Detailed description of the invention
Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model.
This utility model provides one to have phasing, the audio driver of waveguide and compression, see figures.1.and.2, in one embodiment, this audio driver includes T ferrum, frame, vibrating diaphragm, interior bugle, outer bugle and phase plug, described interior bugle is connected with T ferrum, described outer bugle is arranged in frame, described phase plug is arranged on interior bugle, in the space that outer bugle and vibrating diaphragm are formed, described interior bugle, outer bugle and phase plug are annular revolving body, described phase plug includes compressing surface, inner waveguide face and external wave guide face, described inner waveguide face and external wave guide face are all connected with compressing surface, described compressing surface is arranged towards vibrating diaphragm.
Principle: phase plug is set in the front of vibrating diaphragm, it is possible to improve the phase characteristic (diaphragm oscillations sound wave is had phasing effect) of audio driver voice output；The acoustic radiating mouth that interior bugle, outer bugle and phase plug form twice ring-type inside and outside narrow and small cavity and phase plug and outer bugle, interior bugle composition in vibrating diaphragm front, sectional area is less, to improve vibrating diaphragm equivalent radiated power impedance operationally, thus reaching to improve the electro-acoustic conversion efficiency of driver；Meanwhile, this phase plug and interior bugle, outer bugle form inside and outside twice acoustic waveguiding respectively, improve the wave surface of driver acoustic radiating, and then improve the radiation efficiency of sound.And inside and outside the formed acoustic radiating impedance of twice acoustic waveguiding, further improve the electro-acoustic conversion efficiency of audio driver.
Described T ferrum is provided with pore, and the space in described interior bugle connects with pore；The concrete structure that described interior bugle is connected with T ferrum can be: described pore is provided with female thread, and described interior bugle is externally provided with the external screw thread engaged with female thread.
In order to be beneficial to the propagation of sound, all can be horn-like in what extend out inside described annular revolving body；Further, the cross section of the outer waveguide that the cross section of the inner waveguide that described inner waveguide face is formed with interior bugle and external wave guide face become with nickname dihedral can be extend out horn-like.
Described inner waveguide face can be connected with external wave guide face, to reduce production difficulty, improves wave guiding effect.
In order to improve the transport properties of outer waveguide better, described external wave guide face is provided with waveguide ditch, described waveguide ditch is made up of two waveguide sides and a guide floor, described guide floor is connected with two waveguide sides, compressing surface and external wave guide face respectively, and described waveguide side is also connected with compressing surface, external wave guide face.Described waveguide side can be triangle or tetragon.
Described phase plug can be arranged in interior bugle and/or outer bugle and/or frame by support；When phase plug is provided with waveguide ditch, support can be connected in waveguide ditch and the frame of phase plug, so that the mounting structure of phase plug is stable；Above-mentioned support can not use the structure of annular revolving body, to prevent waveguide from cannot send；Support can be 2 or the connections above part, being evenly distributed on the annular acoustic radiating mouth of phase plug and interior bugle and/or phase plug and outer bugle and/or phase plug and frame, the connection between support with phase plug and/or interior bugle and/or outer bugle and/or frame can be bonding, welding, clamping etc..
For making the sound wave that audio driver produces comparatively be evenly distributed on direction, a face, putting shown in orientation such as Fig. 1, the top of outer bugle is higher than the top of interior bugle, and the top of interior bugle is higher than the top of phase plug.
