and therefore, people form a closed space with baffle behind loudspeaker, guarantee sound wave Front transmission.Following problem: the problem of after speaker is closed due to atmospheric pressure, the cabinet of speaker is more big more is conducive to Low-frequency sound reduction, so, the volume of general speaker is that the speaker size of the bass unit in calculates a compromise Data.Can many environment still be not allow for too big cabinet, people are in order to further reduce volume, and according to the spy of sound wave Point and the requirement for reinforcing low-frequency sound wave playback devise baffle in case, phase-reversing tube, resonant cavity etc., primarily in low frequency band The voice signal of certain wavelength is enhanced, and is further reduced influence of the atmospheric pressure to sound-reducing.Loudspeaker is in sound Ringing in equipment is a most weak device, and for acoustics, it is a most important component again.Loudspeaker has A variety of sort-types: it is a variety of that electrodynamic type, electromagnetic type, piezoelectric type, digital etc. can be divided by its transposition mode；It can divide by diaphragm structure It is a variety of for single cone, compound cone, compound horn, coaxial etc.；Cone basin formula, ball top type, flat, band can be divided by vibrating diaphragm beginning Formula etc. is a variety of；High frequency, intermediate frequency, low frequency, ultralow frequency and full range speaker can be divided by frequency is reset；It can be divided by magnetic circuit form outer Magnetic-type, internal magnetization, double magnetic circuit formula and protected type etc. are a variety of；Ferrimagnet, neodymium boron magnet, alnico can be divided by magnetic circuit property Magnet loudspeaker；It can separation matter and non-cone loudspeaker etc. by diaphragm materials.

Speaker should not often be carried for outdoor technology also prematurity, speaker currently on the market at present and open air is damp It is wet, it be easy to cause the short circuit of speaker.
