PURPOSE:To generate sounds of high quality with a small-sized constitution by using a hand storing space also as an acoustic region of a speaker. CONSTITUTION:An air hole 10 is formed between the hand storing space 30 and an acoustic space 29 on the back of the speaker 6 and both the spaces are connected to form an acoustic space. Therefore, the space 30 is also used as an acoustic space, so that an electronic watch generating sounds of high quality can be obtained with a small-sized constitution. |
