Abstract
The utility model discloses a micro loudspeaker with a passive radiator. The micro loudspeaker comprises a hollow housing, a main loudspeaker disposed in the housing and the passive radiator disposed in the housing, and is characterized in that the main loudspeaker is interconnected with the passive radiator through an enclosed cavity, one side surface of the housing is provided with a main sound outlet and an auxiliary sound outlet, the main sound outlet is communicated with the main loudspeaker, and the auxiliary sound outlet is communicated with the passive radiator. Sounding directions of the passive radiator and the main loudspeaker are consistent due to the fact that sound guiding tubes are disposed in the micro loudspeaker, and low-frequency extension effect is reinforced.
Description
Technical field
the utility model relates to the loud speaker field, particularly a kind of Microspeaker with passive radiator.
Background technology
in general loud speaker, the voice directions of main loudspeaker and passive radiator is same direction, so when by main loudspeaker, promoting air, again by the passive radiator of air push, can make loud speaker reach the effect that low frequency extends, but again in Microspeaker, the space of leaving passive radiator for is also very little, present is compressed because of the Microspeaker structure, cause passive radiator and can't make itself and main loudspeaker be on same plane, therefore passive radiator voice directions and main loudspeaker voice directions do not have homophase, therefore the sound low-frequency effect is not good.
Summary of the invention
the purpose of this utility model is to provide a kind of passive radiator voice directions Microspeaker identical with the main loudspeaker sounding
for achieving the above object, the technical solution adopted in the utility model is: a kind of Microspeaker with passive radiator, it comprises the housing of hollow, be arranged on the main loudspeaker in described housing, be arranged on the passive radiator in described housing, described main loudspeaker is communicated with by airtight cavity with described passive radiator, a side of described housing is provided with main outlet sound mouth and secondary outlet sound mouth, described main outlet sound mouth communicates with described main loudspeaker, described secondary outlet sound mouth communicates with described passive radiator, because the voice directions of passive radiator and main loudspeaker is consistent, can better strengthen the low frequency extension effect.
preferably, described main outlet sound mouth communicates by the first sound guide tube with described main loudspeaker, described secondary outlet sound mouth communicates by the second sound guide tube with described passive radiator, between described the first sound guide tube, described the second sound guide tube, described cavity, be provided with can sound insulation barricade, barricade can prevent the sound interference between each position and then promote speaker voice giving efficiency.
preferably, described housing comprises upper cover and lower cover.
because technique scheme is used, the utility model compared with prior art has following advantages:
due to the utility model, by sound guide tube is set, make the voice directions of passive radiator and main loudspeaker consistent, strengthen the low frequency extension effect; By the setting of barricade, can prevent the sound interference between each position and then promote speaker voice giving efficiency.
The accompanying drawing explanation
accompanying drawing 1 is schematic diagram of the present utility model;
accompanying drawing 2 removes the schematic diagram after upper cover for the utility model;
accompanying drawing 3 is schematic diagram of the present utility model.
in above accompanying drawing: 1, upper cover; 2, lower cover; 3, main loudspeaker; 4, passive radiator; 5, cavity; 6, the second sound guide tube; 7, main outlet sound mouth; 8, secondary outlet sound mouth; 9, barricade; 10, the first sound guide tube.
Embodiment
below in conjunction with embodiment shown in the drawings, the utility model is further described:
embodiment mono-: shown in accompanying drawing 1-3, a kind of Microspeaker with passive radiator, it comprises the housing of the hollow that upper cover 1 and lower cover 2 form, be arranged on the main loudspeaker 3 in described housing, be arranged on the passive radiator 4 in described housing, described main loudspeaker 3 is communicated with by airtight cavity with described passive radiator 4, a side of described housing is provided with main outlet sound mouth 7 and secondary outlet sound mouth 8, described main outlet sound mouth 7 communicates with described main loudspeaker 3, described secondary outlet sound mouth 8 communicates with described passive radiator 4, described main outlet sound mouth 7 communicates by the first sound guide tube 10 with described main loudspeaker 3, described secondary outlet sound mouth 8 communicates by the second sound guide tube 6 with described passive radiator 4, described the first sound guide tube, described the second sound guide tube 7, between described cavity 5, be provided with can sound insulation barricade 9.
above-described embodiment is only explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection range of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection range of the present utility model.
