Problems solved by technology

[0009] However, since it is necessary to change the length of the extrusion force adjustment protrusion 14ca by changing the mold for the upper cap so as to change the length of the extrusion force adjustment protrusion, it is difficult to change the length of the extrusion force adjustment protrusion
Also, tuning is difficult as no suitable means exist for attenuating the high frequency sound of the membrane

Abstract

The present invention provides an intake sound generating apparatus which may include a tuning cap having a pressing force adjusting member, an upper cap having a predetermined length and detachably coupled to the tuning cap, a lower cap disposed under the upper cap and detachably coupled to the upper cap, and a membrane that is interposed and supported between the lower cap and the upper cap and pressed by the pressing force adjusting member of the tuning cap to generate sound while being vibrated by pulse pressure of air supplied to the lower cap.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2009-0119120 filed on December 3, 2009, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to an intake sound generator, and more particularly to an intake sound generator, which is realized using membrane vibration caused by intake pulsation in an intake port of a vehicle engine Sporty sound. Background technique [0004] In related fields, such as figure 1 As shown, the intake sound generator equipped in the vehicle includes a tuning pipe (tuning pipe) 13 and a horn 14. 12 is branched out, and a horn 14 is provided at the end of the tuning pipe 13 to generate sound. [0005] Such as figure 2 As shown, the horn 14 is composed of a lower cap 14a fitted on the end of the tuning pipe 13, a thin film 14b made of rubber to generate Sound, the upper cap 14c is c...
