Abstract
The utility model discloses a kind of audio amplifier with passive passive radiator, this audio amplifier with passive passive radiator comprises: a casing and be installed on the active loud speaker of casing lower end, described casing lower end is provided with one as the ring of passive passive radiator, and be connected with active loud speaker by this ring, wherein, inner side and the active loud speaker outer rim of ring are fixed, and along fixing in the outside of ring and casing lower end, make in casing and form a seal cavity; Described active loud speaker is as the vibrating diaphragm of ring.In the middle part of described ring, lower surface forms outwardly for strengthening flexible projecting ring section.The utility model utilizes active loud speaker as the vibrating diaphragm of passive passive radiator to save space, the bass effect that can obtain when smaller size smaller, so that the utility model has the higher market competitiveness.
Description
Technical field:
The utility model relates to speaker products technical field, refers in particular to a kind of audio amplifier with passive passive radiator, and this audio amplifier utilizes active loud speaker as the vibrating diaphragm of passive passive radiator to save space, the bass effect that can obtain when smaller size smaller.
Background technology:
The sound equipment of " passive radiator " is used usually to comprise initiatively loudspeaker unit and a passive unit (passive radiator).Loudspeaker unit profile is similar usually and initiatively for passive unit, but does not have voice coil loudspeaker voice coil and drive magnet.It only has a cone, and get along well any voice coil loudspeaker voice coil or circuit are connected.Passive radiator is usually used to adjust bass, makes designer can regulate the tone color of audio amplifier entirety.Passive radiator active cell in audio amplifier carries out passive sounding under the drive of air in casing.
Usual use passive radiator replace phase-reversing tube be all in order to regulate compared with small box tonequality and make it have better bass performance.Especially in some cases, be not suitable for because casing is too little installing phase-reversing tube, passive radiator is exactly a good replacement scheme.It is also used for eliminating the disturbance of casing air-flow and the compression to loudspeaker unit stroke alleviated caused by the high-speed motion of air-flow in phase-reversing tube usually.
Utility model content:
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of audio amplifier with passive passive radiator is provided, this audio amplifier utilizes active loud speaker as the vibrating diaphragm of passive passive radiator to save space, the bass effect that can obtain when smaller size smaller.
In order to solve the problems of the technologies described above, the utility model have employed following technical proposals: this audio amplifier with passive passive radiator comprises: a casing and be installed on the active loud speaker of casing lower end, described casing lower end is provided with one as the ring of passive passive radiator, and be connected with active loud speaker by this ring, wherein, inner side and the active loud speaker outer rim of ring are fixed, and along fixing in the outside of ring and casing lower end, make in casing and form a seal cavity; Described active loud speaker is as the vibrating diaphragm of ring.
Furthermore, in technique scheme, in the middle part of described ring, lower surface forms outwardly for strengthening flexible projecting ring section.
Furthermore, in technique scheme, the described projecting ring section that described ring comprises ring inner edge, ring outer rim and is connected between ring inner edge and ring outer rim, wherein, ring inner edge and ring outer rim are parallel to each other, and ring inner edge is higher than ring outer rim.
Furthermore, in technique scheme, described ring and active loud speaker concentric.
Furthermore, in technique scheme, inner edge, described casing lower end is provided with an annular mounting groove, and described ring outer rim outer rim is fixed in this annular mounting groove.
Furthermore, in technique scheme, described casing cylindrically.
After adopting technique scheme, the utility model has following beneficial effect compared with prior art: the utility model utilizes active loud speaker as the vibrating diaphragm of passive passive radiator to save space, the bass effect that can obtain when smaller size smaller, thus the utility model has the higher market competitiveness.
Accompanying drawing illustrates:

Fig. 2 is cutaway view of the present utility model;
Fig. 3 is three-dimensional exploded view of the present utility model;
Fig. 4 is the installation diagram of ring and active loud speaker in the utility model.
Embodiment:
Below in conjunction with specific embodiments and the drawings, the utility model is further illustrated.
See shown in Fig. 1-4, be a kind of audio amplifier with passive passive radiator, it comprises: a casing 1 and be installed on the active loud speaker 2 of casing 1 lower end and the ring 3 as passive passive radiator.
Cylindrically, and described ring 3 and active loud speaker 2 concentric, active loud speaker 2 is typical circular loud speaker to described casing 1.
Described casing 1 lower end is connected with active loud speaker 2 by this ring 3, and wherein, inner side and active loud speaker 2 outer rim of ring 3 are fixed, and along fixing in the outside of ring 3 and casing 1 lower end, makes in casing 1 and forms a seal cavity; Described active loud speaker 2 is as the vibrating diaphragm of ring 3, and that is, active loud speaker 2 vibrates with ring 3 and vibrates.
In the middle part of described ring 3, lower surface forms outwardly for strengthening flexible projecting ring section 31.Specifically, described ring 3 comprises ring inner edge 32, ring outer rim 33 and is connected to the described projecting ring section 31 between ring inner edge 32 and ring outer rim 33, wherein, ring inner edge 32 and ring outer rim 33 are parallel to each other, and ring inner edge 32 is higher than ring outer rim 33.
Inner edge, described casing 1 lower end is provided with an annular mounting groove 11, and described ring outer rim 33 outer rim is fixed in this annular mounting groove 11.
The utility model utilizes active loud speaker as the vibrating diaphragm of passive passive radiator to save space, the bass effect that can obtain when smaller size smaller, so that the utility model has the higher market competitiveness.
Certainly, the foregoing is only specific embodiment of the utility model, be not limit the utility model practical range, all equivalences done according to structure, feature and principle described in the utility model claim change or modify, and all should be included in the utility model claim.
