Need to trigger something when hit, without the objects moving

Unity Engine

Hi guys , heres my current script to cause objects to play a sound when hit , but i need to fix something so nether the object or the object hiting it move in anyway on the collision .

var myClip : AudioClip;
var explosionPrefab : GameObject ;

function OnCollisionEnter(collision : Collision) {
    // Debug-draw all contact points and normals
    for (var contact : ContactPoint in collision.contacts) {
        Debug.DrawRay(contact.point, contact.normal, Color.white);
    }
    
    // Play a sound if the coliding objects had a big impact.        
    //if (collision.relativeVelocity.magnitude > 0)
       audio.PlayOneShot(myClip);
       Debug.log("ok");
}

I’ve tried deleting rig bodies, but when i do that, the sound doesn’t play when hit .

Could one of your colliders be turned into a trigger, with an OnTriggerEnter script instead?
