Abstract
The invention discloses a loudspeaker. The loudspeaker comprises a housing body with accommodation space and a loudspeaker single body accommodated in the housing body. The loudspeaker also comprises sound absorbing materials arranged in the housing body. The sound absorbing materials comprise a zeolite molecular sieve. The skeleton structure of the zeolite molecular sieve comprises silicon elements, iron elements and aluminum elements. According to the invention, tone quality of a product can be improved.
Description
Technical field
The present invention relates to acoustic-electric conversion art, be specifically related to a kind of speaker.
Background technology
Along with the fast development of electronic information technology, increasing electronics applications to speaker as its sound-generating element, for instance mobile phone, notebook computer etc..Nowadays, the acoustical behavior of described speaker is had higher requirement by people.The speaker of related art construction mainly includes housing and the microphone device being contained in described housing, in order to improve tonequality, common practice is to fill the sound-absorbing material of such as zeolite molecular sieve etc in described housing, but the framing structure of zeolite or molecular sieve is mainly made up of silicon or sial, nitrogen in air is had very big absorbability by it, and for the limited sorption capacity of the oxygen in air, make the low frequency performance that zeolite or molecular sieve show not high, to the limited use improving speaker tonequality.
Therefore, it is necessary to described speaker is further improved, to improve the acoustical behavior of speaker.
Summary of the invention
It is an object of the invention to solve the deficiency of sound-absorbing material in above-mentioned speaker, and the speaker that a kind of low frequency performance is good, tonequality is good is provided.
Speaker provided by the invention, it housing including tool receiving space and the loudspeaker monomer being contained in described housing, described speaker also includes the sound-absorbing material being located in described housing, described sound-absorbing material comprises zeolite molecular sieve, and comprises element silicon, ferrum element and aluminium element in the framing structure of described zeolite molecular sieve.
Preferably, the silicon in the framing structure of described zeolite molecular sieve/(ferrum+aluminum) atomic ratio is more than 100.
Preferably, housing is divided into ante-chamber and back cavity by described loudspeaker monomer, and described loudspeaker monomer is placed in ante-chamber and is in communication with the outside, and described sound-absorbing material is placed in back cavity.
A kind of speaker, it housing including tool receiving space and the loudspeaker monomer being contained in described housing, described speaker also includes the sound-absorbing material being located in described housing, described sound-absorbing material comprises zeolite molecular sieve, and the framing structure of described zeolite molecular sieve comprises element silicon and ferrum element, do not comprise aluminium element.
Preferably, the silicon in the framing structure of described zeolite molecular sieve/iron atom ratio is more than 100.
Preferably, described housing includes ante-chamber and back cavity, and described loudspeaker monomer is placed in ante-chamber and is in communication with the outside, and described sound-absorbing material is placed in back cavity.
The beneficial effects of the present invention is: speaker provided by the invention, it by arranging the sound-absorbing material comprising zeolite molecular sieve in housing, and aluminum portions in the framing structure of described zeolite molecular sieve or all replace with ferrum, on the one hand, the effect of expansion operatic tunes volume can be played, on the other hand, the introducing of ferrum is conducive to improving the zeolite molecular sieve absorption to oxygen, simultaneously without influence on the absorption to nitrogen, described speaker is made to show better low frequency performance, its Integral low-frequency frequency reduces, the sound pressure level of low frequency part increases, thus significantly improving the tonequality of described speaker, and adopt zeolite molecular sieve as sound-absorbing material, its volume is little can put into less cavity, can solve the problem that the little problem being difficult to encapsulation sound-absorbing material of the speaker operatic tunes.
Accompanying drawing explanation
Fig. 1 is the structural representation of speaker provided by the invention.
Detailed description of the invention
Below the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, all other embodiments that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
As shown in Figure 1, speaker 100 for the present invention, it housing 101 including tool receiving space 10 and the loudspeaker monomer 1 being contained in described housing 101, described speaker 100 also includes the sound-absorbing material 2 being located in described housing 101, concrete, housing is divided into ante-chamber 11 and back cavity 21 by described loudspeaker monomer 1, and described loudspeaker monomer 1 is placed in ante-chamber 11 and is in communication with the outside, and described sound-absorbing material 2 is placed in back cavity 21.
In the present embodiment, described sound-absorbing material 2 comprises zeolite molecular sieve, and comprises element silicon, ferrum element and aluminium element in the framing structure of described zeolite molecular sieve.In the speaker 100 of the present invention, by the aluminium element partial replacement in the framing structure in zeolite molecular sieve for having magnetic ferrum element, the introducing of ferrum is conducive to improving the zeolite absorption on oxygen without affecting nitrogen adsorption, so that zeolite shows better low frequency strengthens performance.It addition, silicon/(ferrum+aluminum) atomic ratio in the framing structure of described zeolite molecular sieve is preferably greater than 100.
In other is implemented, aluminium element in framing structure in zeolite molecular sieve all can also be alternatively had the ferrum element of magnetic, namely, framing structure in zeolite molecular sieve comprises element silicon and ferrum element, but do not comprise aluminium element, and the silicon in the framing structure of zeolite molecular sieve/iron atom ratio is more than 100, the equally possible performance playing low frequency enhancing.
Described sound-absorbing material 2 can be zeolite molecular sieve powder, it is also possible to be zeolitic molecular sieve particle, and it is located in described housing 1 mainly through filling mode.Adopting zeolite molecular sieve as sound-absorbing material, its volume is little can put into less cavity, not by the restriction of encapsulation volume, it is possible to solve the little problem being difficult to encapsulation sound-absorbing material of the speaker operatic tunes.
Speaker 100 provided by the invention by arranging the sound-absorbing material 2 comprising zeolite molecular sieve in housing 101, and aluminum portions in the framing structure of described zeolite molecular sieve or all replace with ferrum, on the one hand, the effect of expansion operatic tunes volume can be played, on the other hand, the introducing of ferrum is conducive to improving zeolite and the molecular sieve absorption to oxygen, simultaneously without influence on the absorption to nitrogen, described speaker 100 is made to show better low frequency performance, its Integral low-frequency frequency reduces, the sound pressure level of low frequency part increases, thus significantly improving the tonequality of described speaker 100, and adopt zeolite or molecular sieve as sound absorber materials and parts, its volume is little can put into less cavity, can solve the problem that the little problem being difficult to encapsulation sound-absorbing part of the speaker operatic tunes.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the present invention and accompanying drawing content to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, all in like manner include in the scope of patent protection of the present invention.
