Description

  The present invention relates to a pickup cartridge, for example, to a pickup cartridge that reads an audio signal from an analog record.

  In playback of an analog record, a pickup cartridge is used to pick up an audio vibration inscribed on the analog record placed on a turntable. The pick-up cartridge is attached to the tone arm, and the sound vibration picked up by the pick-up cartridge is transmitted through the cantilever. Then, the sound vibration is converted into the electric vibration by the power generation element attached to the cantilever, and the sound is reproduced by the audio device.

  Here, the type of pickup cartridge will be described. There are two types of pickup cartridges: speed proportional and amplitude proportional.

  The speed proportional type pickup cartridge has a moving coil type which transmits vibration to the coil and converts the speed displacement of the coil into an electric signal, and a moving magnet type which transmits vibration to the magnet and converts the speed displacement of the magnet into an electric signal. . In this speed proportional type pickup cartridge, it is necessary to attach a coil or a magnet to the cantilever and to fit in the gap of the magnetic circuit, and the shape is restricted.

  The amplitude proportional type pickup cartridge is a crystal cartridge that detects vibration using Rochelle salt. In this amplitude proportional type pickup cartridge, the magnitude of vibration given to Rochelle salt is converted into an electric signal. The amplitude proportional type pickup cartridge is suitable for mass production due to its simple structure, but has a problem of insufficient frequency characteristics.

  From the above description, it can be seen that the speed proportional pickup cartridge is suitable when reproducing an analog record with high sound quality. However, in the velocity proportional type, since it is necessary to attach a heavy member such as a coil or a magnet to the cantilever, the weight of the cantilever is increased, the control of the vibration damping rate of the cantilever is difficult, and the sound quality is degraded. Then, the technique which suppresses the vibration of a cantilever to patent document 1 is disclosed.

  The technology described in Patent Document 1 includes a cantilever having at one end side a reproduction needle for tracing the sound groove of the record board R, and at the other end side integrally having a vibrator acting on an electrical transducer for audio signal output. In a pickup cartridge in which the other end side of the cantilever and the vibrator are vibratably supported by the cartridge body via a damper material, an electrorheological fluid (ER fluid) whose viscosity is changed by an applied voltage is used as the damper material.

  However, even if the technology described in Patent Document 1 is used, there is no change in the basic structure using the conventional pickup method, there is a limit in the degree of sound quality improvement, and there is a problem that further sound quality improvement is difficult.

  The present invention has been made in view of the above circumstances, and it is an object of the present invention to improve the sound quality in the reproduction of an analog record.

  In one aspect of the pickup cartridge of the present invention, a cartridge base member attached to a tone arm, and a cartridge base member attached to the surface facing the analog record with the cartridge base member attached to the tone arm A pick-up element for picking up, and the cartridge base member transmitting the vibration picked up by the pick-up element, and a first opening provided on the side of the sound conduit on which the pick-up element is provided And an elastic member for supporting the pickup element and transmitting the vibration picked up by the pickup element to the sound conduit, and a second member provided opposite to the side of the sound conduit on which the pickup element is provided. And a microphone provided to close the opening.

  The pickup cartridge according to the present invention can convert the vibration picked up by the stylus into an electric signal regardless of the vibration of the tone arm, because the microphone converts the vibration picked up by the stylus.

  The pickup cartridge of the present invention can improve the sound quality in reproduction of an analog record.

  In the turntable on which the pickup cartridge 1 according to the first embodiment is attached, the tone arm has a main function of supporting the pickup cartridge 1. On the other hand, in the pickup cartridge 1 according to the first embodiment, the sound vibration picked up from the analog record by the pickup element 12 is converted into an electric signal by the microphone 14 and the conversion circuit provided in the subsequent stage using the wiring 15 and the cartridge terminal 16 Reproduction is performed by an electric signal processing circuit such as an amplifier. Here, as the microphone 14, for example, one that converts a minute displacement amount of a sound receiving surface such as a condenser microphone to an electric signal is preferable. In addition, the electric signal processing circuit provided at the rear stage of the pickup cartridge 1 may include a microphone amplifier or the like for amplifying an audio signal from the microphone 14. In addition, it can replace with the microphone 14 and can also use a piezoelectric element as a sensor.

  The detailed configuration of the pickup cartridge 1 according to the first embodiment will be described below. As shown in FIG. 1, in the pickup cartridge 1 according to the first embodiment, the pickup element 12 is provided on the surface facing the analog record in a state where the cartridge base member 10 is attached to the cartridge member. Then, the pickup element 12 picks up the vibration from the analog record.

  Therefore, a support mechanism of the pickup element 12 in the pickup cartridge 1 according to the first embodiment will be described with reference to FIG. FIG. 2 is a view for explaining the structure of the mounting portion of the pickup element 12 of the pickup cartridge according to the first embodiment.

  Further, as shown in FIG. 2, the cartridge base member 10 has a ground support portion 31. The ground support portion 31 supports the ground end 23 of the pickup element 12. The elastic member 13 supports a portion (for example, the cantilever 22) of the pickup element 12 between the stylus 21 and the ground end 23 via the pickup support member 24. Thus, the pickup element 12 vibrates with the ground end 23 in contact with the ground support portion 31 as a central point.

  In the pickup cartridge 1 according to the first embodiment, the vibration of the pickup element 12 is guided by the elastic member 13 to the sound conduit provided in the cartridge base member 10, and the vibration transmitted through the sound conduit is converted to the electric signal by the microphone 14.

As shown in FIG. 3, in the pickup cartridge 1 according to the first embodiment, when the cartridge base member 10 is viewed from the projecting direction of the stylus 12, two sounds are located at symmetrical positions with respect to the supporting point of the stylus 12. Conduits (sound conduits 41a, 41b in FIG. 3) and two microphones (microphones 14a, 14b in FIG. 3) are provided. Then, the position and the angle are adjusted so that the center line of the sound conduit 41 a in the extension direction of the cylinder and the center line of the sound conduit 41 b in the extension direction of the cylinder intersect at the center point of the cantilever 22. The angle θ between the horizontal line passing through the center point of the cantilever 22 and the center line of the tube of the sound conduit 41a and the angle θ between the horizontal line passing through the center point of the cantilever 22 and the center line of the tube of the sound conduit 41b are 45 °. Set to The angle and position of the sound conduit are the positional relationship necessary for guiding the vibration of the unevenness carved in the sound groove of the record to the microphones 14a and 14b provided on the left and right of the cantilever 22. In the example shown in FIG. 3, two sets of the sound conduit and the microphone are shown. However, when performing monaural reproduction, this may be configured as only one set.

  The sound conduits 41 a and 41 b have a cylindrical structure for transmitting the vibration picked up by the pickup element 12. Further, as shown in FIG. 3, the elastic member 13 closes the first opening provided on the side of the sound conduits 41a and 41b on which the pickup element 12 is provided, and supports the pickup element 12 so that the stylus The picked up vibration is transmitted to the sound conduits 41a and 41b.

The microphone 14 b is provided so as to close a second opening provided on the sound conduit 41 b opposite to the side where the stylus 12 is provided.

  Here, the elastic member 13 needs to have elasticity in order to guide the vibration of the stylus 12 to the sound conduits 41a and 41b, but its rigidity needs to have a predetermined rigidity. As the elastic member 13, for example, a resin having a predetermined hardness such as silicone rubber is suitable.

  Further, as shown in FIG. 3, the pickup support member 24 is supported by the elastic member 13 and supports the pickup element. In addition, the pickup support member 24 has a surface perpendicular to the center line of the sound conduit 41 in the extension direction of the cylinder. The sound conduit 41 and the microphone 14 are symmetrical so that the center lines of the extension direction of the tube of the sound conduit 41 intersect at the center point of the pickup element when the cartridge base member 10 is viewed from the protruding direction of the pickup element. Two are provided at the position.

  In addition, the relationship between the size of the second opening of the sound conduit and the sound receiving surface of the microphone also has one feature, and therefore, referring to FIG. 4, the area of the second opening of the sound conduit and the sound receiving The relationship with the area of the surface will be described.

  Here, in the electric signal output from the pickup cartridge 1 according to the first embodiment, one of the sounds of the left and right channels is a reverse phase signal. Therefore, the signal that is in the opposite phase is inverted using a conversion circuit and then input to the microphone amplifier. First, the cartridge terminal 16 provided in the pickup cartridge 1 will be described. FIG. 6 is a view for explaining the assignment of the terminals 16 of the cartridge according to the first embodiment.

  As shown in FIG. 6, the pickup cartridge 1 according to the first embodiment has a left channel positive electrode terminal T1, a right channel positive electrode terminal T2, a negative electrode terminal T3, and a microphone power supply terminal T4 as the cartridge terminals 16.

Therefore, a conversion circuit is provided between the pickup cartridge 1 and the microphone amplifier, and conversion is performed so that the signals of the left and right channels become positive phase signals by this conversion circuit. Therefore, FIG. 7 shows a circuit diagram of the conversion circuit. In the example shown in FIG. 7, since the right channel sound signal is an antiphase signal, the conversion circuit inverts the phase of the right channel sound signal.

  From the above description, the pickup cartridge 1 according to the first embodiment transmits the vibration picked up by the pickup element 12 from the analog record to the microphone 14 via the sound conduit 41 sealed by the elastic member 13 and the microphone 14. Thereby, in the pickup cartridge 1 according to the first embodiment, the vibration of the pickup element 12 is transmitted to the microphone 14 without the noise caused by the weight of the tone arm and the pickup cartridge and other vibrations being superimposed, and an electric signal Converted to That is, in the pickup cartridge 1 according to the first embodiment, using the microphone 14 as the power generation element does not receive the influence of the natural vibration of the power generation element, so the damper can be simplified and the frequency characteristic is improved. it can.

  In the pickup cartridge 1 according to the first embodiment, with such a configuration, by converting vibration into an electrical signal, it is difficult for other pickup cartridges to realize such as rising of bass, high-pitched sound, high resolution sound, etc. A sound quality audio signal can be obtained. Although it is difficult to analyze such characteristics by frequency analysis of the audio signal taken out of the pickup cartridge, it has been verified by the inventors of the present invention that an improvement which can be clearly recognized in terms of hearing can be obtained.

  In the pickup cartridge 1 according to the first embodiment, it is not necessary to put a coil or a magnet in the magnetic gap as a power generation element, and structural restriction is reduced, so that the tracing ability of the stylus 22 can be enhanced.

  In the pickup cartridge 1 according to the first embodiment, a condenser microphone is used as the microphone 14. By using the condenser microphone in this manner, the sound signal output from the pickup cartridge 1 has an amplitude proportional type characteristic. Here, in the case of the amplitude proportional type pickup cartridge, it is general to perform equalizing processing of about ± 20 dB in the rear stage circuit and about ± 39 dB in the speed proportional type pickup cartridge. However, in the pickup cartridge 1 according to the first embodiment, the equalizing effect by the fluid can be obtained in the pickup cartridge. Therefore, when the pickup cartridge 1 according to the first embodiment is used, it is confirmed by a verification that there is no problem even if the sound signal output from the pickup cartridge 1 is input to the power amplifier without performing equalization processing. The As described above, by omitting the equalizing process, the sound system using the pickup cartridge 1 according to the first embodiment can realize higher sound quality.

Thereby, in the pickup cartridge 1 according to the first embodiment, the transmission of the vibration to the microphone 14 is in a transmission form using air (that is, fluid). By performing vibration using such fluid, the efficiency of impedance matching can be improved, and the amplitude of the output voltage is about 30% higher than the amplitude of the output voltage output from the other amplitude proportional type pickup cartridge can do. By obtaining such a large output voltage amplitude, it is possible to reduce the dependence on the amplifier provided in the subsequent stage, and to realize a natural reproduced sound. Even when a fluid such as air is used to transmit the vibration, a peak appears in the frequency characteristic, but the peak can be removed from the human audible range by adjusting the length of the sound conduit 41.

  Further, in the pickup cartridge 1 according to the first embodiment, the area of the second opening provided on the microphone side of the sound conduit 41 is set smaller than the area of the sound receiving surface of the microphone 14. Thereby, in the pickup cartridge 1, the vibration transmitted to the microphone 14 can be artificially amplified, the vibration detection accuracy in the microphone 14 can be improved, and the output signal amplitude can be increased.

  Further, in the pickup cartridge 1 according to the first embodiment, two sets of sound conduits and microphones are provided so as to be symmetrical with respect to the support point of the pickup element 12. Thereby, in the pickup cartridge 1 according to the first embodiment, stereo reproduction becomes possible.

  The present invention is not limited to the above embodiment, and can be appropriately modified without departing from the scope of the present invention.
