Description

Technical Field

[0001] The utility model relates to the technical field of audio, in particular to a double-sided low-frequency drum speaker. Background Art

[0002] The workflow of an audio system begins with receiving sound signals, typically captured via a microphone or other input device. A decoder then analyzes the audio signals and converts them into analog or digital signals. A power amplifier receives these signals and amplifies them to drive the speaker units to produce sufficiently loud sound. Speaker units are the core components of an audio system and are categorized by frequency response range into tweeters, midrange units, and woofers, responsible for reproducing high-frequency, mid-frequency, and low-frequency sounds, respectively.

[0003] Existing speakers generally have single-sided sound. For small speakers that need to be integrated into electric guitars or other musical instruments, due to the limited size of small speakers, they are usually not equipped with complex audio processing systems and multiple speaker units. Therefore, single-sided sound will result in low sound quality, which in turn limits the sound propagation range. To this end, we propose a double-sided low-frequency drum speaker to effectively address the above drawbacks. Utility Model Content

[0004] The purpose of the present invention is to provide a double-sided low-frequency drum speaker to solve the problems raised in the above background technology.

[0006] A cylindrical shell, wherein both ends of the cylindrical shell are open;

[0007] A protective mechanism, wherein the protective mechanism is fixed to both ends of the cylindrical shell;

[0008] an annular mounting shell, wherein the annular mounting shell is fixed in the cylindrical outer shell;

[0009] A double-sided sound-emitting mechanism is fixed in an annular mounting shell.

[0010] Optionally, the protective mechanism includes fixing rings fixed to both ends of the cylindrical shell, and a circular protective mesh cover is fixed in each fixing ring.

[0011] Optionally, a plurality of shock-absorbing soft rubber nails are fixed on the outer surface of the annular mounting shell at intervals along the circumferential direction, and a through-hole corresponding to each shock-absorbing soft rubber nail is opened on the cylindrical shell, and each shock-absorbing soft rubber nail moves through the corresponding through-hole.

[0012] Optionally, the double-sided sound-emitting mechanism includes a dielectric strong magnetic speaker fixed to one end of the annular mounting shell, and a neodymium magnetic mid-bass speaker fixed to the other end of the annular mounting shell.

[0015] Compared with the prior art, the present invention provides a double-sided low-frequency drum speaker with the following beneficial effects:

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1: Please refer to Figures 1 to 3 A double-sided low-frequency drum speaker box includes: a cylindrical shell 1, a protective mechanism 2, an annular mounting shell 3 and a double-sided sound-emitting mechanism 4.

[0029] The cylindrical housing 1 is open at both ends to facilitate sound generation from both sides. The protective mechanism 2 is fixed to both ends of the cylindrical housing 1 and protects the open ends of the cylindrical housing 1, preventing dust and other debris from entering the cylindrical housing 1. Specifically, the protective mechanism 2 includes fixed rings 201 fixed to both ends of the cylindrical housing 1, with circular protective mesh covers 202 fixed within each fixing ring 201. Under normal conditions, the circular protective mesh covers 202 intercept dust and other debris from the outside, preventing them from entering the cylindrical housing 1 and causing damage to the internal structure.

[0030] Furthermore, the annular mounting shell 3 is fixed within the cylindrical outer shell 1 and is used to mount and secure other components. It should be noted that a number of shock-absorbing soft rubber pins 5 are fixed to the outer surface of the annular mounting shell 3 at intervals along the circumference. The cylindrical outer shell 1 is provided with perforations 6 corresponding to each shock-absorbing soft rubber pin 5. Each shock-absorbing soft rubber pin 5 is movable through the corresponding perforation 6 and extends outside the cylindrical outer shell 1. The shock-absorbing soft rubber pins 5 allow the speaker to be connected to other devices through a flexible connection, preventing vibrations generated by the speaker from being directly transmitted to other devices.

[0031] In this embodiment, the dual-sided sound-producing mechanism 4 is fixed within the annular mounting shell 3. Specifically, the dual-sided sound-producing mechanism 4 comprises a dielectric strong magnetic speaker 401 fixed to one end of the annular mounting shell 3. The dielectric strong magnetic speaker 401 is basically composed of components such as a vibrating diaphragm, a magnetic circuit system, a tympanic membrane, a support frame, and an electrical circuit. The strong magnetic field causes the vibrating diaphragm to produce a larger amplitude, thereby achieving higher volume and better sound quality. A neodymium mid-bass speaker 402 is fixed to the other end of the annular mounting shell 3. The high magnetic flux density of the neodymium magnets provides a stronger driving force in the low-frequency range, making the bass more powerful and layered.

[0032] Example 2: Please refer to Figures 4 to 6 The difference between this embodiment and the first embodiment is that:

[0033] The dual-sided sound-generating mechanism 4 includes a treasure box speaker 403 and a runway-shaped bass diaphragm 404 fixed to one end of the annular mounting shell 3. The treasure box speaker 403 is a small speaker launched by BOSE. Its unique design and compact size, but exceptional sound quality, make it suitable for small audio systems. The runway-shaped bass diaphragm 404 is designed to resemble the shape of a runway. Its main principle is to generate low-frequency sound waves through vibration. This design allows the diaphragm to transmit low-frequency sound waves more efficiently during vibration, thereby enhancing the bass effect of the audio system. A circular bass diaphragm 405 is fixed to the other end of the annular mounting shell 3, which can evenly distribute vibration energy, thereby producing clear and rich low-frequency sound waves.

[0034] Example 3: Please refer to Figures 7 to 9 The difference between this embodiment and the first and second embodiments is that:

[0035] The dual-sided sound-producing mechanism 4 includes a full-range speaker 406 fixed to one end of the annular mounting housing 3, providing clear and loud sound, capable of effectively reproducing low, mid, and high frequency bands. A circular stainless steel diaphragm 407 is fixed to the other end of the annular mounting housing 3. This design ensures that the diaphragm maintains a stable shape during vibration, thereby producing clear and accurate sound.
