Fig. 1 is the structural schematic diagram of the sounding device shown in an exemplary embodiment of the invention, as shown in Figure 1, of the invention There is provided a kind of sounding device, comprising: at least two loudspeakers 1;At least two loudspeakers 1 be tweeter, mid frequency ludspeaker, The combination of two or more any loudspeaker in middle/high frequency loudspeaker or woofer;Loudspeaker 1 is arranged in sounding On the shell 2 of device, the front 11 of loudspeaker is towards the outside of shell 2, and the back side 12 of loudspeaker is towards the inside of shell 2;? At least one sound outlet hole 3 is offered on shell 2 between each loudspeaker 1;On the inner wall of the housing, apart from each sound outlet hole 3 It is provided in preset range backwards to leading note plate 4;It is fixedly connected backwards to one end of leading note plate 41 with the inner wall of shell 2, backwards to leading note The other end of plate is free end 42, with guide loudspeaker 1 backwards to sound wave along the extending direction backwards to leading note plate 4 to loudspeaker 1 mobile backwards and around leading note plate backwards free end 42 is pierced by by sound outlet hole 3.
It should be noted that the sounding device in the present invention can be applied to any hair with structure described in the invention In acoustic device, for example, the sounding device (speaker or loudspeaker) integrated in independent speaker, terminal, earphone, in following embodiments all It is illustrated with the structure example of speaker.Specifically, the diaphragm of loudspeaker is when vibrating respectively to forward direction and sending sound backwards Wave, this two-way acoustic wave " phase " are opposite.So-called " phase " is any moment of diaphragm oscillations displacement on the contrary, above-mentioned two-way acoustic wave Waveform cancels each other out just, to cause vibrating diaphragm two-way acoustic wave that " short circuit " phenomenon occurs in the sky.The sound of naked loudspeaker is often Shrivelled, overcautious, narrow, here it is the concrete embodiments of sound " short circuit ".And the birth of speaker, essence will play loudspeaker Efficiency, it is theoretical that design principle is based on " infinite baffle ", that is, by diaphragm of loudspeaker forward direction and, theory isolated from one another backwards to sound wave Model is to place a piece of infinite baffle between diaphragm of loudspeaker forward direction and backwards sound wave, and using positive sound wave, partition is backwards to sound Wave.But infinitely great baffle has no practical possibility, and infinite baffle is then carried out convolution shape backwards to sound wave direction to loudspeaker At a confined space, here it is the theoretical basis of modern speaker design.
Modern speaker is roughly divided into three classes, closed box, bass reflex type, transmission wire type;It is closed box to pass through confined air Between completely cut off loudspeaker completely backwards to the propagation of sound wave;Bass reflex type (being called inverted phase type) speaker is using loudspeaker backwards to sound wave Cabinet wall multipath reflection and form oscillation wave, and reinforce the bass effect of speaker by the resonance effect of phase-reversing tube. But should be also the sound wave of full range backwards to sound wave if loudspeaker is full frequency speaker, but this work of phase inverted cabinet Make mode but to inhibit backwards to sound wave, and resonance wave output will be converted to backwards to sound wave, only highlights low-frequency sound wave, and The integrality backwards to the carried audio signal of sound wave is destroyed simultaneously;Transmission wire type is called labyrinth type speaker, by speaker The tortuous passageway that one bore constantly reduces and fill sound-absorbing object is set, constantly slackens loudspeaker backwards to the energy of sound wave, thus Obtain preferable low frequency response.It can be seen that no matter the design of any speaker, be all based on the diaphragm of loudspeaker can be shielded backwards to sound or Inhibit the sound wave backwards of loudspeaker, therefore there is a problem that the electroacoustic energy conversion efficiency of loudspeaker is low.When speaker operation, Vibrating diaphragm equably forward, issue sound wave energy backward, and according to infinite baffle theory, positive sound wave is effective energy, and backwards to sound Wave is invalid harmful energy, and positive sound wave can use, must then inhibit backwards to sound wave.Theoretically infer, the electricity of speaker Sound transfer efficiency can not be more than 50%.For reality, the electro-acoustic conversion efficiency of rare speaker can reach 20%.Electroacoustic turns The direct performance for changing low efficiency is that narrow Hz-KHz, frequency response and signals revivification are inferior.
