Embodiment Construction

[0014] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0015] see figure 2 The sectional view shown in the passive radiator speaker system provided by the present invention comprises a speaker unit 2 and a passive radiator unit 3, and the speaker unit 2 and the passive radiator unit 3 are coaxially installed, that is, the speaker unit 2 It is arranged in the frame 34 of the passive passive radiator unit 3 (different from the parallel arrangement in the prior art). The loudspeaker unit 2 includes a basin frame 22 (which coincides with the central axis of the basin frame 34), a diaphragm 20 arranged on the basin frame 22 through a positioning support p...

Abstract

The invention provides a passive radiator loudspeaker system, which comprises a loudspeaker unit and a passive radiator unit, wherein the loudspeaker unit and the passive radiator unit are mounted coaxially. The loudspeaker unit and the passive radiator unit of the passive radiator loudspeaker system adopt a coaxial mode for sound production so that the phase difference of two unit sounds can be avoided effectively; besides, because the loudspeaker unit and the passive radiator unit are mounted in the coaxial mode, the mounting area of a box body of a sound box can be saved so that the box body of the sound box can be miniaturized to save the space.

Description

technical field [0001] The invention relates to the field of loudspeakers, in particular to a passive radiator loudspeaker system. Background technique [0002] Passive radiator speaker (also known as empty paper cone speaker, affect paper cone speaker) is a sound reproduction system developed on the basis of inverted speakers. It is composed of a speaker unit and a passive radiator unit (commonly known as empty Paper cone), the passive radiator unit replaces the position of the inverter tube of the inverted speaker, the working principle of the passive radiator speaker is to use the spring action of the air in the box after the vibration of the speaker paper cone to vibrate the empty paper cone, It forms resonance with the speaker, and the basic working principle is similar to that of the vented speaker. Such as figure 1 As shown in , most of the existing passive radiator loudspeaker (speaker box) systems install the loudspeaker unit 10 and the passive radiator unit 11 se...
