[0025] Example Please refer to the following: Figure 1 and Figure 2 This embodiment provides a CD speaker for use in a CD player. The CD speaker includes a housing 100, a main speaker 200, a secondary speaker 300, and a duct 400.
[0026] The outer casing 100 has a receiving cavity 101. A cavity 102 is disposed inside the receiving cavity 101, and the cavity 102 and the outer casing 100 together form a bass cavity 103.
[0027] The main speakers 200 are respectively disposed on both sides of the housing 100, and the main speakers 200 are exposed in the receiving cavity 101. The main speakers 200 are used to play mid-to-high frequency sounds.
[0028] The secondary speaker 300 is disposed in the housing 100 and exposed in the bass cavity 103. The secondary speaker 300 is used to play low-frequency sounds.
[0029] The air duct 400 is installed on the outer casing 100, and the air duct 400 connects the bass chamber 103 and the outside of the outer casing 100 respectively.
[0030] Mid-to-high frequency sounds include both mid-frequency and high-frequency sounds, typically corresponding to frequencies above 200Hz. Low-frequency sounds typically correspond to frequencies between 20-200Hz.
[0031] In the aforementioned CD speaker, the main speaker 200 plays mid-to-high frequency sounds. Due to the characteristics of sound, the main speaker 200 does not require a separate cavity 102; instead, it is directly exposed within the housing cavity 101 inside the outer casing 100, yet still delivers excellent performance. Simultaneously, the main speakers 200 are positioned on both sides of the outer casing 100, enhancing the stereo effect of the CD speaker. Furthermore, the secondary speaker 300 plays low-frequency sounds, and in conjunction with the independent bass cavity 103 and the duct 400, significantly improves the bass response of the CD speaker. Therefore, the aforementioned CD speaker delivers better sound quality and better meets user needs.
[0032] In some embodiments, the main speaker 200 is a tweeter and the secondary speaker 300 is a woofer.
[0033] It should be noted that while tweeters can play other frequency bands besides high-frequency sounds, their performance is poor when playing low-frequency sounds. Therefore, in this embodiment, a tweeter is used as the main speaker 200 to play sounds other than low-frequency sounds, while a woofer is used as the secondary speaker 300 to play low-frequency sounds.
[0034] Please see Figure 3 In some embodiments, the outer casing 100 includes a bottom shell 110, a front cover support 120, and a front cover 130. The bottom shell 110, the front cover support 120, and the front cover 130 are stacked sequentially along the thickness direction of the CD speaker, that is, in the vertical direction, and the bottom shell 110 and the front cover support 120 together form a receiving cavity 101. The front cover 130 covers the front cover support 120, ensuring the integrity of the CD speaker's appearance and making the CD speaker more aesthetically pleasing.
[0035] Please refer to the following: Figure 3 and Figure 4 In some embodiments, the housing 100 has a first sidewall 111 on the front and two second sidewalls 112 on the sides, the two second sidewalls 112 being connected to the two ends of the first sidewall 111 respectively.
[0036] Understandably, the front of the housing 100 refers to the surface of the housing 100 facing the user horizontally during normal use of the CD speaker. In this embodiment, the first sidewall 111 and the second sidewall 112 are both part of the bottom shell 110.
[0037] The second sidewall 112 is provided with a first mesh 113. The main speaker 200 is disposed on the second sidewall 112, and the main speaker 200 corresponds to the first mesh 113.
[0038] In use, the sound emitted by the main speaker 200 is transmitted to the outside of the housing 100 through the first mesh 113. By placing the main speaker 200 on the second side wall 112, the main speaker 200 can emit sound from the side, which can better improve the stereo effect of the CD speaker.
[0039] Furthermore, in some embodiments, a retaining member 114 is provided on one side of the second sidewall 112 exposed in the receiving cavity 101, and the main speaker 200 is secured to the retaining member 114.
[0040] The main speaker 200 can be easily fixed to the second side wall 112 by inserting it into the retainer 114.
[0041] Specifically, a slot 115 is formed between the retaining member 114 and the second sidewall 112. The slot 115 is aligned with the first mesh 113 in a direction perpendicular to the second sidewall 112, and the top of the slot 115 is open.
[0042] The main speaker 200 has an annular first protrusion 210 at one end near the second side wall 112. The first protrusion 210 is inserted into the slot 115 from top to bottom, so that the main speaker 200 is stably connected to the second side wall 112 and the main speaker 200 is aligned with the first mesh 113 in a direction perpendicular to the second side wall 112.
[0043] In some embodiments, the housing 100 has a bottom plate 116 located on the bottom surface, and a second mesh 117 is provided on the bottom plate 116. A secondary speaker 300 is disposed on the bottom plate 116, and the secondary speaker 300 corresponds to the second mesh 117.
[0044] Accordingly, the cavity 102 and the base plate 116 together form the bass cavity 103.
[0045] In use, the sound emitted by the secondary speaker 300 is transmitted to the outside of the housing 100 through the second mesh 117. Since the main speaker 200 is located on the second side wall 112 and the secondary speaker 300 is located on the bottom plate 116, there is no speaker on the first side wall 111 on the front of the housing 100, so there is no need to open a speaker hole, making the CD speaker more aesthetically pleasing.
[0046] In this embodiment, the base plate 116 is also part of the bottom shell 110.
[0047] Furthermore, in some embodiments, a positioning member 118 protrudes from one side of the base plate 116 exposed to the bass cavity 103, and the secondary speaker 300 is embedded in the positioning member 118.
[0048] Specifically, the positioning element 118 is arranged in a ring and surrounds the second mesh 117.
[0049] By embedding the secondary speaker 300 into the positioning member 118 from top to bottom, the secondary speaker 300 can be precisely aligned so that the secondary speaker 300 is aligned vertically with the second mesh 117.
[0050] Furthermore, in some embodiments, a fixing member 119 is provided on the side of the base plate 116 exposed above the bass cavity 103. The fixing member 119 is connected to the base plate 116 and abuts against the secondary speaker 300 in the direction toward the base plate 116.
[0051] In use, the fixing member 119 holds the secondary speaker 300, which can prevent the secondary speaker 300 from coming out of the positioning member 118 upwards, so that the secondary speaker 300 is stably connected to the base plate 116.
[0052] Specifically, the secondary speaker 300 has an annular second protrusion 310 at one end near the base plate 116. After the secondary speaker 300 is inserted into the positioning member 118, the fixing member 119 is installed and fixed on the base plate 116 from top to bottom, and the outer edge of the fixing member 119 abuts against the second protrusion 310.
[0053] Optionally, the upright plate has an integrally formed column, and the fastener 119 is sleeved on the column and interference fits with the column, thereby being installed and fixed on the base plate 116.
[0054] Please see Figure 5 In some embodiments, the CD speaker further includes a first seal 104. The first seal 104 is located between the cavity 102 and the inner wall of the outer shell 100, and the cavity 102 abuts against the inner wall of the outer shell 100 through the first seal 104.
[0055] In use, the first seal 104 can enhance the sealing of the connection between the cavity 102 and the outer shell 100, making the bass cavity 103 more airtight and preventing the bass cavity 103 from communicating with the receiving cavity 101. Instead, it can only communicate with the outside of the outer shell 100 through the air duct 400.
[0056] Specifically, the first sealing element 104 is an annular sealing ring, and the first sealing element 104 is located between the cavity 102 and the bottom plate 116.
[0057] In some embodiments, the CD speaker further includes a second seal 105. The second seal 105 is located between the duct 400 and the inner wall of the housing 100, and the duct 400 abuts against the inner wall of the housing 100 through the second seal 105.
[0058] In use, the second seal 105 enhances the sealing at the connection between the duct 400 and the housing 100, so that the duct 400 and the housing 100 together form a long strip-shaped air duct. One end of the air duct is connected to the bass chamber 103, and the other end is connected to the outside of the housing 100 through a through hole opened on the housing 100.
[0059] Specifically, the second seal 105 is a sealing ring adapted to the edge shape of the duct 400, and the second seal 105 is located between the duct 400 and the base plate 116.
[0060] In summary, in the aforementioned CD speaker, the main speaker 200 plays mid-to-high frequency sounds. Due to the characteristics of sound, the main speaker 200 does not require a separate cavity 102; instead, it is directly exposed within the housing cavity 101 inside the outer casing 100, yet still performs well. This significantly saves space and allows for a more compact CD speaker design. Simultaneously, the main speakers 200 are positioned on both sides of the outer casing 100, enhancing the stereo effect of the CD speaker. Furthermore, the secondary speaker 300 plays low-frequency sounds. Combined with a separate bass chamber 103 and a duct 400, this significantly improves the bass response of the CD speaker, and the vibrations emitted by the secondary speaker 300 are also reduced, resulting in less vibration within the CD speaker itself. Therefore, the aforementioned CD speaker delivers better sound quality and better meets user needs.
[0061] This embodiment also provides a CD player, including the CD speaker described above.
[0062] Please see Figure 3 In some embodiments, the CD player further includes a battery 500, a PCB board 600, and a mechanism 700. The top of the mechanism 700 protrudes from the center of the cover support 120, providing space for a CD disc 10. Correspondingly, the cover 130 is annularly arranged to avoid obstructing the CD disc 10.
[0063] The working process and principle of the main speaker 200, secondary speaker 300, battery 500, PCB board 600 and mechanism 700 in playing CD disc 10 are conventional technologies and will not be described in detail in this embodiment.
[0064] In some embodiments, the CD player further includes a display screen 800 and buttons 900, and both the display screen 800 and buttons 900 are disposed on the first side wall 111, that is, disposed on the front of the entire CD player.
[0065] The buttons 900 allow users to control the CD player, such as play, pause, fast forward, and rewind, while the display screen 800 shows the corresponding status and information about the CD disc 10.
[0066] In all examples shown and described herein, any specific values should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.
[0067] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0068] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
