PURPOSE:To enable to obtain superior voice edge in a composite type speaker by making it possible to change the direction of a high frequency speaker independently of the direction of a low frequency speaker. CONSTITUTION:In case of low frequency speaker 1, the periphery of frame 2 is fixed on the speaker fitting panel 3. Concave part 6 whose bottom surface forms a circular arc is formed on the center portion of frame part 4 formed in a body with speaker fitting panel 3 so as to divide sound discharging hole 5 formed on speaker fitting panel 3 into two sections, and guide grooves 7 and 7 are provided on the both sides of concave part 6. High frequency speaker 9 is fixed on speaker fitting body 8 and speaker fitting body 8 can move along guide grooves 7 and 7 to the direction of A and A'. Thus, by remaining the direction of the low frequency speaker fixed, the direction of the high frequency speker can be changed, so that the high frequency speaker with high directivity can be exclusively directed to the listener, making it possible to obtain superior voice edge. |
