Description

  The present invention relates to a battery-less peripheral device that operates by being supplied with power from a main device when an electronic device having a four-pole phone jack such as a smartphone is used as the main device.

  There are various known so-called batteryless peripheral devices that operate by receiving power supply from the smartphone side by connecting the 4-pole phone plug provided by the smartphone to the 4-pole phone jack on the smartphone side (for example, Patent Document 1). 2).

  The 4-pole phone jack on the smartphone side has a first jack electrode for outputting a sound signal to the right earphone speaker and a second jack electrode for outputting a sound signal to the left earphone speaker. And a bias voltage supplied to a capacitor microphone (more precisely, a two-wire electret capacitor microphone unit: ECM unit with a built-in FET for impedance conversion) and a sound signal input from the capacitor microphone. There is a third jack electrode and a fourth jack electrode for providing a ground potential.

  On the other hand, on the battery-less peripheral device side, the first plug electrode, the second jack electrode, the third jack electrode, and the fourth jack electrode respectively correspond to the first jack electrode, the second jack electrode, There are two plug electrodes, a third plug electrode, and a fourth plug electrode.

  Therefore, between the smartphone and the battery-less peripheral device, there are two downstream sound signal lines (the first sound signal line via the first jack electrode and the first plug electrode, and the second jack electrode). There is a second sound signal line that passes through the second plug electrode) and one upstream sound signal line (a third sound signal line that passes through the third jack electrode and the third plug electrode).

  Conventionally, power supply from the smartphone to the batteryless peripheral device is performed via any one of the two downstream sound signal lines described above. Specifically, a sound signal consisting of a sine wave having a constant frequency and amplitude is sent from the corresponding analog output port on the smartphone built-in processor side to either one of the first or second jack electrode. Is done. According to the sound signal of such a signal form, on the side of the battery-less peripheral device, a simple passive circuit such as a rectifier circuit and a smoothing circuit is prepared. This is because power can be generated.

JP 2014-036332 A Japanese Patent No. 5552191

  As described above, when power is supplied from the smartphone to the battery-less peripheral device, one of the two downstream sound signal lines is occupied for power supply. This means that although there are two downstream sound signal lines between the smartphone and the batteryless peripheral device, one of them will be occupied for power supply, so the smartphone will be batteryless. This means that only one sound signal line is left in order to send some signal (for example, analog sound signal or digital data signal) to the peripheral device side.

  For this reason, in a battery-less peripheral device, for example, if an additional function (for example, flashing of light according to the strength of sound) is to be realized while sound can be reproduced with an earphone speaker, a downstream sound signal line Since only one can be used, the sound of the left or right channel cannot be reproduced from the earphone speaker, and stereo sound reproduction must be abandoned.

  In addition, in a battery-less peripheral device, for example, while receiving a series of digital data transmitted from a smartphone, some additional function (for example, a function of writing such data into a memory or a function of writing into a card) is to be realized. Then, for data transmission in this type of peripheral device, a modulation method (for example, amplitude modulation method (ASK), frequency modulation method (FSK)) using a carrier wave of a relatively low frequency (audible frequency or about that) is generally used. Since a phase modulation method (PSK) or the like is employed, a necessary transmission speed may not be sufficiently ensured with only one downstream sound signal line.

  The present invention has been made in view of the above-described technical background, and the object of the present invention is to receive two power signal lines while receiving power necessary for operation from a main device represented by a smartphone. With a 4-pole phone jack, both of these can be freely used for applications other than power transmission, and at the same time, a single sound signal line can be used to realize more advanced peripheral functions. It is to provide a battery-less peripheral device.

The battery-less peripheral device according to the present invention is a device that operates by being supplied with power from the main device when an electronic device having a 4-pole phone jack such as a smartphone or a home game machine is used as a main device.

<I / O circuit on main unit>
As a main device to which the batteryless peripheral device of the present invention is applied, various devices having a four-pole phone jack such as a smartphone and various home game machines can be considered. In the following, an example of the input / output circuit will be outlined by taking a smartphone as an example of these devices as an example.

  A schematic configuration diagram of a sound input / output circuit of a smartphone is shown in FIG. As is well known to those skilled in the art, this type of 4-pole phone jack J includes a CTIA standard (see (a) in the figure) and an OMPT standard (see (b) in the same figure). Are known. The CTIA standard 4-pole phone jack J is often used in, for example, android (registered trademark) smartphones, while the OMPT standard 4-pole phone jack J is often used in ios (registered trademark) smartphones. . All standard 4-pole phone jacks have basically the same hardware configuration, and have four jack electrodes J1, J2, J3, and J4 from the back of the insertion slot toward the entrance.

  The first and second jack electrodes J1 and J2 have a built-in smartphone as shown in FIGS. 4A and 4B, regardless of the standard 4-pole phone jack. Two sound signals output from two analog output ports not supplied are supplied through amplifiers A1 and A2, respectively.

  Here, the contents of the two sound signals are different between the case of the tone reproduction mode and the case of the data transmission mode. That is, in the music sound reproduction mode, the contents of the two sound signals are the audio signals themselves of the left and right channels, whereas in the data transmission mode, a carrier (for example, an audio frequency) is transmitted depending on the transmission data. Alternatively, a sine having a frequency in the vicinity thereof is a modulated data signal obtained by modulating an AC signal or the like by a predetermined modulation method (for example, a frequency modulation method, a phase modulation method, an amplitude modulation method, or the like).

  The contents of signals supplied to the third and fourth jack electrodes J3 and J4 are different between the case of the CTIA standard and the case of the OMPT standard.

  That is, in the case of the CTIA standard, as shown in FIG. 6A, the GND potential is supplied to the third jack electrode J3, while the fourth jack electrode J4 is connected to a capacitor microphone (exactly not shown). Is commonly used for supplying a bias voltage to a two-wire electret condenser microphone unit (ECM unit) incorporating an FET for impedance conversion and for inputting a sound signal from the condenser microphone.

  More specifically, as shown in FIG. 5A, the power supply voltage VCC passes through the resistor R01 and is then supplied to the fourth jack electrode J4 as a bias voltage of a capacitor microphone (not shown). At the same time, a sound signal from a capacitor microphone (not shown) is taken in from the fourth jack electrode J4, then passes through a coupling capacitor C01 and an amplifier A3, and then an analog input port (A / D conversion) (not shown) of the processor built in the smartphone. ). On the other hand, the third jack electrode J3 is connected to GND.

  On the other hand, in the case of the OMPT standard, as shown in FIG. 5B, the GND potential is supplied to the fourth jack electrode J4, while the third jack electrode J4 is a capacitor microphone (not shown). (Accurately, it is commonly used for supplying a bias voltage to a two-wire electret condenser microphone unit: ECM unit incorporating an FET for impedance conversion) and for inputting a sound signal from the condenser microphone.

  More specifically, as shown in FIG. 5B, the power supply voltage VCC passes through the resistor R01 and is then supplied to the fourth jack electrode J3 as a bias voltage of a capacitor microphone (not shown). At the same time, a sound signal from a capacitor microphone (not shown) is taken in from the third jack electrode J3, then passes through the coupling capacitor C01 and the amplifier A3, and then an analog input port (A / D conversion) (not shown) of the smartphone built-in processor. ). On the other hand, the fourth jack electrode J4 is connected to GND.

  In this way, in the CTIA standard and the OMPT standard, the meanings of the third jack electrode J3 and the fourth jack electrode J4 are opposite to each other. Appropriate considerations are required depending on whether it is a dedicated machine or a dual-purpose machine.

<About earphone device with flashing lamp>
An earphone device with a blinking lamp, which is an embodiment of a battery-less peripheral device according to the present invention, will be described.

1. External Configuration An external view of the earphone device with a flashing lamp is shown in FIG. As shown in FIG. 1, the earphone device 1 includes a case 11 in which circuit components and the like are built, a right earphone cord 12R and a left earphone cord 12L extending from the case 11, and tips of the earphone cords. A right earphone speaker 13R and a left earphone speaker 13L attached to the left earphone speaker, and a right LED lamp 14R and a left LED lamp 14L attached to the earphone speaker.

  As will be described later, the right earphone cord 12R includes an electric wire serving as a right sound signal line and an electric wire serving as a right lamp drive line. Similarly, the left earphone cord 12L includes a wire serving as a left sound signal line and a wire serving as a left lamp drive line.

  A four-pole phone plug P is integrally fixed to the case 11 so as to protrude from the case. In the four-pole phone plug P, a first plug electrode P1, a second plug electrode P3, and a third plug electrode P4 are arranged from the tip portion toward the root portion.

  When the 4-pole phone plug P is firmly inserted into the 4-pole phone jack J, the first plug electrode P1 is connected to the first jack electrode J1, the second plug electrode P2 is connected to the second jack electrode J2, and the third The plug electrode P3 is electrically connected to the third jack electrode J3, and the fourth plug electrode P4 is electrically connected to the fourth jack electrode J1.

2. Circuit configuration a. General Outline A circuit diagram of an earphone device with a flashing lamp is shown in FIG. As shown in the figure, the circuit unit of the earphone device with a blinking lamp includes a right earphone speaker 13R, a left earphone speaker 13L, a right LED lamp 14R attached to the right earphone speaker 13R, The left side LED lamp 14L attached to the left earphone speaker 13L, a switching unit 15, and a peripheral function realization unit 16 are schematically configured.

  The first plug electrode P1 is connected to one end of the right earphone speaker 13R via the first sound signal line 71 passing through the resistor R1, and the second plug electrode P2 is connected to the downstream via the resistor R2. The second sound signal line 72 is connected to the left earphone speaker 13L. On the other hand, the other ends of the right and left earphone speakers 13R and 13L are returned through a common line 73, and further branched into two, and then through coupling capacitors C6 and C7, respectively, to the third plug electrode P3. Are connected to the fourth plug electrode P4. In the figure, the resistor R5 is for causing the smartphone to recognize that a load equivalent to a capacitor microphone is connected to either the third plug electrode P3 or the fourth plug electrode P4.

b. Configuration of Switching Unit The switching unit 15 in this example is for making the apparatus 1 compatible with both a CTIA standard 4-pole phone jack and an OMPT standard 4-pole phone jack. Specifically, it is constituted by a diode bridge circuit (so-called full-wave rectification circuit) using four diodes D1 to D4.

  When the four-pole phone plug P of the device 1 is inserted into a CTIA-standard four-pole phone jack J, a predetermined low potential (GND) is applied to the third plug electrode P3 and a predetermined voltage is applied to the fourth plug electrode P4. The high side potential (VCC) of each appears. Then, a current path flowing in the order of the fourth plug electrode P4 → the diode D3 → the high potential side input terminal 61 of the peripheral function realization unit 16 is formed, and a predetermined high side potential (VCC− VBE) (VBE is a forward drop voltage of the diode D3 (for example, about 0.6 V)) appears. At the same time, a current path that flows in the order of the low potential side input terminal 62 of the peripheral function realization unit 16 → the diode D2 → the third plug electrode P3 is formed, and the low potential side input terminal 62 has a predetermined low side potential (GND + VBE). (VBE is a forward voltage drop of the diode D2) appears.

  When the 4-pole phone plug P of the device 1 is inserted into the OMPT standard 4-pole phone jack J, a predetermined high-side potential (VCC) is applied to the third plug electrode P3, and a predetermined voltage is applied to the fourth plug electrode P4. Low-side potential (GND) appears. Then, a current path that flows in the order of the third plug electrode P3 → the diode D4 → the high potential side input terminal 61 of the peripheral function realization unit 16 is formed, and a predetermined high potential (VCC-VBE) is formed in the high potential side input terminal 61. ) (VBE is a forward voltage drop of the diode D3). At the same time, a current path that flows in the order of the low potential side input terminal 62 → the diode D1 → the fourth plug electrode P4 of the peripheral function realization unit 16 is formed, and a predetermined low potential (GND + VBE) ( VBE is a forward voltage drop of the diode D2.

  Therefore, regardless of whether the standard of the 4-pole phone jack J on the smartphone side is the CTIA standard or the OMPT standard, a predetermined high potential (VCC-VBE) is applied to the low potential input end 62 at the high potential input end 61. Shows a predetermined low potential (GND). Therefore, assuming that VCC = 2.7V and GND = 0V, a potential difference 1 that functions as a DC power supply voltage is present between the high potential side input terminal 61 and the low potential side input terminal 62 of the peripheral function realization unit 16. 0.5V (= 2.7−0.6 × 2) is obtained.

c. Configuration of Peripheral Function Realization Unit Peripheral function realization unit 16 is roughly configured by a power supply generation unit, an amplifier circuit 16A, a binary / low band circuit 16B, and a booster circuit 16C.

  In this example, the power supply generation unit includes a capacitor C4 for stabilizing the power supply voltage against load fluctuations. Thereby, the fluctuation | variation of the power supply voltage resulting from the fluctuation | variation of the load by switching operation is suppressed.

  The amplification circuit 16A amplifies the synthesized sound signal extracted from the two downstream sound signal lines 71 and 72 through the resistors R6 and R7 and then extracted through the coupling capacitor C2. This is constituted by a grounded-emitter amplifier circuit including an NPN transistor Q1, a collector resistor R3, and a collector-emitter feedback resistor R8.

  The binarization / lowering circuit 16B, after being amplified by the amplifying circuit 16A, binarizes the synthesized sound signal extracted through the coupling capacitor C1 with a reference value, and also outputs a predetermined low-frequency component ( For example, in this example, a PNP transistor Q2, a collector-side capacitor C5 functioning as a low-pass filter, and a bias resistor are output.

The application program corresponding to the process shown in the figure is normally installed on the smartphone from the beginning of purchase, but for example, it can be downloaded from the Internet using a communication function, such as a home game machine. It can also be installed on electronic devices.

  In the figure, when the process is started, first, one of a plurality of musical tone data downloaded from the Internet and stored in the memory is selected through a predetermined selection operation on the smartphone (step 101). Then, it will be in the state which waits for the performance start of the said music (step 102, step 103 NO).

  In this state, when a predetermined operation on the smartphone is instructed to start the performance of the music (step 103 YES), a predetermined musical sound sample timing comes (step 108 YES), and the pointer for specifying read data is incremented. Each time (step 109), a pair of left and right musical sound data corresponding to the time-division instantaneous value of the left and right musical sounds at each sample timing is read from the memory (steps 104 and 106) and D / A conversion processing (step 105, step 105). 107) is repeated until the end of the performance (step 110 YES).
