[0032] A phonograph, also known as a gramophone, is a sound playback device, and its sound is stored in the arc-shaped grooves engraved on the record surface by an acoustic method. When music needs to be played, the record is placed on the turntable of the phonograph, and the turntable drives the record to rotate under the stylus. After the audio information collected by the stylus is amplified and processed by the circuit, it is output to a device with a speaker to play music.
[0033] Generally, the stylus of a phonograph can be adjusted in one direction to adjust the contact angle between the stylus and the record. However, when encountering situations such as accidentally touching the stylus or playing records of different specifications, after adjusting the stylus, the fit between the stylus and the record cannot reach the optimal state, thus affecting the sound quality.
[0034] The present utility model provides a cartridge module for a phonograph.
[0035] Please refer to Figure 1 and Figure 2 , in an embodiment of the present utility model, the cartridge module includes a cartridge assembly 100 and an adjustment assembly 200. The cartridge assembly 100 is provided with a stylus 110 for contacting the record; the adjustment assembly 200 includes a first adjustment member 300 and a second adjustment member 400 that are rotatably connected. The second adjustment member 400 is rotatably connected to the cartridge assembly 100. The second adjustment member 400 can rotate relative to the first adjustment member 300 along a first rotation axis, and the cartridge assembly 100 can rotate relative to the second adjustment member 400 along a second rotation axis. The first rotation axis and the second rotation axis are arranged at an angle.
[0036] Generally, the cartridge assembly 100 includes a suspension 130, a tonearm 120, and a stylus 110. The tonearm 120 is installed on the suspension 130, and the stylus 110 is installed on the tonearm 120. When using the phonograph, the suspension 130 is moved to make the stylus 110 contact the record, thereby playing sound.
[0037] The adjustment assembly 200 is connected to the suspension 130 of the cartridge assembly 100 and is used to adjust the contact angle between the stylus 110 and the record. In an embodiment of the present invention, the adjustment assembly 200 includes two adjustment members, namely, a first adjustment member 300 and a second adjustment member 400 that are rotatably connected. The first adjustment member 300 is used to be connected to the body of the record player, and the second adjustment member 400 is rotatably connected to the cartridge assembly 100. In this way, the second adjustment member 400 can rotate relative to the first adjustment member 300 along the first rotation axis, and the cartridge assembly 100 can rotate relative to the second adjustment member 400 along the second rotation axis. That is to say, the second adjustment member 400 and the cartridge assembly 100 can rotate around the first rotation axis, so as to adjust the contact angle between the stylus 110 and the record on the first rotation axis. The cartridge assembly 100 can rotate around the second rotation axis, so as to adjust the contact angle between the stylus 110 and the record on the second rotation axis. The first rotation axis and the second rotation axis are arranged at an angle, that is, the directions where the first rotation axis and the second rotation axis are located are different. In this way, the stylus 110 can adjust the contact angle with the record in two directions, thereby improving the fit between the stylus 110 and the record, and thus improving the sound quality of the record player.
[0038] Of course, in other embodiments, the adjustment assembly 200 may further include three or more adjustment members, and the rotation axes of the plurality of adjustment members are all arranged at an angle. In this way, the stylus 110 can adjust the contact angle with the record in more directions, thereby improving the fit between the stylus 110 and the record.
[0039] The technical solution of the present invention is to provide a cartridge module with a cartridge assembly 100 and an adjustment assembly 200. The cartridge assembly 100 is provided with a stylus 110 that contacts the record. The adjustment assembly 200 includes a first adjustment member 300 and a second adjustment member 400 that are rotatably connected. The second adjustment member 400 is rotatably connected to the cartridge assembly 100. The second adjustment member 400 can rotate relative to the first adjustment along the first rotation axis, and the cartridge assembly 100 can rotate relative to the second adjustment member 400 along the second rotation axis, and the first rotation axis and the second rotation axis are arranged at an angle. In this way, the stylus 110 can adjust the contact angle between it and the record in the directions of the first rotation axis and the second rotation axis, so as to realize the adjustment of the stylus 110 in multiple degrees of freedom, improve the fit between the stylus 110 and the record, thereby improving the sound quality of the record player and the use effect and experience of the record player.
[0040] In an embodiment of the present utility model, the first rotation axis is perpendicular to the second rotation axis. In this way, the adjustment of the stylus 110 in two degrees of freedom is realized, and the adjustment range of the stylus 110 is increased. Of course, in other embodiments, the first rotation axis and the second rotation axis may also be set at an acute angle or an obtuse angle. In this way, the rotation of the stylus 110 in two degrees of freedom can also be realized, and the contact angle between the stylus 110 and the record can be adjusted.
[0041] In an embodiment of the present utility model, the first adjusting member 300 includes a first inner ring 310 and a first outer ring 320. The first inner ring 310 is disposed inside the first outer ring 320, and the first inner ring 310 can rotate relative to the first outer ring 320; the first inner ring 310 is connected to the second adjusting member 400 so that the second adjusting member 400 and the cartridge assembly 100 rotate with the rotation of the first inner ring 310, and the rotation angle of the stylus 110 is adjusted on the first rotation axis.
[0042] Specifically, the first adjusting member 300 includes a first outer ring 320 and a first inner ring 310 that can rotate relative to the first outer ring 320. At the same time, the first inner ring 310 is also connected to the second adjusting member 400, and there is no relative movement between the first inner ring 310 and the second adjusting member 400. In this way, when the first inner ring 310 rotates relative to the first outer ring 320, the second adjusting member 400 can also rotate accordingly, and then drive the cartridge assembly 100 to rotate accordingly, so as to realize the adjustment of the stylus 110 on the first rotation axis. The first rotation axis is also the axis of the first inner ring 310. By setting the structure of the first adjusting member 300 in this way, the overall structure of the first adjusting member 300 is simple, which is beneficial to the simple structure of the record player.
[0043] In an embodiment of the present utility model, the first adjusting member 300 is configured as a first rotary damper. In this way, the use of the first rotary damper enables the stylus 110 to be adjusted to any position on the first rotation axis and fixed at that position, ensuring that the stylus 110 will not be deflected passively, and also saving the setting of the fixing structure, which is beneficial to the simplification of the structure of the cartridge module.
[0044] In one embodiment, a first scale disk is provided on the first rotary damper. The first scale disk is configured as the end face of the first outer ring 320, and scales are provided along its circumferential direction. In this way, when the second adjusting member 400 rotates relative to the first adjusting member 300, it is beneficial to improve the control of the rotation angle accuracy of the first rotary damper. For example, a pointer can be provided at a position where the second adjusting member 400 is close to the first scale disk, and the pointer points to the first scale disk, so that the rotation angle can be accurately known, and the precise adjustment of the stylus 110 can be realized.
[0045] Of course, in other embodiments, the first adjusting member 300 may also be a sleeve structure that can rotate relative to each other. For example, the inner wall of the first outer ring 320 is provided with internal threads, and the outer wall of the first inner ring 310 is provided with external threads. The first inner ring 310 and the first outer ring 320 are threadedly connected through the internal threads and the external threads. In this way, the adjustment and fixation of the stylus 110 on the first rotation axis can also be achieved.
[0046] In an embodiment of the present invention, the second adjusting member 400 includes a second inner ring 410 and a second outer ring 420. The second inner ring 410 is disposed inside the second outer ring 420, and the second inner ring 410 can rotate relative to the second outer ring 420; the second outer ring 420 is connected to the first inner ring 310, and the second inner ring 410 is connected to the cartridge assembly 100, so that the cartridge assembly 100 rotates with the rotation of the second inner ring 410, and the rotation angle of the stylus 110 is adjusted on the second rotation axis.
[0047] Specifically, the second adjusting member 400 includes a second outer ring 420 and a second inner ring 410 that can rotate relative to the second outer ring 420. At the same time, the second inner ring 410 is also connected to the cartridge assembly 100, and there is no relative movement between the second inner ring 410 and the cartridge assembly 100. In one embodiment, the cantilever of the cartridge assembly 100 extends into the second inner ring 410, thereby realizing the connection between the cartridge assembly 100 and the second adjusting member 400. In this way, when the second inner ring 410 rotates relative to the second outer ring 420, the cartridge assembly 100 can also rotate accordingly, thereby realizing the adjustment of the stylus 110 on the second rotation axis. The second rotation axis is also the axis of the second inner ring 410. By setting the structure of the second adjusting member 400 in this way, the overall structure of the second adjusting member 400 is simple, which is beneficial to the simplicity of the structure of the record player.
[0048] In an embodiment of the present invention, the second adjusting member 400 is configured as a second rotary damper. In this way, the use of the second rotary damper enables the stylus 110 to be adjusted to any position on the second rotation axis and fixed at that position, ensuring that the stylus 110 will not be deflected passively, and also saving the setting of the fixing structure, which is beneficial to the simplification of the structure of the cartridge module.
[0049] In one embodiment, a second scale disk is provided on the second rotary damper. The second scale disk is configured as the end face of the second outer ring 420, and scales are provided along the circumferential direction of this end face. In this way, when the cartridge assembly 100 rotates relative to the second adjusting member 400, it is beneficial to improve the control of the accuracy of the rotation angle of the second rotary damper. For example, a pointer can be provided at a position where the cartridge assembly 100 is close to the second scale disk. The pointer points to the second scale disk, and the rotation angle can be accurately known, so as to achieve precise adjustment of the stylus 110.
[0050] Of course, in other embodiments, the second adjusting member 400 may also be a rotatable sleeve structure, which has been introduced above and will not be elaborated here.
[0051] In this way, when it is necessary to adjust the stylus 110 in the direction of the first rotation axis, the cartridge assembly 100 and the second adjusting member 400 are kept relatively stationary, and the second adjusting member 400 is rotated, so that the first inner ring 310 rotates relative to the first outer ring 320, thereby realizing the adjustment of the stylus 110 on the first rotation axis. When it is necessary to adjust the stylus 110 in the direction of the second rotation axis, the first adjusting member 300 and the second adjusting member 400 are kept relatively stationary, and the cartridge assembly 100 is rotated, so that the second inner ring 410 rotates relative to the second outer ring 420, thereby realizing the adjustment of the stylus 110 on the second rotation axis.
[0052] In an embodiment of the present invention, the cartridge module further includes a mounting bracket 500. The mounting bracket 500 is provided with a first adjustment position 510. The first adjusting member 300 further includes a first bracket 330 connected to the first outer ring 320. The first bracket 330 is provided with a second adjustment position 331. The first adjustment position 510 and the second adjustment position 331 are cooperatively connected to make the distance between the stylus 110 and the record adjustable.
[0053] Specifically, the mounting bracket 500 is fixedly connected to the body of the record player. The first adjusting member 300 is connected to the body through the mounting bracket 500. Through the cooperation of the first adjustment position 510 on the mounting bracket 500 and the second adjustment position 331 on the first adjusting member 300, the connection between the first adjusting member 300 and the mounting bracket 500 can be realized, and the connection position between the first adjustment position 510 and the second adjustment position 331 is adjustable. In this way, the length of the cartridge assembly 100 can be adjusted, so that the distance between the stylus 110 and the record can be adjusted, thereby further improving the fit between the stylus 110 and the record and the use effect of the record player.
[0054] In an embodiment of the present invention, the first adjustment position 510 is configured as a first long hole, and the second adjustment position 331 is configured as a second long hole. In this way, a connecting member such as a screw or a bolt passes through the first long hole and the second long hole in sequence, thereby realizing the connection between the mounting bracket 500 and the first adjusting member 300. It can be understood that when connecting the mounting bracket 500 and the first adjusting member 300, as long as the first long hole and the second long hole are partially aligned for the connecting member to pass through. Different alignment positions of the first long hole and the second long hole can adjust the distance between the stylus 110 and the record.
[0055] Of course, in other embodiments, one of the first adjustment position 510 and the second adjustment position 331 can be set as a buckle, and the other can be provided with a plurality of slots arranged at intervals. The buckle can be snap-fitted into one of the slots. By snap-fitting the buckle into different slots, the distance between the stylus 110 and the record can be adjusted.
[0056] In an embodiment of the present utility model, one of the mounting bracket 500 and the first bracket 330 is provided with a limiting hole 520, and the other is provided with a limiting block 332, and the limiting block 332 can move within the limiting hole 520.
[0057] It can be understood that sound blank areas are often provided in records, that is, sound blank areas are often provided at the beginning of a section of audio. When using a record player to play sound, the stylus 110 generally first contacts the sound blank area of the record. After a period of time, such as 1-5 seconds, sound starts to be broadcast. In order to control the stylus 110 to contact the sound blank area of the record and control the contact time between the stylus 110 and the sound blank area of the record, the distance between the stylus 110 and the record needs to be controlled.
[0058] Taking the case where the mounting bracket 500 is provided with the limiting hole 520 and the first bracket 330 is provided with the limiting block 332 as an example. The size of the limiting block 332 is smaller than the size of the limiting hole 520, so that the limiting block 332 can move within the limiting hole 520 to adjust the connection position between the mounting bracket 500 and the first bracket 330. The aperture size of the limiting hole 520 can limit the duration of the contact time between the stylus 110 and the sound blank area of the record. Thus, compared with the method of roughly positioning the distance between the stylus 110 and the record by the cooperation of the first adjustment position 510 and the second adjustment position 331, in this embodiment, by adjusting the position of the limiting block 332 in the limiting hole 520, the distance between the stylus 110 and the record is precisely positioned.
[0059] The present utility model also proposes a record player, which includes a cartridge module. The specific structure of the cartridge module refers to the above embodiments. Since this record player adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, and will not be elaborated one by one here.
[0060] The above are only exemplary embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
