Description

Technical Field

[0001] The present disclosure generally relates to a speaker and an electronic device including the speaker. Background Art

[0002] With the continuous development of electronic technology and the increase in consumer demands, the requirements for speakers have also been increasing. For example, speakers may need to meet the following requirements while maintaining a low profile: large load capacity, large displacement, low distortion, audio output with higher sensitivity, and high frequency extension.

[0003] Currently, existing conventional speakers include two separate or suspended wires that extend from the voice coil to the speaker's frame terminals to receive audio signals. The wires should be axially spaced from the speaker's surround and / or spider, and space must be reserved above and below the wires to keep the wires away from other components and prevent potential collisions during operation of the speaker, which makes it difficult to design or manufacture low-profile speakers. In addition, when manufacturing the speaker, in order to ensure proper operation of the speaker and avoid abnormal sounds or noise, the wires should be soldered to the speaker's frame terminals so that the wires between the voice coil and the frame terminals have an accurate length and bend radius. The steps of controlling or adjusting the length and bend radius of the wires between the voice coil and the frame terminals are complex and difficult. In actual production, it is almost impossible to completely avoid defects or poor performance of the speaker due to inaccurate length or bend radius of the wires.

[0004] Therefore, there is a need for a loudspeaker that can meet the above requirements, especially the requirements for low profile and / or easy manufacturing. Summary of the Invention

[0022] Hereinafter, various embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings.

[0023] As used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. As used herein, the terms "comprises," "comprising," "includes," and / or "including" indicate the presence of the stated features, integers, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or combinations thereof. As used herein, the term "and / or" and the symbol " / " are meant to include any and all combinations of one or more of the associated listed items. In addition, although the terms "first," "second," etc. may be used herein to describe various elements, components, steps, or calculations, these elements, components, steps, or calculations should not be limited by these terms, but rather these terms are merely used to distinguish one element, component, step, or calculation from another. For example, a first component could be termed a second component; similarly, a first calculation could be termed a second calculation; similarly, a first step could be termed a second step; all without departing from the scope of the present disclosure.

[0024] For purposes of clarifying use in the pending claims and hereby giving the public notice, unless expressly stated to the contrary by applicant, in lieu of any other implied definition, either preceding or following, the phrase “ 、 ,……and <n> At least one of "or"< / n> 、 、……、 <n>or at least one of the combinations thereof” is defined in the broadest sense by the applicant to mean one or more elements selected from the group consisting of A, B, ... and N, that is, any combination of one or more of the elements A, B, ... or N, including any one of the elements alone or in combination with one or more of the other elements (which may also include, in combination, additional elements not listed).

[0025] As used herein, the term "axis" means a central axis passing through a loudspeaker, a vibration assembly, or a surround, and the term "axial direction" means a direction along the axis. The term "inner" or "inner portion" means a direction, position, or portion that is relatively closer to the axis, and the term "outer" or "outer portion" means a direction, position, or portion that is relatively farther from the axis. The term "vibration support member" means a member that supports the diaphragm and / or voice coil, such as a surround or a spring. Typically, the vibration support member is connected to the diaphragm and / or voice coil at one end and to the frame of the loudspeaker at the other end, and can thus support or position the diaphragm and / or voice coil in their correct positions.

[0026] The present disclosure provides a speaker and an electronic device including one or more speakers. In the speaker, the conductor used to transmit audio signals from an external audio source to the voice coil is formed together with a vibration support member, such as the speaker's surround or spider. Consequently, the speaker lacks separate or suspended wires and, as a result, has a reduced height compared to conventional speakers with separate or suspended wires. Furthermore, the speaker manufacturing process can be simplified by omitting the complex steps of controlling or adjusting the length and curvature of the wire between the voice coil and the frame terminal.

[0027] According to one or more embodiments of the present disclosure, a conductor and a vibration support member (such as a surround or a damper) are formed as an integral part through a vulcanization molding process. The conductor is encapsulated within the surround's rubber material and is well protected by this material. Compared to other processes, conductors encapsulated within the surround formed through vulcanization molding have an extended lifespan, and conductor-related noise is reduced or eliminated.

[0028] < / n> Figure 1 is a cross-sectional view illustrating a speaker 100 according to one or more embodiments of the present disclosure. Figure 2 yes Figure 1 Magnified view of the circled portion. Figure 3A is a top view of the surround 130 of the loudspeaker 100, and Figure 3B It is a bottom view of the edge ring 130.

[0029] As shown, the loudspeaker 100 includes an axis x, a magnet assembly 110, a vibration assembly 120, a surround 130, and a frame 150. The magnet assembly 110 includes a magnet 112, a top plate 114, a yoke 116, and a magnetic gap 118 formed between the top plate 114 and the yoke 116. The yoke 116 has a yoke base 116a and sidewalls 116b extending from the yoke base 116a to define a space for receiving the magnet 112 and the top plate 114 therein. The magnet assembly is arranged so that the top plate 114 and the yoke 116 guide and concentrate the magnetic flux from the magnet 112 to and through the magnetic gap 118. The frame 150 is fixedly coupled to the magnet assembly 110 or the yoke 116 thereof.

[0030] The vibration assembly 120 includes a diaphragm 122 and a voice coil 124. The voice coil 124 is connected to the diaphragm 122 and therefore moves or vibrates together with the diaphragm 122. The voice coil 124 includes a body portion 124a and a coil portion 124b attached to the body portion 124a. The coil portion 124b is at least partially suspended in the magnetic gap 118. In some embodiments of the present disclosure, the voice coil 124 is connected to the diaphragm 122 at its upper end, and the coil portion 124b suspended in the magnetic gap 118 is the lower portion of the voice coil 124. The surround 130 includes a surround body 132 and is formed with a conductor 140. The surround 130 or surround body 132 is connected to the voice coil 124 at its inner end 134 and is connected to the frame 150 at its outer end or outer portion 136. The conductor 140 is electrically connected to the coil portion 124b of the voice coil 124. During operation, an audio signal is transmitted to the voice coil 124 through the conductor 140. In response to the audio signal passing through the voice coil 124 in the magnetic gap 118, the voice coil 124 vibrates in the magnetic gap 118, thereby vibrating the diaphragm 122 connected to the voice coil 124 to produce sound.

[0031] Figures 1 to 2 Specific structures of the magnet assembly 110 and the frame 150 according to one or more embodiments of the present disclosure are shown. However, the present disclosure is not limited thereto. In one or more other embodiments of the present disclosure, the magnet assembly can have any suitable structure so long as the magnet assembly can define a magnetic gap for suspending the voice coil therein and can guide and concentrate the magnetic flux from the magnet into and through the magnetic gap. In one or more further embodiments of the present disclosure, the frame can have any suitable structure so long as it can support the folding ring and the vibration assembly. In one or more further embodiments of the present disclosure, the frame 150 can be omitted and the folding ring 130, that is, the outer end or outer portion 136 of the folding ring 130, can be directly connected to the magnet assembly.

[0032] like Figures 1 to 2 As shown in , each of the conductors 140 includes a conductor body 142 that is tightly attached to the surround body 132 along its entire length. That is, the conductor body 142 is in close contact with and connected to the surround body 132 along its entire length and vibrates together with the surround during operation of the speaker 100. Each of the conductors 140 also includes a connecting portion 144 at its inner end. The connecting portion 144 is attached to the voice coil 124 and electrically connected to the coil portion 124b, and thus, the conductor 140 is electrically connected to the coil portion 124b. Each of the conductors 140 is also electrically connected to a corresponding terminal 160, which is in turn configured to be electrically connected to an external audio source. Specifically, the connecting portions 144 of the two conductors 140 are connected to the positive and negative leads of the voice coil 124, respectively, and the two conductors 140 are electrically connected to the positive and negative terminals, respectively. In other words, conductor 140 is connected to surround 130 and is coextensive with surround 130 at least along its length extending from voice coil 124 to frame 150. During operation of loudspeaker 100, voice coil 124 receives audio signals from an external audio source through terminals 160 and conductor 140.

[0033] Therefore, in Figures 1 to 2 In the embodiment shown in FIG, the conductor 140 for transmitting audio signals to the voice coil 124 is formed integrally with the surround 130, and there are no separate or suspended wires in the loudspeaker 100. Therefore, the loudspeaker 100 has a reduced height compared to conventional loudspeakers having separate or suspended wires. Furthermore, because there are no separate or suspended wires, the process of manufacturing the loudspeaker can be simplified by omitting the complex or difficult steps of controlling or adjusting the length and bending arc of the wires between the voice coil and the frame terminals.

[0034] like Figures 1 to 2 、 Figures 3A to 3B As shown in FIG, the conductor 140 is formed in the surround 130, closer to the bottom surface of the surround 130, or partially exposed from the bottom surface. In some embodiments of the present disclosure, the surround is thickened in an area near or adjacent to the conductor to at least partially encapsulate the conductor 140 therein. In one or more embodiments of the present disclosure, the surround is thickened only in a small area near or adjacent to the conductor, and the performance of the surround is not affected by the local thickening of the surround, especially when the conductor and the thickened area are arranged symmetrically with respect to the center of the surround. As used herein, the terms "encapsulate," "encapsulated," "partially encapsulated," and "completely encapsulated" mean that the conductor body 142 is encapsulated, partially encapsulated, or completely encapsulated within the surround 130, but the inner end or inner portion (connection portion 144) of each conductor 140 extends from the surround for connection to a lead of the voice coil, and the outer end or outer portion (not shown) of each conductor 140 extends from the surround for connection to a terminal of the speaker.

[0035] In one or more embodiments of the present disclosure, the conductor 140 and the surround 130 are integrally formed by a vulcanization molding process. In some embodiments, the molding process may include the following steps: forming a groove in a mold at a position corresponding to the conductor; positioning or securing the conductor in the corresponding groove in the mold; applying a raw rubber material to the mold; and applying heat and / or pressure to vulcanize the rubber, thereby forming an integral surround with the conductor encapsulated in the surround.

[0036] In embodiments, where conductor 140 and surround 130 are formed as an integral part, such as through a vulcanization molding process, the conductor is encapsulated in the rubber material of the surround and can be well protected by the rubber material. For example, any impact or force applied to the conductor can be mitigated or at least partially absorbed by the rubber material encapsulating the conductor. The inventors of the present disclosure have discovered that, compared to other processes, conductors encapsulated in the surround through a vulcanization molding process have an extended or prolonged lifespan without any failures, such as conductor breakage or disconnection. Additionally, because the conductor is encapsulated in the rubber material of the surround, noise associated with the conductor is reduced or eliminated.

[0037] exist Figures 1 to 2 、 Figures 3A to 3B In the embodiment shown in FIG, the two conductors 140 are arranged symmetrically with respect to the center of the surround 130 or the axis of the loudspeaker 100. However, the present disclosure is not limited thereto, and in one or more other embodiments of the present disclosure, the two conductors may be positioned in any suitable relationship. For example, the two conductors may be positioned at any suitable angle (such as a 90-degree angle) relative to each other. The two conductors may also be positioned in a parallel relationship, a perpendicular relationship, or a coincident relationship.

[0038] exist Figures 1 to 2 、 Figures 3A to 3B In the embodiment shown in , each of the two conductors 140 is a single strand of round wire. However, the present disclosure is not limited thereto. In one or more other embodiments of the present disclosure, the conductors can be in any suitable form, such as stranded wire, flat wire, metal film, or metal mesh.

[0039] exist Figures 1 to 2 、 Figures 3A to 3B In the embodiment shown in , the conductor 140 and the surround 130 are formed as an integral part by a vulcanization molding process. However, the present disclosure is not limited thereto.
