  FIG. 4 is a flowchart showing a procedure of operation control of the sample listening speaker device 10 performed by the microcomputer CP.

  Next, the operation of the audition speaker device 10 will be described based on the flowchart of FIG.

  When the power source PS is turned on, the trial listening speaker device 10 is supplied with power from the power source PS to the player PL, and an audio signal is output from the player PL. Further, the human body detection sensors SE1, SE2, SE3, SE4. In this state, the human body detection sensors SE1, SE2, SE3, and SE4 can detect the human body.

  In this state, the microcomputer CP determines whether or not a human body detection signal is input from the human body detection sensors SE1, SE2, SE3, and SE4 attached to the front panels of the speaker boxes B1, B2, B3, and B4. Detection is always performed (step S1).

  When the input of the human body detection signal is detected in step S1, it is next determined whether or not the human body detection signal is input from two or more human body detection sensors (step S2).

  Next, when it is determined in step S2 that human body detection signals are input from two or more human body detection sensors, the microcomputer CP is the largest of the plurality of human body detection signals that are input. The human body detection sensor that outputs the human detection signal of the value is determined (step S3).

  The determination in step S2 is that the human body detection sensors SE1, SE2, SE3, and SE4 are such that the detection ranges (angle ranges) in the forward direction of the respective speaker boxes B1, B2, B3, and B4 are the smallest in overlapping portions. However, if the speaker boxes B1, B2, B3, and B4 are arranged close to each other, it is inevitable that the detection ranges overlap. • To determine if you are closest to the box.

  The microcomputer CP determines a human body detection sensor that outputs a human body detection signal (a human body detection sensor that outputs a human body detection signal having the largest value when a plurality of human body detection signals are input). Then, when the speaker that performs sound output is determined among the speakers SP1, SP2, SP3, and SP4, the sound output is determined by outputting the change signal to the first changeover switch SW1 and switching the first changeover switch SW1. The performed speaker and player PL are connected (step S4).

  Further, the microcomputer CP outputs a switching signal to the second changeover switch SW2 and switches the second changeover switch SW2, thereby illuminating the speaker box to which the speaker that has decided to perform sound output is attached. Is connected to the power source PS, and the display of the speaker box is turned on (step S5).

  By turning on the display, the listener can recognize the speaker that is outputting sound among the speakers SP1, SP2, SP3, and SP4.

  Further, the listener recognizes the type and model of the speaker that is outputting the sound and the sound quality, etc., by visually recognizing the display on the display section Da1 or Da2, Da3, Da4 of the lit display. You will be able to

  In addition, the listener can determine which direction to move next for the purpose of listening comparison by displaying the arrow of the direction indicator Db1 or Db2, Db3, Db4 of the lit display. .

  The microcomputer CP outputs an announcement signal and an operation control signal for announcing speaker switching to the audio announcement mixer M almost simultaneously with the steps S4 and S5, and outputs the announcement signal and the player PL. The audio signal is mixed with the received audio signal (step S6).

  With the announcement signal mixed with the audio signal, the announcement that informs the listener that the speaker has been switched is performed from the speaker that outputs the sound.

  The microcomputer CP outputs a volume control signal to the volume controller VC almost simultaneously with the steps S4, S5 and S6, so that the volume controller VC adjusts the volume of the audio signal (step S7). .

  The volume control setting by the volume controller VC is performed when comparing the output efficiency with the same input level of the speakers SP1, SP2, SP3 and SP4, or when comparing the sound quality with the same sound pressure level. Etc., as appropriate, based on the request of the listener or store.

  As described above, the listener can simply listen in front of any one of the speaker boxes B1, B2, B3, and B4, and the sound is output from the speaker, and the sound output from the speaker can be auditioned. I can do it.

  While the sampler is listening to the speaker, the microcomputer CP outputs a switching control signal to the second changeover switch SW2 in accordance with a preset program so that the sampler can audition next. It is also possible to cause the display of the recommended speaker box to blink by connecting / disconnecting the switch for connecting the illumination of the recommended speaker box and the power source PS at equal intervals.

  As described above, while the procedure up to step S9 is performed, the microcomputer CP continues to detect whether or not the human body detection signals are input from the human body detection sensors SE1, SE2, SE3, and SE4 in step S1. Is going.

  If the input of the human body detection signal is not detected in step S1, it is next determined whether or not the input of the human body detection signal was detected immediately before (step S8).

  In step S8, if the input of the human body detection signal was detected immediately before, the microcomputer CP outputs a switching signal to the first switching switch SW1 and the second switching switch SW2, and the first switching is performed. By disconnecting the switch SW1 and the second changeover switch SW2, the connection between the speaker and the player PL and the display illumination and the power source PS is cut off (step S9).

  As described above, when the listener moves outside the detection range of each human body detection sensor SE, SE2, SE3, SE4 of the speaker device for trial listening 10, and no human body detection signal is input to the microcomputer CP, The sound output from the speakers SP1 or SP2, SP3, SP4 is stopped.

  If the listener has moved to the detection range of another human body detection sensor, the human body detection sensor that is newly outputting the human body detection signal is determined in steps S2 and S3, and the first changeover switch SW1 is selected. When the second switch SW2 is switched, a new sound is output from the speaker located almost in front of the listener by the procedure of steps S4 to S7 as described above.

  On the other hand, if the human body detection signal has not been detected immediately before in step S8, and after the sound output from all the speakers SP1, SP2, SP3, SP4 is blocked in step S9, the microcomputer CP is Then, a switching signal is output to the second changeover switch SW2, and each contact point of the second changeover switch SW2 is connected / disconnected at a predetermined interval (for example, 0.5 second interval), and each speaker box B1 is connected. , B2, B3, and B4 displays D1, D2, D3, and D4 are blinked in any order (step S10).

  As a result, the appeal of the product and sales promotion can be promoted by appealing the presence of the trial listening speaker device 10 to the store visitor and suggesting the order of the trial listening speakers.
