发明名称 Wireless communication apparatus with a flat speaker
摘要 A wireless communication apparatus integrates a flat speaker (33) onto a liquid crystal display (12) or a rotational shield (3) of the apparatus. The flat speaker includes a vibrator (30) and a transparent vibrating membrane (31) which generates sound when the vibrator vibrates. The transparent vibrating membrane is mounted with a predetermined spacing over the liquid crystal display or over an inner surface of the rotational shield so as to gain a broader voicing surface. Thereby, by providing the flat speaker, the wireless communication apparatus can have a better audio effect.
