A portable electronic apparatus (100, 1000) includes a housing wall (116, 516, 916, 1012), and a piezoelectric transducer (118) unitized with the housing wall (116, 516, 916, 1012). The housing wall (116, 516, 1012) can be overmolded with the piezoelectric transducer (118) or the piezoelectric transducer (118) can be bonded to the wall (916). The portable electronic apparatus can for example comprise a watch (100) or a wireless communication device (1000). The piezoelectric transducer (118) can be driven to vibrate so as to produce a perceptible tactile or audible alert. The geometry of the piezoelectric transducer (118) and the manner in which it is integrated with the electronic apparatus (100, 1000) are such that only a small volume is required to accommodate the piezoelectric transducer (118).
