record that would be susceptible to vertical vibration at the resonance freqency of the record and accurate reproduction of the recorded signal is achieved furthermore any vibrations transmitted to the turntable 7 for example from the drive motor for the latter or as a result of impacts or shocks to which the cabinet of the record player may be subjected are absorbed or damped by the viscous liquid 4 in space 3 so that such vibrations are not transmited to the record and thence to cartridge 10 therefore cartridge 10 picks up only the signals actually recorded in the groove of phonograh record 9 and accurate reproduction of such signals is ensured it is further to be noted that the sloping arrangement of the edge portions 1c and 1d of upper wall 1a which define the outer and inner peripheral walls of annular space 3 ensures that such peripheral walls can be easily flexed downwardly when required to achieve uniform contact with the undersurface of a warped phonograph record placed on mat 1 thus in the case of a phonograph record having its outer peripheral portion warped upwardly as on fig3 the sloping arrangement of the inner edge portion 1d of upper wall 1a is easily deformed downwardly to permit full contact of upper wall 1a with the undersurface of the warped record rather than contacting the latter primarily at the inner edge of wall 1a as indicated.
