46 secured thereto will move with label 14 away from switch 62 it should also be noted that spacers 32 provide anvils or pressure plates against which switches 62 abut with switches 62 being sandwiched between spacers 32 and 46 when actuated thus spacers 32 prevent front 16 and voice modules 60 secured thereto from simply deflecting inwardly when a particular switch 62 was desired to be actuated according to the teachings of the present invention label 14 stretched over speaker openings 38 vibrates with speakers 64 of voice modules 60 and thus itself acts as a speaker specifically speakers 64 are held relatively close to and parallel to label 14 and due to the restricted air passage from between front 16 and voice modules 60 provided by strips 66 the vibration of speakers 64 will move the air between speakers 64 and label 14 causing label 14 covering openings 38 to vibrate thus label 14 acts as a speaker especially for high frequency sounds vent holes 68 allow the lower frequency sounds caused by the air moving between speakers 64 and back panels 20 and 22 to pass therethrough it should be noted that high frequency sounds have difficulty in passing out vent holes 68 but generally come from the front by label 14 and speakers 64 thus board 10 according to the preferred teachings of the present invention is particularly.
