Description

Technical Field

[0001] The present application relates to the technical field of loudspeakers, and in particular to a dual-boost push-pull loudspeaker and electronic equipment. Background Art

[0002] A speaker, also known as a "horn," is a very common electroacoustic transducer found in any electronic device capable of producing sound. While the speaker is the most vulnerable component in electronic devices, it is also the most crucial for sound quality. When a speaker is operating, audio energy, through electromagnetic, piezoelectric, or electrostatic effects, causes the cone or diaphragm to vibrate the surrounding air, producing sound. Speakers are categorized as either internal or external. External speakers are generally referred to as sound boxes. Internal speakers are built into devices such as headphones, allowing users to simply wear headphones to meet their audio needs.

[0003] In related technologies, small or micro speakers built into headphones usually only have one speaker, which makes it difficult to achieve a wide sound range from bass to treble and high-quality sound effects with low distortion, affecting the performance and experience of the speaker.

[0037] See Figure 1 and Figure 2 and Figure 5 , is a dual-boost push-pull speaker 100 shown in an embodiment of the present application, which includes a housing 10; a woofer 20, the woofer 20 is arranged at one end of the housing 10; a tweeter 30, the tweeter 30 is arranged at the other end of the housing 10, and the tweeter 30 and the woofer 20 are spaced apart to form a magnetic gap portion 40; a filter 50, the filter 50 is arranged in the magnetic gap portion 40, and the filter 50 has a filter hole 51, the filter hole 51 connects the woofer 20 and the tweeter 30; and a front repulsion magnet 60, the front repulsion magnet 60 is installed on the filter 50.

[0038] In summary, the implementation of the technical solution of this embodiment will have the following beneficial effects: in the dual-boost push-pull speaker 100 of this solution, by simultaneously installing the woofer 20 and the tweeter 30 in the housing 10, since the woofer 20 and the tweeter 30 respectively have their own bass and treble bandwidths, a truly wide overall sound range can be achieved; in addition, a magnetic gap 40 is formed between the woofer 20 and the tweeter 30, and a filter 50 with filter holes 51 is further installed in the magnetic gap 40, and a pre-repelling magnet 60 is installed inside the filter 50 to perform a counter-repulsive magnetization setting with the tweeter 30, so that the pre-repelling magnet 60 can be used to enhance the magnetic flux density of the magnetic gap 40. At the same time, the filter 50 and the filter holes 51 formed therein can form an acoustic low-pass filter structure, thereby effectively achieving an excellent high-quality sound effect without distortion, thereby improving the performance (i.e., sound effect) and user experience of the speaker and the electronic device installed with the speaker.

[0039] In the present application, the housing 10 can be made of plastic or metal. A mounting cavity is formed inside the housing 10, and the mounting cavity is used to accommodate the woofer 20 and the tweeter 30. The inner side wall of the housing 10 is provided with an annular boss protruding toward the center of the mounting cavity. The outer peripheral wall of the woofer 20 abuts against the inner side wall of the mounting cavity, and the bottom of the woofer 20 is clamped to one side of the thickness direction of the annular boss to achieve installation and fixation; similarly, the outer peripheral wall of the tweeter 30 abuts against the inner side wall of the mounting cavity, and the bottom of the tweeter 30 is clamped to the other side of the thickness direction of the annular boss to achieve installation and fixation. The above-mentioned multiple directions constrain the freedom of movement of the woofer 20 and the tweeter 30, which can significantly improve the installation stability of the woofer 20 and the tweeter 30, and avoid shaking, collision, noise, and affecting the sound effect of the extender.

[0040] Please continue reading Figure 1 and Figure 2 In some optional embodiments, an external magnetic speaker is used to be configured to oppose the magnetic circuit portion, and a pre-repulsion magnet 60 is arranged in the middle position for enhancing the magnetic flux density of the magnetic gap portion of the speaker magnetic circuit, and a filter 50 structure with a low-pass filter function is provided. The filter 50 includes a substrate 52 and a connecting plate 53. The connecting plate 53 is arranged around the outer periphery of the substrate 52, and the connecting plate 53 is fixed to the woofer 20 or the tweeter 30. The substrate 52 is provided with a filter hole 51, and the pre-repulsion magnet 60 is installed on the substrate 52.

[0041] The substrate 52 and the connecting plate 53 can be an integrally formed structure or can be detachably assembled. The preferred embodiment adopts an integrally formed structure to obtain higher structural strength. The substrate 52 and the connecting plate 53 cooperate to form a disc-shaped or bowl-shaped structure, which is in contact with the woofer 20 or the tweeter 30 through the connecting plate 53, so that the filter 50 can be installed and fixed, and no screwing or drilling is required, thereby reducing the difficulty of installation. The substrate 52 is used to carry the front repulsion magnet 60, and the front repulsion magnet 60 is located in the middle of the magnetic gap portion 40, so as to better enhance the magnetic flux density of the magnetic gap portion 40.

[0042] Furthermore, there can be multiple installation structures for the front repulsion magnet 60 and the receiving groove 521 to meet different product designs and different usage needs. For example, in one embodiment, the substrate 52 is recessed to form a receiving groove 521, and the notch of the receiving groove 521 is set toward the tweeter 30. The front repulsion magnet 60 is installed in the receiving groove 521, and the front repulsion magnet 60 and the magnetic circuit part of the tweeter 30 are configured to counteract the repulsive magnetization, and the connecting plate 53 abuts against the tweeter 30.

[0043] Or in another embodiment, the substrate 52 is recessed to form a receiving groove 521, the notch of the receiving groove 521 is set toward the woofer 20, the front repulsion magnet 60 is installed in the receiving groove 521, and the front repulsion magnet 60 and the magnetic circuit part of the woofer 20 are configured to counteract the repulsive magnetization, and the connecting plate 53 abuts against the woofer 20.

[0044] The groove wall of the receiving groove 521 presses the outer wall surface of the front repulsive magnet 60 to limit and fix the front repulsive magnet 60 with glue, so that the front repulsive magnet 60 is firmly installed.

[0045] Preferably, based on any of the above embodiments, the front repelling magnet 60 and the speaker's magnetic circuit are configured to form an antagonistic repulsive magnetic configuration, and a plurality of filter holes 51 are provided, with the plurality of filter holes 51 being spaced apart and arranged around the periphery of the receiving slot 521. For example, in this embodiment, the plurality of filter holes 51 are evenly spaced, thereby achieving a better low-pass filtering effect.

[0046] The filter holes 51 can be any of circular holes, square holes, triangular holes, elliptical holes, etc. The apertures of different filter holes 51 can be equal or unequal, which can be flexibly selected according to actual needs.

[0047] Please continue reading Figure 1In some optional embodiments, both the woofer 20 and the tweeter 30 include an inner support 20a, a magnet 20b, an outer support 20c, a diaphragm assembly 20d, and a voice coil 20e. The outer support 20c is mounted on the housing 10, and the inner support 20a is assembled with the outer support 20c via the magnet 20b. The diaphragm assembly 20d is mounted on the outer support 20c, and the voice coil 20e is connected to the diaphragm assembly 20d. The basic components of the woofer 20 and the tweeter 30 are the same. The difference lies in the different matching of materials and performance levels of the voice coil 20e / magnet 20b / diaphragm assembly 20c, which determines that the woofer 20 produces low-range sound and the tweeter 30 produces high-range sound.

[0048] The voice coil (20e) is simply defined as the coil through which current flows. It is a crucial component of the mechanical wave system of an electrodynamic speaker and can be considered the speaker's heart. The performance of the voice coil (20e) affects the speaker's sound intensity characteristics, such as sound level, impedance curve, distortion, transient characteristics, speaker parameters, and sound quality. It particularly impacts the speaker's power handling capacity and lifespan.

[0049] Please continue reading Figure 1 and Figure 2 Based on any of the above embodiments, the dual-boost push-pull speaker 100 further includes a tuning cloth 70 and a connection plate 80. The connection plate 80 is positioned on the top of the woofer 20, away from the tweeter 30. The connection plate 80 defines an air vent 81, and the tuning cloth 70 is positioned at the opening of the air vent 81. The connection plate 80 is used to connect the tweeter 30 / woofer 20 circuit, thereby connecting to an earphone battery or an external audio playback device through the circuit. This allows the dual-boost push-pull speaker 100 to generate a current magnetic field and vibrate to produce sound. The tuning cloth 70, positioned at the opening of the air vent 81, is used to control the amount of air entering the diaphragm assembly 20d during vibration, thereby achieving the desired sound quality. It is understood that when the tuning cloth 70 is designed with different materials, thicknesses, and densities, the air flow rate can be directly controlled, thereby achieving the desired sound quality adjustment.

[0050] Please continue reading Figure 3 In other optional embodiments, the dual-boost push-pull speaker 100 further includes a tuning cloth 70 and a terminal block 80. The terminal block 80 is disposed on opposite sides of the filter 50. The filter 50 and the front repelling magnet 60 are both provided with aligned air holes 81. The front repelling magnet 60 strengthens the magnetic flux density in the magnetic gap by repelling magnetic impulses with the speaker magnet. The tuning cloth 70 is disposed at the opening of the air hole 81 of the filter 50. In this case, if the tweeter 30 is removed, the dual-boost push-pull speaker 100 becomes an independent front-mounted strong magnetic speaker, thereby enriching the product form and variety and meeting the needs of different users and occasions.

[0051] Alternatively, please continue reading Figure 4 In other optional embodiments, the dual-boost push-pull speaker 100 further includes a terminal block 80, which is disposed on the top of the filter 50, and the front repulsion magnet 60 does not need to be opened. It is fixed to the inside of the filter 50 with a repulsive magnet that is antagonistic to the magnetic circuit of the speaker, and the filter 50 is provided with air holes around it. At this time, if the woofer 20 is removed, the dual-boost push-pull speaker 100 constitutes an independent front-end strong magnetic open speaker, thereby enriching the product form and type and meeting the usage needs of different users and occasions.

[0052] In addition to the above, the present application also provides an electronic device, which includes the dual-boost push-pull speaker 100 described in any of the above embodiments. For example, the electronic device can be any one of wired or wireless headphones, music players, tablet computers, etc., and the specific selection can be made according to actual needs and is not specifically limited here.

[0053] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
