DESCRIPTION JPH02256399
[0001]
TECHNICAL FIELD The present invention relates to a speaker device that constitutes an audio
system. In recent years, with the spread and appearance of devices capable of providing highquality sound source sources such as compact disc players and digital audio tape recorders, the
speaker apparatus in the audio system has a strong tendency to seek better sound quality ( With
the high operability of sound sources such as compact discs, music can be more easily enjoyed
close to them, and a speaker device that can be used in a wide range of applications and can
handle various types of music is indispensable. The conventional speaker devices are one-way
speaker devices (devices equipped with one speaker), two-way speaker devices (devices equipped
with two speakers such as low frequency and high frequency) for both home use and car use.
There are a wide variety of speaker devices such as a 3-way speaker device (a device provided
with three speakers such as low frequency, middle high frequency, and high frequency). The 1way speaker device is a speaker device that reproduces a music signal with one speaker, and the
speaker device with two or more windows includes a plurality of speakers, and one or more
networks of music signals to each speaker It is a speaker apparatus which makes each speaker
share a reproduction frequency using a circuit (an electric circuit for limiting the frequency band
of a music signal). SUMMARY OF THE INVENTION However, in the above-described speaker
apparatus, all the speakers constituting the speaker apparatus and a network circuit specific to
each speaker are stored in one speaker box (hereinafter, referred to as an enclosure). It has been
difficult to change or construct a speaker device, such as changing or increasing or decreasing a
speaker suitable for a listener or suitable for a music source. An object of the present invention is
to provide a speaker apparatus capable of freely and easily combining and changing a speaker
and a network circuit in order to solve the above-mentioned conventional problems. Means for
Solving the Problems In order to solve the problems, the speaker device according to the present
invention comprises a plurality of circuit units for limiting the frequency band of an input signal,

1
a sensor portion for detecting a connection state of a speaker unit, and the sensor According to a
signal from a part, an output signal from the circuit unit is selected, and a switch unit for guiding
the signal to the speaker is added. Operation With this configuration, the listener can easily
change the speakers and the network circuit to a speaker device suited to the listener's
preference and music source by combining a plurality of speaker devices constituting the
speaker device.
Embodiment An embodiment of the present invention will be described with reference to the
drawings. FIGS. 1a to 1d show a top view, a front view, a bottom view, and a rear view of one
speaker device constituting the speaker device according to an embodiment of the present
invention. In FIG. 1, 1 is an enclosure, 2 is a speaker, and 3 and 4 are joint portions for
connecting the speaker units 5 consisting of an enclosure 1 incorporating a plurality of speakers
2 (3 is convex, 4 is concave, both are Form part of the connection). The connecting part 3 ░ 4
forms a part of the sensor of the speaker unit 5 and a part of the switch part, and the network
circuit in the speaker unit 5 is switched by the switch according to the presence or absence of
connection of the connecting parts 3 and 4 Select the audio signal to be output. 2 and 3 are
external views when used with only one speaker unit 5 and when connected and used with
speaker units 5a and 5b of two different specifications, and 6 shows a speaker stand There is.
FIG. 4 is a block diagram when the speaker apparatus is configured by the two speaker units 5a
and 5b shown in FIG. 7, 8.9 is a part of the sensor, 10. 11 is a network circuit portion, 12. 13 is a
switch portion, 2a. ??????????? The operation of the loudspeaker apparatus
configured as described above will be described below. As shown in FIG. 3, the speaker unit 5a.
When 5b is used alone, it operates as a 1-way full-range speaker device (without limitation of the
frequency band of the input signal to the speaker), and when the speaker units 5a and 5b are
connected, the network circuit inside the speaker units 5a and 5b 10.11 works and both speaker
units 5a and 5b receive restriction of the frequency band of the input signal to the speakers 2a
and 2b, and the speaker 2a works as a low band reproduction (woofer speaker) and 2b as a
middle high band reproduction (. The above operation will be described with reference to FIG.
The connection state of the speaker units 5a and 5b is determined by the sensor portions 7 to 9
combined with the coupling portions 3 and 4 for connecting the speaker units 5a and 5b, and the
determination result is transmitted to the switch 12.13 for switching the network. It is possible to
switch to a network circuit that is optimal for the state of the entire speaker device. As described
above, according to the present embodiment, a switch for switching the network of the circuit
unit, a circuit unit for limiting the frequency of the input signal in the speaker unit, a part of the
sensor for detecting the connection state of the plurality of speaker units, By providing a unit and
changing the combination of the plurality of speaker units, the listener can easily construct a
speaker device which is tailored to his taste or suitable for a music source.
As described above, according to the present invention, the speaker unit is configured by

2
providing the network circuit, the network switching switch, and a part of the sensor that detects
the connection state of the speaker unit in the speaker unit (speaker unit, network Circuits can be
easily changed or increased / decreased to realize an excellent speaker device.
