Description

Technical Field

[0001] This utility model relates to the field of headphone technology, and in particular to a tweeter module, a tweeter device, and a headset. Background Technology

[0002] Most headphones on the market today use a single-speaker design, meaning that only one main speaker is located in each of the left and right earcups for audio output. This design performs reasonably well in the bass and midrange, but often falls short in the high-frequency range, especially in detail and high-frequency response. The sound projection is relatively diffuse, the volume is low, the propagation distance is short, and the sound production efficiency is relatively low. It may require a larger amplitude to achieve the same sound pressure level, making it difficult to meet users' pursuit of a high-quality music experience. Utility Model Content

[0003] This invention addresses the shortcomings of ordinary headphones in terms of high-frequency detail and response, relatively dispersed sound projection, low volume, short propagation distance, and relatively low sound efficiency, which make it difficult to meet users' pursuit of a high-quality music experience. It provides a tweeter module, a speaker device, and headphones.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A tweeter module includes a horn assembly, the horn assembly including a horn body and a horn bracket, the horn body having a tweeter inside, one end of the horn body having a sound amplification cavity, the horn bracket being installed inside the sound amplification cavity, the outer surface of the horn bracket and the inner surface of the horn body forming a playback channel, the playback channel being connected to the tweeter.

[0006] As described above, in the tweeter module, the end of the horn body away from the amplification cavity is provided with a tweeter mounting slot, which is connected to the playback channel and is used to install the tweeter.

[0007] As described above, the tweeter module has a positioning hole inside the amplification cavity and a support column on the horn bracket. The support column cooperates with the positioning hole to fix the horn bracket inside the amplification cavity.

[0008] As described above, the horn body of the tweeter module also includes a mounting base, and one end of the amplification cavity is fixed to the mounting base.

[0009] As described above, the tweeter module has a small opening and a large opening in the sound amplification cavity. The small opening is close to the tweeter, and the large opening is far from the tweeter. The inner diameter of the sound amplification cavity gradually increases from the small opening to the large opening.

[0010] A loudspeaker device includes a tweeter module and a loudspeaker housing for mounting the tweeter module, wherein a main loudspeaker is disposed within the loudspeaker housing.

[0011] As described above, the horn device includes a horn face cover, a horn rear cavity cover, and a horn rear shell, and the horn assembly, horn face cover, main horn, horn rear cavity cover, and horn rear shell are distributed sequentially along the axial direction.

[0012] The speaker device described above includes a microphone assembly, which includes a feedback microphone, a feedforward microphone, and a talk microphone. The feedback microphone is disposed on the speaker front cover, and the feedforward microphone and the talk microphone are disposed on the speaker rear cavity cover.

[0013] The speaker device described above includes a tuning mesh assembly, which includes a front cavity tuning mesh disposed on the speaker face cover, a rear cavity tuning mesh disposed on the speaker rear cavity cover, a feedforward tuning mesh disposed on the speaker rear shell cover, and a microphone tuning mesh disposed on the speaker rear shell cover.

[0014] A pair of headphones includes a speaker assembly and an ear shell assembly for mounting the speaker module.

[0015] Compared with existing technologies, the beneficial effects of this technical solution are as follows:

[0016] 1. With the structure of this utility model, the tweeter in the horn assembly is set inside the horn body. When the tweeter plays, the sound is transmitted through the playback channel. The design of the horn can concentrate the sound projection direction, making the volume larger and the sound travel further. It can improve the volume and projection distance, improve the sound generation efficiency, control the sound diffusion angle, and eliminate the need to use more expensive horns, thus reducing costs.

[0017] 2. Due to the dual-speaker layout design, a tweeter is added on top of the main speaker, which significantly improves the headphone's detail performance and high-frequency response in the high-frequency range, satisfying users' pursuit of a high-quality music experience.

[0018] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0019] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0022] Figure 3 This is a cross-sectional view of the horn device of this utility model;

[0023] Figure 4 This is a structural schematic diagram of the tweeter module of this utility model;

[0024] Figure 5 This is a cross-sectional view of the tweeter module of this utility model; Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: Figure 1 As shown, this embodiment discloses a headset, including as follows: Figures 2 to 3 The speaker device and the ear shell assembly 6 for mounting the speaker device are shown. The ear shell assembly 6 includes a left ear shell assembly 61 and a right ear shell assembly 62, and a headband 7 is connected between the left ear shell assembly 61 and the right ear shell assembly 62.

[0027] like Figures 2 to 3 A horn device is shown, comprising, as Figures 4 to 5 The diagram shows a tweeter module and a speaker housing 2 for mounting the horn assembly 1, with a main speaker 3 housed within the speaker housing 2. The horn assembly 1, integrated with the main speaker 3, effectively compensates for the main speaker 3's shortcomings in high frequencies. Due to the dual-speaker layout design, with a tweeter integrated with the main speaker, the headphones significantly improve detail and high-frequency response in the high-frequency range, satisfying users' pursuit of a high-quality music experience.

[0028] As a specific implementation and not a limitation, in order to make the headphone layout more compact, the speaker housing 2 includes a speaker face cover 21, a speaker rear cavity cover 22, and a speaker rear shell 23. The horn assembly 1, speaker face cover 21, main speaker 3, speaker rear cavity cover 22, and speaker rear shell 23 are distributed sequentially along the axial direction. The sequential axial distribution of the speaker face cover 21, speaker rear cavity cover 22, and speaker rear shell 23 can greatly reduce the radial layout, making the headphone more compact and its size controllable.

[0029] Furthermore, a microphone assembly 4 is included, comprising a feedback microphone 41, a feedforward microphone 42, and a call microphone 43. The feedback microphone 41 is disposed on the speaker cover 21, while the feedforward microphone 42 and the call microphone 43 are disposed on the speaker rear cavity cover 22. The feedback microphone 41 is primarily used for active noise cancellation, collecting noise signals inside the headphones by placing a feedback microphone 41 inside the headphones. This microphone captures sounds heard by the user's ears, including ambient noise and sounds generated by the headphones themselves. The noise cancellation system then generates a signal of the same magnitude but opposite phase to these sounds to cancel out the noise inside the headphones. The feedforward microphone 42 is used to collect ambient noise signals. The feedforward microphone 42 is sensitive to mid-frequency noise and processes noise faster, but it struggles to handle "slipped noise." While the feedback microphone 41 processes noise more slowly, it handles low-frequency noise better and has stronger resistance to interference such as wind noise.

[0030] As a specific implementation and not a limitation, to enable the headphones to adjust sound quality and reduce noise, a tuning mesh assembly 5 is included. The tuning mesh assembly 5 includes a front cavity tuning mesh 51 disposed on the speaker cover 21, a rear cavity tuning mesh 52 disposed on the rear cavity cover 22 of the speaker, a feedforward tuning mesh 53 disposed on the upper cover of the rear shell 23 of the speaker, and a microphone tuning mesh 54. The tuning mesh assembly 5 adjusts the performance of different frequency bands such as treble and bass by changing parameters such as the size and shape of the tuning holes and the density of the tuning cotton. Furthermore, the tuning mesh assembly 5 also prevents dust and other contaminants from entering the headphones and affecting their sound quality.

[0031] like Figures 4 to 5The illustrated tweeter module includes a horn assembly 1, which comprises a horn body 11 and a horn bracket 12. A tweeter 14 is housed within the horn body 11, and a sound amplification cavity 111 is located at one end of the horn body 11. The horn bracket 12 is installed within the sound amplification cavity 111, and the outer surface of the horn bracket 12 and the inner surface of the horn body 11 form a playback channel 13, which connects to the tweeter 14. The tweeter 14 is an XMEMS tweeter. With this invention, the tweeter in the horn assembly is positioned within the horn body. When the tweeter plays, the sound is transmitted through the playback channel. The horn design concentrates the sound projection direction, resulting in a louder volume and farther sound propagation. This improves volume and projection distance, increases sound production efficiency, controls the sound diffusion angle, and eliminates the need for more expensive horns, thus reducing manufacturing costs.

[0032] As a specific implementation and not a limitation, to make the sound from the tweeter more focused, a speaker mounting slot 15 is provided at the end of the horn body 11 away from the amplification cavity 111. The speaker mounting slot 15 is connected to the playback channel 13 and is used to mount the tweeter 14. The tweeter 14 is disposed in the horn body 11, allowing sound to be transmitted along the playback channel 13. The design of the horn ensures good impedance matching between the internal air pressure and the external ambient air pressure. This matching reduces energy loss and improves the efficiency of sound propagation. When sound passes through the horn, due to the good impedance matching, the sound energy can be transferred to the air more effectively, thereby increasing the loudness and clarity of the sound.

[0033] To further facilitate the disassembly of the horn bracket and better form the playback channel 13, a positioning hole 1111 is provided inside the amplification cavity 111, and a support column 121 is provided on the horn bracket 12. The support column 121 cooperates with the positioning hole 1111 to fix the horn bracket 12 inside the amplification cavity 111. The support column 121 is inserted into the inside of the horn body 11, so that the bottom of the horn bracket 12 fits against the horn body 11, and the size of the horn bracket 12 is slightly smaller than the cavity of the horn body 11. The horn bracket is made of PC material.

[0034] Furthermore, to enable the horn assembly 2 to be quickly installed on the horn cover 21, the horn body 11 also includes a mounting base 112, with one end of the amplification cavity 111 fixed to the mounting base 112. The horn cover 21 is provided with a mounting platform 211, and the mounting base 112 cooperates with the mounting platform 211 to fix the horn assembly 1 onto the horn cover 21. When it is necessary to install the horn assembly 1, simply mate the mounting base 112 with the mounting platform 211. The mounting platform 211 and the mounting base 112 are fixed with an interference fit; appropriate glue can be applied between them for a more secure fixation.

[0035] As a specific implementation and not a limitation, in order to concentrate sound propagation, extend high frequencies, and increase high-frequency bandwidth, the amplification cavity 111 has a small end 1112 and a large end 1113. The small end 1112 is closer to the tweeter 8, and the large end 1113 is farther away from the tweeter 8. The inner diameter of the amplification cavity 111 gradually increases from the small end 1112 to the large end 1113. This shape facilitates the concentrated projection of sound onto the target area, significantly reduces the amplitude of the diaphragm of the speaker, and allows the speaker to achieve lower distortion and linearity even with small amplitude movements. This reduces distortion in the high-frequency range, thereby extending the high-frequency range.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
