Description

Technical Field

[0001] This utility model relates to the field of audio equipment technology, and more specifically, to a rotary tuning speaker. Background Technology

[0002] A speaker is a device that converts audio signals into sound. In simpler terms, it refers to a speaker enclosure or subwoofer enclosure that has a built-in power amplifier that amplifies the audio signal before the speaker itself reproduces the sound, making it louder.

[0003] The speaker is the terminal of the entire audio system. Its function is to convert audio electrical energy into corresponding sound energy and radiate it into space. It is an extremely important component of the audio system, responsible for converting electrical signals into sound signals for direct listening by the human ear.

[0004] Patent document CN222602521U discloses a portable speaker, comprising: a first half-shell, a second half-shell, and a control board disposed on the first half-shell and the second half-shell. The control board has a first fixing structure and a second fixing structure. The inner shell wall of the first half-shell has a first limiting structure and a second limiting structure, forming a first limiting space between the first limiting structure and the second limiting structure. The inner shell wall of the second half-shell has a third limiting structure, which has a second limiting space. The first fixing structure is inserted into the first limiting space and the second fixing structure is inserted into the second limiting space, thereby fixing the control board between the first half-shell and the second half-shell. The fixing method of the control board is simple to operate, has high assembly efficiency, and low manufacturing cost. In addition, the above design can maximize the internal cavity volume of the portable speaker to meet acoustic requirements, and uses less shell material, making assembly convenient and saving costs. At the same time, the portable speaker has a curved surface and is equipped with ribs and buckles, which improves overall reliability.

[0005] Traditional speaker volume is adjusted via touch buttons, which require multiple presses to adjust the volume, making volume control inconvenient.

[0006] Therefore, it is necessary to propose a rotary tuning speaker to solve the problems existing in the prior art. Utility Model Content

[0033] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

A sensor control component is provided between the speaker housing 1 and the base 2 to adjust the volume according to the rotation angle between the speaker housing 1 and the base 2.

[0035] Furthermore, the sensing control component includes an annular component 3, which is disposed on the upper surface of the base 2. Multiple baffles 4 are arranged in an array along the circumferential direction on the inner wall of the annular component 3. A bidirectional detection switch 5 is fixedly disposed inside the speaker housing 1. The bidirectional detection switch 5 is located inside the annular component 3, and the baffles 4 are in contact with the knob button of the bidirectional detection switch 5.

[0036] Furthermore, the speaker housing 1 includes an upper housing 101 and a lower housing 102, which are detachably connected. A mounting bracket 8 is provided inside the upper housing 101, and a bidirectional detection switch 5 is fixedly mounted on the bottom surface of the mounting bracket 8.

[0037] Furthermore, a bearing outer ring 9 is provided on the bottom surface of the mounting bracket 8, and bearing balls 11 are provided in the groove 10 of the bearing outer ring 9;

[0038] The inner ring 12 of the bearing is fixedly installed on the upper end surface of the annular component 3, and the inner ring 12 of the bearing is connected to the outer ring 9 of the bearing.

[0039] Furthermore, multiple wedge-shaped blocks 13 are arranged in an array along the circumferential direction on the lower part of the outer circumferential surface of the bearing outer ring 9;

[0040] At least three hooks 14 are fixedly provided along the circumferential direction on the upper end surface of the annular component 3 at positions corresponding to the wedge-shaped block 13, and the hooks 14 engage with the wedge-shaped block 13.

[0041] Furthermore, the inner wall of the annular component 3 has the same radial dimension as the inner wall of the bearing inner ring 12, and the baffle 4 extends upward into the interior of the bearing inner ring 12 and is fixedly connected to the bearing inner ring 12.

[0042] Furthermore, the annular component 3 includes an outer ring 301 and an inner ring 302. A connecting arm 303 is provided between the outer ring 301 and the inner ring 302. At least three connecting arms 303 are provided along the circumferential direction of the annular component 3. One end of the connecting arm 303 is fixedly connected to the inner wall of the outer ring 301, and the other end of the connecting arm 303 is fixedly connected to the outer circumference of the inner ring 302.

[0043] The outer ring 301 is detachably connected to the base 2.

[0044] Furthermore, the annular component 3 is connected to the base 2 using screws.

[0045] Furthermore, the base 2, the annular component 3, and the speaker housing 1 are coaxially arranged.

[0046] Furthermore, an anti-slip pad 15 is fixedly installed on the bottom surface of the base 2.

[0047] The working principle of the above technical solution:

[0048] Speaker volume control is an essential part of the entire speaker system. Generally, speaker buttons on the market are implemented in two ways:

[0049] One method uses a tactile switch. Due to structural limitations, the tactile switch button is small and not very noticeable. Adjusting the volume requires pressing it multiple times, which can sometimes make volume adjustment inconvenient.

[0050] One approach is to use a hollow encoder switch. However, since the hollow encoder switch is a standard component, the overall structure is greatly constrained by this component, and the cost of using a hollow encoder switch is relatively high.

[0051] The rotary tuning speaker of this utility model includes a speaker housing 1 and a base 2. The speaker housing 1 and the base 2 are rotatably connected. The speaker housing 1 includes an upper housing 101 and a lower housing 102. A mounting bracket 8 is provided inside the upper housing 101. A bidirectional detection switch 5 is installed on the bottom surface of the mounting bracket 8. The bidirectional detection switch 5 can be installed on the mounting bracket 8 by screws. An annular component 3 is provided on the upper end surface of the base 2. Multiple baffles 4 are arranged in an array along the circumferential direction on the inner wall of the annular component 3. A bearing inner ring 12 is fixedly provided on the upper end surface of the annular component 3. The radial dimension of the inner wall of the annular component 3 is the same as that of the inner wall of the bearing inner ring 12. The baffles 4 extend upward into the inner ring 12 and are fixedly connected to the bearing inner ring 12. The upper edge of the baffle 4 is in the same plane as the upper edge of the bearing inner ring 12. A bearing outer ring 9 is provided on the bottom surface of the mounting bracket 8. Bearing balls 11 are provided in the groove 10 of the bearing outer ring 9. During installation, the bearing balls 11 are first coated with grease and then placed. The inner ring 12 of the bearing is inserted into the outer ring 9 of the bearing, which can be configured as a spherical groove. The inner ring 12 and the outer ring 9 of the bearing together form a separable bearing, facilitating speaker assembly. When the inner ring 12 is inserted into the outer ring 9, the wedge-shaped locking block 13 presses against the hook 14, causing the hook 14 to tilt outward. When the inner ring 12 and the outer ring 9 are fully engaged, the wedge-shaped locking block 13 enters the hook 14, and the hook 14, under elastic action... The downward rebound engages the wedge-shaped locking block 13, connecting the annular component 3 to the mounting bracket 8. Multiple hooks 14 are arranged in a circumferential array, with the hooks of the multiple hooks 14 facing inward to form an intermittent annular structure. The multiple wedge-shaped locking blocks 13 arranged in the annular structure formed by the multiple hooks 14 can slide within the annular structure formed by the multiple hooks 14. The spacing between the wedge-shaped locking blocks 13 is smaller than the width of the hooks 14, preventing the wedge-shaped locking blocks 13 from falling off the hooks 14, thereby allowing the mounting bracket 8 and the annular component 3 to rotate.

[0052] The annular component 3 includes an outer ring 301 and an inner ring 302. A connecting arm 303 is provided between the outer ring 301 and the inner ring 302. At least three connecting arms 303 are provided along the circumference of the annular component 3. One end of the connecting arm 303 is fixedly connected to the inner wall of the outer ring 301, and the other end of the connecting arm 303 is fixedly connected to the outer circumference of the inner ring 302. The connecting arm 303 can be made of an elastic material, such as an elastic polymer, which can play a buffering role. When adjusting the volume, if a large force is applied, it can buffer the impact between the speaker housing 1 and the base, and it can also play a buffering role when the speaker housing 1 is impacted.

[0053] The outer ring 301 is detachably connected to the base 2, and screw connection can be selected. The base 2, the ring component 3 and the speaker housing 1 are coaxially arranged to increase the stability of the speaker housing 1 when it rotates.

[0054] An anti-slip pad 15 is fixedly installed on the bottom surface of the base 2. The anti-slip pad 15 can be made into a ring shape and can be made of silicone material.

[0055] The speaker, circuit board, and other electrical components of the speaker are all located above the mounting bracket 8 inside the upper housing 101. The upper surface of the upper housing has sound outlet holes (not shown in the figure) according to the speaker's mounting position. Multiple sound outlet holes are provided; the specific arrangement is existing technology and will not be described further here. During installation, first connect the upper housing 101 with the installed electrical components to the mounting bracket 8 using screws. Then, apply grease to the bearing balls 11 and place them in the groove 10. Align the inner bearing ring 12 with the outer bearing ring 9 on the annular component 3 and install the annular component 3 onto the mounting bracket 8. Then rotate the annular component 3 to check if the rotation is smooth. Next, connect the base 2 to the annular component 3. Then, align the lower housing 102 upwards with the upper housing 101 from below the base 2 and connect it with screws. The lower part of the lower housing 102 has a hole for the base 2 to extend to the outside of the lower housing 102. The diameter of the hole is larger than the diameter of the base 2. The upper end face of the base 2 has a frustum, the diameter of which is larger than the diameter of the hole.

[0056] The working principle of a bidirectional detection switch, such as Figure 7As shown, when the speaker housing 1 is rotated, the baffle 4 moves the knob of the bidirectional detection switch 5. The knob of the bidirectional detection switch 5 has two directions: positive and negative. A positive direction triggers the switch once, generating a voltage through R68 at point A. A negative direction triggers the switch once, generating a voltage through R67 at point B. The positive and negative voltages are transmitted to the CPU pins via the SW_ADD and SW_DEC signal networks, respectively. The CPU collects and processes these pin signals. The CPU calculates the key value for each direction based on the knob's direction. Specifically, the CPU detects the voltage; a high level in the positive direction of the knob is considered a valid key press. The detected key value is reported, including the direction and angle. The angle represents the number of key presses. This direction and angle information corresponds to the specific volume adjustment range in the CPU. The volume is increased by mapping the output amplitude of the main control chip's audio DAC through code. Reverse rotation of the speaker housing 1 decreases the volume using the same principle. The CPU model that can be selected includes MT8516.

[0057] This invention utilizes the overall rotation of the speaker box to replace the traditional buttons and hollow encoder switches. It has a simple structure, low cost, and is equivalent to increasing the size of the buttons, making it more convenient for users to operate.

[0058] The beneficial effects of the above technical solution are as follows:

[0059] The rotary tuning speaker of this invention allows for volume adjustment simply by rotating the speaker shell. A two-way detection switch detects the rotation direction and angle between the speaker shell and the base, thus adjusting the speaker volume quickly and conveniently.
