FIELD: acoustics. SUBSTANCE: pressure gradient head has case, cover in the form of truncated cone, inertia element, piezoids of capacity C1 and C2 mounted on opposite sides of inertia element, reinforcing member in the form of stud made of material having Young's modulus of (19-21)1010 N/sq.m, one of its ends being fixed within case and other connected to cover through threaded joint. All these components are arranged coaxially. Head also incorporates four capacitors of values C11, C21, C12, C22, respectively, mounted in case. Case and cover are symmetrical to plane crossing center of inertia element perpendicular to heat axis. Ratio of height of cover side wall over generating line to its thickness is 8-9. Capacitors C11 and C12 are connected in parallel with piezoids and two other capacitors are connected to them in series. Capacitances are selected from equation
.
EFFECT: improved design. 1 dwg
