The present description relates generally to acoustic devices including, for example, audio modules with wire dampeners.
Audio modules often include a voice coil that includes a wire wrapped around a magnet to form several loops. During operation of the audio module, the voice coil oscillates and drives a diaphragm to produce acoustical energy. However, some sections of the wire are not tightly wrapped and are subject to vibration and deflection during the voice coil oscillation. These sections of the wire can undergo mechanical fatigue. Over time, this can cause damage (e.g., breaking) to the wire. Further, when the wire oscillates at the resonant frequency of the material of the wire, the deflections of the wire become greater, leading to an increased likelihood of damage.
Certain features of the subject technology are set forth in the appended claims. However, for purpose of explanation, several aspects of the subject technology are set forth in the following figures.
The detailed description set forth below is intended as a description of various configurations of the subject technology and is not intended to represent the only configurations in which the subject technology can be practiced. The appended drawings are incorporated herein and constitute a part of the detailed description. The detailed description includes specific details for the purpose of providing a thorough understanding of the subject technology. However, the subject technology is not limited to the specific details set forth herein and can be practiced using one or more other implementations. In one or more implementations, structures and components are shown in block diagram form in order to avoid obscuring the concepts of the subject technology.
Electronic devices, such as mobile wireless communication devices (e.g., smartphones, tablet computing devices) include audio modules designed to output acoustical energy in the form of audio content, such as music, audio tracks corresponding to video content, voices of remote users of electronic devices participating in phone calls or audio and/or video conferences, podcasts, or any other audio content. Audio modules described herein may include components such as a membrane (e.g., diaphragm), a voice coil, and a permanent magnet, all of which are used to produce the audio content. The voice coil may include a wire (e.g., metal wire) wound several times around the permanent magnet, and can interact with the permanent magnet by oscillating and driving the membrane to produce acoustical energy in the form of the audio content.
The wire used to form the voice coil includes an inlet wire loop and an outlet wire loop. During operation of the audio module, these wire loops vibrate with the voice coil. Traditional audio modules do not compensate for vibration and resultant deflection of the wires. As a result, the wires may become damaged, leading to reduced acoustic performance and/or damage to the wires.
In accordance with aspects of the subject technology, an audio module, or audio output device, is provided with one or more dampening components integrated with wires associated with a voice coil. As an example, audio modules described herein include an adhesive, or glue, through which a portion of the wire passes. The adhesive is applied to the wire in an uncured state, allowing the adhesive to encapsulate the wire. Moreover, the adhesive, when cured, includes an affixed portion adhered to the audio module and a suspended portion extending from the fixed portion but not in contact with the audio module. During operation of the audio module, the dampening component reduces the magnitude of vibration and deflection of the wire by dissipating energy (e.g., kinetic energy) of the wire, while also allowing the audio module to generate acoustical energy. Beneficially, the affixed and suspended portions can provide dampening, while the suspended portion can at least partially deflect with the wire, thus providing flexibility to the wire and decreasing the likelihood of damage to the wire.
In another example, audio modules described herein include a semisolid material, such as grease. A portion of the wire of the voice coil passes through the semisolid material, allowing the semisolid material to encapsulate. During operating of the audio module, the dampening component can reduce deflection of the wire. A compartment is integrated with the audio module to receive and generally contain the semisolid material. In some instances, the compartment is positioned in a location corresponding to a relatively high deflection of the wire, thus locating the semisolid material at an area of peak displacement of the wire.
In yet another example, audio modules described herein rely on existing components to store a semisolid material. For example, an audio module includes a yoke and a plate that combine to hold/store components of the audio module. The existing components in the audio module provide a space to hold the semisolid material. For example, the semisolid material can be positioned between the existing components. Beneficially, the required design and engineering changes to an audio module are reduced.
The described dampening components provide the advantage of encapsulating the wire and engaging an outer perimeter of the wire. As a result, each dampening component can conform to the shape of the wire, with little or no space/gap between the wire and the dampening component, thus enhancing the dampening effects of the dampening components described herein.
The electronic device 100 may further include a display 104. The display 104 is designed to present visual information in the form of textual information, still images, and/or motion images (e.g., video). The display 104 may include a capacitive touch input display designed to receive touch inputs and/or gestures from a user. The display 104 may be covered by a transparent layer 106 that is coupled with the housing 102. The transparent layer 106 may include a material such as glass, plastic, or sapphire.
The electronic device 100 further includes additional input features, such as a button 108a and a button 108b. The buttons 108a and 108b can be actuated by a user to depress a switch to, for example, control what is presented on the display 104.
The electronic device 100 further includes several audio modules (e.g., speaker modules). As shown, the electronic device 100 includes an audio module 110a, an audio module 110b, and an audio module 110c. The audio modules 110a, 110b, and 110c are designed to provide acoustical energy output in the form of audible sound. Accordingly, the acoustical energy output provided by the audio modules 110a, 110b, and 110c may take the form of audio content, such as music and audio tracks corresponding to video content, as non-limiting examples. The amplitude (e.g., volume) of the audio modules 110a, 110b, and 110c can be adjusted by user inputs to the display 104 and/or to the buttons 108a and 108b. The housing 102 includes openings 112a and openings 112b that allow the acoustical energy generated by the audio modules 110a and 110b, respectively, to exit the electronic device 100. The transparent layer 106 includes an opening 114 that allows the acoustical energy generated by the audio module 110c to exit the electronic device 100.
Also, the electronic device 100 may include a port 115 designed to receive a connector (not shown in
The magnet 222 may include a rare Earth magnet or neodymium, as non-limiting examples. Also, the magnet 222 may be representative of one or more permanent magnets of the audio module 210. During operation, the voice coil 220 receives an alternating electrical current, causing the voice coil 220 to create an electromagnet with an alternating magnetic polarity. As a result, the voice coil 220 interacts with the magnet 222 by magnetically coupling to and magnetically repelling the magnet 222, based upon the alternating magnetic polarity. When assembled, the voice coil 220 is coupled to a membrane 225, or diaphragm. As a result, the oscillation of the voice coil causes a corresponding oscillation of the membrane 225, resulting in acoustical energy output, i.e., audio content. Although not shown in
While the voice coil 220 oscillates, the wires 224a and 224b move (e.g., vibrate). In order to limit or reduce the resulting deflection of the wires 224a and 224b, the audio module 210 further includes a dampening component 226a and a dampening component 226b. As shown in
The dampening component 226a can partially adhere/affix to the housing component 218b, or another component carried by the housing component 218b. For example,
Also, the housing component 218b may include modifications to facilitate the suspended portion 228b. For example, the housing component 218b may include an incline 232 representing a non-parallel region with respect to the ledge 230. Further, the incline 232 represents a region of reduced elevation of the housing component 218b, as compared to the elevation of the ledge 230. Based on the incline, the suspended portion 228b of the dampening component 226a is more easily separated from the housing component 218b.
While adhesives are used to create the dampening components, other materials can be substituted. For example, a heat-shrinking material (e.g., heat shrink polymer) can cover a portion of a wire, and receive thermal energy, causing the heat-shrinking material to conform to the outer perimeter of the wire. Additionally, a portion of the heat-shrinking material can be affixed to a housing part, while an additional portion of the heat-shrinking material can suspend from the affixed part.
When the dampening component takes the form of a semisolid, the dampening component can be positioned between existing audio module components. For example,
In addition to smartphones and tablet computing devices, audio modules described herein may be integrated into other devices. For example,
The bus 608 collectively represents all system, peripheral, and chipset buses that communicatively connect the numerous internal devices of the electronic system 600. In one or more implementations, the bus 608 communicatively connects the one or more processing unit(s) 612 with the ROM 610, the system memory 604, and the permanent storage device 602. From these various memory units, the one or more processing unit(s) 612 retrieves instructions to execute and data to process in order to execute the processes of the subject disclosure. The one or more processing unit(s) 612 can be a single processor or a multi-core processor in different implementations.
The ROM 610 stores static data and instructions that are needed by the one or more processing unit(s) 612 and other modules of the electronic system 600. The permanent storage device 602, on the other hand, may be a read-and-write memory device. The permanent storage device 602 may be a non-volatile memory unit that stores instructions and data even when the electronic system 600 is off. In one or more implementations, a mass-storage device (such as a magnetic or optical disk and its corresponding disk drive) may be used as the permanent storage device 602.
In one or more implementations, a removable storage device (such as a floppy disk, flash drive, and its corresponding disk drive) may be used as the permanent storage device 602. Like the permanent storage device 602, the system memory 604 may be a read-and-write memory device. However, unlike the permanent storage device 602, the system memory 604 may be a volatile read-and-write memory, such as random access memory. The system memory 604 may store any of the instructions and data that one or more processing unit(s) 612 may need at runtime. In one or more implementations, the processes of the subject disclosure are stored in the system memory 604, the permanent storage device 602, and/or the ROM 610 (which are each implemented as a non-transitory computer-readable medium). From these various memory units, the one or more processing unit(s) 612 retrieves instructions to execute and data to process in order to execute the processes of one or more implementations.
The bus 608 also connects to the input device interface 614 and the output device interface 606. The input device interface 614 enables a user to communicate information and select commands to the electronic system 600. Input devices that may be used with the input device interface 614 may include, for example, alphanumeric keyboards and pointing devices (also called “cursor control devices”). The output device interface 606 may enable, for example, the display of images generated by electronic system 600. Output devices that may be used with the output device interface 606 may include, for example, printers and display devices, such as a liquid crystal display (LCD), a light emitting diode (LED) display, an organic light emitting diode (OLED) display, a flexible display, a flat panel display, a solid state display, a projector, or any other device for outputting information. One or more implementations may include devices that function as both input and output devices, such as a touchscreen. In these implementations, feedback provided to the user can be any form of sensory feedback, such as visual feedback, auditory feedback, or tactile feedback; and input from the user can be received in any form, including acoustic, speech, or tactile input.
Finally, as shown in
These functions described above can be implemented in computer software, firmware or hardware. The techniques can be implemented using one or more computer program products. Programmable processors and computers can be included in or packaged as mobile devices. The processes and logic flows can be performed by one or more programmable processors and by one or more programmable logic circuitry. General and special purpose computing devices and storage devices can be interconnected through communication networks.
Some implementations include electronic components, such as microprocessors, storage and memory that store computer program instructions in a machine-readable or computer-readable medium (also referred to as computer-readable storage media, machine-readable media, or machine-readable storage media). Some examples of such computer-readable media include RAM, ROM, read-only compact discs (CD-ROM), recordable compact discs (CD-R), rewritable compact discs (CD-RW), read-only digital versatile discs (e.g., DVD-ROM, dual-layer DVD-ROM), a variety of recordable/rewritable DVDs (e.g., DVD-RAM, DVD-RW, DVD+RW, etc.), flash memory (e.g., SD cards, mini-SD cards, micro-SD cards, etc.), magnetic and/or solid state hard drives, read-only and recordable Blu-Ray® discs, ultra density optical discs, any other optical or magnetic media, and floppy disks. The computer-readable media can store a computer program that is executable by at least one processing unit and includes sets of instructions for performing various operations. Examples of computer programs or computer code include machine code, such as is produced by a compiler, and files including higher-level code that are executed by a computer, an electronic component, or a microprocessor using an interpreter.
While the above discussion primarily refers to microprocessor or multi-core processors that execute software, some implementations are performed by one or more integrated circuits, such as application specific integrated circuits (ASICs) or field programmable gate arrays (FPGAs). In some implementations, such integrated circuits execute instructions that are stored on the circuit itself.
