(first embodiment)

As shown in fig. 1, the speech information processing apparatus 100 of present embodiment has shell 110, and this shell is used for holding therein: loud speaker 102 has the vibrating membrane that is used to export voice messaging; A pair of first and second Mikes (104,106), each microphone has the sound collecting part; And signal processing 108, be configured to handle the output signal of first and second microphones.Provide from the voice messaging of loud speaker 102 outputs to the external world by the transmission sound hole 112 that forms in the shell 110.Reference numeral 113 expression in the accompanying drawings is used to operate the action button of the communications status of speech information processing apparatus.Below describe each assembly in these assemblies in detail.

In the present embodiment, shown in Fig. 2 A and 2B, first microphone 104 remains between the vibrating membrane 120 of transmission sound hole 112 and loud speaker 102, makes the sound collecting part towards vibrating membrane 120.Second microphone 106 is arranged in the outside of periphery of the vibrating membrane 120 of loud speaker 102, makes the transmission sound hole 114 of sound collecting part by being used for microphone towards the outside.

First microphone 104 is capacitor type silicon microphones.As shown in Figure 3A and 3B, acoustical signal/electrical signal conversion portion C m1 comprise substrate 140, lower electrode 141, oscillating component 143, near the support part 145 that four angles of the periphery of oscillating component 143, forms at the silicon substrate that forms on the substrate 140, by polysilicon film formed upper electrode 42, at the insulating barrier 146 of cavity 144 that is provided with between lower electrode 141 and the upper electrode 142 and the SiN film between lower electrode 141 and upper electrode 142, placed.Insulating barrier 146 covers lower electrodes 141 except the whole basically surface the zone of oscillating component 143 below of upper electrode 142 and the zone that is used for terminal is connected to lower electrode 141 just in time almost.

In the accompanying drawings, the position that Reference numeral 147 is illustrated in the face of the center basically of oscillating component 143 is in the intercommunicating pore that forms in substrate 140 and the lower electrode 141, makes cavity 144 by intercommunicating pore 147 and external communications.Therefore, intercommunicating pore 147 usefulness act on and reduce in the vibration processes of oscillating component 143 because air pressure variations and the steam vent of the pressure that occurs in microphone.Reference numeral 148 is illustrated in the little opening that is used for collecting voice that forms in the oscillating component 143.In addition, the terminal 149 of the Au/TiW film that is connected with upper electrode 142 is formed at and supports on the part 145.Above-mentioned first microphone 104 has and does not use any directly bare chip structure of assembling IC chip that is encapsulated on the substrate 140.This structure is preferred for the thickness that reduces microphone.In the present embodiment, the sound of second microphone 106/electrical signal conversion portion C m2 has the bare chip structure identical with first microphone 104.

When from the outside when the microphone with above-mentioned configuration applies with the corresponding vibration of sound, 143 vibrations of the oscillating component of upper electrode 142 are to cause the variation of distance between oscillating component and the lower electrode 141.Therefore, owing to the variation of static capacity between the electrode (141,142) electric current appears.

The caused electric current of the variation of static capacity is by charge pump circuit, and for example the circuit conversion shown in Fig. 4 A becomes voltage, and this voltage is output to signal processing 108 as voice signal then.That is to say that second microphone 106 has constant-voltage circuit K1, this constant-voltage circuit K1 is formed by the chip IC that is used for working power voltage+V (for example 5V) is converted to constant voltage Vr (for example 12V).In first microphone 104, constant voltage Vr is applied to the series circuit of resistance R 11 and acoustical signal/electrical signal conversion portion C m1.Connection mid point between resistance R 11 and acoustical signal/electrical signal conversion portion C m1 is connected to the gate terminal of J-FET element S11 (being junction field effect transistor) by capacitor C11.The drain terminal of J-FET cell S 11 be connected to working power voltage+V and its source terminal by resistance R 12 ground connection.In this, J-FET element S11 is used for the electrical impedance conversion.The voltage of the source terminal of this J-FET element S11 is outputed to signal processing 108 as voice signal.

Similarly, in second microphone 106, constant voltage Vr is applied to the series circuit of resistance R 21 and acoustical signal/electrical signal conversion portion C m2.Connection mid point between resistance R 21 and acoustical signal/electrical signal conversion portion C m2 is connected to the gate terminal of J-FET element S21 (being junction field effect transistor) by capacitor C21.The drain terminal of J-FET element S21 be connected to working power voltage+V and its source terminal by resistance R 22 ground connection.In this, J-FET element S21 is used for the electrical impedance conversion.The voltage of the source terminal of this J-FET element S21 is outputed to signal processing 108 as voice signal.

J-FET element S11, resistance (R11, R12) and capacitor C11 be arranged near acoustical signal/electrical signal conversion portion C m1.Similarly, J-FET element S21, resistance (R21, R22) and capacitor C21 be arranged near acoustical signal/electrical signal conversion portion C m2.The reducing of S/N ratio that might suppress in these cases, the voice signal that first and second microphones (104,106) export separately.

Alternately, be used for that (Cm1, output Cm2) converts voltage signal to, and the circuit that then this voltage signal is offered signal processing 108 can provide by the circuit shown in Fig. 4 B with acoustical signal/electrical signal conversion part.This circuit has operational amplifier OP1.The reversed input terminal of operational amplifier OP1 is connected to the outlet side of acoustical signal/electrical signal conversion portion C m (being acoustical signal/electrical signal conversion portion C m1 or Cm2).The parallel circuits of resistance R 1 and capacitor C1 is connected between the reversed input terminal and lead-out terminal of operational amplifier OP1.Non-inverting input of operational amplifier OP1 is connected to ground level.The lead-out terminal of operational amplifier OP1 is connected to the gate terminal of J-FET device S1 (being junction field effect transistor) and the source terminal of J-FET device is connected to ground by resistance R 2.In this, J-FET device S1 is used for impedance transformation.The voltage of the source terminal of this J-FET device S1 is outputed to signal processing 108 as voice signal.When Vs is the voltage of source terminal of this J-FET device S1 and Q when being the quantity of electric charge of acoustical signal/electrical signal conversion portion C m, Vs=-Q/C1.Resistance R 1 is the resistance that is used for the DC level of stable output.

Preferably first and second microphones (104,106) each be by silicon substrate being carried out the chip of the so-called MEMS (MEMS (micro electro mechanical system)) that micromachined obtains.

Shown in Fig. 2 A and 2B, first microphone 104 is kept by the rectangle frame rib 115 that forms on the inner surface of the antetheca in the transmission sound hole 112 with shell 110.Rib 115 is arranged to towards the central lid 122 of the dome vibrating membrane 120 of the loud speaker that illustrates after a while.Placing first microphone 104 with following state makes oscillating component 143 (sound collecting part) towards central lid 122.Height H 1 from the inner surface of the antetheca of shell 110 to the upper surface that is arranged in first microphone 104 the rib 115 is substantially equal to keep the height H 2 on the maintenance surface of rib 116 to loud speaker from the inner surface of the antetheca of shell 110.Thus, can first microphone 104 and the vibrating membrane 120 of loud speaker 102 between the gap be set to minimum.In addition, (for example as the opening 117 of the air vent hole during the vibration of oscillating component 143

0.5mm) be formed in the antetheca of rib 115 and shell 110 so that be communicated with the intercommunicating pore 147 of first microphone 104.By using this structure, can collect reliably by first microphone 104 from the voice of loud speaker 102 outputs.

In addition, second microphone 106 is being arranged on the inner surface of the antetheca of shell 110 in the cover 130 that forms at a side place of loud speaker, with not towards the vibrating membrane 120 of loud speaker 102.In addition, the position of oscillating component (sound collecting part) 143 is defined as towards the inner surface of the antetheca of shell 110 by rectangle frame rib 118.Formation is cut apart plate 132 with from covering 130 the inner surface rear extension to second microphone 106.Rib 134 with L shaped cross section is formed on the rear surface of cutting apart plate 132.The IC encapsulation 150 that comprises signal processing 108 is assemblied on this rib 134.Placing IC encapsulation 150 makes the rear surface contact of IC encapsulation cover 130 inner surface.

Second microphone 106 is electrically connected to IC encapsulation 150 by the conductive pattern PT on the inner surface that is formed at shell 110.The method that forms conductive pattern PT below is described tout court.In the present embodiment, by using MID (Molded Interconnect Device, mold interconnecting device) technology to form conductive pattern PT.That is to say that the zone that forms the part of conductive pattern PT on the inner surface that comprises the antetheca that is used for the shell 110 made by synthetic resin forms the prime coat electrode (plating undercoat electrode) of conductive film.In this, the prime coat electrode does not need to have the pattern identical with conductive pattern PT.That is to say that it is important covering the entire portion that is used to form conductive pattern PT with conductive film.Then, come patterning prime coat electrode, make and isolate with other parts with the corresponding part of conductive pattern PT by laser emission.That is to say, remove the part of prime coat electrode along the outline line that limits conductive pattern PT.Then, by electroplating the thickness of the prime coat electrode that increases on the part that is used to form conductive pattern PT.At last, by the conductive film outside the etching removal conductive pattern PT.In this case, might form meticulous conductive pattern PT by using laser emission.In addition, compare, have the advantage that reduces number of parts and simplify device architecture with the situation that is individually formed the wiring that is used for the transmission of power supply and signal.

In addition, when when on the inner surface of shell 110, forming the three-dimensional MID substrate that obtains that connects up according to the MID technology on, forming first microphone 104, can realize the further integrated of compact microphone.Can arrange that if desired a plurality of microphones are as second microphone 106.

Then, loud speaker 102 is described.Shown in Fig. 2 A and 2B, loud speaker 102 have by used thickness be 0.8mm based on the material of iron such as cold-rolled carbon steel plate (SPCC, SPCEN) and electromagnetism soft iron (SUY) form have the cylinder yoke 124 of opening at the one end.Arrange that in cylinder yoke 124 (for example relict flux density is 1.39T～1.43T) for the column permanent magnet 126 made by neodymium.As shown in Figure 5, yoke 124 is arranged in the inside of the holding member 128 with circular tubular shape, and the outer peripheral portion of dome vibrating membrane 120 is fixed to holding member 128.Vibrating membrane 120 can form as PET (polyethyleneterephthalate, polyethyleneterephthalate) and PEI (polyetherimide, Polyetherimide) by using thermoplastic resin material (for example thickness is 12 μ m～3 μ m).Tubular barrel 123 is fixed to the rear surface of vibrating membrane 120.By (for example twining polyurethane (polyurethane) copper cash around this tube 123

0.05mm) obtain voice loop 125.Tube 123 and voice loop 125 be arranged near the opening of yoke 124 with the direction of the paper perpendicular of Fig. 5 on can vibrate.

When in the polyurethane copper cash at voice loop 125 during input speech signal, because the magnetic field of the electric current of this voice signal and permanent magnet 126 and in voice loop 125, electromagnetic force occurs.This electromagnetic force makes coil 123 with vibrating membrane 120 vibrations.As a result, from the vibrating membrane 120 outputs voice corresponding with voice signal.For instance, loud speaker has the diameter of 20-25mm and the thickness of about 4.5mm.

As mentioned above, the rib 116 with L shaped cross section is formed on the inner surface in the face of the antetheca of the shell 110 of the vibrating membrane 120 of loud speaker 102 with tubular shape.The ledge of rib 116 is suitable for from the outer surface of the bossing 129 of the peripheral end side extension forwards of the holding member 128 of loud speaker 102.Therefore, loud speaker 102 can be placed to and make vibrating membrane 120 become face-to-face relation with the inner surface of the antetheca of shell 110.At this moment, between the inner surface of the vibrating membrane 120 of loud speaker 102 and shell 110, define the space that is used to hold first microphone 104.As shown in Figure 5, loud speaker 102 has in the mutual equally spaced position that makes progress in week and is in four attachments 121 that form on the outer peripheral portion.Loud speaker 102 is assemblied on the inner surface of shell 110 by the through hole that uses screw and be formed in the attachment 121.

As shown in Figure 6, the signal processing 108 that is contained in the IC encapsulation 150 comprises: amplifier section 152 is used for amplifying in noninverting mode the output of first microphone 104; Band pass filter 154 is used for removing the voice band (frequency noise outside 300～4000Hz) from the output of amplifier section 152; Delay circuit 156 is used for the output of delay bandpass filter 154; Amplifier section 151 is used for amplifying with phase inversion system the output of second microphone 106; Band pass filter 153 is used for removing the voice band (frequency noise outside 300～4000Hz) from the output of amplifier section 151; Adder circuit 157 is used for the output of band pass filter 153 is added to the output of delay circuit 156; And A/D change-over circuit 158, be used for the analog signal conversion from adder circuit 157 outputs is become digital signal.Delay circuit 156 can be constructed by time delay element or CR phase-delay network.

In Fig. 6, the A/D change-over circuit 158 that forms from the outlet side in signal processing 108 obtains voice signal so that analog signal conversion is become digital signal.Can provide A/D change-over circuit at the outlet side of each band pass filter (153,154).In this case, because subsequently processing carries out digital signal, so the operation of delay circuit 156 this advantage easily that becomes is arranged.

Below describe about the operation of signal processing 108.At first, it as X1 the distance between the center of first microphone 104 in the center of loud speaker 102 and the place ahead, center that is arranged in loud speaker 102 basically, and X2 be between the center of second microphone 106 of the center of loud speaker 102 and the periphery outside that is arranged in loud speaker 102 apart from the time, X1 is less than X2, and promptly (X1＜X2).Therefore, when the voice collected by first and second microphones (104,106) from loud speaker 102 outputs, the output M21 of second microphone 106 (Fig. 7 B) on amplitude less than the output M11 (Fig. 7 A) of first microphone 104, shown in Fig. 7 A and 7B.In addition, the phase place of the output M21 of second microphone 106 by with time of delay Td (=(X2-X1)/Vs) postpone, wherein Vs is the velocity of sound, (X2-X1) is the poor of distance between the loud speaker 102 and second microphone 106 and the distance between the loud speaker 102 and first microphone 104.

Then, poor (X2-X1) according to the distance between the distance between microphone 104 and the loud speaker 102 and microphone 106 and the loud speaker 102 carries out level adjustment, make the output level of two microphones (104,106) be equal to each other basically about voice from loud speaker 102 outputs.That is to say that shown in Fig. 8 A, amplifier section 152 generates output M12 by amplify output M11 in noninverting mode, and as shown in Fig. 8 B, amplifier section 151 generates output M22 by amplify output M21 in anti-phase (180 ° anti-phase) mode.In the present embodiment, the magnification ratio of amplifier section 152 is essentially 1.Therefore, can omit amplifier section 152.

Then, band pass filter (154,153) from output (M12 removes the frequency noise outside the voice band in M22), with generate the output shown in Fig. 9 A and the 9B (M13, M23).

Then, shown in Figure 10 A and 10B, the output delay of first microphone 104 that delay circuit 156 will be arranged near loud speaker 102 makes the output M14 of delay circuit 156 have the phase place identical with the output M23 of band pass filter 153 with Td time of delay.Then, calculate output (M14, M23) sum that obtains like this by adder circuit 157.As a result, might leave out and the corresponding signal component of exporting from loud speaker 102 of voice, shown in Figure 10 C, and obtain output Ma.Carry out under the situation of noninverting amplification at amplifier section 151 places, with the same in amplifier section 152, can be by after amplification procedure, carry out postponing step, calculating subtraction between the output signal of first and second microphones (104,106) then and offset and the corresponding signal component of voice from loud speaker 102 outputs.

In addition, delay circuit 156 can detect the phase difference between the output M23 shown in Fig. 9 B of the output M13 shown in Fig. 9 A of first microphone 104 and second microphone 106, and postpones the phase place of output M13 with the phase difference that is detected.At this moment, with poor (X2-X1) of the distance between the center of the center of distance between the center of the center of loud speaker 102 and second microphone 106 and loud speaker 102 and first microphone 104 be arranged so that output (M13, M23) phase difference between greater than 0 ° less than 90 °.Therefore, postponing in 0 ° to 90 ° scope by delay circuit 156 owing to export the phase place of M13, thus can easily determine phase difference, and the phase place of output is mated exactly mutually.

About the voice (communication speech) that the front side from speech information processing apparatus 100 provides, be arranged such that oscillating component (sound collecting part) 143 by transmission sound hole 114 towards the sound pressure of second microphone 106 of outside greater than being arranged such that the sound pressure of oscillating component (sound collecting part) 143 towards first microphone 104 of the vibrating membrane 120 of loud speaker 102.In addition, the output M21 of second microphone 106 on output level greater than the output M11 of first microphone 104.In addition, because the magnification ratio of amplifier section 151 is greater than the magnification ratio of amplifier section 152, so the output M22 of amplifier section 151 further increases than the output M12 of amplifier section 152.Therefore, in the output Ma of adder circuit 157, obtain and the corresponding output of voice.Therefore, in the output Ma of adder circuit 157, do not comprise and the corresponding signal component of exporting from loud speaker 102 of voice, and only can extract and the corresponding signal component of voice that partly provides to the sound collecting of second microphone 106 from the outside.

According to above-mentioned configuration, might prevent the phenomenon of uttering long and high-pitched sounds that when microphone 106 picks up the voice output of loud speaker 102, causes.In addition, owing to do not need big distance between loud speaker 102 and the microphone 106, so might reduce to have the size of the inside plant of speech information processing apparatus of the present invention.

The low AC voltage that AC/AC transducer 60 becomes frequency to increase the commercial AC power source conversion, and will hang down AC voltage and be applied to the coil 72 that is wound in around the core 70.DC power unit 61 is that internal circuit unit generates operating voltage from the stable dc voltage that obtains by rectification and level and smooth low AC voltage.Transceiver part 62 sends and receives information signal to realize the interactive type communication by information wire L2.E/O transducer 63 will convert light signal to from the information signal that information wire L2 receives, and by light emitting devices (LED) 64 output light signals.On the other hand, O/E transducer 65 is by the light signal that light receiving element (PD) 66 receives from outside as intercommunication unit 7 or functional unit 4 provides, and converts the light signal of reception to information signal, and information signal is sent to transceiver part 62.In the present embodiment, funtion part 67 is provided by supply socket.But if do not need omit function part 67.

In addition, can use another elementary cell 3 shown in Figure 14.This elementary cell 3 forms by door shell 31 and main casing 33, door shell 31 is made by synthetic resin and is had terminal (30a, 32a, a 30b that is connected to power line L1 and information wire L2,32b), main casing 33 is made and is detachably connected to functional unit 4 by synthetic resin.Door shell 31 and main casing 33 have module port 34 and modular connector 42 respectively, and module port 34 and modular connector 42 removably interconnect to set up simultaneously from door shell 31 to main casing 33 supply electric power and the transmission of signal therebetween.Replace main casing 33, the functional unit 4 with modular connector 42 can be detachably connected to the module port 34 of door shell 31.In this case, the door shell 31 with module port 34 can be considered as elementary cell.

Shown in Figure 15 B, the module port 34 that forms at the front surface of door shell 31 is provided with the information signal port 34b that is used to supply the electricity port 34a of electric power and is used for visit information line L2.In dual wiring system, module port 34 about the layout of electricity port 34a and information signal port 34b and shape by standardization (normalization).For example, shown in Figure 15 B, electricity port 34a and information signal port 34b dispose with the substantial rectangular shape separately, and are arranged parallel to each other.

On the other hand, as shown in Figure 14 and 15A, the modular connector 42 that forms in the rear surface of main casing 33 is provided with electric connector 42a and information signal connector 42b.In dual wiring system, modular connector 42 about the layout of electric connector 42a and information signal connector 42b and shape by standardization (normalization).For example, shown in Figure 15 A, electric connector 42a and information signal connector 42b dispose with the substantial rectangular shape separately, and are arranged parallel to each other.

In this embodiment, module port 34 has leader 35, as annular wall or the endless groove that extends around electricity port 34a and information signal port 34b.Form this leader 35 can joining bonding part 45 to, the annular wall of bonding part 45 as the modular connector 42 that on the rear surface of main casing 33, forms.Because by joining bonding part 45 to leader 35 simply, electric connector 42a and information signal connector 42b are connected to electricity port 34a and information signal port 34b simultaneously, so might improve the exchange easiness and the connection reliability of main casing 33.This configuration also can be used for having the functional unit 4 of modular connector 42.Module port 34 and modular connector 42 can pass through female connectors (female connector) and public connector (male connector) forms.

In addition, the elementary cell 3 of Figure 14 is designed to have sensor function or the controller function as funtion part 67.In addition, processing section 68 is formed between transceiver part 62 and the funtion part 67 as CPU and I/O interface 69.Processing section 68 has following function: the signal processing of carrying out the information signal that transceiver part 62 is received, the signal of handling being sent to funtion part 67, and receive the data-signal that provides from funtion part 67 so that it is exported as information signal by I/O interface 69.For applying the required electric power of voltage, transceiver part 62, processing section 68 and funtion part 67 provide from DC power unit 61.When being used for that when replacing AC/AC transducer 60 the commercial AC voltage transitions become the AC/DC transducer of required dc voltage, can omit DC power unit 61.Other circuit arrangement of Figure 14 is substantially the same with Figure 12, therefore omits repeat specification.

Functional unit 4 is designed to by using the electric power that provides by elementary cell 3 and the interactive type communication by elementary cell 3 and the information signal of information wire L2 that various functions are provided.For example, when functional unit 4 was connected near ceiling high relatively position and is assemblied in elementary cell 3 in the wall surface, it preferably had function of socket, safety function such as temperature sensor, motion sensor or monitor camera or audio-frequency function such as the loud speaker of admitting the plug that hangs with lighting apparatus.In addition, when functional unit 4 is connected to the user when easily the centre position of operating function unit is assemblied in elementary cell 3 in the wall surface, it preferably has the switching function of connection/shutoff lighting apparatus, the controller function that is used for electrical equipment such as air conditioning device or Presentation Function such as LCD.In addition, when functional unit 4 was connected near ground lower position and is assemblied in elementary cell 3 in the wall surface, it preferably had function of socket, audio-frequency function such as loud speaker or the footlights function of the plug that is used to admit electrical equipment such as Cyclonic vacuum cleaner.

Coil 72 usefulness of twining around core 70 in the elementary cell 3 shown in Figure 12 and 14 act on the supply unit that electric power is offered functional unit 4 from elementary cell 3 in the noncontact mode.That is to say that the coil 72 that twines of elementary cell 3 provides the electromagnetic coupled part corresponding with the primary side of transformer around core 70.On the other hand, as shown in figure 16, functional unit 4 has the electromagnetic coupled part that be included in the coil 82 that core 80 around twine corresponding with the secondary side of transformer.Therefore, by carrying out the electromagnetic coupled between elementary cell 3 and the functional unit 4, the low AC voltage of induction is to realize providing electric power from elementary cell 3 to functional unit 4 in the coil 82 of functional unit 4.In this embodiment, be higher than the low AC voltage of commercial AC voltage, so can reduce size as the electromagnetic coupled part of transformer owing to obtain frequency by AC/AC transducer 60.

In addition, the light emitting devices (LED) 64 of the E/O transducer 63 of elementary cell 3 is used in the noncontact mode light signal being sent to functional unit 4 as information signal.In this case, light receiving element (PD) 86 is arranged in the functional unit 4, makes when functional unit 4 is connected to elementary cell 3, and the light emitting devices 64 of elementary cell 3 concerns for 86 one-tenth face-to-face with the light receiving element of functional unit 4.Similarly, for light signal is sent to elementary cell 3 as information signal from functional unit 4, functional unit 4 has following light emitting devices (LED) 84, and this LED 84 concerns for 66 one-tenth face-to-face with the light receiving element (PD) of elementary cell 3 when functional unit 4 is connected to elementary cell 3.Therefore, elementary cell 3 and functional unit 4 have a pair of E/O transducer (63,83) and O/E transducer (65,85) separately as the optical coupling part that is used to be implemented in the interactive type communication of information signal therebetween.

Shown in Figure 12 and 13, the optical coupling part Y that is used to supply the electromagnetic coupled part X of electric power and be used for the interactive type communication of information signal is arranged in the side surface of elementary cell 3 with the required distance of each interval.The shape of electromagnetic coupled part X and optical coupling part Y is stylized (normalization), makes each elementary cell 3 be shared by a plurality of functional units 4.In addition, preferably as shown in figure 16 each side in the both sides of functional unit 4 a pair of electromagnetic coupled part X and optical coupling part are provided.That is to say, the optical coupling part Y that forms in a side of functional unit 4 (for example left side) comprises light receiving element 86 that is positioned at upside and the light emitting devices 85 that is positioned at downside, and comprises light emitting devices 94 that is positioned at upside and the light receiving element 96 that is positioned at downside at the optical coupling part Y that the opposite side (for example right side) of functional unit 4 forms.

In this case, a side of functional unit 4 is used for being connected with elementary cell 3, and the opposite side of functional unit 4 is used for being connected with another functional unit 4 (for example additional function shown in Figure 19).Therefore, when being connected in series to elementary cell 3, might guarantee a plurality of functional units 4 interactive type communication of information signal.Further preferably euphotic cover is attached to each optical coupling part Y with the protection optical device.As shown in figure 16, functional unit 4 have be used to realize supply of electric power and with the circuit unit of the interactive type communication of the information signal of adjacent function unit 4.These circuit units are substantially the same with the circuit unit of elementary cell 3, therefore omit repeat specification.

As shown in figure 13, front surface place in elementary cell 3 forms when funtion part 67 (for example supply socket), and when providing a pair of electromagnetic coupled part X and optical coupling part Y at the side surface place of elementary cell 3, functional unit 4 can be connected to elementary cell 3 along wall surface (promptly substantially parallel with wall surface).Therefore, might improve functional expansionary in the dual wiring system and attractive in appearance without detriment to the inner space.

Then, the intercommunication unit 7 that removably is attached to elementary cell 3 and/or functional unit 4 is described.The example of intercommunication unit 7 as shown in figure 17.As from then on being expressly understood among the figure, the intercommunication unit 7 of present embodiment has the assembly substantially the same with functional unit 4 except that following feature.That is to say, intercommunication unit 7 is characterised in that and comprises the funtion part 81 of speech information processing apparatus 100 of the present invention as functional unit 4, this speech information processing apparatus comprises loud speaker 102, a pair of microphone (104 of explanation after a while, 106) and signal processing 108, amplifier section 103 and echo eliminate part (105,107).Explanation about the functional unit except that funtion part 81 4 can be equally applicable to intercommunication unit 7, therefore omits repeat specification.

In intercommunication unit 7, according to the signal processing that in first embodiment, describes in detail, the output Ma of adder circuit 157 does not comprise and the corresponding signal component of voice from loud speaker 102 output basically in the signal processing 108 of Fig. 6, and the corresponding signal component of voice that partly provides with sound collecting to second microphone 106 only is provided.The output Ma of adder circuit 157 becomes digital signal by A/D change-over circuit 158 from analog signal conversion, outputs to echo then and eliminates part 107.Eliminate in the part 107 echo, the digital signal that provides from A/D change-over circuit 158 is stored in the memory, and the Digital Signal Processing of following explanation is carried out by CPU or DSP.

That is to say, echo is eliminated the output of part 107 receptions of echoes elimination part 105 as the reference signal, and the output of signal processing 108 further carried out arithmetical operation, make to offset the voice signal that when first and second microphones (104,106) pick up receiver voice from loud speaker 102 outputs, obtains.Therefore, even be retained in the output of signal processing 108 with the corresponding signal component of exporting from loud speaker of voice, the signal component of the reservation in the output of second microphone 106 also can be eliminated part 107 by echo and further be reduced.In addition, echo is eliminated the output of part 105 receptions of echoes elimination part 107 as the reference signal, and the output of I/O interface 89 carried out arithmetical operation, make and offset when first and second microphones pick up transmitter voice from loud speaker 102 outputs voice signal in another intercommunication unit 7 acquisitions.Therefore, the voice that provide from another intercommunication unit 7 can clearly be exported from loud speaker 102.Particularly, adjust echo by the variable attenuation device (not shown) that in following loop circuit, forms and eliminate part (107,105) be not more than 1 loop gain to have, this loop circuit comprises loud speaker 102-microphone (104,106)-signal processing 108-echo elimination part 107-I/O interface 89-echo elimination part 105-amplifier section 103-loud speaker 102.

According to above-mentioned dual wiring system with intercommunication unit 7, for example, the voice signal that sends by information wire L2 another intercommunication unit 7 from be installed on different rooms is eliminated part 105 by amplifier section 103 amplifications, then from loud speaker 102 outputs by echo.In addition, by operating operation button 113, intercommunication unit 7 is in the communication enabled state.The voice signal of being collected by microphone (104,106) is 108 processed in signal processing, send to then that echo is eliminated part 107 and send to another intercommunication unit 7 that is installed in the chummery not by information wire L2.That is to say, might provide have mutually away from the room between realize comfortable communication and the intercom system of this ability of phenomenon that prevents to utter long and high-pitched sounds.

The structure of acoustical signal-electrical signal conversion part is not limited to concrete structure.As described in first embodiment, for example when using by used thickness, compare with the situation of traditional electric capacitor microphone and can reduce the microphone size and to make it thinner to 2.5mm and the capacitor type silicon microphone that forms as the semi-conducting material of 2mm on one side.In addition, the number of acoustical signal-electrical signal conversion part is not limited to one.For example, in shell 190, can arrange four acoustical signals-electrical signal conversion part.In addition, when bias drive circuit K2, impedance inverter circuit K3 and A/D change-over circuit K4 form by single semiconductor integrated circuit, can further reduce the microphone size and make it thinner.Alternately, two circuit selecting from bias drive circuit K2, impedance inverter circuit K3 and A/D change-over circuit K4 can be formed to obtain same effect by single semiconductor integrated circuit.

As the variation of present embodiment, as shown in figure 37, the microphone that is formed by the module of incorporating circuit component into can be used as first and second microphones (104,106) of first embodiment.This microphone has the structure that obtains by pressure combined circuit accommodating layer 180 between the substrate 182 that is used for outside wiring pattern.

Can form circuit accommodating layer 180 by embedding semiconductor integrated circuit K5, peripheral part K6 and a plurality of path (internal path) 184, wherein integrated circuit K5 comprises bias drive circuit, impedance inverter circuit and A/D change-over circuit, (organic greensheet, OGS) the rectangle copper post in 186 provides path 184 by the organic tellite that contains the epoxy resin layer of filler on the base portion that comprises the PET film (base) and this base portion.In addition, semiconductor integrated circuit K5 has exposed electrodes part on its front surface and rear surface.By using path 184, might be omitted in the step that forms the through hole wiring in organic tellite 186.In each substrate 182, it is on the front surface and rear surface of insulated substrate of RF-4 core material of 100 μ m that the copper wiring case is formed at as thickness.Substrate 182 is electrically connected to exposed electrodes part on the front surface of semiconductor integrated circuit K5 and rear surface.

Wherein " E " is the Young's modulus of oscillating component 143, and " ρ " is Poisson's ratio.

About the sensory characteristic of capacitor type microphone, always need obtain even or smooth sensitivity at the frequency band that is lower than this fundamental resonance frequency " fo ".For example, when first microphone 104 detected acoustical signal in the zone of audibility, it was just enough to obtain smooth sensitivity in the audio-band of 50Hz-16KHz.On the other hand, when the acoustical signal in first microphone, the 104 detection supersonic zone, need to reduce the radius " a " of oscillating component 143 in higher frequency field, to obtain smooth sensitivity.For example, Figure 38 shows when using " a1 " (representative dimensions), " a1 * 4/5 ", " a1 * 3/5 " and " a1 * 2/5 " as the radius " a " of oscillating component 143, by using the variation of the relative sensitivity of simplifying the simulation model estimation.In Figure 38, characteristic D1 is the situation of " a1 " corresponding to radius " a ", characteristic D2 is the situation of " a1 * 4/5 " corresponding to radius " a ", and characteristic D3 is the situation of " a1 * 3/5 " corresponding to radius " a ", and characteristic D4 is the situation of " a1 * 2/5 " corresponding to radius " a ".Therefore, along with the radius " a " of oscillating component 143 reduces, might obtain smooth and sufficient sensitivity at higher frequency band.

On the other hand, when the radius " a " of oscillating component 143 when reducing, the rigidity of oscillating component 143 increases.In this case,, oscillating component 143 is difficult to vibration, so sensitivity trends towards reducing because becoming.There is following method to reduce: to increase bias voltage to acoustical signal-electrical signal conversion portion C m1 applies in order to prevent sensitivity, fundamental resonance frequency " fo " at oscillating component 143 " reduce the thickness " b " of oscillating component 143 in the scope that do not reduce, and change the gap between oscillating component 143 and the lower electrode 141.Alternately, when a plurality of trickle opening (not shown) that in lower electrode 141, is formed for ventilating, can be by regulating sound characteristics with trickle opening control acoustic resistance.
