Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention mainly relates to a television receiver having a timer function for automatically turning off the power when a time set by the viewer elapses, mainly for the purpose of preventing the power from being turned off at bedtime. is there.

[0002]

[Prior art]

 In recent years, when a time is set for a television receiver by manual operation of an operation input unit such as a remote control transmitter, the power is automatically turned off at the time when the set time has elapsed from the set time. Many have a timer function. This timer function is used to set the time to go to bed or the time according to the end time of a desired broadcast program in the television receiver, and automatically turn off the power when the broadcast program ends. This is used to save the trouble of turning off the power at the end of the broadcast program, and to prevent the problem of forgetting to turn off the power and going to sleep.

[0003]

[Problems to be solved by the invention]

 By the way, those who use the timer function before going to bed want to watch a desired broadcast program before going to bed and turn off the power when the broadcast program ends, and also want to fall asleep immediately. Is common. However, even after the power of the television receiver is turned off by the timer function, the patient may not be able to fall asleep quickly due to high spirits or a change in the environment. In particular, inpatients who must lie all day in a hospital bed often fall asleep even in the daytime, so they cannot sleep at night. In such a state, the timer function cannot achieve its intended purpose.

[0004] Apart from the above, conventionally, a sleep device that emits a sound in synchronization with a human breathing cycle to calm the mind and effectively induce sleep (Japanese Patent Laid-Open No. 2001-224690). Japanese Unexamined Patent Application Publication No. Hei 11 (1999)), reproducing a user's own heart sound recorded in advance, or generating a pseudo heart sound adjusted to the heart sound to improve sleep. -290457) has been proposed. However, if the television receiver is turned off at the set time and it is desired to fall asleep immediately, the above-described device or equipment for promoting sleep is placed separately from the television receiver at the bedside. This is not only costly and uneconomical, but also requires that the same time be accurately set in both the timer function of the television receiver and the device that promotes sleep, which makes the setting of the time troublesome. In addition, if there is a difference between the set times, a problem occurs in which a sound is emitted from the sleep device while watching the broadcast program on the television receiver.

In view of the above, the present invention has been made in view of the above-described conventional problems, and has an effective function corresponding to the operation of the timer function in addition to a timer function for turning off the power at a set sleep time. It is an object of the present invention to provide a television receiver which also has a relaxation function of inviting a person to sleep and promoting a good night's sleep.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, a television receiver according to the invention according to claim 1 includes a broadcast receiving unit that detects a received television broadcast wave after converting the frequency, and an audio signal from the broadcast receiving unit.

A rhythm sound signal generation circuit, an operation input unit having a function of setting and inputting a sleep time to be turned off, a timer circuit for measuring time, and a time when the sleep time is input from the operation input unit The rhythm sound signal generation circuit is activated for a predetermined time from the time when the timer circuit times out or a predetermined time before the time up. In together when the output from the speaker rhythm sound signals by driving the timer circuit is characterized by comprising a control section that controls so as to turn off the power when the time is up.

In this television receiver, in addition to a timer function in which power supply is automatically cut off at a sleep time, in accordance with the cutoff of the power supply, 60 or more times per minute close to a human heart rate are provided. Rhythm sound synchronized with multiple times of this is output, and it also has a relaxation function that gradually invites sleepiness while making the viewer feel relaxed and comfortable, especially in hospitals where it is difficult to sleep. It can be used very effectively for inpatients and the like. In addition, since the relaxation function can be configured by using components such as existing speakers in the television receiver, the cost is not much higher than that of the existing television receiver, and the television receiver itself is not required. Since it also has a relaxation function, it is extremely easy to use as compared with the case where another sleeping device, etc., is separately provided for a television receiver.

[0008] A television receiver according to a second aspect of the present invention includes a speaker for outputting an audio signal of a received television broadcast wave, and a rhythm sound signal being output at a timing of 60 times per minute or a multiple thereof. A rhythm sound signal generating circuit to be output, and a power supply being turned off at a time when a sleep time set and input by manual operation is reached, and the rhythm being output at a predetermined time before the sleep time or from the time when the sleep time is reached. A control unit that drives the sound signal generation circuit for a predetermined time to output the rhythm sound signal from the speaker.

According to this television receiver, in addition to the timer function of automatically shutting off the power supply at the time of sleep, the rhythm sound is output to gradually relax the viewer while making the viewer feel relaxed and comfortable. It also has a relaxation function to invite you to a destination. Moreover, since the relaxation function can be configured by using components such as existing speakers in the television receiver, the cost is not so high as compared with the existing television receiver, and the television receiver itself is not required. Since it also has a relaxation function, it is extremely easy to use as compared with a case where a separate sleeping device, etc., is separately provided for a television receiver.

A television receiver according to a third aspect of the present invention further includes a timer circuit in addition to the configuration according to the second aspect of the present invention, wherein the rhythm sound signal generation circuit operates in an inaudible frequency range.

It has a configuration to control.

[0013] According to this configuration, even when all program broadcasts of the channel being received have ended before the sleep time, the viewer performs an operation of turning off the power of the television receiver. It is not necessary, and listening to the rhythm sounds calms the mind and effectively invites you to sleep. In addition, in a state where the viewer is invited to a comfortable drowsiness by the inaudible rhythm sound, by listening to the audible rhythm sound for a predetermined time from the sleep time, the emotional stabilization is further promoted. Eventually, it will almost certainly fall asleep.

[0014]

[Embodiment of the invention]

 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a functional block diagram of a main part of a television receiver according to an embodiment of the present invention. In the figure, in order to facilitate understanding, a well-known configuration inevitably provided for practical use is omitted, and the configuration is illustrated as a simplified configuration.

The television receiver includes a reception antenna 1 for a television broadcast wave, a broadcast reception unit 2 including a well-known tuner, an IF (intermediate frequency) amplification unit, a detection unit, and the like, a well-known video amplification unit, A video processing unit 3 having a color demodulation unit and a video output unit; a display 4 such as a CRT or LCD for displaying a video signal on a screen; and a well-known audio demodulation unit, a voice amplification unit and a voice output unit. A processing unit 7, a speaker 8 for outputting an audio signal of a television broadcast wave, a CPU for controlling each unit, and a ROM and a RAM in which a control program and control data to be executed by the CPU are stored, respectively. A control unit 9 composed of a microcomputer for controlling each unit of the television receiver main body, and various operation signals to the control unit 9 are manually operated. An operation input unit 10 such as a remote control transmitter for inputting a signal, and a power supply circuit unit 11 for supplying drive power to components of each unit are provided. The above configuration is almost the same as the existing configuration provided in the conventional television receiver.

The television receiver is provided with a rhythm sound signal generation circuit 12 that generates and outputs a rhythm sound signal capable of outputting a rhythm sound in which a single electronic sound is emitted at a constant cycle from the speaker 8. It is characterized by having. The rhythm sound signal generation circuit 12 has an inaudible frequency range rhythm sound generation unit 12a and an audible frequency range rhythm sound generation unit 12b. The inaudible frequency range rhythm sound generation unit 12a synchronizes with a repetition timing of 60 times or a multiple thereof, 120 times per minute, which is close to the human heart rate, and adjusts the low sound pressure in the inaudible frequency range (high frequency range). It generates and outputs an inaudible frequency range rhythm sound signal for outputting the inaudible rhythm sound. The audible frequency range rhythm sound generation unit 12a also synchronizes with the repetition timing of 60 times or a multiple of 120 times a minute close to the heart rate of a human to produce a low sound pressure in the audible frequency range (low frequency range). Generate and output an audible frequency range rhythm sound signal for outputting the audible rhythm sound.

The inaudible frequency range rhythm sound generation unit 1a and the audible frequency range rhythm sound generation unit 12b are selectively driven by a command from the control unit 9 to generate the audible frequency range rhythm sound signal or audible signal. Outputs a frequency rhythm sound signal. The output inaudible frequency range rhythm sound signal or audible frequency range rhythm sound signal is amplified by the audio signal amplifying circuit 14 and then superimposed on the audio signal of the television wave by the audio signal superimposing section 17. Alternatively, when there is no audio signal, the audio signal is directly supplied to the speaker 8 and output as an inaudible rhythm sound or an audible rhythm sound.

When a time setting signal is input by a manual operation of the operation input unit 10, the control unit 9 activates the timer circuit 18 and, based on the time signal received from the timer circuit 18, activates the timer circuit 18. The elapse of the set time from the operation input unit 10 is monitored, and when it is determined that the time that is a predetermined time before the set time has elapsed, the inaudible frequency range rhythm sound generation unit 1a is instructed to drive. When it is determined that the set time has elapsed, a drive command is issued to the audible frequency range rhythm sound generation unit 1b.

Further, the main body of the television receiver is provided with an audio signal presence / absence detection circuit 19 for detecting whether or not an audio signal is being output from the audio processing unit 7. The audio signal presence / absence detection circuit 19 detects when the audio signal is no longer output from the audio processing unit 7 after all broadcast programs on the currently received channel have ended and sends a detection signal to the control unit 9. Is output. Upon receiving this detection signal, the control unit 9 instructs the power supply circuit unit 11 to immediately cut off the power supply to the main circuit unit even during the above-described time counting operation of the set time.

Next, control processing by the control unit 9 will be described with reference to the flowchart of FIG. The control section 9 constantly monitors whether or not a time setting signal of a sleep time is input from the operation input section 10 (step S1). If a viewer of a broadcast program of a television receiver wishes to go to bed after watching a broadcast program scheduled to end at 10:45 pm at, for example, 9:20 pm, the television In many cases, the sleep time is generally set in units of 30 minutes in the receiver, so that the user manually operates the operation input unit 10 to set and input the time of 1 hour and 30 minutes. Therefore, in this case, 10:50 pm is set and input as the sleep time.

When it is determined that the sleep time has been set and input (step S 1), the control unit 9 instructs the timer circuit 18 to start, and based on the time data fetched from the timer circuit 18, sets the sleep time. Monitoring is started (step S2). Subsequently, the control unit 9 determines whether or not the detection signal has been input from the audio signal presence / absence detection circuit 19, that is, whether or not all the program broadcasts of the receiving channel have ended and the audio signal has disappeared (step S3). ) And a determination as to whether or not a predetermined time before the sleep time has been reached (step S4). The above-mentioned fixed time can be arbitrarily changed and set, but in this embodiment, it is assumed that it is set to 15 minutes. Therefore, in this case, the control unit 9 determines whether or not it is 10:35 pm, 15 minutes before 10:50 pm of the sleep time.

When the control unit 9 determines that all broadcast programs of the channel being received have reached a time a predetermined time before the sleep time without ending, that is, 10:35 pm (step S 4) Then, it instructs the rhythm sound signal generation circuit 12 to drive the inaudible frequency range rhythm sound generation unit 12a. As a result, the inaudible frequency rhythm sound signal output from the inaudible frequency range rhythm sound generation unit 12a is amplified by the audio signal amplification circuit 14, and then the audio signal superposition unit 17 outputs the television signal from the audio processing unit 7 The signal is superimposed on the radio wave audio signal and output from the speaker 8 as an inaudible rhythm sound (step S5).

At 10:35 pm, the program being watched by the viewer is being broadcast, but the inaudible rhythm sound that is output by being superimposed on the audio signal of the broadcast program is output from the speaker 8. The low sound pressure in the inaudible frequency range does not impair the sound of the broadcast program, and the viewer can watch the broadcast program without any trouble. However, the inaudible rhythm sound is output in synchronization with a repetition timing of 60 times or a multiple thereof per minute which is close to the human heart rate. Immediately before sleep, it has the effect of making you feel relaxed and comfortable and inviting you to sleep. In this way, even if the viewer is drowsy, it is 10 minutes before the broadcast program being watched, so it is not so inconvenient for the viewer.

Subsequently, the control unit 9 determines whether or not there is an audio signal based on the presence or absence of the detection signal from the audio signal presence / absence detection circuit 19 (step S 6), and determines whether or not the sleep time has been reached. The determination (step S7) is repeated. In this case, the broadcast program viewed by the viewer ends at 10:45 pm, which is 10 minutes after 10:35 pm when the above-mentioned inaudible rhythm sound was output, and the afternoon after 5 minutes, 10:50 is the sleep time set by the viewer. Therefore, the inaudible rhythm sound is output 10 minutes before the end of the broadcast program being watched by the viewer and is continuously output until 5 minutes have elapsed since the end of the program. During this time, the viewer will be gradually invited to sleepiness by the inaudible rhythm sound while watching the broadcast program.

At 10:50 pm, when the control unit 9 determines that the sleep time has been reached without ending all the program broadcasts of the channel being received (step S 7), the control unit 9 generates a rhythm sound signal. After instructing the circuit 12 to stop driving the inaudible frequency range rhythm sound generation unit 12a (step S8), the power supply unit 11 supplies power to the rhythm sound signal generation circuit 12 and the speaker 8 A command is issued to cut off the power supply to the main circuit except for the supply (step S9). As a result, in the main body of the television receiver, the screen display on the display 4 and the sound output from the speaker 8 are both stopped, as in the case of the conventional timer function. At the same time, the control unit 9 instructs the rhythm sound generation unit 12 to drive the audio frequency range rhythm sound generation unit 12b, and outputs the audio frequency range rhythm sound output from the audio frequency range rhythm sound generation unit 12b. The signal is output from the speaker 8 as an audible rhythm sound (step S10).

The output of the audible rhythm sound determines that a predetermined time (for example, 10 minutes) that has been set in advance from the sleep time has elapsed from the sleep time based on the timing data taken from the timer circuit 18 by the control unit 9 (step S11). Continue until you do. At this time, the output of the audio signal of the television broadcast wave is cut off, so that there is no problem even if the audible rhythm sound is output from the speaker 8. In the state where the above-mentioned inaudible rhythm sound induces a soothing drowsiness, the audience can further stabilize the emotion by listening to the audible rhythm sound, and eventually, the sleep can be almost certainly achieved. State.

When the control unit 9 determines that the predetermined time has elapsed (step S11), the control unit 9 resets the timer circuit 18 (step S12), and then sends the live sound generation circuit 12 and the A command is issued to cut off the power supply to the speakers 8 (step S13), and a series of control processing ends.

Note that, depending on the sleep time set and input by the viewer, all program broadcasts of the receiving channel may end before the sleep time. In such a case, the control unit 9 determines that an audio signal is not output with the end of the program when the detection signal is input from the audio signal presence / absence detection circuit 19 (steps S3 and S6), and the timer circuit After resetting (step S14), the power supply circuit unit 11 is instructed to cut off the power supply to the main circuit unit (step S9). A command is issued to drive the rhythm sound generation unit 12b, and an audible rhythm sound is output from the speaker 8 (step S10). After outputting the audible rhythm sound for a predetermined time, the timer circuit 18 is reset. (Step S12), and instructs the power supply circuit section 11 to cut off the power supply to the rhythm sound signal generation circuit 12 and the speaker 8 (Step S13).Also in this case, the viewer does not need to perform an operation of turning off the power of the television receiver, and is calmed down by listening to the audible rhythm sound, and is effectively induced to sleep.

This television receiver is provided with a simple configuration in which a rhythm sound signal generation circuit 12 is mainly provided, and has a timer function such as an existing timer circuit 18 and a speaker 8 of a main body of the television receiver. The inexpensive configuration that uses existing components also has a relaxation function that prompts the viewer to be effectively drowsy when the power supply is cut off by the timer function. Therefore, this television set can be used very effectively especially for inpatients in hospitals where it is difficult to sleep.

The present invention is not limited to the above embodiment. For example, the clocking of the sleep time may use the clock function of the microcomputer as the control unit 9. The timing of outputting the inaudible rhythm sound can be set arbitrarily.

[0031]

[Effect of the invention]

 As described above, according to the television receiver of the present invention, in addition to the timer function in which the power supply is automatically cut off at the sleep time, in accordance with the cutoff of the power supply, the power supply is close to the human heart rate. The rhythm sound synchronized with the timing 60 times or multiple times per minute is output, and it has a relaxation function that gradually induces sleepiness while making the viewer feel relaxed and comfortable. In particular, it can be used very effectively for inpatients in hospitals where it is difficult to sleep. In addition, since the relaxation function can be configured by using components such as existing speakers in the television receiver, the cost is not much higher than that of the existing television receiver, and the television receiver itself is not expensive. Since it also has a relaxation function, it is extremely easy to use as compared with the case where another sleeping device such as a television receiver is separately provided.
