SOUND PICK-UP AND SOUND MODIFYING DEVICE WITH INTERNAL
COMPONENT PLATFORM FOR REMOVABLE ATTACHMENT TO ACOUSTIC
MUSICAL INSTRUMENT
TECHNICAL FIELD
The present invention relates to a removable and exteriorly mountable sound pick-up and sound modifying device that is attachable to an acoustic musical instrument without having to modify the sound box of the instrument or connecting electronic devices thereto or interfering with the sound hole of the sound box.
BACKGROUND OF THE INVENTION
It is known in the art to interface electric stringed instruments such as electric guitars to electronic systems to amplify and an modify the sound of the instrument by playing music with the strings of the instrument. Such instruments are also provided with a multitude of controls mounted on the body of the instrument, such as a volume knob, tone knobs, jacks, a pick-up selector and analog vibration pickups to detect string vibrations and convert the vibrations into electronic sound signals which are then mixed and amplified to generate synthesized musical sounds.
Various electronic devices have been adapted to the sound box and sound hole of acoustic stringed instruments in an attempt to amplify and modify the sound of the instrument in a similar fashion as the electric stringed instruments. However, with acoustic musical instruments it is important that the quality of the soundbox of the instrument not be affected by such devices as it is the part of the instrument that generates the quality of the sound produced by the sound vibration of the strings. A
quality acoustic musical instrument may also be very costly due to its construction and the quality of its material and workmanship. It is therefore very important not to modify the soundbox or interfere with sound hole of the instrument, as well as the bridge connected to the top soundboard, by securing objects to the outer and/or inner surface of the soundbox or modify the bridge and saddle on the top soundboard or interfere in anyway with the sound hole.. Known devices are usually permanently secured to the acoustic musical instrument and does not permit removal thereof or ease of removal should the user person wish to play the instrument with its natural sound.
This is particularly so with an expensive acoustic musical instrument.
With reference to US Patent No. 5,614,688 there is disclosed the attachment of electronic components to the sound box of a violin or acoustic guitar with the pick-up cable extending in the body of the sound box and connecting to a jack secured to the body of the sound box. Therefore, the installation of such devices requires modification to the top soundboard and requires the attachment of a transducer assembly which interferes with the sound hole thereby obstructing the sound escaping from the sound box of the instrument which is no longer the natural sound of the instrument.
US Patent 8,907,200 describes a transducer mounting kit which is installed in the sound hole of an acoustic guitar. Such kit is elaborate and results in a complete transformation of the guitar with the soundbox characteristics completely modified as well as the sound emanating therefrom.
The use of transducers as sensors for detecting vibrations in an acoustic musical instrument such as a guitar is well known in the art, but again these installations require modifications to the sound box and/or the sound hole thereof. A
furhter example thereof is made with reference to US Patent Publication 2010/0218665 wherein hard dense timber braces are secured in a certain disposition to the inner surface of the top sound board of the sound box by such means as glue and a transducer is secured to one of the braces by a nut and bolt assembly. Such inner assembly is said to more readily transmit the detected vibrations to the transducer. The brace and the transducer may also be of a unitary construction. The transducer also has a cable, not shown but obvious , to connect to a jack which is obviously secured to the body of the instrument to output its detected signals to a remote device for sound amplification and/or modification. Again, a permanent modification is made to the acoustic sound box affecting its natural sound and such modification is permanent which mmeans that the instrument is not intended to be played as a conventional guitar generating a natural sound from the acoustics of its sound box.
US Patent Publication 2014/0224099 describes a sound augmentation and mixing system for an acoustic musical instrument such as an acoustic guitar.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to the drawings and more particularly to Figure 1, there is shown generally at 10 an acoustic guitar musical instrument to which is mounted the removable sound pick-up and sound modifying device 11 of the present invention. It is pointed out that the configuration of the embodiment of the device 11 described herein is not mountable on certain other type acoustic musical instrument without modifications thereto, where possible, and may result in a quite different than the one illustrated herein.
The present embodiment was developed specifically for an acoustic guitar 10 and as herein illustrated it is comprised of a sound box 12 having a top sound board 13 with a sound hole 14 through which sound produced by vibrating the strings 15 will escape from the sound box after having been acoustically modified by the sound box.
Of course, the quality of the material forming the sound box and the expert workmanship in its construction will have an effect on the quality of the natural sound produced by the sound box. The sound box 12 has a surrounding sidewall 16 and a back board 17.
The strings 15 are mounted under tension between tensioning pegs, not shown but obvious to a person skilled in the art, mounted at a top end of the neck 18 and an attachment block 19 mounted rearwardly of the saddle and bridge assembly 20 secured rearwardly of the sound hole 14 and better illustrated in Figure 4.
With additional reference to Figures 2 to 6 there is now described the construction and operation of a fist embodiment of the sound pick-up and sound modifying device 11 of the present invention. The device 11 is formed with a support platform 21 on which can be mounted electronic circuit boards 22 and electronic chips 23, such as Blue Tooth or USB chips. The support platform 21 is molded from suitable plastics material and has a back wall 24 formed with holes 25 or cavities 26 adapted for the mounting of different type connectors such as USB port connectors or plug connectors to connect the circuit components mounted in the device to remote devices such as sound amplifiers and speaker housings. The support platform 21 is also formed with a front abutment wall 27 for a purpose as later described. A removable or permanently securable cover 28 is detachably secured over the support platform or permanently fused welded thereover. By making the cover removable ease of access to the circuitry and hardware is provided for modification or repair thereof.
The cover 28 is formed with a rear wall 29 having a cavity 30 complimentary to the cavity 26 to form a securement for an attachment end 31' of an internal cylindrical connector 31 which may house electronic components and provide a direct connection to a transducer assembly 32. A 9 volts battery 33 provides the power supply for the circuitry housed on the platform and the transducer 34. An access opening 35 is formed in the support platform 21 for access to the battery for replacement. A
detachable door 36 closes the opening 35. The opposed sidewalls 37 of the cover 28 may be provided with indentations 38 for receiving a removable and adjustable attachment for supporting an iphone on the top surface 39 of the cover 28. The support platform 21 and the cover 28 constitutes a housing. The open front end of the cover 28 is provided with posts 29' aligned with the connecting arms 62 of the sound captor 60, as will be described later, to prevent the captor 60 from detachment over the front abutment wall 27.
As shown in Figures 3 and 5, the support platform 21 is adjustably secured to a clamp support 40. The clamp support 40 is also molded from plastics material and is formed as an L-shaped clamp support defining a flat support slide wall 41 sliddingly coupled to the support platform 21, and a rear downwardly extending and substantially transverse abutting end clamp wall 42. The end clamp wall 42 is formed with spaced leg formations 43 each having a cushion foam pad 44 glued thereover not to scratch the side wall of the acoustic musical instrument to which it is clamped on. A
pair of spaced apart spacer ribs 45, as shown in Figures 2 and 5, are formed on the outer face 46 of the clamp support slide wall 41 to support the clamp wall outer face 46 elevated from the top surface 13' of the top soundboard 13 with as little contact as possible not to affect the natural sound of the sound box 12. It is important with the present invention to provide a sound pick-up and sound modifying device incorporating a component mounting platform and wherein the device can be easily attached and detached to an acoustic musical instrument, herein a guitar 10, whereby the instrument can be played in its natural unaltered state or in a modified state to generate a modified sound by attaching the device of the present invention thereto.
With additional reference to Figure 6, the sliding adjustable attachement of the slide wall 41 with the support platform 21 is constituted by providing opposed elongated parallel channels 50 in the outer face 46 of the support platform 21 with equidistantly spaced side notches 51 for engagement with one or two tooth formations 52, see Figure 6, formed in opposed flexible finger engaging arms 53 integrally formed with the clamp support 40. This is a well known type of adjustable connection. The clamp support 40 also has an open-end cavity 54 formed therein for the passage of one or more vibrating sound transmitting speakers 55 securable to the outer face 46 of the support platform.
With reference to Figures 1 and 4, there will be described the construction and operation of the sound captor 60. The sound captor 60 is integrally formed from a flat rigid metal sheet to define a transverse bridge section 61 with rearwardly extending opposed spring connecting arms 62. Three saddle abutting formations 63 depend forwardly and downward of the transverse bridge section 61 for abutment against a forward face 58 of the saddle 56 secured to the bridge 57 and affixed to the top sound board 13 of the guitar 10 behind the sound hole 14, as illustrated. Each of the saddle abutting formations 63 has a forwardly projecting bottom extension section 64 having opposed transversely extending string contacting finger 65 lying in a common horizontal plane for contact engagement with the underside of the strings15 of the guitar and forwardly of the saddle 56 to pick up the sound vibrations in the strings 15 when vibrated. A tension coil spring 65 is secured at a rear attaching end 65' thereof to a post 66 formed with and projecting from the top surface 46' of the platform 21, and at a forward attaching end 65" to a hole 62' formed near the free end of an associated one of the spring connecting arms 62. As shown, there are two springs 65 connected to a respective one of the spring connecting arms 62 to bias the transverse bridge section 61 of the sound captor 60 against the front abutment wall 27 of the platform 21.
As shown more clearly in Figures 3 and 4, the transducer 32, which is an off the shelf transducer, is formed as an elongated metal rod and it is secured captive on the top surface of the transverse bridge section 61 by a non-metallic body 70, which could be formed in sections, disposed on top of the transducer 32, and an elongated bottom support cap 71 having opposed attaching fingers 72 to engage opposed end cavities 73 of the body 70. A thin damping spacer 74 is secured to the top surface of the transverse bridge section 61 to prevent metal-to-metal contact between the metal transducer and the bridge section 61 which is also metallic. The spacer 74 is constructed of tusk but other suitable material may be used, such as ivory, wood or combinations thereof or any other suitable non-metallic damping material.
The device of the present invention is mounted on the guitar 10 by firstly positioning the sound captor arms 63 between pairs of corresponding strings 15 and the abutting formations 63 disposed against the front face 58 of the saddle 56, as shown in Figure 4. The device or housing is then pulled back to stretch the springs whereby the front abutment wall 27 of the platform, as shown in phantom lines, is space rearwards of the saddle 56. The clamp leg formations 43 are then positioned to rest against the top portion of the rear end of the guitar side wall 16, as shown in Figure 1.
The sound wave vibrations from the strings picked up by the transducer through the sound captor are converted into corresponding electrical signals which are inputted via wire connection 75 into local circuitry mounted on the support platform 49 for local amplification and/or mixing and for retransmission back into the sound box 12 through small speakers or vibrators 55 to mix with the sound vibrations of the strings transmitted into the sound box through the saddle to produce a modified sound coming out of the sound hole 14. In this embodiment the speakers 55 would be resting on the top sound board 13. Alternatively, the sound signals from the local circuitry 22 mounted on the platform 21 could be transmitted back into the sound box by electrical connections 85 from the internal circuitry to the spring connecting arms 62 of the sound captor 60. The output sound signals from the transducer 34 may also be transmitted wirelessly by internal circuitry or conventionally though a plug jack 76 to a remote amplifier or sound processor and speaker system or simply for recording.
As illustrated in Figure 3 a USB and Blue chip component is mounted on the support platform 21 to input programmed sound signals into the device from an iphone which can be attached to the top surface of the housing cover 28, as shown in Figure 1.
The iphone 77 as shown in Figure 1 is attached by a double adhesive tape not shown.
A USB connector cable 78 may also provide the communication link between the iphone 77 and the circuits mounted on the platform.
Referring now to Figure 7 there is illustrated another embodiment of the device of the present invention wherein the tension springs 65 of the Figure 3 embodiment are replaced by long reverberating tension springs 80. The reverberating springs 80 are attached at their rear hook end 81 to lugs 82 formed integral with the rear wall 24 of the platform 21. The front end of the springs have their hook end 83 attached to the spring connecting arms 62 of the sound captor 60. Accordingly, the springs 80 which are in tension with the sound captor 60 create reverberating sound or echos of the natural sound vibrations transmitted into the captor by the plucking of the strings of the instrument to modify the sound vibrations captured by the transducer and also transmitted back into the sound box of the guitar through the saddle and bridge in contact with the top soundboard and into the sound box and thus modifying the sound coming out of the sound hole.

The opposed sidewalls 37 of the cover 28 may be provided with indentations 38 for receiving a removable and adjustable attachment for supporting an iphone on the top surface 39 of the cover 28. The support platform 21 and the cover 28 constitutes a housing. The open front end of the cover 28 is provided with posts 29' aligned with the connecting arms 62 of the sound captor 60, as will be described later, to prevent the captor 60 from detachment over the front abutment wall 27.
As shown in Figures 3 and 5, the support platform 21 is adjustably secured to a clamp support 40. The clamp support 40 is also molded from plastics material and is formed as an L-shaped clamp support defining a flat support slide wall 41 sliddingly coupled to the support platform 21, and a rear downwardly extending and substantially transverse abutting end clamp wall 42. The end clamp wall 42 is formed with spaced leg formations 43 each having a cushion foam pad 44 glued thereover not to scratch the side wall of the acoustic musical instrument to which it is clamped on. A
pair of spaced apart spacer ribs 45, as shown in Figures 2 and 5, are formed on the outer face 46 of the clamp support slide wall 41 to support the clamp wall outer face 46 elevated from the top surface 13' of the top soundboard 13 with as little contact as possible not to affect the natural sound of the sound box 12. It is important with the present invention to provide a sound pick-up and sound modifying device incorporating a component mounting platform and wherein the device can be easily attached and detached to an acoustic musical instrument, herein a guitar 10, whereby the instrument can be played in its natural unaltered state or in a modified state to generate a modified sound by attaching the device of the present invention thereto.
With additional reference to Figure 6, the sliding adjustable attachement of the slide wall 41 with the support platform 21 is constituted by providing opposed elongated parallel channels 50 in the outer face 46 of the support platform 21 with equidistantly spaced side notches 51 for engagement with one or two tooth formations 52, see Figure 6, formed in opposed flexible finger engaging arms 53 integrally formed with the clamp support 40. This is a well known type of adjustable connection. The clamp support 40 also has an open-end cavity 54 formed therein for the passage of one or more vibrating sound transmitting speakers 55 securable to the outer face 46 of the support platform.
With reference to Figures 1 and 4, there will be described the construction and operation of the sound captor 60. The sound captor 60 is integrally formed from a flat rigid metal sheet to define a transverse bridge section 61 with rearwardly extending opposed spring connecting arms 62. Three saddle abutting formations 63 depend forwardly and downward of the transverse bridge section 61 for abutment against a forward face 58 of the saddle 56 secured to the bridge 57 and affixed to the top sound board 13 of the guitar 10 behind the sound hole 14, as illustrated. Each of the saddle abutting formations 63 has a forwardly projecting bottom extension section 64 having opposed transversely extending string contacting finger 65 lying in a common horizontal plane for contact engagement with the underside of the strings15 of the guitar and forwardly of the saddle 56 to pick up the sound vibrations in the strings 15 when vibrated. A tension coil spring 65 is secured at a rear attaching end 65' thereof to a post 66 formed with and projecting from the top surface 46' of the platform 21, and at a forward attaching end 65" to a hole 62' formed near the free end of an associated one of the spring connecting arms 62. As shown, there are two springs 65 connected to a respective one of the spring connecting arms 62 to bias the transverse bridge section 61 of the sound captor 60 against the front abutment wall 27 of the platform 21.
As shown more clearly in Figures 3 and 4, the transducer 32, which is an off the shelf transducer, is formed as an elongated metal rod and it is secured captive on the top surface of the transverse bridge section 61 by a non-metallic body 70, which could be formed in sections, disposed on top of the transducer 32, and an elongated bottom support cap 71 having opposed attaching fingers 72 to engage opposed end cavities 73 of the body 70. A thin damping spacer 74 is secured to the top surface of the transverse bridge section 61 to prevent metal-to-metal contact between the metal transducer and the bridge section 61 which is also metallic. The spacer 74 is constructed of tusk but other suitable material may be used, such as ivory, wood or combinations thereof or any other suitable non-metallic damping material.
The device of the present invention is mounted on the guitar 10 by firstly positioning the sound captor arms 63 between pairs of corresponding strings 15 and the abutting formations 63 disposed against the front face 58 of the saddle 56, as shown in Figure 4. The device or housing is then pulled back to stretch the springs whereby the front abutment wall 27 of the platform, as shown in phantom lines, is space rearwards of the saddle 56. The clamp leg formations 43 are then positioned to rest against the top portion of the rear end of the guitar side wall 16, as shown in Figure 1.
The sound wave vibrations from the strings picked up by the transducer through the sound captor are converted into corresponding electrical signals which are inputted via wire connection 75 into local circuitry mounted on the support platform 49 for local amplification and/or mixing and for retransmission back into the sound box 12 through small speakers or vibrators 55 to mix with the sound vibrations of the strings transmitted into the sound box through the saddle to produce a modified sound coming out of the sound hole 14. In this embodiment the speakers 55 would be resting on the top sound board 13. Alternatively, the sound signals from the local circuitry 22 mounted on the platform 21 could be transmitted back into the sound box by electrical connections 85 from the internal circuitry to the spring connecting arms 62 of the sound captor 60. The output sound signals from the transducer 34 may also be transmitted wirelessly by internal circuitry or conventionally though a plug jack 76 to a remote amplifier or sound processor and speaker system or simply for recording.
As illustrated in Figure 3 a USB and Blue chip component is mounted on the support platform 21 to input programmed sound signals into the device from an iphone which can be attached to the top surface of the housing cover 28, as shown in Figure 1.
The iphone 77 as shown in Figure 1 is attached by a double adhesive tape not shown.
A USB connector cable 78 may also provide the communication link between the iphone 77 and the circuits mounted on the platform.
Referring now to Figure 7 there is illustrated another embodiment of the device of the present invention wherein the tension springs 65 of the Figure 3 embodiment are replaced by long reverberating tension springs 80. The reverberating springs 80 are attached at their rear hook end 81 to lugs 82 formed integral with the rear wall 24 of the platform 21. The front end of the springs have their hook end 83 attached to the spring connecting arms 62 of the sound captor 60. Accordingly, the springs 80 which are in tension with the sound captor 60 create reverberating sound or echos of the natural sound vibrations transmitted into the captor by the plucking of the strings of the instrument to modify the sound vibrations captured by the transducer and also transmitted back into the sound box of the guitar through the saddle and bridge in contact with the top soundboard and into the sound box and thus modifying the sound coming out of the sound hole. The sound signals outputted from the transducer may also be transmitted back into the instrument or mixed with sound tones inputted from an iphone or transmitted to remote electronics equipment for processing, amplifying or recording.
It is within the ambit of the present invention to cover any obvious modifications of the embodiment described herein provided such modification fall within the scope of the appended claims.
