Abstract
The invention relates to the field of loudspeakers and specifically relates to a miniature loudspeaker and particularly relates to a loudspeaker which is provided with a virtual sound cavity and great in low-frequency effect. The loudspeaker provided with the virtual sound cavity includes a casing of the loudspeaker. A cavity is formed in the casing. The surface of the casing is provided with a sound output opening. A position of the casing, at the sound output opening, is connected with a sound generating assembly of the loudspeaker. The loudspeaker is characterized in that an air storing material capable of making the air stay inside for a specific time is arranged in the cavity. The loudspeaker with the virtual sound cavity is capable of reducing effectively a resonance frequency of the loudspeaker and improving a low-frequency sound pressure of the loud speaker without changing a structure or size so that a tone-quality effect of the loudspeaker is improved and tone-quality requirements of people are met.
Description
Technical field
The invention belongs to the loud speaker field, particularly a kind of Microspeaker, especially a kind of have virtual sound chamber, a loud speaker that low-frequency effect is good.
Background technology
The space of existing mobile phone, panel computer, notebook computer inside is more and more less, the space of leaving loud speaker for is also more and more less, caused the frequency range of acoustic pressure curve of the loud speaker of existing notebook, mobile phone and panel computer can't extend to low frequency, the king-rod of low frequency can't be reappeared sense of hearing, the requirement of consumer to sound quality can't be met.
Summary of the invention
For above-mentioned technical problem, the present invention has designed a kind of in the situation that not change structure and volume, can effectively reduce the resonance frequency of loud speaker, improves the low-frequency sound pressure of loud speaker, has improved the acoustical quality of loud speaker, meets the requirement of people to tonequality.
Realize that technical scheme of the present invention is as follows:
Loud speaker with virtual sound chamber, it comprises the housing of loud speaker, enclosure interior forms a cavity, the surface of housing is provided with sound mouth, be connected with the pronunciation component of loud speaker on the housing at sound mouth place, it is characterized in that: be provided with in described cavity and can make the gas storage material of air at the internal stops certain hour.
Described inside cavity is filled with the gas storage material fully.
Described gas storage material is divided into the first cavity and the second cavity by the space in cavity, when the gas storage material is divided into the first cavity and the second cavity by the space of cavity, the pronunciation component vibration, adopt the interior air of cavity by the first cavity process gas storage material, being docked to the second cavity, turn back to the first cavity by the second cavity again
Described gas storage material is Graphene, the density effect of Graphene, for cellular structure, during air molecule process grapheme material, can be in the internal stops regular hour of grapheme material, discharge again, be equivalent to increase in inside, sound chamber the amount of air, realized that little space becomes large space.
In sum, the present invention has following beneficial effect:
The gas storage material that the present invention arranges by the inside at loud speaker, the gas storage material is Graphene, the density of Graphene is little, and be cellular laminated structure, during air molecule process grapheme material, can be in the internal stops regular hour of grapheme material, discharge again, be equivalent to increase the air capacity of inside, sound chamber, realized the virtual change large space in little space, the increase of the air capacity after loud speaker in the sound chamber can be conducive to the work of pronunciation component, reduced the resonance frequency of loud speaker, improved the low-frequency sound pressure of loud speaker, the frequency range of Microspeaker and the acoustical quality of loud speaker have been improved, meet the requirement of people to product tonequality.
The accompanying drawing explanation
The structural representation that Fig. 1 is execution mode one;
The structural representation that Fig. 2 is execution mode two;
The structural representation that Fig. 3 is execution mode three;
The experimental data figure of the resonance frequency that Fig. 4 is the present invention's loud speaker of surveying;
In figure, 1 is housing, and 2 is pronunciation component, and 3 is cavity, and 4 is the gas storage material, and 5 is the first cavity, and 6 is the second cavity.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
Execution mode one
The loud speaker with virtual sound chamber as shown in Figure 1, it comprises the housing 1 of loud speaker, a cavity 3 of housing 1 inner formation, the surface of housing is provided with sound mouth, be connected with the pronunciation component of loud speaker on the housing at sound mouth place, pronunciation component 2 is tightly connected with housing 1, makes to form in housing the rear sound chamber of a sealing, is provided with in described cavity 3 and can makes the gas storage material 4 of air at the internal stops certain hour.
In present embodiment, inside cavity has been partially filled the gas storage material, in the present invention, adopt Graphene as the gas storage material, air can stop the regular hour in Graphene, realized in same cavity space having stored more air capacity, the increase of air capacity is conducive to the vibration of pronunciation component, can effectively reduce the vibration frequency of pronunciation component, improve the low-frequency sound pressure of loud speaker, improve the tonequality of Microspeaker, met the requirement of people to the tonequality of mobile phone, panel computer class mobile product.
Execution mode two
The loud speaker with virtual sound chamber as shown in Figure 2, it comprises the housing 1 of loud speaker, a cavity 3 of housing 1 inner formation, the surface of housing 1 is provided with sound mouth, be connected with the pronunciation component 2 of loud speaker on the housing at sound mouth place, be provided with in described cavity 3 and can make the gas storage material 4 of air at the internal stops certain hour.
Cavity 3 inside described in present embodiment are filled with gas storage material 4 fully.
Execution mode three
The loud speaker with virtual sound chamber as shown in Figure 3, it comprises the housing 1 of loud speaker, a cavity 3 of housing 1 inner formation, the surface of housing 1 is provided with sound mouth, be connected with the pronunciation component 2 of loud speaker on the housing at sound mouth place, be provided with in described cavity 3 and can make the gas storage material 4 of air at the internal stops certain hour.
Gas storage material described in present embodiment is divided into the first cavity 5 and the second cavity 6 by the space in cavity 3, when the gas storage material is divided into the first cavity and the second cavity by the space of cavity, the pronunciation component vibration, air in cavity is by the first cavity process gas storage material, being docked to the second cavity, turn back to the first cavity by the second cavity again, air has a cyclic process in chamber, the vibration of pronunciation component occurs in the first cavity, the amount of space of the first cavity is limited, but in the second cavity, circulate through Graphene through the air in the first cavity, realized the extension of the first cavity, improved air capacity, reduced the resonance frequency of loud speaker, improved the tonequality of loud speaker.
Gas storage material described in the present invention is Graphene, the density effect of Graphene, for cellular structure, during air molecule process grapheme material, can be in the internal stops regular hour of grapheme material, discharge again, be equivalent to increase in inside, sound chamber the amount of air, realized that little space becomes large space.
The present invention is not limited to described embodiment, and those skilled in the art, not breaking away from spirit of the present invention openly in scope, still can do some corrections or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
