Abstract

PURPOSE:To obtain the optimum frequency characteristics which are well balanced in terms of the hearing sense in both sealed-up and bass reflex systems, by switching a high band characteristics changeover switch in response to a bass reflex/sealed-up system switching device. CONSTITUTION:A tweeter 2, a woofer 3 and a buss reflex/sealed-up system switching device 5 are attached to a baffle plate of a cabinet 1. The device 5 closes the opening of a buss reflex port to switch the buss reflex system to a sealed-up system and opens the opening the bass reflex port to switch the sealed- up system to the bass reflex system. A high band characteristics changeover switch 6 interlocks the function of the device 5, and the output level of the tweeter 2 of a branch circuit 4 is switched by the position of the switch 6 as shown in the figure. As shown in the figure, the output of the tweeter 2 of the circuit 4 is attenuated at a position (a) of the switch 6 and not attenuated at a position (b) respectively.

得ることが困難であった。(Problems with the Prior Art) FIG. 1 shows a conventional speaker/stem, in which 1 is a cabinet, 2 is a treble speaker, and 3 is a bass speaker. In general, the low frequency characteristics of a closed speaker system are second to none.
The solid line 7 in the figure shows the characteristics as shown in the broken line 8 in the same figure for the thin-reflex type.In the sealed type and the thin-reflex type, not only the difference in frequency characteristics, but also the difference in Q at the resonant frequency influences the sound preference. Therefore, there are conventional examples that make it possible to switch between the two. However, in the conventional example, the high frequency characteristics do not change, so it is difficult for general users to obtain an optimal frequency balance, for example, when using a bass reflex, too much bass is produced.

Switch to the bass reflex system by opening the bass reflex port opening. A switch 6 for switching high frequency characteristics is provided which is linked to the movement of the bass reflex/sealed switching device 5, and depending on the position of this switch 6, the level of the high frequency spill force output of the branching circuit 4 can be changed as shown in FIG. It will be done. In FIG. 5, the high frequency output of the branching circuit 4 is attenuated at position a of the high frequency characteristic changeover switch 6, and is not attenuated at position a. If the switch 6 is set to position aK when the switching device 5 is closed to set the sealed system, and the switch 6 is set to position b when the switching device 5 is opened to set the bass reflex system, the frequency characteristics of the speaker/stem will be In FIG. 4, the closed type has a characteristic 7 shown by a solid line, and the bass reflex type has a characteristic 8 shown by a broken line.
