Abstract: A baseball or softball bat having a sound generator disposed therein. A resilient member retains a knocker in relation to an inner surface of the bat when the sound generator is in an inactive, at-rest state. Upon an impact of the barrel with an object, the resilient member flexes or is deformed causing the knocker to strike an inner surface of the bat and generate a simulated bat impact sound.

Abstract: A multi-component baseball or softball bat has a vibration absorber affixed to an end of the handle. The vibration absorber has a first section disposed within an end of the barrel of the bat and a second section disposed outside of the barrel. An outer locking sleeve has a first portion disposed over an end of the barrel and a second portion disposed over the second section of the vibration absorber. A vibration sleeve may be disposed between the outer surface of the barrel and an inner surface of the first portion of the outer locking sleeve.

Abstract: A shock and vibration absorbing system includes a shock and vibration dampener disposed within a handle or tapered section of a bat. The dampener includes at least one elastomeric dampening element for supporting a mass in suspension within the bat without the mass contacting an inner surface of the bat. The dampening elements include a body having the mass extending therethrough and a plurality of spaced apart projections having distal ends in contact with an inner surface of the bat.

Abstract: A barrel of a baseball or softball bat is coupled to an end of a handle of the bat by means of a vibration absorber affixed to the end of the handle. Projections of a first locking section of the vibration absorber engage with depressions formed on an inner surface of the barrel. Adhesive disposed within gaps and channels of the vibration absorber adhere the vibration absorber to the barrel. A second locking section of the vibration absorber is attachable to a sleeve disposed over the handle. The sleeve may be of a material having shock absorbing or dissipating characteristics.
