Description

Technical Field

[0001] This application relates to a loudspeaker structure, and more particularly to a loudspeaker structure with adjustable rotation. Background Technology

[0002] When using audio equipment, while pursuing cost-effectiveness, the sound quality of the equipment is also required to be extremely refined, striving to achieve the best effect when listening to music. As the soul of audio equipment, the configuration of speakers should naturally be personalized. For example, due to the limited space and the placement of other furniture, audio equipment for home entertainment is usually the last thing to be set up, and therefore the most restrictions are imposed on its placement. However, as the main body of audio equipment, the orientation of the speaker's sound-emitting part and the user's position will affect the experience. For example, the head-related transfer function (HRTF) involves the directionality between the speaker and the user's head and ears. If the audio equipment is not placed in the optimal position, it will greatly affect the user experience, thus failing to bring out the performance of the product and seriously damaging the reputation.

[0003] Because tweeters are more directional than woofers, the difference in the direction of their sound radiation is noticeable to users. This is especially true given the limited space available, where audio equipment is often placed in various ways, such as hanging on a wall, placing in a corner, along a wall, standing upright, lying horizontally, or tilting. The speakers radiate different directions depending on their placement, preventing listeners from achieving the optimal high-frequency listening area. Furthermore, after positioning the audio equipment, users need to return to their listening position at a certain distance to confirm if it is correctly placed. If not, they must repeatedly go back and forth, which is extremely time-consuming and laborious. Not to mention that some speaker equipment is too heavy or bulky to be adjusted to the optimal listening angle.

[0004] Therefore, those skilled in the art urgently need to develop a loudspeaker that can quickly and easily adjust the direction of sound emission and is not limited by the position of the audio equipment, so as to provide users with the best listening experience. Utility Model Content

[0005] In view of the above-mentioned problems in the related technologies, this application proposes a speaker structure that allows users to remotely adjust the sound direction of the speaker from their existing position, so as to personalize and finely adjust the listening quality.

[0006] The technical solution of this application is implemented as follows: According to one aspect of this application, a loudspeaker structure is provided, comprising a housing having a cavity inside and an opening communicating with the cavity; a waveguide disposed within the opening and rotatable relative to the housing; a transducer located within the cavity and connected to the waveguide; a transmission mechanism disposed in the housing and providing a driving force for the rotation of the waveguide; and a pivoting mechanism connected between the transmission mechanism and the waveguide, the pivoting mechanism being driven by the transmission mechanism and providing support for the rotation of the waveguide relative to the housing.

[0007] According to an embodiment of this application, the pivoting mechanism includes at least one pivot member disposed on the waveguide, and a fixing member disposed on the transmission mechanism for fixing the at least one pivot member.

[0008] According to an embodiment of this application, the transmission mechanism includes a motor and a transmission gear engaged with the motor.

[0009] According to an embodiment of this application, it further includes an airtight ring disposed on the outer peripheral surface of the waveguide and located between the waveguide and the inner wall of the opening.

[0010] According to an embodiment of this application, the outer peripheral surface of the waveguide has an airtight groove corresponding to the airtight ring, and the airtight ring is at least partially housed within the airtight groove.

[0011] According to an embodiment of this application, the airtight ring has at least one fixed ring, which is correspondingly sleeved on at least one pivot member on the waveguide.

[0012] According to an embodiment of this application, the outer periphery of the waveguide is spherical, and the inner wall of the opening has an arc to correspond to the spherical outer periphery of the waveguide.

[0013] According to an embodiment of this application, the outer periphery of the waveguide is spherical, and the maximum radius of the waveguide is approximately the same as the maximum radius of the opening, or the maximum radius of the waveguide is smaller than the maximum radius of the opening.

[0014] According to an embodiment of this application, the waveguide has corresponding holes and the transducer is shaped to engage the transducer onto the waveguide.

[0015] According to an embodiment of this application, a controller device is further included, the controller device including a drive module disposed on the transmission mechanism to control the driving force provided by the transmission mechanism, and a control module to control the drive module.

[0016] The speaker structure of this application provides convenient adjustment of the speaker's directional sound, especially the highly directional high-frequency driver. Users can adjust the transducer's rotation angle through the transmission mechanism and controller without leaving their original listening position to achieve the best listening effect. The controller may include a light sensor or a heat sensor to sense the user's current position and automatically adjust the transducer's rotation angle, allowing the user to continue to obtain the best acoustic experience while moving.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0020] like Figures 1 to 5 As shown, the loudspeaker structure according to an embodiment of this application includes a housing 10, a waveguide 20, a transducer 30, a pivoting mechanism 40, and a transmission mechanism 50.

[0021] The housing 10 has a cavity 11 and an opening 12 communicating with the cavity 11. The waveguide 20 has an annular structure and a spherical outer peripheral surface. The waveguide 20 is movably disposed in the opening 12 and can rotate relative to the housing 10. The waveguide 20 has a connection hole 21 with a preset shape corresponding to the size and shape of the transducer 30. The transducer 30 can be various types of units, such as high-frequency units, low-frequency units, coaxial units, or global units. This application uses a high-frequency unit as an example, but it is not limited thereto. The transducer 30 is housed in the cavity 11 and connected to the waveguide 20 so that it rotates with the waveguide 20.

[0022] The pivoting mechanism 40 is connected between the transmission mechanism 50 and the waveguide 20 to provide support and fixation for the rotation of the waveguide 20 relative to the housing 10. The pivoting mechanism 40 includes at least one pivot member 41 disposed on the waveguide 20 and a fixing member 42 disposed on the transmission mechanism 50. The pivot member 41 is axially fixedly extended from the outer peripheral surface of the waveguide 20 and has a predetermined shape to correspond to the fixing member 42 fixed on the transmission mechanism 40, so that the waveguide 20 is driven by the transmission mechanism 50 to generate a rotational movement relative to the housing 10.

[0023] The transmission mechanism 50 is disposed on the housing 10 and is connected to the waveguide 20 through the engagement of the fixing member 42 and the pivot member 41 of the pivot mechanism 40. The transmission mechanism 50 may be a motor 51 and a transmission gear 52 meshing with the motor 51, or a stepper motor and a transmission belt (not shown) engaged with the stepper motor, or a solenoid valve and a lever (not shown) assembled with the solenoid valve. In this embodiment, the transmission mechanism 50 is a motor 51 and a transmission gear set cooperating with the motor 51. In this embodiment, the fixing member 42 of the pivot mechanism 40 is a fixing hole provided on the transmission gear set. The fixing hole has a predetermined shape and engages with the pivot member 41.

[0024] With the above structure, the transducer 30 of the embodiment of this application can be rotated relative to the housing 10 by the transmission mechanism 50. The transmission mechanism 50 can remotely control the rotation of the transducer 30 through a remote control, mobile phone application software, or remote device, so that the user can adjust the direction of sound without leaving the position.

[0025] To improve the sealing effect of the housing 10 and achieve a better resonance effect, this embodiment further includes an airtight ring 60. The airtight ring 60 is disposed on the outer peripheral surface of the waveguide 20 and located between the waveguide 20 and the inner wall of the opening 12. In order to make the connection between the airtight ring 60 and the waveguide 20 tighter, an airtight groove 22 is provided on the outer peripheral surface of the waveguide 20 to at least partially accommodate the airtight ring 60. The airtight ring 60 is provided with at least one fixing ring 61, which is correspondingly sleeved on at least one pivot member 41 on the waveguide 20 to enhance the bonding effect between the airtight component 60 and the waveguide 20.

[0026] like Figure 6-7 As shown, the housing 10 includes a first housing 13 and a second housing 14, which are connected to each other to form a chamber 11. The joint between the first housing 13 and the second housing 14 forms an opening 12. The inner wall of the opening 12 has an arc to correspond to the spherical outer circumference of the waveguide. In order to achieve a better airtight effect, the maximum radius B of the spherical outer circumference of the waveguide 20 is approximately the same as the maximum radius A of the opening 12, or the maximum radius B of the spherical outer circumference of the waveguide 20 is slightly smaller than the maximum radius A of the opening 12, so that the airtight component 60 is located between the waveguide 20 and the opening 12 to prevent air from entering the chamber 11.

[0027] The angle C between the spherical central axis extension direction of waveguide 20 and the maximum diameter extension direction of opening 12 can be 60 degrees to 90 degrees. In this embodiment, the angle C between the spherical central axis extension direction of waveguide 20 and the maximum diameter extension direction of opening 12 can be 45 degrees to 90 degrees.

[0028] This application further includes a controller device (not shown), which includes a drive module disposed on the transmission mechanism 50 to control the driving force provided by the transmission mechanism 50, and a control module to control the drive module. The controller device can remotely control the drive module through the control module with remote control, or sense the user's current position and automatically adjust the rotation angle of the transducer 30 through a light sensor or a heat sensor.

[0029] The speaker structure of this application provides convenient adjustment of the speaker's directional sound, especially the highly directional high-frequency driver. Users can adjust the transducer's rotation angle through the transmission mechanism and controller without leaving their original listening position to achieve the best listening effect. The controller may include a light sensor or a heat sensor to sense the user's current position and automatically adjust the transducer's rotation angle, allowing the user to continue to obtain the best acoustic experience while moving.

[0030] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
