Abstract
The utility model discloses a household subwoofer. The household subwoofer comprises a box body (1) and at least one loudspeaker (2), wherein a sound channel (3) is arranged inside the box body (1); the loudspeaker (2) is arranged inside the sound channel (3); the household subwoofer further comprises a plurality of passive radiating devices; the passive radiating devices are arranged inside the sound channel at the two sides of the loudspeaker (2); and the sounding directions of passive radiating devices are consistent with the sounding direction of the loudspeaker (2). The household subwoofer is small in volume and can sound a subwoof.
Description
Technical field
The utility model relates to family expenses subwoofer audio amplifier manufacturing technology field, specifically is a kind of family expenses subwoofer audio amplifier.
Background technology
Subsonic bass effect has much relations with the size of loud speaker.Present on the market a lot of and television set, supporting audio amplifier (SoundBar) dimensional requirement such as computer is all very little, and bass effect is difficult to show.Can only increase a subwoofer in order to improve this situation, but, therefore will inevitably influence the installing space of television set, computer again and effect is installed because the volume ratio of subwoofer is bigger.Therefore, for these reasons, demand urgently needing a kind of volume little and can send the family expenses subwoofer audio amplifier of subwoofer effect again, to address the above problem.
The utility model content
The technical problem that the utility model will solve is, overcomes the defective of above prior art, provides a kind of volume little and can send the family expenses subwoofer audio amplifier of subwoofer effect again.
The technical scheme of the utility model is, a kind of family expenses subwoofer audio amplifier is provided, and comprises casing and at least one loud speaker, is provided with sound channel in the described casing; Described loud speaker is installed in the sound channel, and described family expenses subwoofer audio amplifier also comprises a plurality of passive radiation devices, and described a plurality of passive radiation devices all are located in the sound channel of loud speaker both sides; The pronunciation of said a plurality of passive radiation devices towards with the pronunciation of loud speaker towards consistent.
Described passive radiation device comprises basin frame, oscillating plate and dust cap, and a side of described oscillating plate is connected with the basin frame, and the opposite side of said oscillating plate is connected with dust cap.
The quantity of described loud speaker is two, and the pronunciation of said two loud speakers is towards unanimity.
After adopting above structure, the utility model compared with prior art has the following advantages:
The utility model family expenses subwoofer audio amplifier; Be to reach and increase oscillating mass and should rate send the subwoofer effect with the minimum resonance that reduces casing through a plurality of passive radiation devices (being false loudspeaker) are installed in the loud speaker front; Owing to need not to increase the volume of loud speaker; Therefore guaranteed that the volume of whole family expenses subwoofer audio amplifier is less, but can utilize a plurality of passive radiation devices to send the subwoofer effect, therefore guaranteed the installing space of television set, computer and effect is installed.
Description of drawings
Fig. 1 is the structural representation of the utility model family expenses subwoofer audio amplifier.
Fig. 2 is the enlarged diagram of A portion among Fig. 1.
Shown in the figure 1, casing, 2, loud speaker, 3, sound channel, 4, the basin frame, 5, oscillating plate, 6, dust cap.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
Like Fig. 1, shown in Figure 2, a kind of family expenses subwoofer of the utility model audio amplifier comprises casing 1 and at least one loud speaker 2, is provided with sound channel 3 in the described casing 1; Described loud speaker 2 is installed in the sound channel 3, and described family expenses subwoofer audio amplifier also comprises a plurality of passive radiation devices, and described a plurality of passive radiation devices all are located in the sound channel of loud speaker 2 both sides; The pronunciation of said a plurality of passive radiation devices towards with the pronunciation of loud speaker 2 towards consistent; Be the passive radiation device dust cap towards with the dust cap of loud speaker 2 towards consistent, just the dust cap of the dust cap 6 of passive radiation device and loud speaker 2 be not relative direction, neither be rightabout.The structure of loud speaker 2 is prior aries, like Fig. 1, shown in Figure 2, is not just detailing at this.
Described passive radiation device comprises basin frame 4, oscillating plate 5 and dust cap 6; One side of described oscillating plate 5 is connected with basin frame 4; The opposite side of said oscillating plate 5 is connected with dust cap 6, and described passive radiation device just removes remaining structure behind loud speaker 2 magnetic structures.
The quantity of described loud speaker 2 is two, and the pronunciation of said two loud speakers 2 is towards unanimity, and promptly the dust cap of two loud speakers 2 is towards being consistent, just the dust cap of two loud speakers 2 be not relative direction, neither be rightabout.
Below only be described, but can not be interpreted as it is restriction claim with regard to the most preferred embodiment of the utility model.The utility model is not limited only to above embodiment, and its concrete structure allows variation.In every case the various variations of in the protection range of the utility model independent claims, being done are all in the protection range at the utility model.
